Clearway orders 2 GWh of LFP energy storage from Wärtsilä for California and Hawaii projects
The technology group Wärtsilä delivers a 500 MWAC/2-GWh portfolio of energy storage systems for developer Clearway Energy Group, a clean energy developer. The contracts cover five locations in Hawaii and California.
“The US is a paragon of the global energy transition and projects like this show that large-scale decarbonisation is possible anywhere in the world. Energy storage as a flexible balancing force is an essential component for a future with 100% renewable energy. We are very proud and grateful to have been awarded these important projects,” said Håkan Agnevall, President and CEO of Wärtsilä.
“Wärtsilä shares our vision of a world powered by clean energy. We are excited to bring a portfolio of solar and storage projects at this scale online to ensure reliable and affordable clean energy for our customers,” said Craig Cornelius, CEO of Clearway Energy Group.
The portfolio includes the Daggett 2 and Daggett 3 projects, which together represent one of the largest co-located solar and storage facilities in California, with 482 MWAC of solar energy and 275 MWAC/1.1 GWh energy storage. The Daggett projects are located in San Bernardino, California, next to the site of a retired coal and natural gas plant. The AC-coupled energy storage systems will provide renewable energy during increasingly volatile peak periods. Construction on both projects has started with an expected completion date in 2023.
Two 75 MW . projectsAC/300 MWh of energy storage will be installed at Clearway Energy Group’s Mililani I Solar and Waiawa Solar Power facilities on the island of Oahu, Hawaii. Construction is expected to be completed in 2022. The projects are Wärtsilä’s first large-scale energy storage systems in Hawaii.
The fifth project in the portfolio is a 147 MWAC/588 MWh energy storage system to be connected to the operational 192 MWAC Rosamond Central solar PV plant in Kern County, California. The energy storage system will increase the effectiveness of the solar installation by performing ancillary services, primarily solar shifts, for the California Independent System Operator. Construction is expected to be completed in December 2023.
Each facility includes Wärtsilä’s GridSolv Quantum, a fully integrated, modular and compact LFP energy storage system, as well as the GEMS Digital Energy Platform, Wärtsilä’s advanced energy management platform for optimizing energy systems. All five projects will also include long-term Service+ GAP agreements with Wärtsilä, guaranteeing capacity and maintenance with performance guarantees for the lifecycle of the energy storage systems.
