01Why battery storage in Tiburon · Belvedere · Ross is its own thing.
Marin's luxury peninsula and estate enclaves — Tiburon, Belvedere, Ross, and Sausalito together represent the county's highest-value residential properties and most demanding electrical scope. The electrical work that happens here reflects what makes the area distinct. Batteries are now part of most sensible solar systems under NEM 3.0. They also stand on their own as PSPS resilience — a battery alone, without solar, still pays back over a few years of outage avoidance and rate-shifting.
Common drivers we see for battery storage work in Tiburon · Belvedere · Ross: PSPS resilience, NEM 3.0 self-consumption strategy, existing solar retrofit, critical-load backup, time-of-use rate management. Each creates a different scope conversation — we walk every project before quoting so the number reflects the actual work.
02What working here actually looks like.
Geography matters more here than people often realize. Waterfront and hillside throughout. Salt-air exposure. Long service runs. Multiple structures per property common.
Utility grid context: PG&E service mostly overhead with some underground. Storm and wind events damage service drops. PSPS exposure during fire weather.
Permit jurisdiction for this scope: Tiburon, Belvedere, Ross, Sausalito each with strict design review and rigorous permit processes.
