What Stena Renewable does

SR Energy AB (formerly Stena Renewable) is a privately held Swedish renewable-energy company that develops, builds, and retains long-term ownership of land-based wind parks across southern Sweden. The company was founded in 1999, is headquartered in Göteborg, and operates one of the largest onshore wind portfolios in southern Sweden with 241 operational wind turbines across 12 wind parks producing a combined 2,727 GWh of renewable electricity per year — sufficient for several hundred thousand Swedish households. A 25-turbine/147 MW park at Horshaga was commissioned in 2025 and Tvinnesheda (47 turbines, 600 GWh/year, southern Sweden's largest at the time) entered service in 2022; the pipeline includes 15+ additional wind parks plus the Kolstad solar park under development.

The technology stack is conventional utility-scale wind: turbines supplied by Vestas, GE Energy, and Nordex across parks (e.g., Vestas V136 3.8 MW units at Kronoberget, GE 2.75 MW units at Grytsjő/Uddared, Nordex 2.5 MW at Möckelsjöberget), with internal 30 kV networks and fiber-optic control systems inside each park. Foundations at several sites use bergsförankrade (rock-anchored) designs — rock bolts and post-tensioning into bedrock — which reduce concrete volumes and CO2 footprint relative to gravity foundations. The company has begun diversifying into solar via the Kolstad solar park.

SR Energy monetizes electricity by feeding it into the Swedish national grid at market (spot) rates and retains ownership through the full 30–35 year operational life of each asset. Some parks are wholly owned; others are co-owned with partners such as DalaVind, Borlänge Energi, Falu Energi & Vatten, and Dala Energi (e.g., at Riskebo). The customer is effectively the Swedish grid system rather than end consumers; the company also operates a community-engagement program called Vindbonus, distributing 10,000 SEK per turbine per year to local associations through juried allocations — a distinctive feature supporting local acceptance in a market where wind development frequently faces community opposition. Grid connection partners include E.ON (transformer stations and 130 kV lines for Tvinnesheda and Horshaga) and Hedemora Elnät (Riskebo).

Revenue model

1. Wind Electricity Generation & Sales: SR Energy generates and sells renewable electricity from its fleet of 241 wind turbines across operational wind parks. Electricity is fed into the Swedish national grid. Revenue derives from electricity sales at market prices.
2. Long-Term Wind Park Ownership: The company retains ownership of wind parks through their operational lifetime (approximately 30-35 years), generating stable long-term cash flows from electricity production. Ownership stakes vary: some parks are 100% owned, others are co-owned with partners such as DalaVind, Borlänge Energi, Falu Energi & Vatten, and Dala Energi.

Core offering

Stena Renewable (legal entity SR Energy AB) develops, builds, owns and operates land-based (onshore) wind power generating parks in southern Sweden. The company feeds electricity from 241 wind turbines across 12 operational wind parks into the Swedish national electricity grid, with an installed capacity of approximately 2,727 GWh/year. It also has 15+ wind parks and a solar park (Kolstad) in development, and operates a community benefit program (Vindbonus) that distributes SEK 10,000 per turbine per year to local communities.

Product overview

SR Energy operates a portfolio of land-based wind farms and solar parks across southern Sweden. The core offering consists of wind park operations with 241 turbines across 12 operational parks, producing approximately 2,727 GWh annually. The company is expanding into solar energy with at least one solar park under development. A complementary community engagement program called Vindbonus distributes annual funds to local organizations near wind park sites.

Others

• Skovbakken? (placeholder removed): Enercon is a major German manufacturer of wind turbines and a direct supplier to many European wind IPPs. Relevant as an ecosystem participant / potential OEM partner analogous to SR Energy's existing Vestas/GE/Nordex relationships, not as a direct competing IPP.
