Greece launches fast-track review for standalone battery storage bids under 4.7 GW tender

Greece is accelerating the development of standalone battery storage projects by introducing a fast-track evaluation process for bids submitted under a 4.7 GW market-based tender. The move is designed to strengthen grid flexibility while modernizing energy infrastructure, with an emphasis on getting projects ready for implementation sooner.

Committee review to speed decisions across transmission and distribution

A newly established committee has started reviewing proposals with the goal of quickly identifying projects that can proceed. The committee includes representatives from ADMIE and DEDDIE, linking decision-making across both transmission and distribution networks—an approach intended to support smoother project integration.

First phase targets about 2 GW, with June preliminary rankings

The first phase will cover approximately 2 GW of capacity. Preliminary rankings are expected by June, with around 900 MW earmarked for connection to the distribution network and about 1.1 GW intended for the transmission system, creating a split across grid levels.

How projects are screened and prioritized

The evaluation process begins by aligning submissions from the Ministry of Environment and Energy with those provided by network operators. After applications are checked against formal requirements, eligible projects move into prioritization based on the tender’s criteria.

On the distribution side, DEDDIE will assess hundreds of proposals totaling more than 2 GW. On the transmission side, ADMIE will initially review a subset of projects grouped by technical criteria, reflecting both intense competition and strong investor interest.

Next steps: connection approvals and phased rollout

Finalizing the first ranking lists in the coming weeks is expected to unlock grid connection approvals for the initial set of projects. The remaining pipeline—around 2.7 GW—will be evaluated later after additional technical parameters are defined, supporting a structured, phased expansion of battery storage capacity.
