Hawaiian Electric Industries Inc. has announced plans to begin construction in January of Maui’s first large standalone load-shifting battery energy storage system $(BESS)$. The Waena BESS, a 40 MW/160 MWh facility, will be located in Central Maui and is designed to enable the retirement of four generating units at the Kahului Power Plant. Approved by the Public Utilities Commission in December 2023, the project will support Hawaiian Electric’s transition to renewable energy, with the goal of generating 100% of electricity from renewables by 2045. The Waena BESS, expected to be operational by 2027, will store and dispatch renewable energy from sources such as solar and wind, helping to reduce carbon emissions and increase grid reliability.
