What Capital Energy does

Capital Energy is a privately held Spanish renewable energy company founded in 2002 and headquartered in Pozuelo de Alarcón (Madrid) that operates as a vertically integrated 100% renewable electricity company across the Iberian Peninsula. Its core platform spans project promotion and development, construction, generation and operations, energy storage, green hydrogen, and retail commercialization through the Capital Energy Comercializadora subsidiary. The company develops utility-scale wind farms and photovoltaic plants with a pipeline of approximately 30-38 GW, eight named operating wind projects (La Herrada, Las Mareas, Canales Sur, El Castillar, Joluga, Maragouto, Banzas, Loma de los Pinos) and pursues a 200 MW hydrogen electrolyser in Baltanás plus three AaaS-awarded green hydrogen projects totaling 250 MW.

The business model combines long-term Power Purchase Agreements with industrial and utility offtakers (Statkraft fifth PPA, Alcoa pre-agreement from 2024), subscription-based retail electricity supply to homes and businesses, turnkey self-consumption solar installations for residential and commercial customers (Autoconsumo), and emerging hydrogen, ammonia, and storage revenue streams. Distribution is multi-channel: 16 offices across 44 Spanish provinces and 11 Portuguese districts, B2B enterprise sales teams, a direct-to-consumer retail arm, and a EUR 20 million corporate venturing vehicle (Capital Energy Quantum) executing EnergyTech pilots. Capital intensity is high, with a stated EUR 10+ billion investment plan to deliver approximately 13 GW of operational renewable capacity by 2025, financed through project-level capital, government subsidies (EUR 439.4 million in green hydrogen awards), and partnerships including Nordex (turbines), Verbund Green Power Iberia (Loma de los Pinos joint development), BlueFloat Energy (offshore wind), Lhyfe (offshore hydrogen), GE Renewable Energy, and Google Cloud (digitalization).
