Hawaiian Electric withdrew plans to build a key battery storage system on Oahu; tight deadlines and supply chain issues appear to be the cause.

U.S. renewable energy deployment is dependent on an import-heavy supply chain, and the outlook for a domestic supply of components isn’t getting better.

Hawaii's PUC approved construction of the West Kauai Energy Project, a pumped storage hydropower project designed to produce 110 GWh of annual output.

Reaching the goal of 24-7 carbon-free power will require a dramatic increase in storage to fill gaps in renewable output, large energy users say.

A Hawaii PUC status conference provided hope that HECO can find a timely way to fill the void left by the closure of Oahu’s largest electricity source.

Hawaiian Electric Company is asking the PUC for $25 million for a program to encourage customers to install DER equipment in their homes.

State utility regulators once again question the feasibility of a Hawaiian Electric Co. plan to shut down a vital coal plant.

A solar plus pumped hydro storage project proposed by the Kauai Island Utility Cooperative could produce a quarter of the island’s energy requirements.

HECO says a proposed massive energy storage facility on Oahu will help fill the capacity gap left by the closure of a 180-MW AES coal-fired plant.

The shutdown of the AES Hawaii Power Plant in 2022 could leave Oahu's energy grid with a 180-MW generation deficit.
