Our energy sources

Uniper operates roughly 19.5 GW of generating capacity in Europe, ranking us among its largest power producers.

Our energy sources

Our generation mix

Our flexible assets - especially our gas turbines and hydro plants - can ramp up at short notice, enabling them to balance out fluctuations in wind and solar output. As renewables increasingly dominate Europe’s grids, this agility will be vital to keeping the power system reliable and resilient.

Our power portfolio is diverse, and we are committed to steadily transforming it to contribute to the energy transition. We’re closing coal-fired power plants, converting some of them to gas, sourcing green power from numerous producers of renewable energy, as well as building our own wind and solar farms. We’re also exploring options to make our gas-fired power plants even climate-friendlier. This includes converting them to run on low-carbon and renewable hydrogen or biofuels or capturing and storing their carbon emissions. This would make one of our key capabilities - providing flexible power - carbon-neutral. It’s all part of our commitment for our entire business to be carbon-neutral by 2040. We intend to be more than halfway there by 2030.

Our gas trading and low-carbon gases

Uniper is also one of Europe’s leading gas traders. Our diversified portfolio consists of over 130 TWh of long-term LNG and pipeline gas contracts, as well as short- and medium-term market transactions. In addition, Uniper is at the forefront of developing and integrating renewable and low-carbon gases, including hydrogen.

Pioneering renewable and low - carbon gases 

Uniper is a pacesetter in developing and integrating renewable and low-carbon gases. We are helping Europe take the first meaningful steps toward eventually decarbonizing its gas supply.

Hydro  

Uniper has been producing hydropower for over 125 years. With 185 power plants in Germany and Sweden, hydropower is an important component and one reasons why 20% of our generation capacity is already zero-carbon.

Wind and solar  

Uniper aims to have 8 GW of ready-to-build renewable projects by 2030. Our focus is on onshore wind and solar power plants in Europe. In this way, we want to contribute to achieving our climate targets.

Hydrogen  

Uniper is building a hydrogen portfolio to accompany the phase-out of natural gas. As a pioneer in hydrogen, we are active worldwide and are conducting projects to make hydrogen mainstay of Europe’s energy supply.

Nuclear  

Uniper is Sweden's second-largest nuclear power plant operator. Uniper operates three active nuclear power plants - OKG, Ringhals, and Forsmark - and plays a crucial role in grid stabilization and promoting low-carbon electrification.

Coal 

In 2024, we closed further coal-fired power plants in Germany and the UK - a major step toward phasing out coal. 2.5 GW of generation capacity remains as grid reserve to ensure security of supply.
