What Erg does
ERG S.p.A. is an Italian publicly listed independent renewable energy operator headquartered in Genoa, operating across eight European countries and the United States. The company runs onshore wind farms in Italy, France, Germany, Poland, Bulgaria, Romania, the United Kingdom, and the United States, supplemented by photovoltaic installations primarily in Spain and battery storage assets. Originally founded in 1938 as a metallurgy business, ERG transitioned through oil and gas exploration before executing a decade-long strategic transformation into a pure-play "Wind & Solar" operator. It is the leading onshore wind operator in Italy and ranks among the top ten in Europe.
The company's core business consists of generating electricity from owned wind and solar assets, selling into European and US wholesale markets, and supplying corporate customers through long-term Power Purchase Agreements (PPAs). ERG also participates in regulated capacity market auctions to generate grid stability revenue. Technical capabilities include repowering and reblading of aging wind assets (e.g., the Partinico-Monreale park in Sicily), battery storage integration, and an AI-driven infrastructure inspection solution deployed with Hitachi Energy that has reduced on-site inspection time by 35%. ERG owns nearly 4 GW of installed capacity, produced nearly 6,000 GWh between 2022 and 2024 (25% growth), and in January 2026 completed a £112.9 million acquisition of seven UK wind farms (73 MW) from OnPath Energy.
Revenue is generated primarily through wholesale electricity sales (usage-based) and long-term PPAs (recurring), with capacity market payments and selective asset rotation providing additional streams. The company reports a 2025 EBITDA of EUR 540 million and Q1 2026 adjusted EBITDA of EUR 167 million (16% year-on-year growth), with 2026 full-year EBITDA guidance of EUR 520–590 million. Customer segments are dominated by corporate and industrial energy consumers procuring renewable power via PPAs and transmission system operators purchasing grid stability and capacity services, with residential end-users reached indirectly via the grid. ERG is ranked the top wind company in Corporate Knights' Global 100 Most Sustainable Corporations for 2025, and an OPA (mandatory tender offer) by ERG S.p.A. is referenced in investor relations disclosures.

Erg competitors and assessment
Company assessmentBroad incumbents
- RWE: German utility undergoing a strategic pivot from fossil generation to renewables, with a large and growing European wind and solar portfolio. Comparable to ERG in onshore wind focus and European footprint, with broader legacy generation.
- Engie: French multinational utility with major renewable energy operations across wind, solar, hydro, and storage. Comparable to ERG in European wind/solar generation and PPA offerings, particularly across France, Spain, and other overlapping European geographies.
- NextEra Energy: US-headquartered operator of Florida Power & Light and NextEra Energy Resources, the world's largest generator of wind and solar energy. Comparable to ERG in pure-play wind/solar generation focus but with a primarily US footprint and far larger scale.
- Iberdrola: Spanish global utility and one of the world's largest wind operators, with onshore and offshore wind across Europe, the Americas, and Australia. Comparable to ERG in generation technology and European market overlap, but operates a much broader regulated utility business.
- Vattenfall: Swedish state-owned utility with significant wind power operations across Northern Europe, including the UK, Germany, Netherlands, and Scandinavia. Overlaps with ERG in European wind generation and PPA-driven business, though within a broader integrated utility.
- Enel (Enel Green Power): Italian-headquartered global utility with Enel Green Power as its renewables arm, operating wind, solar, and hydro across Europe, the Americas, Africa, and Asia. Direct geographic overlap with ERG in Italy and similar renewable generation mix, but embedded within a much larger integrated utility.
Direct peers
- Orsted: Danish-headquartered global leader in offshore and onshore wind energy generation. Comparable to ERG as a pure-play renewables operator with multi-jurisdictional presence and exposure to PPA markets, though with greater offshore focus.
- Encavis: German IPP and wind/solar operator with a pan-European portfolio of onshore wind and solar PV assets. Comparable to ERG as a pure-play renewables operator focused on onshore wind generation and PPA-style revenues, though smaller in scale.
- Acciona Energía: Spanish pure-play renewable energy operator with significant wind and solar generation capacity across Europe, the Americas, and other regions. Closely mirrors ERG's wind-and-solar generation model and ESG positioning.
- EDP Renováveis (EDPR): EDPR is one of the world's largest pure-play wind and solar operators with European and US operations. Highly comparable to ERG in business model (wind/solar generation, PPAs, multi-jurisdictional footprint) and asset scale.
