Apr 28, 2026 - Solar Saturation & Grid Collapse: Spain`s BESS Opportunity Spain has approximately 42GW of utility-scale solar and 50GW when rooftop is included, yet less than 100MW of grid-connected battery storage. In February, solar capture rates hit €1.30 per megawatt hour, a fraction of the €30–35/MWh needed for a solar project to break even. So why hasn`t battery storage followed the solar boom and could it be the key to rescuing solar revenues? Pablo Martinez Serrano, Iberia Industry Lead at Modo Energy, joins Ed Porter to break down why Spain`s energy market defies easy assumptions, and what the Iberian blackout changed. They cover: Why Spain`s hydro fleet masked the need for batteries for years, and why that`s no longer enough as solar saturation bites. Why solar developers are earning less and less for every unit of power they generate and what that means for the projects still in the pipeline. The co-location thesis: why existing solar asset owners are turning to BESS to fix their generation profile and unlock ancillary service revenue What actually caused the Iberian blackout: voltage instability, cascading disconnections, and why the TSO had already flagged the risk Spain`s new voltage control market: how it works, why priority of dispatch may be more valuable than the reactive service payment itself Similar news:
