The US Court docket of Appeals for the District of Columbia Circuit dominated that solar energy facility alternating present (AC) measurement is the technical consideration essential in figuring out “Qualifying Facility” standing below PURPA. The case was filed by the Photo voltaic Power Industries Affiliation (SEIA).
The case focuses on Montana’s Broadview Photo voltaic facility, which utilized for an 80 MW (AC) Qualifying Facility electrical energy contract with the state below PURPA pointers. The power has a capability of 80 MW (AC)/160 MW (DC) of solar energy, and 50 MW/200 MWh of batteries. Broadview Photo voltaic says the location will function 20 inverters, rated at 4 MW (AC) every.
An preliminary determination from the Montana Public Utilities Fee in September 2020 said that solar energy amenities have to be primarily based on a direct present (DC) ranking, which is identical approach that photo voltaic panels are rated. Broadview Photo voltaic argues that its peak grid output, decided by its inverters, is what needs to be thought-about. The fee realized that this was a departure from the earlier logic, however they continued with it. Broadview Photo voltaic appealed.
The Montana Supreme Court docket has dominated in opposition to the fee’s obvious anti-solar biases prior to now. In March 2021, the fee vacated its first determination, as a substitute stating that the ability’s peak grid output was the motivation for the PURPA regulation.
