A patchwork of national price caps, high uncertainty for investors and measures only addressing the symptoms and not the cause of the current energy crisis were among the possible impacts of a cap on renewable power revenues proposed by the European Commission, major industry players warned.

SolarPower Europe said it welcomed the commission putting forward common European measures to address the energy crisis, adding it understands that the revenue cap at €180 ($179.77) per megawatt hour will not apply to PV installations not earning extra profits in wholesale power markets, such as those receiving fixed feed-in tariffs (FITs), contracts for difference (CfDs), or having power purchase agreements (PPAs) in place.
