Backup power in the South Bay carries a regulatory weight unmatched almost anywhere in the country. The Bay Area Air Quality Management District governs engine permitting with some of the nation's strictest emissions requirements, shaping everything from equipment selection (Tier 4 conversations arrive early) to allowable testing hours to the paperwork burden of adding capacity at an existing site. A generator contractor without recent BAAQMD experience is not a bargain at any price.
Grid reality keeps the stakes high. PG&E's Public Safety Power Shutoff era made extended-runtime planning concrete for Silicon Valley operators: fuel storage sized for multi-day events, contracted refueling logistics, and fleets maintained to actually deliver those runtimes. Meanwhile the market's retrofit character — dense sites, aging installed fleets — puts a premium on EGSA-certified service depth, factory authorization with Caterpillar, Cummins, Kohler, or MTU, seismic anchorage competence, and load-bank testing that proves NFPA 110 performance rather than assuming it.

Harder than anywhere your out-of-market colleagues work. BAAQMD emissions requirements affect equipment tier selection, testing allowances, and timelines, and the district's processes reward applicants who know them well. Budget more calendar for permitting here than in any comparable US market, and hire a contractor who has done it recently.
The PSPS era reset the default: many operators now size for 48 to 96 hours of full-load runtime with contracted refueling beyond that. The right number depends on your load, redundancy, and refueling access under regional stress — a serious contractor models scenarios rather than quoting a rule of thumb.
Monthly exercise runs under load where permitted, annual load-bank testing to NFPA 110, plus fuel sampling, battery service, and transfer-switch verification. In BAAQMD territory, testing hours are constrained by permit terms — your service contractor must schedule compliance-aware, which is one more reason local experience matters.
