REV Renewables LeConte

125 MW / 250 MWh
Stabilising the grid in sunny Southern California

Meeting California’s decarbonisation and energy storage goals

Ensuring a more sustainable and reliable electric grid

Energy storage has become increasingly important to stabilise California’s electric grid, so much so that the California Public Utilities Commission (CPUC) approved plans in 2022 to add 15GW of new energy storage & demand resources by 2032.

With the integration of Wärtsilä’s energy storage system in Calexico, REV Renewables will provide resource adequacy obligations for utilities in the region and support various ancillary efforts for the California Independent System Operator (CAISO). The facility will reduce congestion on transmission lines moving between California and Mexico, enabling regional energy providers to add more flexible energy generation.

125 MW / 250 MWh energy storage system to REV Renewables

Battery energy storage is a key component to maintaining reliability and stability of California’s electricity grid. Wärtsilä worked with us to manage supply chain challenges, to collaborate with local communities and to perform site safety and training to bring this complex energy storage project online

Software-backed safety and service

Integrated solutions built for the long haul

The facility will include Wärtsilä’s GridSolv Quantum, a fully integrated modular and compact energy storage system, as well as the GEMS Digital Energy Platform, Wärtsilä’s sophisticated energy management system. Wärtsilä’s GEMS will be a critical safety feature providing continuous monitoring to pinpoint and isolate any system malfunctions automatically.

It will be maintained and optimised with Wärtsilä’s Service+ solution, a suite of comprehensive lifecycle solutions including scheduled maintenance services and extended warranties.
