Environment

EWE strives to link economic success with responsibility for protecting nature and the environment. Therefore, we have introduced Group guidelines on environmental management and anchored the protection of nature and the environment in our code of conduct. This applies to our power plants, our conduct and our products.

Environmental protection *NFS*

Concept

The EWE Group has established environmental management systems pursuant to EMAS and ISO 14001 for the majority of its power plants and companies. In this context, power plants are also assessed in terms of their environmental risks during failure-free and disrupted operation and, if necessary, risk minimisation measures are implemented. We also have a crisis and emergency management system which describes the steps to take in the event of an emergency such as major disruption in a power plant. EWE is expanding its onshore wind activities and is pursuing selected investments in offshore wind. We are withdrawing from marketing conventional generation, although we remain committed to conventional customer power plants and heat generation.

From 2018 onwards, the environmental protection officer of the EWE Group will prepare annual reports for the Board of Management. These reports will contain CO2 statistics as well as the results of the verification of compliance with environmental legislation. By 2020, the Group aims to lower the specific CO2-emissions from our electricity generation 1 by 40 per cent compared to 2005, expand renewable energy and withdraw from conventional generation.

Selected measures in 2017

  • We have expanded our development capacity by acquiring two wind development companies, TURBOWIND Energie GmbH and the Gewi regenerative Energien Group.
  • EWE’s subsidiary swb CREA has opened wind farms with a capacity of 15.5 megawatts (MW).
  • EWE ERNEUERBARE ENERGIEN increased its renewable energy generation capacity by acquiring four wind farms with a total output of 38 MW.
  • The highly efficient natural gas power plant Gemeinschaftskraftwerk Bremen (GKB) in which EWE holds an interest through its subsidiary swb closed its first year of operation with an output of 1.9 million megawatt hours of electricity.
The specific CO2-emissions from electricity generation have fallen from 563 grams per kilowatt-hour (g / kWh) in 2016 to 504 g / kWh 1 in 2017. Compared to the initial value in 2005, the specific CO2 figure has therefore decreased by 39 per cent. Therefore, the target of a 40 per cent reduction set in 2014 has almost been achieved already. One reason for this development is the high electricity generation of GKB. Besides the good wind year in 2017, other reasons include the fact that the RIFFGAT offshore wind farm was operational all year for the first time and that onshore wind power has been expanded. 39% Reduction of the specific CO2 emissions compared to 2005

1 Taken into consideration are conventional combined heat and power stations, power stations, waste incineration plants, wind farms, biogas plants and hydroelectric power stations of the EWE Group, including proportional capacities of holdings consolidated using the equity method, although not including emissions of block 4, which is operated by a third party using furnace gas. Unlike in previous years, a small number of estimates were factored into the CO2-emission data

2 Internal generation capacity, capacities of holdings consolidated using the equity method and block 4, which is operated by a third party using furnace gas, have been taken into consideration. In this diagram, waste to energy is fully allocated to conventional generation even if, according to the EEG, around half of the energy generated from waste is considered renewable. Only the values for the 2017 reporting year have been checked

Internal resource consumption

Concept

The responsible use of resources also involves internal energy consumption resulting from, for example, our properties or fleet of vehicles. Therefore, EWE has introduced certified energy management systems in companies with high levels of energy consumption. As we consume less energy than we generate ourselves, internal resource consumption is not part of the non-financial statement.

The energy policy of each company forms the framework for its energy targets. The objective is to optimise energy consumption and increase energy efficiency. We take this objective into account when planning, building and renovating buildings and power plants and when we procure products, systems and services. For example, by the end of 2019 we aim to lower the consumption of heat and electricity per square metre of usable floor area in our administrative buildings and communal utility services by 7.5 per cent compared to 2014.

In accordance with ISO 50001, the Board of Management and the management of the companies carry out annual inspections of the energy management system in order to ensure that it remains suitable, appropriate and effective. These inspections encompass energy policy, energy target achievement and the implementation of efficiency measures from the energy programme. They also assess compliance with statutory regulations and the effects of new legal provisions on the organisation.

Selected measures in 2017

  • By optimising the cooling of a second large data processing centre of EWE TEL and making other improvements to efficiency, the annual electricity consumption level has been lowered by around 400,000 kWh.
  • The lighting in EWE’s main warehouse has been switched to LED technology. This is expected to save over 100,000 kWh of electricity per year.
In 2017, eleven EWE Group companies with particularly high consumption levels introduced an energy management system. The electricity consumption of the administrative buildings, communal utility services and shops was lowered from 129 kWh per square metre in 2014 to 117 kWh per square metre in 2017. This represents a decrease of 9.3 per cent compared to 2014. We were therefore able to meet the target originally set for 2019 in 2017. 9.3% Reduction of the electricity consumption compared to 2014
Biodiversity

Their positive impact on our carbon footprint notwithstanding, wind farms also represent encroachment into our environment. Therefore, EWE makes sure that its expansion of wind energy is compatible with consideration for the necessary environmental specifications. It is important to EWE to create alternative habitats for plants and animals when it builds power plants. For example, when building the Bakum wind farm, EWE created alternative habitats in the vicinity. Arable land and farmland were converted and depressions and a body of water were created.
