Hawaiian Electric Plans $150 Million Battery Storage Investment

Pacific Business News:

Hawaiian Electric Company will invest close to $150 million in two new energy storage projects on Oahu. The Honolulu-based utility on Wednesday announced plans for two gird-scale projects on the island’s west side. They include a 20 megawatt system to support the 20 MW West Loch solar system, which is currently under construction at Joint Base Pearl Harbor-Hickam’s West Loch Annex, and a 100 MW system at Hawaiian Electric’s Campbell Industrial Park generating station.

“These projects will improve resilience and reliability while helping stabilize costs for our customers,” Ron Cox, Hawaiian Electric senior vice president for operations, said in a statement. “As Hawaiian Electric progresses toward 100 percent renewable energy, these storage projects will reduce our fossil fuel use by enabling more solar and wind integration into the grid.”

At West Loch, the utility plans to own and operate a 20 MW battery capable of storing 80 megawatt-hour of energy at a cost of $43.5 million. The solar-plus-battery project is being built on land leased from the U.S. Navy. The company said it hopes to start construction by October 2019 with the system in service by February 2020. Due to the storage component, the project will be eligible for the federal Investment Tax Credit that will save customers 30 percent of the cost.

The Campbell Industrial Park project is also expected to start construction in October 2019 with the battery set to enter service by October 2020 at an estimated cost of $104 million.

The two battery storage projects will reduce the need for conventional, oil-fired generation during the evening peak and at night, reducing fossil fuel use and lowering carbon emissions, according to the utility.
