“For the first time a federal court has said utilities can be liable under antitrust laws if they attack rooftop solar,” said one advocate. “The future for renewable energy just got a lot brighter.”
Clean energy advocates celebrated Monday after a federal appeals court reversed a lower court’s decision and ruled that Arizona power utility Salt River Project—which jacked up electricity rates by more than 60% for customers who installed rooftop solar in the Phoenix metropolitan area—can be prosecuted for violating federal antitrust laws.
“We’re thrilled that the Salt River Project will be held accountable for obstructing rooftop solar,” Jean Su, director of the Center for Biological Diversity’s energy justice program, said in a statement. “This is a game-changer in the struggle to defend rooftop solar against utilities’ all-out war on clean, affordable, climate-resilient energy.”

This spring, Alameda County approved of the Aramis Renewable Energy Project, dividing East Bay environmentalists who disagree about whether the undeveloped North Livermore Valley should remain open ranchland and wildlife habitat, or whether part of the flat, sunny valley would be put to better use as a solar farm to help the Bay Area transition away from fossil fuels.
All around California, the development of open space to produce renewable energy has put climate and biodiversity goals at odds. To meet the state’s 2045 goal of 100 percent renewable energy will require between 1.6 and 3.1 million acres of wind and solar, according to projections from The Nature Conservancy, and much of that land, like the North Livermore Valley, has wildlife living on it. The debate has become acrimonious, framed as a choice between stopping the extinction of the desert tortoise or the extreme heat killing people in the Pacific Northwest.
But some scientists and activists say there’s another way: the deployment of distributed solar systems, such as those on rooftops and over parking lots. After federally threatened desert tortoises died as a result of the Yellow Pine Solar Project in the Mojave Desert, Kevin Emmerich, co-founder of Basin and Range Watch, wrote, “Does using renewable energy mean we have to push species toward extinction? No, these solar panels can easily go on rooftops and brownfields.” Already over a million homes in California have rooftop panels, and more residential rooftop solar is installed here each year than any other state by far.

The California Public Utilities Commission (CPUC) voted unanimously to approve major modifications to the “Avoided Cost Calculator” (ACC) that deeply undercuts the value of rooftop solar on Thursday. The vote came after over 7,000 public comments were submitted to the commissioners protesting the modifications and after dozens of members of the public called to testify at the commission meeting.
The ACC is a model developed by E3, a consulting firm regularly used by utilities to put out research products biased against distributed energy generation, that is also under contract with the CPUC. The ACC measures utility avoided costs from customer solar — how much utility costs go down for every solar roof built in California. It is the state’s official “value of solar” calculator.
This year E3 and CPUC included major revisions that cut the value of rooftop solar in the 2021 calculator by about one-third the value in the 2020 version. The calculator has an additional 30 GW of utility-scale solar and storage going online by 2025.
“Rooftop solar is essentially crowded out by these new resources and its value is measured to be lower,” industry advocacy group Save California Solar stated in a press release. “The idea of 30 GW of utility-scale solar and storage being installed over the next four years is wildly out of step with reality.”

A New Roadmap for the Lowest Cost Grid
Energy nerds love arguing over the value of distributed energy resources (DERs), the rooftop solar panels and customer-owned batteries that are growing more popular by the day. There’s a fight in California right now over the value of energy from rooftop solar, just the latest skirmish in a long war that has ranged over numerous states.
The conventional wisdom in wonk circles is that the value provided by DERs is not sufficient to overcome the fact that the energy they produce is, on a per-kWh basis, much more expensive than that produced by utility-scale solar, wind, and batteries (residential solar is roughly 2.5 times as expensive as utility-scale solar, according to NREL).
For that reason, many wonks view DERs as a kind of boutique energy and argue that public funds are better spent on utility-scale energy.
Turns out: no, that’s wrong. Some groundbreaking new modeling demonstrates that the value of DERs to the overall electricity system is far greater than has typically been appreciated.
