Technical FAQs 4
What is the Kapolei energy storage project?
The Kapolei Energy Storage project is a utility-scale battery farm with a storage capacity of 565 megawatt-hours of electricity, making it the largest storage project in Hawaiʻi. It officially went online before the holidays after several delays.
Does Oahu have a battery energy storage system?
A 185 MW/565 MWh battery energy storage system (BESS) recently started operating in Oahu, Hawaii, providing balancing services to support the island’s growing share of solar generation.
What is the largest energy storage project in San Fransisco?
The Kapolei Energy Storage facility in Hawaiʻi is the largest storage project in the state, with a storage capacity of 565 megawatt-hours of electricity. It is under construction in 2022. The project's developer, San Fransisco-based Plus Power, believes it is the first time a battery has been used by a major utility to balance the grid.
Will a storage battery help Hawaiian Electric deal with over-generation?
A storage battery project has not yet proven its effectiveness at scale, according to Bob Rudd, the chief commercial officer at Plus Power. The battery's capacity will help address the issue of clean energy curtailment, also known as over-generation, for Hawaiian Electric, Rudd said.
