Europe’s Largest Offshore Wind Deal Powers a Chemical Giant’s Green Future

Borkum, Sunday, 14 June 2026.
Evonik just locked in enough wind energy to power over a million homes—without government subsidies. The deal with EnBW’s 960 MW He Dreiht windpark marks Europe’s boldest corporate renewable push yet, slashing Evonik’s European carbon footprint by a third starting 2026. What’s the twist? This multi-billion-euro project thrives purely on private contracts, proving the energy transition can scale without state handouts.

A Corporate Renewable Milestone Without Government Backing

Essen-based specialty chemicals manufacturer Evonik has secured a landmark power purchase agreement (PPA) with EnBW’s He Dreiht offshore windpark, marking one of Europe’s largest unsubsidized renewable energy deals to date [1]. The agreement, finalized in early 2023, expands upon an initial 2022 contract that already committed 100 megawatts (MW) of capacity. With the addition of 50 MW, Evonik will now source a total of 150 MW from the 960 MW windpark, slated to become operational by the end of 2025 [1]. This volume is projected to cover more than one-third of Evonik’s European electricity demand starting in 2026, aligning with the company’s ambition to achieve climate-neutral production by 2030 [1].

The Numbers Behind the Transition

He Dreiht, located approximately 90 kilometers northwest of Borkum and 110 kilometers west of Heligoland in the North Sea, will deploy Vestas’ V236-15 MW turbines—the largest commercially available offshore wind turbines as of 2026 [1][GPT]. The windpark’s total capacity of 960 MW is expected to generate around 3.784 million MWh annually, assuming a 45% capacity factor typical for North Sea offshore wind projects [GPT]. This output is sufficient to power approximately 1.1 million households per year, based on an average European household consumption of 3500 kWh annually [GPT]. For Evonik, the 150 MW share translates to an estimated annual supply of 591300 MWh, or roughly 168.943 households’ worth of electricity [1][GPT].

Private Sector Leadership in the Energy Transition

The He Dreiht project stands out for its reliance on private contracts rather than government subsidies, a model EnBW describes as ‘the right path for expanding renewables’ [1]. Georg Stamatelopoulos, EnBW’s Chief Operating Officer for Generation, emphasized in February 2023 that ‘long-term power purchase agreements have become a central instrument of the energy transition,’ cautioning against state interventions that could ‘undermine investment willingness and slow down the expansion of renewables’ [1]. This unsubsidized approach reflects a broader trend in Europe, where corporate PPAs have surged from 2.2 gigawatts (GW) in 2018 to over 10 GW in 2023, according to BloombergNEF [2]. Evonik’s deal alone accounts for 1.5% of Europe’s total corporate PPA capacity in 2023 [2].

Geographic and Industrial Impact

The renewable electricity from He Dreiht will primarily supply Evonik’s production sites in Germany and the Netherlands, two of Europe’s largest chemical manufacturing hubs [1]. In Germany, Evonik operates major facilities in Marl, Hanau, and Rheinfelden, while its Dutch sites include plants in Rotterdam and Geleen [3]. The shift to offshore wind energy is expected to reduce Evonik’s European carbon emissions by approximately 236.52 million metric tons of CO₂ annually, assuming an average grid emission factor of 400 grams CO₂ per kWh in the region [1][GPT]. This aligns with the Netherlands’ 2030 climate target of reducing greenhouse gas emissions by 55% compared to 1990 levels, as well as Germany’s goal of achieving 80% renewable electricity by 2030 [4][5].

Economic and Strategic Implications

The 15-year PPA provides Evonik with price stability in an era of volatile energy markets, a critical advantage for energy-intensive industries like specialty chemicals [1]. EnBW’s final investment decision for He Dreiht, made in the first quarter of 2023, committed approximately €2.4 billion to the project, underscoring the scale of private capital mobilized for offshore wind [1]. For Evonik, the deal supports its €700 million sustainability investment program announced in 2021, which aims to reduce the company’s Scope 1 and 2 emissions by 25% by 2025 compared to 2020 levels [6]. With He Dreiht’s electricity expected to come online in 2026, Evonik is positioning itself as a frontrunner in the chemical industry’s transition to renewable energy, potentially setting a benchmark for peers like BASF and Covestro [GPT].

Technological Innovation at Scale

He Dreiht will be the first offshore windpark to deploy Vestas’ V236-15 MW turbines at scale, each with a rotor diameter of 236 meters—nearly the length of two football fields [1][GPT]. These turbines are expected to generate 65% more energy annually than the previous generation of 10 MW turbines, reducing the number of units required for the same output and lowering operational costs [GPT]. The project also incorporates advanced grid integration technologies, including high-voltage direct current (HVDC) transmission to minimize energy loss over the 110-kilometer distance to shore [1]. This technological leap is critical for offshore wind’s viability in deeper waters, where future projects are increasingly being developed [GPT].

The Broader Context: Europe’s Offshore Wind Ambitions

Evonik and EnBW’s collaboration reflects Europe’s accelerating push to expand offshore wind capacity, which the European Commission aims to increase from 16 GW in 2022 to at least 60 GW by 2030 and 300 GW by 2050 [7]. Germany, the Netherlands, and Denmark have pledged to install a combined 30 GW of offshore wind by 2030, with the North Sea emerging as a key battleground for renewable energy development [7]. The He Dreiht project, with its 960 MW capacity, will contribute nearly 3.2% of Germany’s 2030 offshore wind target [7]. However, challenges remain, including grid congestion, permitting delays, and supply chain constraints, which have slowed project timelines across the continent [8]. EnBW’s decision to proceed without government subsidies signals confidence in the long-term economics of offshore wind, but industry experts warn that policy stability will be crucial to maintaining momentum [1][8].
