Eku Energy, the UK battery platform of Macquarie’s Green Investment Group (GIG), has launched the construction of its first energy storage project in Japan, a 30-MW/120-MWh system in Miyazaki Prefecture.
The ground-breaking was held last week and marked by a traditional Japanese ceremony, the company said in a LinkedIn post.
The Hirohara battery energy storage system (BESS) will be installed in Oaza Hirohara and will be run under a 20-year offtake contract with utility Tokyo Gas Co Ltd (TYO:9531). Under its terms, Eku Energy will be the site’s owner and Tokyo Gas will hold the operating rights for 20 years. All ongoing maintenance activities will be handled by Eku Energy.
The battery is due to become operational in 2026 and is expected to be able to discharge electricity to supply about 63,000 homes for four hours.
The BESS project will be realised with debt financing extended by Mitsubishi UFJ Financial Group. Japanese engineering group Kinden Corporation, Fortec Architects and Looop Inc will be Eku Energy’s partners in the construction.
