Portugal's latest solar auction made headlines earlier this month as record-low negative bids were posted, with the results illustrating the value developers place on securing a grid connection and the strong potential they see in hybridising renewables assets.
Concerns have been raised that new measures introduced by Spain’s government to limit windfall profits of renewable energy plants could dent investor confidence and impact the stability of the country’s solar sector.
As energy markets continue to adapt and grow, energy arbitrage could overtake frequency markets as a key revenue stream for many co-located solar plus storage projects.
The results of Spain’s auction this week for 3GW of renewables capacity have been widely welcomed by the country’s solar sector, but calls have been made to tweak future auctions to support smaller-scale projects as well as encourage the participation of bids with energy storage.
Questions have been raised about the need for Spain to roll out a new renewables auction mechanism to drive up PV installation rates and meet its 2030 green energy targets.
