FAQ — Generator Installation in San Jose
How much does a 22 kW generator cost in San Jose?
A 22 kW generator costs $13,500-$22,000 installed in San Jose. Close to the California average. Silicon Valley labor rates are offset by strong installer competition in the South Bay market.
Am I served by PG&E or SVP?
Downtown San Jose and some central neighborhoods are served by Silicon Valley Power (SVP), a municipal utility. Most of the South Bay, including Campbell, Los Gatos, Saratoga, and Cupertino, is PG&E territory. Check your electric bill.
