  The premise of IMEUC is that "without the existence of a free and open competitive market, no de-regulation of existing utility companies can be safely implemented".  For simplification, the discussion henceforth is primarily targeted at the electrical industry only with only occasional references to natural gas or water, but is understood to include those simpler cases as well.

  The problem with all existing attempts to implement de-regulation of electrical pricing (and with existing ?novel? proposals such as EWPC) is that they do not first establish a market for all customers.  Typically a market is established at the wholesale level, but retail (eg. smaller industries, commercial enterprises, and residential), for lack of imagination or concern, are simply "tossed to the retailers", whose only possible option is to add cost without adding value.  What is needed is a market system where every utility customer interacts equally to competitively purchase the product of the primary suppliers (generation and transmission), and distribution and overheads (metering, billing etc.) are done under regulated geographical monopolies.

member photo Dear Mr. Gould,

All deregulation experiments in the USA and elsewhere are not true paradigm shifts from the obsolete vertically integrated utilities (VIUs) paradigm, as they false and maybe trivial things.

Have you established that IMEUC is a true and non-trivial market architecture and design paradigm? Or is IMEUC just an extension of the VIUs paradigm, which could lead to a debacle?

Please complete the outstanding Todd's Test "I would enjoy it if you could itemize your proposal in very simple distinct items (no links) to clarify it."

Best regards,

member photo Ok Jose, once again for those unwilling to read the above referenced articles:

To implement an open de-regulated free market for electricity (etc), it is necessary to enable ALL customers equal access to all suppliers (unlike current pseudo-free-market systems where only a privileged few very large industrials or retailers are allowed to purchase in the LMP market). The "problem" (excuse for this restriction) of high transaction costs for generation / suppliers is eliminated by requiring each customer to pay at a flat rate for the cost of an intelligent robot agent to interact in the market for them, and for the cost of operating the central database system where their purchases are assigned to suppliers, and billings and collections are automatically invoiced and payments recorded.

1) Each customer pays a flat rate of $5.50 / month which covers the cost of i) a new intelligent meter ii) its communication system to the central market database. iii) the cost of operating the central database. iv) purchasing and retiring the existing old analog meters from the distribution entity. The basic unit includes a simple display / keypad terminal mounted inside the premises, and capability to communicate securely with a web browser on the customer's computer. For an added cost, the customer may purchase more elaborate in-premises terminals from the distributor or third party companies.

2) Each (single phase) meter integrates a first motorized local disconnect which can be remotely controlled by the distribution entity to deal with moves / non-payments, and by the customer to handle premises isolation if desired, e.g. for anti-islanding of local generation during a power outage. Comparable control contacts are provided for larger customers.

3) Each (single phase) meter provides to optionally integrate one or more motorized local disconnects in sub-bases which can provide to connect and separately meter either or both local CHP generation and / or one or more PHEV grid-wise electric vehicles. PHEV's are required to include a capability to communicate via power-line carrier with the controller in the meter to identify the paying customer for purchases and to manage re-sales back to the grid. Simpler meters are available to act as parking meters / charging points for business and large public parking lots.

4) Each (single phase) meter includes a premises energy management controller which can communicate, ideally via secure local powerline carrier or wireless lan, with intelligent appliances, thermostats or control plug-ins to use to manage loads during peaks when prices in the market exceed the payer's thresholds, to try to keep the local load curve most economically in line with the pre-purchased options profile, and to implement appropriate responses to ISO / Market Manager broadcast emergency requests. Standards bodies must accelerate efforts to improve communications protocols from controllers to appliances to define what messages are to be exchanged and their meanings.

5) The central market makes available for all reliable next-day weather forecasts for temperature, insolation and precipitation.

f) Local distribution entities become simple geographical pipes-and-wires monopolies, areas assigned by regulators, operation under regulation, with their allowed costs+ per connection point and per unit of product delivered set as today in rate cases based on current well-known formulae.

6) Generation and transmission entities of any size and source become unregulated free enterprises all with equal access to any market they may choose to compete in. The smallest grid-connected solar system of grid-wise PHEV can compete equally to sell into the market at the same price and to the same customers, if they wish, as any large generating entity. Alternatively they might petition the market manager to set up a separate category of "renewable energy" in which only accredited renewable sources can compete and they may be able to get a higher price from ecologically committed customers.

7) All generation transactions are public information, freely accessed by anyone. (customer consumption data only in summary). This is then available for entities considering installing new generation, and for watchdog groups or auditors looking for instances of abuse of market power etc.

8) Customers interact with the market as described in the Part 2 article referenced above. In summary it amounts to purchasing one day in advance "options to consume by category, 15 minute periods" at 50% of the final price of the category. At time of option expiry, the customer may choose to consume the power contracted and pay the other 50% or relinquish the option. Payments for unconsumed options are collected by the market manager and applied to reducing payments for consumed options. Creative market managers may also work out rules/methods to allow advance trading of these options prior to closure.

9) All market interactions can be carried out automatically by the basic programming delivered to the customer in the initial meter installation. If customers choose not to put any settings into the meter initially, it simply observes their typical load profile and does the best it can to accurately predict their next-day load profile based on day-of-week, weather forecasts and recent changes which might indicate guests, vacations etc. Creative third party companies are free to sell to customers better and more advanced meter programs and other options, but all customers are required to purchase from the central market, to keep in place the maximum incentive for peak-load-leveling and to avoid the "free-rider" problem.

10 ) Market geographic areas are set up according to the needs identified by state / provincial regulators, who should probably become the board of directors of the market manager. Markets are organized hierarchically, with areas larger than states operating their own regional markets in which smaller markets etc. may participate as customers. Customers may only participate in the one market to which they are assigned by the regulators / market managers, but generation entities are free to participate in any or many markets at any level they choose.
11 ) Legislators, when setting up this system, should consider establishing an entity which can act as contractor-of-last-resort whose mandate is to monitor and project several years into the future the region's load development, generation mix, etc. and, if provably beneficial to all customers, have the authority to make long-term contracts for new-build generation to guarantee no shortages on the system which would allow absolute unsheddable demand to exceed supply. They would then become responsible to market their contracted purchases into local or neighboring markets or failing that, to asses a clearly identified tax on market transactions to meet the contract payments. This process must be understood to be an absolute last resort action ideally never used, and is only provided to avoid the alternative of economy-crippling shortages (e.g. California), or especially an event of private enterprise encountering an inability to finance large baseload generation in advance of it's entire output being saleable into the market, resulting in less-ideal builds of inefficient plants fueled by vanishing fuels such as natural gas.

12) Other issues can be addressed by reading the articles, or by posting questions here.

member photo It is worth pointing out the "grand design" of the option purchase system, which has the intent with respect of the customer to:
a) reward accurately customer predicted consumption with a somewhat subsidized price.
b) penalize consumption above customer predicted consumption by not subsidizing it.
c) penalize consumption below customer predicted consumption by still charging 50% of the predicted cost for that portion not consumed.

and with respect to the merchant generating entities to:
a) demand absolute reliability to supply those options they've pre-sold in the day-ahead market by requiring them, in the event eg. their facility fails and they cannot supply to a pre-sold option, they must themselves purchase sufficient supply from their competitors to supply the pre-sold options or pay a fee plus any costs to the market manager to organize an equivalent amount of emergency supply or load reduction to balance.

The primary goal of the system is to make the best effort possible to flatten the load curve down onto the most efficient baseload generating units and to fairly reward all efforts to do that, and to penalize those who choose to ignore this imperative. A secondary goal is to encourage to the maximum a significant increase in small distributed CHP units, eg. GE's new N Gas fired SOFC fuel cell CHP units, local solar generation, biomass-fueled stirling CHP generators etc. A tertiary goal is to provide all customers access to the prices now only available to large industrial customers.

member photo also with respect to the merchant generating entities to:
b) eliminate/minimize the need for "spinning reserve" by providing the ISO the ability to quickly and dramatically manage load on a per-feeder basis by broadcasting emergency "for payment" consumption reduction / auxiliary generation startup requests, responses to which are easily reconciled in the market database by identifying and rewarding (with fees charged to the failing entity, generation or transmission, which caused the emergency) those customers who under-consume their pre-purchased options in the emergency period.
c) perhaps also work out a means to handle VAR correction where and when required, esp. with the inverters used by small solar customers which are technically capable of generating at any arbitrary power factor on demand.

Or suppose someone along the way had said, you know, this oxygen-breathing on land is really not sustainable. Why don't I do away with this oxygen-breathing business and grow some gills. I would certainly reduce my own carbon emissions, and my grocery bill would surely decline.

_________________ The point being that, yes, when you know something is going to lapse into partial obsolescence, like railroads, then yes, it's better to move onto something else. That's a pretty tautological message. Is the vertically-integrated electric system at that point? A fair look at the evidence says: hardly.

I never said the site was perfect, just an interesting viewpoint to how to solve your impasse. Both you and Len feel you have the best approach, but the fact is, no one will let either of you implement your scheme. in the REAL world. So it would be wise to simulate it and see how the simulations come out.

The bad news for almost all "change orders" to electricity per the GenCo, TransCo, DisCo and MarkCo model is that the entrenched provider isn't recompensed for their stranded generation capacity, transmission capacity, distribution capacity etc. Therefore your panacea of letting MarkCo solve the world's problems never gets to happen, because of those Billions that have been spent building up the 1st three.

Deregulation doesn't work because the monopoly rightfully asks the regulators for something in the kitty to pay them back for all that stranded plant. Right away, there is a thumb on the scale as the butcher weighs out that meat..

What all this has to do with the title of this article escapes me now.. :)

9.4.07    Jose Antonio,

I have a hard time finding European electricity prices (I know how to find U.S. prices well), but here is what the folks at power engineering recently came up with for 2007 electricity prices in Europe (in U.S. cents per kwh):

Denmark 22.89 Italy 15.74 Germany 13.16 Netherlands 12.62 Belgium 11.43 UK 11.16 Spain 10.35 France 8.54 Finland 6.95 Sweden 6.60

Now, I understand from our mutual friend Fred Banks that Sweden, Finland and France are all heavily invested in nuclear, though he has lamented that Sweden has squandered this advantage.

For comparison's sake, Power Engineering lists the U.S. average as 9.28. That is because of the smart places that rely on central station power run by a utility, and not because of the dumb places that expected something called the "market" to build their power plants and give them a bunch of fancy meters and whiz bang renewables.

Electricity is or should not be a playground for anyone's theories and notions. It is a service essential to modern life. We know a way to provide that service at reasonable rates--central station power. If you are not concerned about the environment, use coal to provide that power. If you are concerned about the environment, use nuclear to provide that power (and yes, build some reserves, apparently they're not too costly or else France would be choking from them.)

The burden of proof is on anyone else if they think they have come up with something better, and I'm not interested in Connecticut being the guinea pig. We've suffered enough from theories and platitudes.

member photo Don G: You MAY have a point. I would certainly far prefer maintaining the old system of vertically integrated monololies operating under price regulation to the "pseudo-deregulation" / "pseudo-free-market" / "EWPC" system which has replaced it here and in many other places. HOWEVER, by keeping it you still wind up stuck with a system where there are a LOT of significant stortcomings. a) incentive to gold-plate the transmission system far beyond necessity. b) no real justification for the HUGE discrepancy between the residential rates and the large industrial rates, set arbitrarily by regulators open to influence by lobbyists. c) no rational incentive for every user to practice intelligent peak-load management to shift loads from costly and inefficient peakers onto less costly and more efficient baseload units. (free-rider problem, e.g. those who DO practice peak shaving wind up subsidizing those who don't. So they demand the regulator assign a payment in liu, but can provide no auditable proof that they actually do what they claim.) d) no fair compensation to e.g. owners of grid-wise PHEV's, solar generating systems, micro-CHP units etc. etc. which distorts the market for those.

Vertical integrated monopoly is obsolete. But given we must replace it, let's use some intelligence (of our own) to apply some intelligence (electronic) to the replacement, which is what IMEUC is doing.

member photo Don G: Further, re: problems with existing vertical monopoly systems... e) there is no way for individual customers to distinguish among themselves their reliability requirement, which results in the regulators enforcing on everyone the costs of providing the reliability demanded by the most vocal, usually a tiny minirity. Under IMEUC plan, you can identify e.g. a small part of your consumption to require 99.97% reliability (your main floor lighting, a refrigerator) for which you pay an appropriate premium. For all the remaining consumption (balance of lighting, cooking, climate control etc.) you can assign it to a much lower reliability category at a lower cost, say perhaps 75% reliability, which means that MOST OF THE TIME you are free to run it as you choose, but IF the market manager requests, you will only operate it on a 75% cycle in any 15 minute period. By this means, the ISO is able to eliminate spinning reserve and other similar costs, which is where the lower price is based. Different customers will have different requirements among these categories, according to economic circumstances, particular events (mother-in-law visiting) etc. f) there is no competitive free market discipline imposed on monopoly operators of generation and transmission, results in over-staffing, high rates of waste in operations, gold-plating of facilities (incentives are to increase costs in order to win rate increases).

many others.

member photo g) IMEUC is also the only strategy which can impose market imperatives on the many millions of unmetered residences (apartments), which then have no incentive to do either conservation or peak levelling. The new meter, designed as it is with an integral load breaker, can easily be configured to replace the main breaker in apartment panels, providing not only instant metering of individual units but also potentially a free load / cost display available to the resident. It is likely even possible to shrink the unit small enough to fit them into existing central multi-breaker load centres typically installed in highrises where there may not be any local mains breaker in the apartments. Perhaps with a modified panel cover, and a single central communications / programming unit serving all meters in the load centre.

member photo Another interesting feature I would like to see integrated into this system is a capability for the meter and the ISO / distribution entity via each meter to EITHER send emails to the owner / customer's designated email address stored in the meter by the customer and changeable as desired, OR perhaps optionally to send broadcast outage information via text messages to cell phones etc. of groups of customers OR make provision for whatever future media may become useful. Emails would be useful when no-one is home due to working or travelling to inform of exceptions (under temperature conditions, appliance failures, power failures, local generator status, out-of-tolerance price spikes etc.) while broadcasts from eg. ISO or distribution would be useful for keeping all customers up-to-date on outages / predicted returns of service etc. Initial estimates could be based on automated sniffing of the SCADA data, with later refinements provided by work crew managers as more detailed information comes available.

Providing the service would cost little to nothing extra with the IMEUC infrastructure in place.

member photo I've been thinking further about Jose Antonio's claim that EWPC provides absolute reliability. How could that be done when new / replacement generation is only built by private investors competing for capital, existing plants wear out requiring replacement, connected load and demand may grow. You will probably claim that the retailers will deal with that through demand control, but I doubt that is true because the retailers are free to sign up customers using cheap-to-meter flat-rate-per-unit contracts. Since that contract is the most profitable for the retailers, that is what they will do. (See most "de-regulated" markets in N. America.)

EWPC doesn't work.

Here is an interesting potential addition to the development of IMEUC. "Penn State engineers have shown that a white-LED system for lighting and high data-rate indoor wireless communications, coupled with broadband over either medium- or low-voltage power line grids (BPL), can offer transmission capacities that exceed DSL or cable and are more secure than RF."

The concept is that White LED's used for lighting, when powered by an electrical network e.g. house wiring, wiring in commercial spaces which carries BPL signals, will themselves broadcast that signal in the light they produce. This enables wireless data delivery at bit rates up to 1 gigabit-per-second to any illuminated terminal configured to receive the signals. A very interesting concept, though not directly related to energy management / peak load management. Perhaps it points the way to future auxiliary revenue streams.

member photo In his Sept. 28 article on EnergyPulse, "The Critical Role of Advanced Metering Infrastructure in a World Demanding More Energy", Eric Miller raises the issue of the amount of data storage required for the central market to manage all the interval data. He states: "AMI solutions generate a lot of data. Consider this math for a mid-sized investor-owned utility using an AMI system to read their meters every 15 minutes: one million meters multiplied by four reads an hour multiplied by 8760 hours in a year equals 35 billion meter reads in a year. That's an enormous amount to read and certainly more than the 12 million monthly consumption reads performed just for billing. Clearly, utilities need a new way to manage and apply all this new data."

So let's calculate exactly the numbers for 1 million customer meters on 15 minute intervals for one year. Let's assume the data is stored in a standard relational database and the specification requires that one year of historical data detail must be maintained online. Let's assume the following table structure for this data:

CREATE TABLE METER_DATA (METER_ID NUMBER(10,0) NOT NULL, READ_DT TIMESTAMP(0) NOT NULL, PREDICTED_WATTS NUMBER(10,0) NULL, CONSUMED_WATTS NUMBER(10,0) NULL, CUSTOMER_ID NUMBER(7,0) NOT NULL, SUPPLIER_ID NUMBER(10,0) NOT NULL PRIMARY KEY (METER_ID, READ_DT) USING INDEX PCTFREE 10 INITRANS 2 MAXTRANS 255 TABLESPACE avail_index STORAGE ( INITIAL 163840 NEXT 163840 PCTINCREASE 0 MINEXTENTS 1 MAXEXTENTS 2147483645 ) )

We can presume that the database system can store numeric data in internal binary numeric form, so any positive integer up to 2 billion will require only 4 bytes, a Date+Time will require 8 bytes, each meter has an associated scaling factor to handle a broad range of possible customer sizes, and the entire data structure is stored on the primary key index. This results in a row storage requirement of 30 bytes per row.

The outcome is that 1 day's 15 minute interval readings generate for 1 million customers generate 2.9 gigabytes. 31 days = 90 gig. 12 months = 1,100 gig. Assuming a 250 gig disk drive costs $200 (my desktop at home has two of those), and all data is stored in a RAID1 array which duplicates all data, requiring 2,200 gig per year, the total year's disk storage costs 2,200 / 250 * $200 = about $2,000. That's about $0.002 per customer per year. Of course there will be additional data structures required, so let's quintuple that amount, to $0.01 per customer per year. Still not fearsome.

member photo Just a bit of further reinforcement of the above discussion of data storage costs:

"Building on Philips long consumer electronics heritage, the revolutionary new drive features an ultra-fast eSATA interface that is six times quicker than the industry-standard USB 2.0, giving users immediate, additional capacity to store more of their music, movies and photos than ever before.

The SPD5130 hard drive has a pioneering single-disk form, allowing for significantly smaller dimensions than the double-drive solutions currently on the market. It will be available to buy in Europe and the US in the summer, priced at 449 EUR and 499 USD."

http://www.physorg.com/news100351474.html

My first "estimate" calculation above was based on a unit storage cost of $200 / 250 gig, or $0.08 / gig . This Philips hard drive includes power supply and high-speed buffered serial data interface for $0.05 / gig. Result is the customers may have not quintuple the absolute storage required / year for $0.01 each, but eight times the absolute storage required. Data storage is a non-issue.

member photo In reviewing again IMEUC's strategy for preparing dispatch orders for generating entities, it appears to me there are possibly ways to improve things for generating companies by further modifying the LMP-like market system used to establish the merit order for each 15 minute interval. 1) the first issue to be addressed is how peaking /dispatchable intermitent units put in bids. 2) the second issue to be addressed is bid structure for each round of ISO dispatch determination.

1) peaking /dispatchable intermitent units bids

The operators of these units, typically simple cycle gas turbines or small distributed generation, need a better method of bidding than just a simple "electricity price per interval" system. The operator's requirement is to cover their fixed and variable operating costs plus a risk premium for being dispatched on too short an interval plus a fair profit each day if possible. Having to bid into the market a day in advance in 15 minute intervals exposes them to significant risk of short dispatch periods, a premium for which they must then add to their offer price, often unnecessarily if the market made provision for this. A probable scenario with the unmodified bid market system which demonstrates the problem is a situation where the operator cannot predict in advance how many hours of operation they might win in the next days market, nor what starting time they might be assigned. The result is that they will logically estimate the shortest operating time they are likely to win the next day, distribute their fixed costs + profit over that "shortest" period, add in their variable costs, divide by their output capacity and arrive at a unit price / kwh which is then bid into every interval of the entire day. Though no rational economist would likely argue that they should bid lower, this still results in their bid being higher than it could be to satisfy their requirement for a fair return, because on most days they will actually be dispactched for a longer period than their estimated "shortest" period, resulting in an over-return of their fixed costs and also in their often being priced out of the market sooner than they might wish.

What I propose instead is that the format of the bids to be submitted for peaking power would be a single dollar - per - kw figure for startup of the unit, plus a dollar - per- kwh figure which should only cover their variable costs. The ISO / dispatcher then, in preparing the merit order for the following day, first calculates the load curve based on customer estimates submitted, then, stepping through the day interval-by-interval, when finding the next-interval's load exceeds then-available generation, then determines how much time the next unit will need to run, then runs through all un-dispatched generation calculating the bid prices for each by distributing their startup bid across that interval, then adding their overhead bid. The dispatcher program then selects the next unit to dispatch as the one which provides the lowest cost-per-kwh for that interval.

2) bid structure

Some units may benefit by having the option to bid a single unit in several ways for a given day. Specifically it could make sense to provide for one or more less-than-a-specified-minimum runtime penalties as part of the operators bid which the dispatcher must add to the period cost in the above calculation if the dispatched period is less than the bidders specificed minimum time period in the bidder's specified interval. Another possibly useful bid option might be to provide for an under-hours-per-month penalty on dispatch, e.g. "if the dispatch history for the past 30 days in total is less than xx hours, then add $yy to my fixed-cost part of the bid". Whether this system would become too complex for bidders to understand or for anyone to audit is a definite concern.

Here's an excellent primer for anyone interested in how current electricity markets work (and don't work).

member photo Jim Beyer has been kind enough to ask the following quiestions regarding IMEUC. I'll post his questions and my responses follow:

To: Len Gould
Subject: IMEUC

Len,

Based on your comment, I decided I should try to get my head around
IMEUC. So I looked at your papers. I still find it a bit obtuse. Much
text was devoted to the particulars of meters and their costs. I think
people concerned with replacing the status quo would be concerned about
many other matters as well.

A few points/questions/comments:

1. The Market Manager is a controlling entity of some sort, so I don't
think you can call IMEUC unregulated in the broad sense of the word. A
concern about deregulation is that new power company X cuts a sweet
heart deal with Factory A, giving them electricity at a low, low, price,
because they aren't bothered with the infrastructure needed to support
all the unprofitable contracts, namely the average residential customer.

2. If there is an open market, what keeps the power plant from saying
no? If Jim wants power, but he doesn't use much, and the infrastructure
access is expensive, why don't they just say no? Someone has to force
them to say yes, because otherwise I would be out of power.

3. Some mechanism is needed to decide on long-term builds, in a
coordinated fashion. If two different companies decide to build plants
to service the same growth opportunity, then they both lose. I know in
normal business this is called "capitalism", but one is already forcing
these companies to service unprofitable users. I think in California,
the companies focused on the profitable accounts, and let the typical
user suffer. Eventually, when no additional capacity strained the grid,
everyone lost.

4. I can accept that the residential customer is a huge loser. I just
don't know by how much. One can see how the residential customer is a
bit two-faced in their demands: "How dare you raise the cost of my
already-heavily-subsidized electrical rates!"

5. I think IMEUC is heavily focused on the residential user, whereas (I
think) the typical utility works to ignore this user as much as
possible, because they are expensive and never a source of profit to
them.

6. It possible that if you look at the bulk of electricity actually
distributed, the amount of energy actually provided that would be "in
play" from a price standpoint is probably very small. Businesses and
factory need their power, and are not likely to quibble about price at
that much, and at least not on a daily basis.

Anyway, just a few thoughts. It's very possible I'm missing something
about your plan. It wouldn't be the first time.

member photo Just a few clarifications Jim:

1a) The Market Manager is not in any way a regulator. Their only interaction is to own and operate the metering and market system, contract for the billing service, collect and distribute payments for provision of energy.
1b) No "sweetheart deals" as now happen under "retailer de-regulation" because of the market rule which states "every customer must purchase from the market to which they are assigned".

2) I presume you mean for new services in difficult locations. IMEUC says nothing to help. It would be Jim's responsibility to arrange and pay for any infrastructure required for his new service. I see no reason all closely-built attractive customers should subsidize Jim's country mansion.

3a) In IMEUC no-one is already forcing these companies to service unprofitable users. All customers in a market region are subject to the same market. There is built-in provision for pre-payment terms, e.g. "pay-first-then-use", as used to be in Britain with coin-operated meters, for deadbeats with the remote-disconnectable meter and communications capabilities.
3b) Re- overbuild in a region, that is entirely up to the capital markets. Ideally open market-based access to all transmission could enable temporary justified overbuild to sell into neighboring markets until local consumption re-economizes a build. However, given the approach of PHEV's switching a large portion of transport fuel onto generation (which could double present demand) I see this as not a serious issue.

4a) I think you err in your estimation. When most existing utilities are generating e.g. 90% of their power with long-paid-off baseload assets which can put out for e.g. $0.03 / kwh, transmission and distribution total cost (at least here in Ontario) adds about $0.04, and residential rates are $0.11, I think everyone's doing quite well. For your area, find out what the large industrial rate is, assume 1/3 of that pays T&D, so assume that large generation is pleased to produce for 2/3 of the industrial rate. Add $0.04 to that for residential distribution costs, and compare it with your actual bill. Are they loosing money? Probably the peakers are if they're not owned by a large baseload, so whoever creates the peaks is creating the problems. That's largely commercial offices, single-shift industrial, and residential A/C.
4b) The big point of IMEUC is it eliminates peaks, flattening the load curve out so the extremely costly (per unit energy) peakers are eliminated. It does this by i) enabling integration of grid-wise PHEV ii) rewarding fairly customers who can shift loads from peak periods to off-peak periods. Whereas under any other market, such well-known technology as making ice in storage at night and shutting down the refrigeration during day peaks is simply not justified because there's little or no difference between night and day electric rates, under IMEUC with a real-time rate, when it comes time to start up that gas-turbine peaker and the rate jumps from $0.07 to $25.00, you WILL very quickly discover who can most economically shift loads off-peak. It will require some adjustment time, and some additional build of high-efficiency baseload generation, but it will happen, and quickly. Eventually the load curve should completely flatten, with the price settling to a point just a bit above present off-peak rates (due to the need to pay off about a 25% new build of baseload generation).
4c) The other point of IMEUC is to eliminate the haggling over "how much wind etc. generation can the grid handle"? With good demand management at every customer, wind can run full whenever the wind blows, solar can generate whenever the sun shines, and customer systems will be pre-organized to exploit the opportunistic availability of excess generation whenever it happens.

5) You're right, IMEUC largely concentrates on bringing the smaller customers into the market, which to now has been the exclusive preserve of the largest industrials. It's an equality thing as much as anything.

6) I believe you're wrong about what proportion of electricity consumption could be "in play". It will certainly take a little time to get the controls, thermal and vehicle battery storage, smart appliances, home CHP engine/generators etc. etc. etc. systems in place, and that needs to be considered, but without the market, the others are seriously handicapped, which is a dumb thing for our society to have happen especially with the present world petroleum situation.

member photo 4d) It's also noteworthy that once the load curve becomes essentially flat, with all generation done by continuous baseload units, there will be no excuse to declare solar photovoltaic enegry worth $0.42 / kwh, as is now the case in Ontario based on the excuse that it mostly supplants costly peaker kwh's. The difference between whatever the politicians want to pay solar generation and the price the market values it at will need to be made up as an explicit subsidy which I think is a better system. The only thing which distorts a market more that a subsidy is a hidden subsidy.

Regarding #2:

No, I didn't mean new construction. I meant marginal areas that are unprofitable to service, and are only serviced because the regulated electrical utility is forced to do so. I think a similar issue arises with the Postal Service, which has some routes which are extremely expensive to service, but overall they can make money delivering mail. (The same could be said about health care in the U.S.).

An example might be a rural setting, very little power sold to several homes on a long transmission line - so lots of maintenance for little return. You really have two options: 1) Make the utility service it (i.e., make them subsidize the cost of maintenance) or 2) Make the customer pay their higher access rate (i.e. maintenance on many miles of transmission line that services very few people).

Another issue regarding #1

If a small A utility can produce 100 MW at 10 cents, and a larger utility B produces 900 MW at 20 cents, then everyone will want power from the smaller utility. But if the 1000 MW worth of demand, how is this decided? Do customers bid up? Do you have a dutch auction or whatever and everyone buys 10% from A and 90% from B? This is how a single large user (such as a factory) might buy up all the cheaper power, perhaps by agreeing to certain conditions that smaller user would not. It would seem that cherry-picking deals might still be finessed through the system (via a quantity-discount arrangement, which most providers and some customers may insist on having).

member photo Jim: Thanks for the followup.

Regarding your first, "a rural setting, very little power sold to several homes on a long transmission line". Under IMEUC, as stated, there is no reason that any existing distribution system should be disturbed at all, except that distribution becomes a standalone enterprise which must recover it's costs and profits by a direct (and easy-to-identify) separate regulated monthly flat fee on your electricity bill insted of being buried within the energy charge. That's the way things work now in all of Ontario in about 90 separate distribution regions/businesses, many of them very long runs to serve rural areas. It works well enough that one hears few if any complaints about re-regulation on that score. The energy prices paid to retailers, though, is a common sore point.

To your second: "If a small A utility can produce 100 MW at 10 cents, and a larger utility B produces 900 MW at 20 cents, then everyone will want power from the smaller utility. " Under IMEUC, as with all current re-regulation systems, the so-called "Standard Market" works by paying every provider of electricity the price bid by the highest-priced provider required to maintain a reliable supply. In your example, as long as the total load in the market being considered remained below 100 kw, the price paid to generation would be 10 cents, with the smaller provider selling 100 MW. As soon as that 100 MW load is exceeded, the price paid to BOTH the small supplied and the large supplier will be 20 cents with the larger provider selling any excess of what the smaller generator can supply. This is a well proven least-cost fair market pricing strategy PROVIDED there are several competing providers and none can control more than perhaps 33% to 50% of the market (not the case in your example).

No large factory would be allowed to make a direct contract with a generator outside of the market, because of the stated rule that "all customers must purchase from the market to which they are assigned." I can see no reason that this rule should be broken, or that any customer should ask that it might be. If an industrial need long-term assurance of costs, they should be able to purchase hedges as insurance separate from the market.

Len: ....

You are right, my only objection is cost. The government may be in denial about energy, but all the predictive models for future energy prices that I use are showing that unless the US goes into (deep) recession, energy prices are going to increase in real terms for the foreseeable future, with the curve getting steeper with time.

I actually think that smart meters are the way to go for all forms of consumption, as I reckon that that for most consumers it will save them a lot of money in the long run. It makes absolute sense for people to control demand and utilise off-peak electricity to minimise the cost. From the utilities' point of view as well I think that smart meters make sense. The infinitely better data flow the meters generate can't but help them manage the grid and target investment more precisely.

It's with regard to DG inverter/meter units that I have my doubts. There is a big difference between smart consumption meters and smart DG meters. Whilst the former are actively managed, they are primarily processing, sending and receiving data which does not have to be dealt with instantaneously. The latter require active management generating an instantaneous response from the connected equipment, which I understand requires a much greater level of processor control and 99.999% reliability and which substantially increases the cost. However, if you know otherwise I would be really interested to hear – I don't pretend to stay on top of developments in the field

There is also the issue of the cost of managing the grid. My understanding is that the cost of managing the grid is proportional to the number of interventions the system operator makes. If millions of actively managed DGs are connected to the grid, there are millions more interventions required. Obviously this can be rationalised by installing processor equipment at grid nodes, but the number of interventions is still huge. This is brought into perspective when it is realised than most sub-50MW generating plant that I have been involved with are not actively managed by the system operator – they have relatively simple SCADA systems that switch them off if they are out of sync, power factor or voltage goes out side limits etc. 50 MW is equivalent to 25,000 buildings with average size DG systems. If it works for small scale commercial generation embedded in distribution networks, it should also work for DG.

This does not address the issues of power quality caused by solid state inverters or large amounts of variable generation. I do not pretend to know what the answers are, or how much it will cost but I know that addressing it will be essential if large amounts of DG are to be possible.

Finally, regarding a flat charge for paying for the grid. I have seen this issue addressed in the past, and each time the politicians have shied away from mandating it; flat charging impinges disproportionately on the poor, whereas apportioning grid charges to each unit of power sold means that the rich subsidise the poor (because people like Mr Gore tend to consume more power). I offer no opion as to which is right, merely the observation that it will depend on where the politicians think the votes are.

member photo Adrian: "There is a big difference between smart consumption meters and smart DG meters. Whilst the former are actively managed, they are primarily processing, sending and receiving data which does not have to be dealt with instantaneously. " -- I'm not sure this is a valid objection. It has been my concept (needs proving) that all control signals from grid management to the DG crowds can be broadcast signals, e.g. single send to all in an area, no confirmation messagegrams, to which the meters would be programmed to respond with the appropriate action (raise the voltage, improve the power factor, etc.) Ideally each message requesting an action would be accompanied by a market price which the grid operator would be willing to pay for the action, and the DG's response would be dependent on price and local circumstance.
I've also been thinking about your other objection, that local voltage control will be difficult with a large proportion of grid power being supplied by eg. small residential DG units. That is a given, IF the installation of them is uneven, e.g. a high concentration of them in a given neighbourhood wanting to feed excess power out to other neighbourhoods. The problem is that, if say 27,600 volts on a substation bus is capable of supplying a 5 mile long 100 amp 3 phase feeder to a neighpourhood with e.g. 17,000 amps at 234 volts with a 2% voltage drop, then the neighbourhood's 34,000 amps peak of DG units get active and try to feed 17,000 amps excess power back into the substation, then they must raise the local voltage in the neighbourhood by at least 4% (in order to compensate for the 2% drop which customers were seeing on the power coming in + the 2% drop they encounter feeding back out). That 4% increase in voltage will be perceived locally as a voltage change from 234 volts to 243.4 volts which might become a difficulty. The 2.1% increase required to feed just a small excess back into the grid is likely very acceptable without any action and would cover almost all neighbourhoods.

I see sevaral mitigating factors. a) That voltage change is a worst-case extreme event, not likely to happen in many locales and in fact quite acceptable even if nothing is done about it. It could become significantly more problematic with a simgle large DG unit at the end of a long feeder but that's not really the condition we're discussing, and can be handled by requiring the large single unit to singal the substation for a tap-change every time he starts up. b) If a particular neighbourhood begins to approach these conditions then the distribution grid operator needs simply to install directional sensors on their substation transformers and adjust their tap-changing logic to handle the case. c) Worst case, a program can be set up to regularly take instantaneous sums of meter readings for all meters identified to be on particularly sensitive feeders in the central database once every 5 minutes. Substation actions (tap changes) can then be made based on sum of current flows with reasonable expectation of accuracy. d) It is also obvious to have the communicating meters record local voltage as well as wattage centrally, and have a program at the central database scan a small representative sample of neighbourhood voltages to determine if tap-changing actions are required at given substations.

The only significant change in control strategy required is that the voltage management mechanism needs to be designed to expect bi-directional power flows, whereas they presently likely only deal with single-direction flows. The tap-change required to fix an over-voltage condition for a customer is opposite if the customer's feeder is flowing power out than it would be if the feeder is flowing power in. It's just a minor upgrade in controls, however, and not likely required very often, especially for the first ten years or so.

Also, regarding your last: "Finally, regarding a flat charge for paying for the grid. I have seen this issue addressed in the past, and each time the politicians have shied away from mandating it; flat charging impinges disproportionately on the poor, whereas apportioning grid charges to each unit of power sold means that the rich subsidise the poor "
The separation of distribution from generation, transmission and (retail if used) into a regulated monopoly on geographic boundaries should be considered an absolute requirement for competitive electrical systems. Otherwise the liklihood of the distribution owner making mischief for his competitor generators or retailers is just too much, and too difficult to monitor. I think your fears of problems are far over-emphasized. Here in Ontario we did it with no complaining at all anywhere (at least on that score) The province now has about 90 separate regulated distribution companies mostly private, some rural co-op. There is also now a fair bit of consolidation going on among them, which makes sense. Britain also. It works very well. The cross-subsidy thing is a red herring, I'd think.

I would also point out that the 100 tenants of a single-meter apartment building are probably subsidizing the distribution of the McMansion suburban estates, not the other way around.

Dick Maclay 11.3.08

Len, my point is that regulators will hold hearings on your proposal and take in other points of view about how things should be done. They will then compromise between your proposal and the others, and add some changes of their own. You may not even recognize IMEEUC in the resulting decision. No matter how well the resulting mish-mash is programmed it will not function the way you envision. Perhaps I have witnessed too many regulatory hearings and become too cynical. But progress in other industries occurred only when people were allowed to circumnavigate the regulators. So I believe my cynicism is justified.


Len Gould 11.4.08

Dick: The details of IMEUC aren't that important, provided the few core principles are maintained. 1) Customers must be required to purchase their electricity in the single market to which they are assigned 2) competitive generator wholesalers sell into any market they wish. 2) The system should explicitly not rely on middleman "retailer/hedger" entities, though perhaps not bar them, as they have a financial incentive to allow their customers to "free ride" on the demand management of others by writing "flat per-kwh fee per month" type contracts which require no customeer equipment investment. 3) Distribution must be operated as a flat-fee regulated monopoly isolated from generation. 4) Transmission is a responsibility of generation, either wholly owned and dedicated to one station, or costs proportionately shared among generation entities by a formula coded into the billling system, but not regulated. 5) Generation are responsible for arranging required transmission to deliver contracts. 6) Dispatch orders expect 100% fulfillment, with heavy financial penalties imposed for unmitigated non-delivery. Emergency situations can be mitigated by a) arranging and paying for alternate supplies to satisfy b) arranging and paying the costs of sufficient demand control among customers in the region/market affected. 7) Every generation entity, from the largest nuclear station to the smallest home CHP unit, are treated equally in the market by the same set of rules. 8) In general, the goal is to operate the grid with little or no excess generation and a much more flat demand curve, depending on customer load management responding to market prices to deal with that, including under conditions of heavy penetration of unreliable generation and PHEV/EV charging.

The goal is that the market will discover what aggregate value customers place on reliability, unreliable renewables, microCHP etc over time and as fuel prices-availability issues develop. with no political / regulatory interference.

Dick Maclay 11.4.08

Len, as was the case in natural gas regulation the devil is in the details any time regulators or politicians get involved. So when they mess up some of your principles things can go very wrong. Worse yet regulators do not learn from their mistakes in a timely manner. So while I find the core principles of your proposals attractive, I continue to believe we need to implement them in a manner that will allow a market to evolve without depending on regulators to get anything right. Just setting up generation and distribution as you suggest requires more than we can expect from regulators, so the best hope is that the wires businesses will evolve over time in response to market forces. Far from perfect but the best I believe we can expect. So we differ primarily in our expectations regarding regulators.


Len Gould 11.4.08

Dick: The way I am seeing IMEUC implemented has no dependence on any regulators whatever. Because the system changes required are so broad, it will need to be implemented by legislation of the political entity with authority, eg. state or national government depending on a country's constitution. The legislation must be drafted to conform to the goals I've stated above. The same legislation then makes the present "regulator" bodies simply the board of directors of the Market Manager entity, with the responsibilities and authorities described in the defining documents.

Dick: I should also point out that though most of the discussion of IMEUC concerns its application to electrical markets, I see it actually being implemented to market electricity, natural gas, and perhaps water in certain dry areas, simultaneously. Once the database and communications systems are in place, adding reading of additional meters costs nothing. Reasoning: 1) The "site controller" function should include the "gas to electricity spark spread" in its decisions regarding starting up local distributed microCHP, and with rapidly developing SOFC fuel cell generators or Stirling CHP boilers, and with "Einstein Refrigeration" or absorption refrigeration A/C using the waste heat, this should become the primary use of all remaining natural gas. 2) Most people don't recognize it but gas is increasingly becoming subject to many of the same "peaky load curve" problems as electricity, requiring oversized infrastructure and source supply from storage to handle the market fluctuations. 3) Esp. in markets such as the UK, rational rationing are very shortly going to become mandatory. IMEUC can accomplish that automaticaly.
