Madeira electricity price rise unrelated to new wind turbines, regulator shows

Electricity prices for regulated-market consumers in Madeira will rise about 2.7% from 1 October, a change some readers linked to the new wind turbines being installed at Paúl da Serra. Regulator ERSE, not utility EEM, sets tariffs based on annually calculated 'allowed revenues', which for 2026 total €238.7 million, with €76.9 million offset through a national tariff convergence mechanism that spreads island supply costs. The October rise stems from a quarterly update mechanism triggered when wholesale energy purchase costs deviate by more than €10/MWh from forecasts, not from EEM investment decisions.
