Hawaii electric energy storage project

What is Kapolei energy storage?

Plus Power has started operating its Kapolei Energy Storage (KES) facility on Oahu, Hawaii, helping the state in its transition from fossil fuels to solar and wind. The KES project adds 135 MW/540 MWh to the Hawaiian Electric grid, with an additional 50 MW/25 MWh of additional “fast frequency response” to support grid stability.

Could a large grid-scale energy storage project reduce renewables output?

A large grid-scale energy storage project in Hawaii, featuring Tesla Megapacks, could potentially minimize the curtailment of renewables output. Plus Power has started operating its Kapolei Energy Storage (KES) facility on Oahu, Hawaii, helping the state in its transition from fossil fuels to solar and wind.

How much power does Kes add to the Hawaiian electric grid?

The KES project adds 135 MW/540 MWh to the Hawaiian Electric grid, with an additional 50 MW/25 MWh of additional “fast frequency response” to support grid stability. The advanced battery has “virtual inertia” to replicate the power-smoothing function of a conventional spinning turbine.

Are batteries coming to Oahu?

This project is a postcard from the future – batteries will soon be providing these services, at scale, on the mainland.” Located on 8 acres of industrial land on the southwest side of Oahu, the project is comprised of 158 Tesla Megapack 2 XL lithium-ferro-phosphate batteries, each about the size of a shipping container.
