Hawaii’s KIUC, the top-ranked US utility in 2017 for energy storage deployment per customer by SEPA (Smart Electric Power Alliance), will pay less than US$0.11 per kWh for power from a new solar-plus-storage facility.
The residential energy storage market in the US has just enjoyed one of its biggest growth spurts so far, although action is mostly centred in specific states with supportive policies and conditions.
Hawaii’s position as one of the leading US states for energy storage deployment shows no sign of weakening as Hawaiian Electric Co last week announced 120MW of new battery storage across two projects in Oahu.
Battery storage is a “necessity” for Hawaii to reach its 100% renewable energy by 2045 target, leading to electric cooperative KIUC becoming the top-ranked US utility for watts of energy storage deployed per customer in 2017.
Projects being delivered for the University of Hawaii will allow various campus buildings to eliminate 70% to 100% of fossil fuel use as the state races towards its 100% renewables by 2045 target.

Nancy Pfund is managing partner at DBL Partners, a venture capital firm which specialises in investing in companies and start-ups that offer both rewarding financial returns, and positive social impacts. There have been some serious clean tech companies in DBL’s portfolio, including a pre-IPO investment in Tesla. With this in mind, we spoke to Nancy about how to invest in energy storage wisely and heard her views on the waves of the future. Part 2 to be published tomorrow.
Whilst most of the federal incentive buzz for energy storage surrounds California’s Self-Generation Incentive Programme (SGIP), new bills from Hawaii and Maryland provide insights on how state storage incentives are moving beyond the Golden State.
