Additional information

Hawaiian Electric plans to own and operate a 20 MW battery capable of storing 80 MWh of energy at a cost of $43.5 million at the West Loch Naval Annex on land leased from the U.S. Navy for the West Loch solar project. The company hopes to start construction by October 2019 with the system in service by February 2020. Because storage will be paired with the solar facility, it will be eligible for the Federal Investment Tax Credit that will save customers 30% of what the project would cost without the credit.
