Clearway dedicates 39-MW solar project with battery in Hawaii
- Clearway Energy Group on Thursday inaugurated its Mililani Solar I plant, a 39-MW solar array combined with a 156-MWh battery storage space system, in Hawaii.
The USD-140-million (EUR 135m) project is the initial utility-scale solar and battery storage space power plant on Hawaii's Oahu Island. It includes in 3 solar facilities previously commissioned by the firm on the island.
Located in Mililani Agricultural Park, the new installation will certainly help boost the grid when the state is closing down its last coal plant in September, the developer noted.
Clearway has a second solar as well as storage space plant under construction in Waiawa, which will have 36 MW of solar capacity and a 144-MWh battery. Its 5 solar facilities on the island amounting to 185 MW will certainly offer Hawaiian Electric's grid.
Mililani I Solar is now supplying power to Hawaiian Electric's grid at a cost of USD 0.09 per kWh. It is the initial of 9 clean energy projects that the utility will bring online over the following 2 years on Oahu. Most will be creating power at one-third the expense of oil, it said.
Finland's Wartsila Corp (HEL: WRT1V) was the battery carrier for the project. Moss supervised of building.
