Wartsila providing 2 GWh of energy storage systems to Clearway

Finnish technology group Wartsila Corp (HEL:WRT1V) on Monday said it is providing 500 MW/2 GWh of energy storage systems to US renewables developer Clearway Energy Group across five sites in Hawaii and California, which make up one of the world’s largest solar-plus-storage project portfolios.

Wartsila started booking the contracts in the first quarter of 2021, with the latest order as part of this portfolio received this month.

The portfolio covers the Daggett 2 and Daggett 3 projects, totalling 482 MW of solar and 275 MW/1.1 GWh of energy storage, in California. Construction of these energy storage systems has started and completion is expected in 2023, Wartsila said.

Clearway Energy Group is also adding 75 MW/300 MWh of energy storage to its Mililani I Solar and Waiawa solar power facilities on the island of Oahu in Hawaii. The construction of these projects is set to be completed this year.

The latest order is for a 147-MW/588-MWh energy storage system that will be coupled with the operating 192-MW Rosamond Central solar farm in Kern County, California. This system is expected to be ready in December 2023.

For all projects, Wartsila is providing its GridSolv Quantum fully integrated, modular energy storage system and its energy management platform for power system optimisation. All orders also include long-term service agreements.
