What They Do

ENERTRAG SE focuses on integrated power plants that combine wind, solar, hydrogen, battery storage, and grid infrastructure under the Verbundkraftwerk® model. This model enables the generation of demand-oriented electricity, heat, and hydrogen to replace fossil fuels (Source: enertrag.com). The products and services cover the entire value chain: project development, planning, construction, and operation of over 1,300 wind turbines at six European locations, as well as manufacturer-independent services from 16 German stations (Source: windindustry-in-germany.com). ENERTRAG has its own portfolio that generates around 2,000 GWh annually from wind and solar, with an operational capacity of over 3,000 MW and a 660 km long proprietary feed-in grid (Source: enertrag.com). Target markets include utilities, industry, and regions seeking grid stability, with customers ranging from local grids to international hydrogen buyers (Source: enertrag.com). ENERTRAG differentiates itself through its pioneering status in hybrid power plants and emphasizes local acceptance through species protection, public participation, and agreements with landowners (Source: windindustry-in-germany.com).

Projects & Track Record

Key completed projects include the world's first hydrogen hybrid power plant in Prenzlau, Germany, which began commercial hydrogen production in 2011. Other significant projects are a 20 MW solar field with battery storage at Uckermark-Kreuz, which opened in 2023, and a 186 MW wind field in Poland, inaugurated in 2022 (Source: enertrag.com). ENERTRAG also realized the first French wind field in 2002, which reached 200 MW installations by 2017, as well as the Nechlin wind-based thermal storage facilities that opened in 2020 (Source: enertrag.com). Current major projects include the Hyphen hydrogen project in Namibia, launched in 2021, and the TAMBOR hydrogen project in Uruguay (2021) (Source: enertrag.com).

Recent Developments

In the past two years, ENERTRAG announced EU funding for its IPCEI electrolysis corridor in East Germany and nominated the Hyphen Namibia project as a strategic foreign project (both in 2024). Additionally, the first Polish wind farm was opened in 2022, and the transition to the SE structure was completed with Dr. Gunar Hering as CEO (Source: enertrag.com). The management board was expanded on January 1, 2025, with Dr.-Ing. Anne Bendzulla for the new "Generation" department, focusing on operational excellence, digitalization, and energy marketing (Source: renewable-energy-industry.com).

Working at ENERTRAG

ENERTRAG employs over 1,200 staff in various areas such as project development, engineering, construction, operations, and service. The main employment occurs at the headquarters in Dauerthal, Germany, as well as at operational sites in Germany, France, Poland, and South Africa (Source: enertrag.com). The corporate culture emphasizes regional roots, with over 500 annual tours for locals and schools to foster acceptance (Source: enertrag.com). Although no specific employee benefits are documented, the private structure and growth suggest competitive packages in the renewable energy sector (Source: enertrag.com).
