EEG`s Energy Storage Unit at the front line of the large projects of the Just Development Transition Plan.

The creation of a cutting-edge Energy Storage Unit, with an installed power of 250 MW/1000 MWh, by the EUNICE ENERGY GROUP (EEG) in Western Macedonia (area of Ptolemaida) attests to the fact that Greece is leading the way in energy transition projects from polluting fossil fuels to clean energy.

The Battery Energy Storage System (BESS) project by the EUNICE ENERGY GROUP (EEG) in Western Macedonia is at the forefront of the 16 large projects of the Plan for Just Development Transition, whose immediate implementation was announced at an official press conference held on 9 September 2020 by the Minister for the Environment and Energy Kostis Chatzidakis, on behalf of the Greek Government.

This is a project with significant domestic added value, which provides immediate and tangible benefits to the local and national economy, both during its construction and operation. It will boost local employment with new job opportunities, contribute to the National Growth Strategy and put Greek entrepreneurship and Greek expertise on the front line of international energy developments.

The project has received an official statement of support from the Greek State through the competent Ministry of Energy and has been submitted for inclusion in the next revision of the Ten-Year Plan for the Development of European Networks (TYNDP) 2020 of ENTSO-e (already included in the preliminary list of projects). The project will then be submitted for inclusion in the European Commission’s Common Interest (PCI) 2021 Projects.

As far as Greece is concerned, an application with a complete file of studies and supporting documents of the project was submitted to Regulatory Authority for Energy (RAE)  in August 2020, in order to obtain the relevant production and storage license.

It is a purely Greek private investment of 285 million euro which has already reached the licensing stage, with the goal of becoming fully operational by 2022, while at the same time comprising a project of pan-European interest and coverage.

It gathers and fully utilizes the technical, operational and economic benefits, the deployment ease, the low environmental impact and the cost reduction of storage systems in the liberalized electricity market of the post-lignite era.

Storage units, such as the new investment of the EUNICE ENERGY GROUP (EEG) in Western Macedonia, provide the country’s Electricity System with cleaner energy, ensuring safety, flexibility and stability, while also leading to the reduction of electricity prices, for the benefit of Greek households and businesses.
