Michigan OKs Gas Decoupling Pilot
Rejects Other Special Rate Mechanism Proposals
Weekly Update Courtesy of URN #3973: In the course of a natural gas base rate proceeding, the Michigan Public Service Commission has authorized the utility, Consumers Energy Co., to institute a revenue decoupling program on a trial basis. However, several other special cost recovery proposals were not greeted with similar favor.
The company had requested the revenue decoupling mechanism (RDM), alleging that ongoing conservation and energy-efficiency initiatives were exerting downward pressure on the utility’s sales, and hence its revenues. To assure that successful usage reduction campaigns would not adversely affect actual revenues even if the company experiences lower sales, Consumers Energy suggested tracking its sales and revenues separately through the RDM. It proposed modeling the decoupling program on the RDM that had already been approved for its electric operations, which was premised on a consumption-per-customer algorithm. Although agreeing that a gas RDM was appropriate, the commission noted that electric and natural gas consumption can have very different characteristics, especially during Michigan’s sometimes harsh winters. The commission therefore ruled that the gas RDM should be based on a straight revenue algorithm rather than a consumption-per-customer algorithm and also should employ a 15-year weather-normalized sales approach. To not incorporate normalization would risk extreme billing volatility for customers if the state had a colder-than-normal winter, the commission said.
Turning to Consumers Energy’s other proposals, the commission denied the utility’s uncollectible expense tracker mechanism (UETM), its pension expense mechanism (PEM), and its other post-employment benefits (OPEB) mechanism. The company had asserted that the UETM, PEM, and OPEB tracker all followed costs that are closely linked with market performance and the economy in general. Citing the fact that Michigan’s economy is in even worse shape than the rest of the country, the utility argued that the separate cost recovery mechanisms were imperative. The commission, however, observed that newly streamlined rate case procedures would prevent much of the regulatory lag that had inhibited timely recovery of such costs in the past.
Given signs that the economy was finally improving as well as its new expedited rate case schedules, the commission deemed the UETM, PEM, and OPEB mechanism unnecessary. -Subscribe to Utility Regulatory News for the full story.
