Construction of New Zealand’s first large-scale grid battery storage system is now complete, with Meridian Energy’s Ruakākā Battery Energy Storage System (BESS) being officially opened in a ceremony later today.
The 100 MW storage system, to be operated by Meridian Energy, is designed to improve the stability of New Zealand’s national grid as intermittent renewable power generation increases in the country.
Meridian Energy is building New Zealand’s first large-scale grid-connected battery energy storage system (BESS) at Ruakākā on North Island Paris, January 10, 2023 – Saft, a subsidiary of TotalEnergies, has been awarded a major contract by Meridian Energy to construct New Zealand’s first large-scale grid-connected BESS.
New Zealand’s first utility-scale battery energy storage system has commenced operation with electricity distribution company WEL Networks confirming that its 35 MW/35 MWh Rotohiko battery facility has completed testing and commissioning.
Located at Ruakākā in the country’s North Island, the 100-megawatt (MW) BESS will improve the stability of the national grid, as intermittent renewable power generation increases in New Zealand. The BESS is the first stage of a project that will include the construction of a co-located 130 MW solar farm by Meridian Energy.
Additionally, these batteries, alongside more renewable generation, will help off-set the retirement of thermal generation and support New Zealand’s transition to a low-emissions economy. The first grid-scale battery was commissioned in 2023 by Hamilton lines company WEL Networks.
