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.

Software-backed safety and service

The facility will include Wärtsilä’s 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.
