Solarig Alternative Energies

What Solarig Alternative Energies does

Solarig Alternative Energies is a Spanish vertically integrated renewable energy company headquartered in Madrid that develops, builds, operates, and maintains utility-scale solar, wind, and battery energy storage assets. The company operates across 12 countries, primarily in Spain, Portugal, and Latin America, with a recently launched entry into the United States. Its asset base comprises 15+ GW under operations and maintenance and a 20 GW development pipeline, positioning it as the 4th largest photovoltaic O&M operator globally according to Wood Mackenzie.

The company operates three product lines: Renewable Electricity (PV, wind, and BESS IPP and EPC services), Green Gases through its Biorig subsidiary (biomethane and renewable hydrogen), and New Technologies focused on storage and emerging renewable solutions. Its business model combines long-term revenue from power purchase agreements and feed-in tariffs with capital-light O&M service contracts; revenue reached €275.7M in 2025, tripling from €125M in 2022, and the company achieved first net profit in 2024. Technology is anchored in a centralized monitoring platform that ingests drone inspection data and predictive maintenance algorithms across the operational fleet.

Solarig serves a mix of utility offtakers, corporate PPAs (including a tie-up with a telecom operator), and infrastructure investors. The company employs 1,500+ people globally and holds SBTi-validated emissions targets, supporting its standing in regulated EU renewable energy markets. Its growth strategy combines organic pipeline conversion, geographic expansion into the Americas, and diversification into green gases and storage to broaden the revenue base beyond pure-play solar generation.
