Portugal’s floating solar energy auction sets world record negative price

Portugal’s floating solar auction just made history with a negative price: one winning bidder agreed to pay the grid 4.13 euros per megawatt hour for the right to generate clean electricity over 15 years. EDP Renováveis pulled this off by bundling 70 megawatts of floating panels on Western Europe’s largest artificial lake with wind power and battery storage, letting the profitable pieces carry the solar contract. The environment ministry estimates the auction will deliver 114 million euros in savings for Portuguese electricity consumers. It’s a striking signal of how far renewable economics have come — and a glimpse of what’s possible when countries get creative about stitching clean energy technologies together.
