Sonnedix

What Sonnedix does

Sonnedix is a privately held global Independent Power Producer (IPP) founded in 2009 and headquartered in London, with European operations centered in Madrid. The company acquires, develops, builds, and operates utility-scale renewable energy assets — primarily solar PV, increasingly co-located with battery energy storage systems (BESS), and with a smaller wind component — across nine countries: Spain, Italy, Portugal, France, Germany, Poland, the United Kingdom, Japan, and Chile. As of 2026, Sonnedix reports over 10.8 GW of combined operational and development capacity, having grown roughly threefold since 2018 under CEO Axel Thiemann, and operates through wholly owned regional subsidiaries including Sonnedix Japan and Sonnedix Chile (the latter incorporating the 2022-acquired ARCO platform).

The commercial model is anchored on long-dated Power Purchase Agreements (PPAs) of 10–25 years with corporate and industrial offtakers such as Equinix, Renfe, Endesa, and Volkswagen (via VW Kraftwerk GmbH), supplemented by wholesale energy market sales, capacity auctions (e.g., 7.9 TWh won in Italy's Energy Release 2.0), regulatory credits such as Guarantees of Origin, and project development/EPC services. Sonnedix structures both fixed-price and indexed-price PPAs, plus hybrid PV+BESS products (e.g., a 262.8 GWh hybrid hedge with Endesa) and multi-country portfolio solutions for multinational customers. The company secured a CNMC licence in June 2026 to trade and supply electricity directly to end customers in Spain, marking a step into retail supply.

Financing is debt-led and institutionally backed: J.P. Morgan Asset Management has been the Flagship financial partner since 2014, with Amundi and other institutions also participating; cumulative disclosed debt facilities since 2021 exceed €6.5 billion, including a record €3.25 billion refinancing in December 2024. Operational technology is supported by supply partnerships with Tesla (Megapack) and Sungrow (BESS) for storage hardware, Palantir for asset performance analytics, and Eiffage Energia Sistemas for EPC. Sonnedix has held a GRESB five-star ESG rating for eight consecutive years and is a Climate Pledge signatory committed to net-zero by 2040.

Broad incumbents

• RWE Renewables: Renewables division of German utility RWE AG, one of Europe's largest operators of wind and solar assets. Comparable as a major incumbent IPP pursuing scale, hybridization, and corporate offtake arrangements across European markets where Sonnedix operates.
• Enel Green Power: Renewable energy arm of Italian utility Enel, one of the world's largest renewable operators. Comparable as a major solar/wind/storage IPP; Sonnedix acquired 416 MWp of Chilean capacity from Enel Chile in 2023, making them both competitor and counterparty.
• Engie Renewables: Renewables arm of French utility Engie, operating large-scale wind, solar, and storage assets globally with a focus on corporate PPAs and hybridization. Comparable as a major European incumbent with overlapping customer base and similar multi-geography platform ambitions.
• Iberdrola Renewables: Renewable generation arm of Spanish utility Iberdrola, a global leader in onshore and offshore wind plus solar. Comparable as a major European incumbent renewable operator with deep Spanish exposure; competes for the same corporate offtake and capacity-auction wins in Iberia.
