Ingeteam has commissioned the Hale Kuawehi solar-plus-storage project in the city of Waimea on Hawaii.

The Basque electrical energy conversion company supplied 11 integrated power stations which connect to solar panels and batteries as an all-in-one solution for a project developed by Canada’s Innergex Renewable Energy Inc.

The site comprises a 30 MW photovoltaic plant and a 30 MW/120 MWh battery storage system. The electricity produced will be purchased over 25 years by the Hawaii Electric Light Company (HELCO) under a power purchase agreement.

The Hawaiian archipelago has set a goal of meeting all electricity demand from renewable energy by 2045. Fossil fuels currently represent the primary source of electricity on the island of Hawaii, accounting for 41.3% of supply last year.

Solar-plus-storage dominating future U.S. power grid A report from Berkeley Lab reveals a significant expansion of solar-plus-storage facilities in the U.S. power plant market, highlighting an evolution from frequency to arbitrage and curtailment mitigation markets. The best is yet to come, as ongoing price decreases are still being absorbed by the market and are already being used to fill the interconnection queues with terrawatts of capacity.

Opinion & Analysis

When will there be nationwide financing solutions for battery storage systems in Germany? The use of battery storage systems is essential for the success of the energy transition and the best possible use of renewable energies, but also for being able to temporarily store surplus energy from other sources. Technically, there are already solutions for all possible sizes of battery storage systems, from private home storage systems to large-scale storage systems with a capacity of more than 50 MWh. But what about the financing of battery storage systems, is it already offered as standard?
