Climate protection and generation

Our objective: We reduce the climate impact of our energy generation methods.

  • 30% of electricity generation is from renewable sources
  • Renewables: 322 MW installed output
  • EWE welcomes the outcome of the Climate Change Conference in Paris

As an energy service provider, we bear a particular responsibility for protecting the climate. The key goal is to reduce CO2 emissions and is anchored in the EU’s climate targets for 2030. We are making our contribution by increasing the efficiency of our conventional power generation systems and expanding renewables.

We can gauge our progress by the reduction in CO2 emissions per kilowatt-hour of electricity generated. By 2020, we aim to have cut these emissions by 40% compared to 2005. In 2015, we were able to reduce our specific CO2 emissions to 538 g/kWh. This is equivalent to a reduction of 35.3% compared to 2005.

Expansion of renewables: Focus on wind power

We have been operating onshore wind farms for 25 years. We have also been operating offshore wind farms for over five years. EWE now operates onshore wind farms with an output of around 164 MW and offshore wind farms with an output of around 137 MW, with wind energy thus making a significant contribution toward lowering CO2 emissions in 2015.

With the Trianel public utilities partnership, EWE put its name to a joint venture extending through the second stage of the expansion of the Trianel Borkum West wind farm. A further 200 MW in capacity is to be added to the 40 turbines off the coast of Borkum, already producing an output of 200 MW. Borkum West was then able to supply 200,000 households with electricity. EWE holds a 40% share in the development of this project and is responsible for the technical project development.

Make conventional power stations more efficient 

EWE still finds it essential to use fossil fuels in order to balance out the weather-related fluctuations in the availability of renewable energies. EWE subsidiary swb operates conventional power stations, generating electricity from refined coal and natural gas, and also operates two waste processing plants. swb is constantly working on improving the efficiency of its power stations. With environment management systems, swb creates the framework for monitoring and ensuring compliance with legal requirements and its own internal goals.

Biogenic fuels are used to replace fossil fuels in Unit 6, which is powered by refined coal, thus minimising CO2 emissions. In addition, the proportion of electricity from refined coal in the EWE own-generation portfolio has also decreased because coal-fired Unit 5 was put into cold standby in 2014. This means that it is just available as an emergency reserve in the event of bottlenecks.

Constructing a steam and gas turbine power station 

In Mittelsbüren, swb is joining forces with partners from the energy industry to build a gas and steam turbine power station that uses natural gas, supporting the energy revolution with its high level of efficiency and flexibility. The power station is expected to become operational in the fourth quarter of 2016.

Wind power: Nature conservation aids acceptance 

In addition to their positive effects on our carbon footprint, wind farms also have an environmental impact. For this reason, EWE creates conservation areas for animals and plants to balance out this effect for each of its construction projects, for instance in Hatten. EWE started construction of eight turbines there in 2015, each with a capacity of 3.3 MW, that are due to start generation in summer 2016.

The habitats for birds and insects that were destroyed by the wind farm are being reconstructed in the immediate surroundings. A protective mechanism for bats has also been incorporated: Because animals tend to go out hunting on nights when wind levels are low, the wind farm is switched off then so that they do not collide with the rotor blades.
