The overproduction of electricity from RES reached 4 gigawatts at Easter: The special plan to manage the imbalance

A surplus of 3-4 gigawatts of powerfulness procreation occurred implicit the Easter holidays, owed to accrued accumulation from renewable vigor sources and reduced daytime demand. This imbalance creates important problems successful the grid which were nevertheless addressed done the coordination of the applicable stakeholders and manipulations (cut-offs of Renewable Energy Sources units, exports, activation of pumping) that prevented the anticipation of powerfulness cuts.

These moves were decided astatine the gathering nether the Minister of Environment and Energy, Stavros Papastavrou and the Deputy Minister, Nikos Tsafos who met with ADMIE, DEDDIE and the Regulatory Authority, held connected Good Wednesday.

In particular:

-The ADMIE proceeded to chopped disconnected the accumulation of renewable vigor plants connected to the precocious voltage, exports and activation of the pumping units of hydroelectric powerfulness plants successful the system.

-For DEDDEOthe captious parameter was the improvement of the quality to telecontrol the RES plants connected to its network, which was not disposable past year. By mode of illustration, astatine Easter 2025, the TSO had the quality to telecontrol lone 1,638 RES plants with a full capableness of 2,286 MW, portion for much than 5,600 generators with a full capableness of astir 3.5 GW, the implementation of the restrictions depended connected their effect to messages (SMS, emails) from the Operator. By Easter 2026, contempt the information that astir 550 MW of further RES were added and the full installed capableness had risen to 9,000 MW, the TSO tin present centrally power 6,200 plants with a full capableness of 5.4 GW.

-At the aforesaid time, it was observed that galore renewable vigor producers, represented successful the vigor markets by the Accumulative Representation Entities (ACEs), went connected to voluntarily halt injecting vigor for definite hours from their parks, owed to the antagonistic oregon zero vigor prices that existed during these periods successful the pre-day marketplace of the Energy Exchange.

Finally, these days, for the archetypal time, 2 energy retention stations (batteries) of tiny – comparative to the size of the marketplace – capableness were successfully operated for the archetypal time, which nevertheless besides contributed to solving the problem.

According to sources astatine SYPEN:

“With the instauration of 2 caller Control Centres, successful conscionable 1 year, the PPC has moved from an situation of constricted tele-management and piecemeal involution to a authorities of extended distant monitoring, nonstop tele-management and the implementation of targeted, real-time proportional cuts

In summation to the technological and operational maturation of the power infrastructure of the BPA, a broader competitory situation successful the cognition of the marketplace is present being shaped done organization interventions, which contributes to limiting the request for operators to marque cuts.

This transition, combined with the maturing of the marketplace and the shielding of the organization model that enhances competition, ensures the uninterrupted cognition of the energy strategy for the payment of Greek consumers.”
