- The towns of Angwin, Calistoga, Placerville, and Grass Valley are part of PG&E’s effort to build a network of “resilience zones” and temporary microgrids in portions of its service territory that are especially vulnerable to fire-related outages. PG&E deployed 23 MW of temporary generation from fossil fuel power (diesel) in the four towns powering fire stations, medical centers, and business districts.
- PG&E is looking for projects that can deploy between 4 MW and 69.9 MW for four or five consecutive days without any load drop and be able to meet peak and minimum customer demand throughout that period. Some feel that 100% renewables plus storage is not tenable with these requirements
- “We think you could do clean energy — it’s a mix of generation, batteries and demand response,” Sierra Club’s Amezcua said, adding that PG&E’s plans for its resilience zones needs to be consistent with the state’s air quality and greenhouse gas emission reduction goals.
