MACSE 2029: Higher premium, but new uncertainties – three lawyers weigh in ess-news.com

Italy’s energy regulator ARERA raised the maximum premium for the 2029 MACSE battery-storage auction to €27,000/MWh/year, up from the €22,000 proposed in consultation, and introduced annual updates to the technology assumptions used to set auction parameters. Lawyers Germana Cassar of DLA Piper, Marcello Astolfi of Project Lex and Cristina Martorana of Legance say unresolved risks include grid access, permitting deadlines, lithium-price volatility and uncertainty over auction volumes after 2029; Terna has identified a provisional 16 GWh requirement for 2029.
