From State Funds Pumped-Hydro Storage Projects in Lake and Sonoma Counties

How could the pumped-hydroelectric storage systems affect the California Department of Forestry and Fire Protection?

Possible What happens if… A possibility worth considering, not a forecast.

New pumped-hydro projects may provide critical emergency water and power for fire response. The development of pumped-hydroelectric storage systems, such as the one proposed at Hidden Valley Lake, could provide the California Department of Forestry and Fire Protection with critical resources during wildfire events. The system is designed to maintain a dedicated emergency fire reserve of 5 million gallons in its upper tank, which could supply firefighting operations without relying on the electricity-generating turbines. Furthermore, the microgrid component could provide backup electricity to communities during extended outages, helping maintain operational capacity for emergency services.

The facts so far

As reported. Each one links to where it comes from.

  • The proposed Hidden Valley Lake project would keep 5 million gallons in its upper tank as an emergency fire reserve.pressdemocrat.com
  • The proposed 20-megawatt Hidden Valley Lake system’s 80 megawatt-hours of stored energy could provide about four hours of generation at full capacity.pressdemocrat.com
  • The microgrid could potentially power thousands of homes through the Middletown substation during outages.pressdemocrat.com
  • The projects are intended to provide wildfire resiliency for Lake County communities.pressdemocrat.com

Why it matters

Wildfire threats are a major concern in Lake County, and the region has experienced large public safety power shutoffs, such as the one PG&E conducted in October 2020. The development of these storage systems is part of a broader effort by Lake County officials to develop an energy strategy that accommodates various technologies while protecting residents and securing economic benefits.

These pumped-hydro proposals are part of a wider energy discussion that includes geothermal, naturally occurring hydrogen, wind, and solar. The county is actively managing potential investments in these technologies, and the feasibility studies must address geological conditions, groundwater availability, and environmental effects to determine if construction can proceed.

What we don't know yet

  • Will the feasibility studies confirm the financial viability of the pumped-hydro projects by May or June 2027?
  • Which specific communities would receive backup power from the microgrids?

What would change this answer

The feasibility studies confirm the projects are financially viable and receive full state funding.The implementation of the emergency water and power reserves for the California Department of Forestry and Fire Protection would become more certain and potentially stronger.
Environmental reviews or electrical interconnection studies uncover additional costs.The timeline for construction and the ultimate size of the emergency reserves could be delayed or reduced.
