Trina Storage has been selected to supply technology for one of Greece’s largest battery energy storage systems (BESS), as state-owned PPC Renewables moves ahead with construction of the 50MW/200MWh Amyntaio project in Western Macedonia.
The Chinese energy storage manufacturer and system integrator — the dedicated storage arm of vertically integrated solar PV giant Trinasolar — announced the agreement on 12 November, calling the project a “cornerstone” for its future development pipeline in Southeast Europe.
PPC Renewables first confirmed the start of construction in late October but did not disclose the technology provider at that time. The company is the clean energy subsidiary of the Public Power Corporation (PPC) Group, Greece’s largest electricity utility, majority-owned by the Hellenic Republic Asset Development Fund.
Under the newly announced deal, Trina Storage will supply a turnkey AC BESS solution with a nameplate capacity of 244MWh. The system will include 60 Elementa 2 DC block battery cabinets, eight integrated power conversion system (PCS) units, and medium-voltage skid enclosures. The companies have also entered into a long-term service contract covering maintenance, remote monitoring, and spare parts, supported by 10-year performance and availability guarantees.
Unveiled at the Energy Storage Summit EU in London in February 2024, the Elementa 2 platform uses Trina Storage’s proprietary 306Ah high-energy-density lithium iron phosphate (LFP) cells. Each unit offers 4,073kWh of capacity inside a standard 20-foot ISO container, equipped with liquid cooling and four layers of safety protection — including Honeywell Li-ion Tamer gas detection and automated aerosol-based fire suppression.
Once online, the Amyntaio BESS will support grid stability through frequency regulation, facilitate renewable energy integration, and contribute to resource adequacy.
The project is being built at the site of PPC’s 600MW Amyntaio thermal power plant, a former coal-fired facility in Western Macedonia that is now undergoing transition.
