Facts Not Fiction – Debunking Claims of Net Metering Harm
The Senate Consumer Affairs Committee held a hearing this week (Jan 28) to receive testimony on what is causing energy prices to increase. Rather than talk about the main drivers of increasing costs – such as the massive and expected increase in transmission costs driven by last year’s 10-fold increase in capacity prices from the PJM base residual auction – the representative from First Energy (Joanne Savage) attempted to blame net metering instead. She testified that the Price to Compare (“PTC”, the price paid by customers who do not shop for electricity) will increase because of net metering. Once you unpack her testimony, however, it is obvious that her theory is inaccurate and was intended to mislead the Committee and the public. The purpose of this post is to unravel the fallacy of FirstEnergy’s testimony.
In order to understand the deception, it is necessary to understand the “PTC”. The mechanism for calculating the PTC, sometimes referred-to as the default service rate, is established by regulation. See 52 Pa. Code § 54.182. The PTC is supposed to equal the “sum of all unbundled generation and transmission related charges to a default service customer.” Id. One major component of the PTC is the cost of the energy used to provide default service, but in the past several years, transmission and distribution costs have increased at greater rates than the energy cost. Electric utilities typically engage in what are known as “full requirements” service contracts for default service, which are a complete package; energy, ancillary services, and transmission which delivers the energy to the utility at specified locations from where the utility’s distribution network carries the energy to the customers. To recap, the PTC is the cost of the energy and the cost of transmitting the energy to the utility distribution system. There are other administrative costs but those are negligible in comparison.
Net metering is a program authorized in the Alternative Energy Portfolio Standards Act, (“AEPSA”) through which a Customer-Generator can produce more energy than it requires and deliver the excess to the utility for distribution to other customer. The utility then compensates the Customer-Generator at “full retail value” for the excess. 73 P.S. § 1648.1, et seq. While full retail value arguably should include distribution charges, the Public Utility Commission (“PUC”) determined in its regulations, that for purposes of net metering compensation, full retail value equals the PTC. The PUC’s logic is that the PTC represents the cost of energy delivered to the distribution system and Customer-Generators do the same thing – they provide energy to the utility distribution system – so the measure of full retail value for Customer-Generators is the PTC. In short, the utility sells the excess energy at the PTC at the same time that it buys energy (again, at the PTC) from Customer-Generators.
The slight of hand in Ms. Savage’s testimony, was in the discussion of “PTC Prices” as being higher than wholesale prices and then suggesting that because Customer-Generators are compensated at the PTC and not a wholesale rate that the difference is a “cost” to customers who pay the default service rate. That is simply wrong and easily disproved. First of all, the PTC does not change based upon how many Customer-Generators are on the system, period. That is, regardless of whether there is one Customer-Generator on the EDC system or 1000, the customers pay the same PTC, which is derived from auction prices for default service load. The cost of the energy that is purchased from Customer-Generators, the PTC, is the exact same price that retail customers pay for that energy. It is a wash. To suggest that because the PTC is greater than the wholesale rate, default service customers bear a cost associated with Customer-Generators is a false statement, as is the notion that eliminating net metering will reduce energy costs paid by consumers. It will not. Importantly, the PUC collects reports from every utility that would provide specific numbers if this were happening. Despite repeated requests for the PUC to simply produce the reports, they have not.
Ms. Savage’s mathematical gymnastics begin with suggesting that a customer generator could earn $350,000 more being paid the price to compare as opposed to being compensated at the “wholesale rate”. She then labels that $350,000 difference as a cost to customers; it is not. The price to compare is set based on the results of wholesale auctions and the costs of providing default service; and payments to customer generators are not part of the PTC except to the extent that buying energy produced locally by customer generators reduces the cost of transmission and actually lowers the PTC. Adding the alleged $350,000 per customer generator into the costs recovered by the PTC and then recalculating the PTC is double counting and is the only way the PTC could rise to $89/kwh in 2030 – it will not. The difference between the PTC and the wholesale rate is already accounted for in the PTC and adding it again is wrong. The chart found in Ms. Savage’s testimony aptly demonstrates this fallacious formula.
Rather than demonize net metering, it should be recognized for the benefits it provides. It can provide energy in rural areas that may have reliability problems, and distributed generation reduces capacity costs for all customers, because it avoids the use of the transmission system. Moreover, customer generators pay for the system upgrades that are needed for them to interconnect, a benefit to all customers.
