Cero Gains Approval for 72-MW Battery in Greece

May 16, 2025 11:06 AM ET
  • Cero Generation powers up Greece with a 72-MW energy storage facility, enhancing solar efficiency and sustainability without government subsidies.

Cero Generation, part of Macquarie’s Green Investment Group, has been authorized to install a 72-MW/164-MWh energy storage facility at a 100-MW solar park in Western Macedonia, Greece. The approval was granted by the Ministry of Environment's General Directorate of Environmental Policy. The battery energy storage system will be co-located with a photovoltaic farm in Melitis and Amyntaio, Florina, and will connect to the National Electricity Transmission System.

Cero also owns the 100-MW Delfini solar PV park in Drama, Greece, which became operational last autumn. This plant is notable for not using Greek government subsidies, instead relying on a private power purchase agreement.

What are the details of Cero Generation's new energy storage project in Greece?

  • The energy storage project is part of Cero Generation's strategy to enhance renewable energy integration and grid stability in Greece.
  • The 72-MW/164-MWh battery energy storage system (BESS) will help manage the intermittent nature of solar power by storing excess energy generated during peak sunlight hours and releasing it during periods of high demand or low solar generation.
  • The project is expected to support Greece's national goals for increasing renewable energy capacity and reducing carbon emissions.
  • The co-location of the BESS with the 100-MW solar park in Melitis and Amyntaio allows for efficient use of land and infrastructure, reducing overall project costs.
  • The facility will contribute to the local economy by creating jobs during the construction and operational phases.
  • Cero Generation's investment in this project underscores its commitment to expanding its renewable energy portfolio in Europe.
  • The project aligns with the European Union's broader objectives of increasing energy storage capacity to support the transition to a low-carbon energy system.
  • The integration with the National Electricity Transmission System ensures that the stored energy can be efficiently distributed across the grid, enhancing energy security and reliability.
  • Cero Generation's approach to financing, as demonstrated by the Delfini solar PV park, may involve innovative financial models that do not rely on government subsidies, potentially including private power purchase agreements or other market-based mechanisms.
