From the article: Tesla's Megapack battery system is stepping in to fulfill the state’s power requirements, following the end of a 30-year deal on September 1 between Hawaiian Electric and AES Corporation to provide coal power (via Hawaiian Electric).

As an alternative to the energy gap left behind by the coal power plant, Plus Power LLC is using Tesla Megapacks to build a large battery energy storage system (BESS) in the state of Hawaii.

This sustainable energy project is named Kapolei Energy Storage (KES). KES is one of the world’s largest battery energy storage systems, featuring a capacity of 565 MWh. It will be charged using a 156 MW solar energy farm.

State-owned Hawaiian Electric estimates the completion of the KES project in the first half of 2023. According to the state’s electricity supply company, 9 BESS projects are scheduled to go live by 2024 on the island of Oahu alone (FAQ PDF by Hawaiian Electric).

“Last coal shipment arrived in Hawaii at the same time as Tesla Megapack batteries that will enable 24/7 sustainable energy,” Tesla CEO Elon Musk said in a recent tweet.
