FERC Proposes New Treatment of Fuel Cells Under PURPA

Comments for FERC’s Notice of Proposed Rulemaking on Fuel Cell Energy Output (“NOPR”) were due November 25, 2020.[1]  In the NOPR, FERC proposes to modify its regulations for qualifying facility (“QF”) status under the Public Utility Regulatory Policies Act of 1978, as amended, (“PURPA”) to allow Solid Oxide Fuel Cell systems with integrated natural gas reformation equipment to be eligible for PURPA QF status.  This post provides an overview of the NOPR itself.  The Bracewell team will follow up next week with an overview of the comments that are posted in this docket. 

QF owners enjoy three primary benefits, among a variety of others.  First, the energy output of a QF may be “put” to the interconnected utility at the utility’s avoided cost unless the utility has been relieved of its PURPA purchase obligation.  With certain limited exceptions, utilities have not been relieved of that obligation for small QFs.  Second, the owners of QFs are subject to very light-handed regulation by FERC and are exempt from most FERC regulation even if they sell electricity at wholesale.  Third, many states lightly regulate the owners of QFs so QF status can relieve its owner of regulation at the state level.  As an aside, FERC’s rules implementing PURPA also apply in ERCOT, unlike many other FERC requirements.     

There are two types of QFs – small power production facilities that rely on renewable energy input such as solar, wind or hydro.  The second type of QFs are cogeneration facilities.  Cogeneration facilities are very efficient and are required to satisfy stringent PURPA operating and efficiency standards.  Most typically, a FERC cogeneration QF has an on-site thermal host that relies on its steam output for an industrial purpose (i.e., the steam is useful thermal energy).
