The Hawaiian hybrid project Hale Kuawehi is now operational. Ingeteam has completed the commissioning work for the eleven inverter power stations supplied for Innergex Renewable Energy Inc. The site adds a 30 MW capacity of solar PV energy to Hawaii grid combined with a 120 MWh battery storage system.
This project, located in the town of Waimea, on the island of Hawaii, will be able to supply power to some 14,600 Hawaiian homes. The batteries will charge during the day and will be able to inject the stored energy into the grid when necessary, for up to 4 hours at a time.
The electricity generated by this project will be acquired over the next 25 years by the local power company, Hawaii Electric Light Company (HECO), through a long-term power purchase agreement.
In the words of Nohra Nasr, vice president and general manager of Ingeteam’s photovoltaic and BESS businesses in the US, “it is quite rewarding for Ingeteam to contribute to Hawaii’s goal of being 100% renewable and free of fossil fuels using our technology. We appreciate the confidence of Innergex to grant us this opportunity to be a part of a more resilient and sustainable grid.”
Ingeteam’s supplied eleven fully integrated inverter power stations, which were connected to both the photovoltaic panels and the batteries. This system offers high power density and is delivered as an all-in-one solution for quick installation in the field.
Hawaii will implement short-term actions that will lead to 100% of its energy needs being met by renewable sources by 2045. Currently, on the island of Hawaii, hydrocarbons continue to be the primary source of electricity generation, with 41.3% of the total in 2024.
To date, Ingeteam has supplied or is contracted to supply the US market with 9.5 GW of photovoltaic and battery inverters, supporting the country’s transition to cleaner energy systems that are less dependent on fossil fuels.
