Energy storage equipment in hawaii

What makes Kapolei the most advanced battery energy storage facility?

Plus Power located the project near a substation connected to three other power plants so the battery “can be AAA to jump-start those other plants,” Keefe said. The combination of all these abilities in one site — capacity, grid services, black start — leads Keefe to call Kapolei “the most advanced battery energy storage facility on the planet.”

What is Kapolei energy storage?

The Kapolei Energy Storage facility on Oahu. "This is a landmark milestone in the transition to clean energy," said Brandon Keefe, Plus Power's Executive Chairman. "It's the first time a battery has been used by a major utility to balance the grid: providing fast frequency response, synthetic inertia, and black start.

What percentage of Oahu's battery capacity is Kapolei?

Kapolei alone constitutes about 17% of Oahu’s peak capacity. Hawaiian Electric needed it to take on more responsibility than batteries elsewhere have ever had to.

Why did Oahu use a coal generator?

The old coal generator provided three key values to Oahu, Keefe explained: energy (the bulk volume of electricity), capacity (the instantaneous delivery of power on command), and grid services (stabilizing functions for the grid, wonky but vital to keeping the lights on).

Why do we need energy storage technology?

"Energy storage technology that responds quickly to constantly changing conditions is an essential tool for us to use to manage the grid and operate it as efficiently as possible."
