onshore and offshore wind power
For over 25 years EWE has been reliant primarily on wind power as it expanded its renewables. EWE operates plants with a capacity of around 220 MW onshore and around 142 MW offshore. A wide range of environmental protection measures have been implemented for the Hatten wind farm (with eight turbines). The 16 turbines at the Köhlen wind farm are a joint project between PNE Wind AG and EWE; Köhlen is one of the largest wind farms in northern Germany. Private individuals and municipalities will be able to acquire stakes in both wind farms.
CO2 emissions from electricity generation
The increase in specific CO2 emissions from electricity generation is due primarily to the decrease in generation from wind power. Compared to 2015, 2016 was a poor wind year. This combined with the fact that the Riffgat wind farm was rendered non-operational for a number of months by a technical problem resulted in lower generation from wind power. The opening of the high-efficiency gas and steam turbine plant in Bremen in December 2016 has not yet had a relevant effect on the CO2 emissions for the reporting year.

Charging infrastructure: the key to success in e-mobility
E-mobility cannot become more widespread without a larger network of charging stations. EWE and its subsidiary swb in Bremen operate more than 240 public charging points throughout Germany (as at 2016), 120 of which are located in the EWE service area in the north west. EWE has also been awarded a contract by an e-fleet customer with around 100 charging points. In the vehicle fleet segment, EWE’s services include connecting charging points to the grid, operation and maintenance as well as metering and the delivery of energy.

Our focus in the future
We will continue to augment electricity generation from wind power. We plan to invest around 116 million euros in this in 2017. With regard to e-mobility we will spur on the expansion of our charging infrastructure in the north west in future. We aim to double the number of charging points in the EWE service area in the north west by late 2017. For example, EWE is installing charging points at 60 locations run by the supermarket chain Edeka. We remain focused on holistic solutions for our private customers. For example, with wall boxes we can make it possible to charge electric vehicles quickly at home. Using solar panels in combination with an EQOO energy storage system, home owners can independently cover 70 per cent of their electricity requirements on average.
As a company actively involved in shaping the energy transition, we want to promote energy generation from renewable sources. We develop solutions to balance out the fluctuations in renewable energy generation caused by the weather and ensure a reliable energy supply at all times. However, it goes without saying that we strive to treat our environment responsibly. We monitor and reduce our energy consumption throughout our Group, we make our employees aware of the impact of what they do and we train them in energy-related aspects that are of significance to the environment. We are working hard to cut the CO2 emissions from our own electricity generation activities. We are applying our expertise to develop environmentally friendly solutions and energy-saving products.
SELECTED MEASURES IN 2016
- Opening of Hatten and Köhlen wind farms
- Energy management expanded: with EWE AG, EWE NETZ and EWE WASSER, eleven Group companies are now certified:
- EWE AG: in partnership with EWE TEL, around one million kilowatt hours (kWh) of electricity have been saved in a data processing centre. Measure: optimised cooling of server rooms
- EWE NETZ: gas pressure monitoring systems identified as one of the largest energy consumers. Measure: The company is examining the potential for optimisation of the gas pre-heating process
- EWE WASSER: electricity requirements of the pumping station at the waste water purification plant in Cuxhaven lowered by approx. 90 per cent. Measure: modernise the waste water pumping facility
Expansion of wind power
24 new turbines with a total capacity of almost 75 megawatts (MW) were connected to the grid in 2016. EWE granted some residents and landowners a stake in the turbines, e.g. with a savings certificate model.
Ongoing reduction of energy consumption
In 2016 we almost met our target of having twelve companies certified by 2020. On the basis of specific energy-saving targets in the companies, we are continuously identifying potential ways to save energy and deriving specific energy-saving measures from them.
Temporary increase in specific CO2 emissions from electricity generation
In 2016 the specific CO2 emissions of the electricity generated by EWE were higher than in 2015 (see image). Nevertheless, we expect to reach our target of 40 per cent lower emissions in 2020 compared to 2005. In 2016 the reduction was 32 per cent compared to 2005. In order to meet this target, we will expand wind power with even more determination over the next few years, including in partnership with private individuals and partner companies. EWE currently holds a 37.5 per cent stake in the Trianel Windpark Borkum II offshore wind farm.
