This article dives into California’s 2024–25 distributed generation numbers, the stubborn NEM2.0 backlog, and the ongoing fight over the Net Billing Tariff (NBT/NEM3.0) policy. If you’re in Marin County—from San Rafael and Novato to Mill Valley or Sausalito—these shifts could hit close to home.
It also pokes at how new tech like virtual power plants and home batteries might shake up energy habits for Marin households and small businesses. All this happens while policy battles simmer in Sacramento and ripple outward.

What the numbers mean for Marin homeowners and installers
California’s latest install data looks a bit puffed up. Why? Many projects still wrapping up landed under the old NEM2.0 contracts, not the 2023 Net Billing Tariff (NBT/NEM3.0).
For Marin County, that means places like Corte Madera and Larkspur might not yet feel the new post-NBT math that homeowners expect. Some industry folks say the NEM2.0 backlog, plus shrinking tax credits, might jam up the works in 2026—making life trickier for local installers in San Anselmo, Fairfax, and nearby towns.
Solar firms up in the North Bay have watched the backlog drag on, from Greenbrae to Novato. Many projects are still haggling over interconnection and compensation.
Timing really matters in Marin. A strong 2024–25 shows people still want rooftop solar, but if things slow in 2026, families in Sausalito and Tiburon could face delays getting new battery storage with their PV systems. That’s not great if you’re counting on lower bills and a more reliable grid when summer heat strains everything.
Policy battles and court decisions
The California Court of Appeals recently backed the Net Billing Tariff, so the current payback setup sticks around for now. Meanwhile, the state Supreme Court split with environmental groups on which legal rules apply.
Groups like the Environmental Working Group, The Center for Biological Diversity, and Protect Our Communities Foundation aren’t done—they’re eyeing more appeals. This isn’t just about net metering anymore. It’s about how the CPUC gets challenged and who keeps an eye on them, which Marin advocates in places like San Rafael and Mill Valley are watching closely.
Some folks warn that California’s policy moves usually set the vibe for other states. The CPUC’s approach to NBT/NEM3.0 could either push or hold back other public utilities commissions across the country.
For Marin, this means keeping a close eye on how these decisions shift rooftop solar and storage incentives. The outcome could even affect how CDUs on the Bayfront in San Francisco tie into Marin’s energy scene, nudging local choices about grid resilience and distributed generation.
Emerging technologies and programs to watch
While the policy wrangling continues, a few technologies and programs already offer real-world value for Marin homeowners and small businesses:
- Virtual power plants (VPPs) and Demand Side Grid Support programs bundle rooftop solar, batteries, and demand response to meet rising needs from data centers, EVs, and electrification. They do this without building more fossil-fuel peakers. In places like Tiburon and Mill Valley, VPP pilots could help keep the lights on during heat waves or PG&E outages.
- Home batteries can now earn you some side income if you join a VPP. That’s appealing for folks in Sausalito and Corte Madera who want more energy independence.
- SB 868 balcony solar could spark new interest in PV for apartments and smaller roofs. Maybe that nudges more Marin homeowners in Larkspur and San Anselmo to go bigger on rooftop systems.
- Emergency Load Reduction Program and other CPUC programs might offer some load relief, though there are still questions about costs and how much power they’ll actually deliver anytime soon.
A Marin snapshot: how local towns are embracing solar and storage
Across Marin County, you’ll spot solar panels dotting roofs in San Rafael’s Sunrise District. Over in Novato, neighborhoods near Hamilton Field are weighing the appeal of solar plus storage, especially with all this policy uncertainty swirling around.
In beloved Sausalito, waterfront homeowners see storage as a way to tame energy costs during fire season and grid emergencies. Folks in Ross and Belvedere are getting creative—installers there are tailoring smaller solar systems and battery setups to fit those tight urban lots.
Meanwhile, families in San Anselmo and Corte Madera are looking into balcony solar and higher-efficiency panels. They’re eager to maximize incentives under these ever-shifting state rules.
Even as the NBT/NEM3.0 debate drags on in Sacramento and at the CPUC, local contractors in Fairfax and San Rafael still see plenty of interest in PV and storage. There’s a real sense that Marin’s solar future will depend on how quickly policy clears up, whether storage incentives stick around, and just how willing Bay Area homeowners are to jump into VPP-enabled energy resilience. I can’t help but wonder—will they go all in?
