County considers new solar, battery project standards

Santa Barbara County is one step away from adopting new standards governing solar and battery energy storage projects, a policy shift with real stakes for the Santa Maria Valley, where much of the county's prime agricultural land — and much of the pressure to build large-scale renewable energy — is concentrated.

The policy package passed its first reading before the Board of Supervisors on a 4-1 vote at the board's Sept. 1 meeting, according to the Santa Maria Sun. A second and final reading is scheduled for Sept. 22. If adopted, the amendments would bring multiple county ordinances into line with a new set of requirements for solar installations and battery energy storage systems, known as BESS.

What the new standards would do

The rules apply to solar and battery storage projects that encompass half an acre or more. Among the key requirements is a 50-foot setback between proposed projects and existing "sensitive receptors" — a category that includes school campuses and residential neighborhoods.

County planners say the amendments are also meant to clear up confusion about how the rules apply to the small end of the spectrum. At the Sept. 1 meeting, Planning and Development Deputy Director Alex Tuttle explained that staff added clarifying language distinguishing large industrial battery facilities from the kind of small battery packs homeowners and small businesses increasingly install.

"One thing through this cleanup we wanted to clarify is the notion of what happens when [someone says], 'Oh, it's just my Tesla battery pack on my garage wall,' or a small battery supporting a coffee shop or something like that," Tuttle said, according to the Sun. The sensitive-receptor requirement, he said, "really would not kick in until you get into those potentially larger systems that you don't typically see with single-family dwellings or for small commercial support."

For Santa Maria residents, that means garage wall chargers and small backup batteries won't trigger the same review as utility-scale facilities — but commercial-scale projects proposed near homes or schools would face new siting requirements.

A 16,000-acre cap — and a North County objection

The most contentious piece of the package is a countywide cap of 16,000 acres for large-scale solar projects, defined as projects covering more than half an acre.

Fourth District Supervisor Bob Nelson — whose district includes Santa Maria — cast the lone dissenting vote. Nelson said he would prefer a lower cap, and one split between North County and South County rather than applied countywide, according to the Sun's report.

"I think we're going to get 'solar-ed' over," Nelson said, expressing concern that agricultural land in the North County will be targeted for far more projects than land in the South County. "I would prefer the guardrail sooner, but I understand where the board majority is on this. So, we'll keep moving along."

The concern reflects a long-running tension in Santa Barbara County politics: the North County's flat, sunny farmland is attractive to solar developers, but it's also the backbone of a regional ag economy anchored in the Santa Maria Valley — strawberries, vegetables and wine grapes that depend on prime soils.

Ag industry pushes for a tighter limit

That concern was echoed during public comment. Claire Wineman, president of the Grower-Shipper Association of Santa Barbara and San Luis Obispo Counties, asked the board to adopt a countywide cap of 8,000 acres — half what supervisors proposed — arguing it would support the county's energy goals "without a disproportionate impact to agricultural resources in the communities they support, especially in the Santa Maria and Lompoc valleys," the Sun reported.

Wineman said her organization would be "open to revisiting an increase in the cap in the future if warranted." She also noted the California Farm Bureau has historically opposed some solar projects and legislation because of impacts to prime farmland.

The industry's position puts a concrete number on a debate that has played out across the Central Coast as California pushes to expand renewable energy generation and storage: where large projects should go, and how much farmland — if any — should be converted to energy production.

What's next

The Board of Supervisors is scheduled to take up the policy package for its second and final reading on Sept. 22. If approved on second reading, the ordinance amendments would take effect following the standard process for county code changes.

Key questions likely to linger for Santa Maria-area residents and growers:

• How quickly the 16,000-acre cap fills. Nelson and ag industry representatives worry the cap could disproportionately draw projects to North County land before anyone revisits the limit.
• How setbacks play out in practice. A 50-foot buffer from homes and schools is modest by some jurisdictions' standards, and its enforcement will fall to county Planning and Development staff.
• Whether the cap is revisited. Wineman's suggestion that an 8,000-acre cap could be raised later "if warranted" signals the industry isn't opposed to solar outright — it's opposed to what it sees as an unbounded commitment of farmland.

The debate also lands amid broader growth in battery storage across California, driven by the state's push for grid reliability during heat waves and wildfire-prevention power shutoffs. BESS facilities have drawn scrutiny elsewhere over fire safety concerns, which is partly why counties have moved to define setbacks and permitting pathways explicitly.

For now, the board majority has settled on 16,000 acres as the ceiling. Whether that number holds — and whether the Santa Maria Valley's share of it stays proportional — is the question Nelson says he'll keep watching.
