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

How could the development of pumped-hydro storage systems affect Trane Technologies?

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

Trane Technologies faces viability study for Lake County pumped-hydro projects The state funding and legislation for pumped-hydroelectric storage systems in Lake County initiated feasibility studies for Trane Technologies' FLASHES projects. These projects include two principal developments: one at Hidden Valley Lake and another near North Lakeport. Developers expect to determine by May or June 2027 whether these projects are financially viable. If deemed viable, the projects could generate revenue from electricity sales, generating capacity, and grid-support services, potentially supporting the investments without increasing customer rates.

Why it matters

The success of these pumped-hydro projects is critical for Trane Technologies, as the projects represent a major potential revenue stream. The initial preliminary budgets placed the Hidden Valley Lake facility at approximately $120 million and the combined Hartley and Lucerne development at $180 million. The viability studies must confirm that revenues from electricity sales and grid-support services can support these investments.

These projects are part of a broader effort by Lake County to manage a growing range of energy technologies, including geothermal and naturally occurring hydrogen. The development of FLASHES systems is intended to provide wildfire resiliency and dependable electricity for Lake County communities, positioning Trane Technologies at the center of a major regional energy transition.

What we don't know yet

  • What will the final life-cycle costs of the proposed installations be?
  • Which communities will ultimately receive backup power from the microgrids?

What would change this answer

The feasibility studies uncover additional costs during environmental reviews or electrical interconnection studies.The financial viability of the projects could be negatively affected, potentially delaying or canceling construction.
The county supervisors approve a larger northern microgrid service boundary reaching Lucerne.The additional distribution and interconnection costs could reduce projected net cash flow by 20% to 25%.
