California utility regulators final week rejected a house photo voltaic firm’s utility to type “micro-utilities” within the state, which might have allowed it to energy small, newly-built communities with photo voltaic and vitality storage and ship electrical energy with new energy traces.
The choice is a win for California’s giant electrical utilities, whose conventional monopoly is challenged by corporations and nonprofits providing prospects new methods to purchase electrical energy. Group alternative aggregators, native nonprofit entities that purchase electrical energy and ship it by utility traces, have peeled greater than 11 million prospects away from California utilities over the previous 20 years.
The state can also be residence to greater than 1.6 million houses with rooftop photo voltaic panels. Whereas rooftop photo voltaic initiatives and electrical energy offered by group alternative aggregators each nonetheless require prospects to make on a regular basis use of the electrical grid, the micro-utility idea would have allowed Texas-based Sunnova Power to construct group microgrids that may produce and transmit electrical energy with out the help of the bigger electrical energy grid (though the communities served may nonetheless hook up with it).
“It may present one other alternative, a aggressive alternative out there for sustainable vitality throughout the state, and that’s a significant precedence,” stated Adam Miller, Sunnova’s vp of microgrids, in February. A state regulatory decide advisable rejecting the proposal that month, a preliminary determination that also required a vote from the state’s public utilities fee.
After the ultimate utility determination final week, Meghan Nutting, the corporate’s govt vp of presidency and regulatory affairs, stated in an emailed assertion that the rejection “is a missed alternative to advance [California’s] aggressive housing and clear vitality objectives at a time when the state is in disaster.”
California has a statewide aim to construct 2.5 million new housing models by 2030 and to achieve carbon neutrality by 2045.
Some photo voltaic advocates fear that current state coverage choices may imperil progress on that latter goal, in addition to their enterprise. The micro-utility ruling comes simply over every week earlier than new guidelines go into impact on the incentives paid to householders for the photo voltaic electrical energy they generate on their rooftops, slicing credit by about 75 % for brand new residence photo voltaic prospects. The change is anticipated to trigger a downturn within the near-term progress of residence photo voltaic installations in California, with installations forecast to drop 38 % from 2023 to 2024, in line with vitality consulting firm Wooden Mackenzie.
Sunnova’s plan would have constructed rooftop photo voltaic and particular person vitality storage for brand new communities of 500 to 2,000 houses. In California, constructing guidelines already require that the majority new houses embody photo voltaic on their roofs. Sunnova’s proposal would add a group photo voltaic system, battery storage and backup turbines for emergencies. Photo voltaic electrical energy could be shared throughout the group in addition to saved for later use. Sunnova aimed to supply electrical energy at prices decrease than utility charges.
Regulators on the California Public Utilities Fee (PUC), which assessed the appliance, stated Sunnova didn’t present sufficient details about the main points of its proposal. A petition to dismiss the appliance from the PUC’s public advocate additionally argued that the Sunnova subsidiary that submitted the appliance doesn’t meet the state’s definition of a micro-utility.
David Cheng, a workers legal professional on the Utility Reform Community, a client advocate group, expressed concern that Sunnova was making use of for “blanket approval” to construct microgrids all through the state with out offering particulars on their particular person configuration. Cheng stated the group was additionally involved about some unfavourable client experiences with the subsidiary’s dad or mum firm.
“To ensure that the general public curiosity to be correctly protected, these utilities should be correctly regulated. They should have governance, they should have oversight,” stated Cheng. “Sunnova’s proposal may be very problematic … It desires to primarily create a brand new utility with we don’t know what sort of oversight and blanket authorizations from the fee. That, to us, will not be within the public curiosity.”

Nutting at Sunnova stated in emailed responses to questions from Inside Local weather Information that the corporate was not trying “to personal and function microgrids exempt from regulation and oversight.”
Supporters of the proposal included photo voltaic advocates and a few environmental teams. Some organizations that backed the appliance have additionally urged utility regulators to rethink parts of the house photo voltaic compensation guidelines that go into impact April 15.
The Heart for Organic Variety, a nationwide environmental group, argued in a regulatory submitting with different local weather and clear vitality advocacy teams that Sunnova’s utility “needs to be inspired to advertise decarbonization, resiliency, grid reliability, buyer alternative, and vitality fairness because the state appears to be like to modernize the electrical grid for the twenty first century.” The group additionally joined with the Environmental Working Group and the Defend Our Communities Basis to file a proper request asking regulators to rethink their determination on compensation charges for Californians putting in rooftop photo voltaic. The fee hasn’t formally responded.
“Commissioners needs to be making certain that everybody can profit from native clean-energy technology, not placing up pointless roadblocks,” stated Roger Lin, an legal professional on the Heart for Organic Variety, in a March press launch.
Along with ruling on Sunnova’s utility final week, California utility regulators unveiled guidelines for a $200 million program designed to incentivize utility-led microgrid initiatives in tribal communities and communities the state identifies as deprived or weak that will expertise energy outages.
In its utility, Sunnova famous that its microgrids may present backup energy to the communities they serve throughout excessive climate or throughout energy shutoffs, which California utilities perform throughout occasions of excessive fireplace threat to maintain gear from igniting wildfires. Energy outages throughout climate occasions and disasters have impacted prospects throughout the U.S.
After the appliance was dismissed, Sunnova stated it was evaluating the potential to implement the micro-utility mannequin in different states—Miller stated it might be a chance in roughly 15 others—along with contemplating a possible enchantment in California.
“We’re evaluating all choices,” Nutting stated in an electronic mail. “As we transfer ahead from right here, we’ll proceed to work tirelessly on future functions to advocate for client alternative and to push for a extra aggressive vitality market that prioritizes the wants of the folks over the pursuits of monopolistic utilities.”
