Background
About Niba in Spain
Niba is a 100% digital electricity retailer launched in June 2025 as a corporate start-up within the Iberdrola Group. It pairs the reliability and scale of one of Spain's largest energy companies with an app-first experience built for people who would rather not spend an afternoon decoding their electricity bill.
The lineup is deliberately small: a flat 24-hour plan for households that want one predictable price, and a three-period plan for homes that can shift usage to cheaper night and weekend hours. Both are fixed-price, which means your rate does not move with the wholesale market during the contract term.
Niba supplies mainland Spain and comes without permanencia, so you are free to leave at any time. Run your latest factura through our free check to see how Niba's rates compare with your current tariff for your actual consumption pattern.
