How could the development of pumped-hydro storage systems affect Pacific Gas and Electric Company?
PG&E's microgrid support could reduce operational reliance during wildfire outages. The pumped-hydroelectric storage projects, which are being developed with support from Pacific Gas and Electric Company, are designed to provide backup electricity during extended outages. The Hidden Valley Lake system, for example, could potentially power thousands of homes through the Middletown substation during outages. This capability is critical because PG&E has previously conducted large public safety power shutoffs in Lake County due to fire danger. The microgrids are intended to deliver energy and wildfire resiliency for the communities.

How it reaches Pacific Gas and Electric Company
-
State funding and legislation were signed for pumped-hydroelectric storage systems in Lake County and Sonoma. These projects are designed to generate electricity and maintain water supplies to help communities withstand wildfire threats. Trane Technologies is developing these systems with support from Pacific Gas and Electric Company.
The full event1independent outlet -
Trane Technologies is developing the pumped-hydroelectric storage systems, which are designed to generate electricity and maintain millions of gallons of water for firefighting in Lake County. This work is part of a broader effort to manage potential investments in various renewable energy sources.

Everything about Trane Technologies -
The projects are being developed by Trane Technologies with Pacific Gas and Electric Company support. Furthermore, PG&E's Microgrid Incentive Program is funding the feasibility investigations, including geotechnical core boring and groundwater assessments. The resulting microgrids are intended to provide backup electricity during extended outages. The Hidden Valley Lake system, for instance, could potentially power thousands of homes through the Middletown substation during outages, which helps mitigate the need for PG&E to rely solely on its main grid during high-risk periods.

Why it matters
The stakes for Pacific Gas and Electric Company are tied directly to public safety and grid reliability in Lake County. PG&E has previously conducted its largest public safety power shutoff since 2020 in the region due to fire danger. These new microgrids are intended to deliver energy and wildfire resiliency, which could reduce the operational burden and risk associated with managing large-scale, fire-driven outages.
This initiative is part of a much broader energy strategy for Lake County, which is looking to accommodate a growing range of technologies, including geothermal, naturally occurring hydrogen, and solar. PG&E's involvement in these projects positions it as a key partner in the county's effort to secure dependable electricity while addressing the severe threat of wildfires.
What we don't know yet
- Will the feasibility studies confirm the financial viability of the pumped-hydro projects by May or June 2027?
