Wärtsilä has reached an agreement with Clearway Energy Group on a contract that will see it supply Clearway with a 500 MW/2 GWh portfolio of energy storage systems. The storage systems will be used across a series of solar and storage projects that Clearway is developing in California and Hawaii. The five-project portfolio includes 75 MWac/300 MWh located in Hawaii and 415 MW/1.7 GW in California.

- In Hawaii, Clearway is developing the Mililani I Solar and Waiawa Solar Power facilities on the Island of Oahu and represent Wärtsilä’s first large-scale energy storage systems in the state.
- The addition of energy storage will help Clearway Energy Group ensure reliable delivery of sustainable energy and contribute to Hawaii’s goal of reaching 100% renewable energy generation by 2045.
- In California, 482 MW of solar and 275 MW/1.1 GWh of energy storage are being split across the Daggett 2 and Daggett 3 projects, which are being developed in San Bernardino, California, adjacent to the site of a retired coal and natural gas plant.
- The storage systems will deliver renewable energy during increasingly volatile peak periods and help the state reach its goal of 100% carbon-free electricity by 2045.
- Each 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 energy management platform for power system optimisation.
Path to 100% Perspective
To achieve goals of both reliable and renewable energy, it is critical to think beyond solar panels and wind turbines. The addition of storage technologies is essential because both wind and solar technology is dependent on the weather. The storage system is one way to ensure there is enough power when the sun isn’t shining or the wind isn’t blowing. To take it one step further, power producers should also invest in flexible engines, capable of starting and stopping when needed to ensure a reliable energy supply.
