State-backed PPC Renewables has appointed Trina Storage to supply its battery energy storage systems (BESS) and long-term services for the 50 MW / 200 MWh Amyntaio battery project in Western Macedonia, at the site of a former coal-fired power plan. The installation is among the largest battery energy storage systems currently contracted in Greece, and construction had started in late October according to the developer, which is owned in a split between the Hellenic Republic Asset Development Fund, a Greek-owned fund, and the Public Power Corporation (PPC), a major electricity provider in the country.

The project will be delivered on an AC turnkey basis using Trina Storage’s Elementa 2 platform. The scope includes DC battery cabinets, power conversion systems, medium-voltage skids, and a power plant controller. According to the companies, the system will use 60 Elementa 2 battery cabinets and eight integrated PCS and MV skid enclosures. While the contracted capacity is 200 MWh, the configuration will deliver a nameplate capacity of roughly 244 MWh, with each cabinet delivering 4.073 MWh capacity.

Once operational, Amyntaio is expected to provide frequency support, improve renewable integration and contribute to adequacy in a region undergoing a long transition away from lignite. A 10-year long-term service agreement covers maintenance, remote monitoring, spare parts, and performance and availability guarantees.

“Greece is rapidly emerging as a key energy storage market in Europe, driven by auctions, policy support, and the need to integrate its abundant renewable resources,” said Gabriele Buccini, Head of Trina Storage Europe, noting that Amyntaio is its first storage contract in Greece. Trina also said its European portfolio that now includes “more than 50 projects across the UK, Germany, Italy, Spain and Eastern Europe,” totaling “over 4 GWh” of contracted capacity.
