With MACSE it looks to stability instead of merchant upside David Battista (Pexapark)
The first MACSE auction, held in late September 2025, allocated the full 10 GWh of capacity on offer in Central, Southern and island bidding zones, under 15-year, fixed-price tolling agreements. The auction functioned on a pay-as-bid basis, with final awarded prices averaging just below 13 kEUR/MWh/year, according to TSO Terna, almost three times lower than the ceiling price of 37 kEUR/MWh/year. Average capacity of awarded projects was 125 MW and duration averaged at 6.7 hours, with all awarded assets being above 6 hours.
