Information on the subject of energy taxes (eco-tax refund) – New legal regulations on peak balancing from 2013 onwards

Since 1 August 2012, the draft law amending the Energy Tax and Electricity Tax Act has been a matter decided by the Federal Government (§ 55 Energy Tax Act, § 10 Electricity Tax Act). This means that the relief for energy-intensive manufacturing companies will continue to be provided from 2013 under certain conditions. A new regulation became necessary at the end of 2012 due to expiring approvals by the EU Commission.

In return, manufacturing companies will continue to receive peak compensation with the introduction of an energy management system or energy audits for KMU´s. A transition period for the introduction is taken into account – but proof at the beginning of the introduction is necessary.

In addition, the German industry has committed itself in the agreement with the Federal Government to increase its energy efficiency from 2013 and to demonstrate an annual reduction in energy intensity of 1.3% from 2015. You achieve this with the introduction of an energy management system.

In a time of constantly rising energy costs, more and more companies are recognising the need to monitor their energy consumption and introduce a management system with the aim of continuously increasing energy efficiency. The legislator supports the introduction of energy management systems through state subsidy programmes and benefits.

What is an Energy Management System (EMS)?

The purpose of an energy management system is to involve upper management in the management of energy aspects. Der Zweck eines Energiemanagementsystems ist es, das obere Management in das Management von Energieaspekten einzubeziehen. Examples:

  • Producing companies with power-relevant production facilities
  • service enterprises
  • energy producers
  • Public institutions

Concentrating on the controlled use of different types of energy and energy consumption enables the resulting environmental impact and energy costs to be reduced.

DIN EN ISO 50001:2011

The European standard DIN EN 16001:2009 published in 2009 was replaced last year by the international standard DIN EN ISO 50001:2011. This describes the requirements for a globally recognized energy management system and thus forms a certifiable basis. The structure of the standard is based on the well-known PDCA principle with the aim of continuously improving energy efficiency. Based on this PDCA structure, an EMS can be integrated into existing management systems (e.g. quality (ISO 9001) or environmental (ISO 14001)).

The tasks that arise for the company are similar to those arising from other management systems; e.g.:

  • Adoption of an energy policy or adaptation of the existing environmental policy by the management
  • Determination of the energy-relevant processes in the company and description of possible energy saving potentials
  • Regular energy assessment based on consumption data, key figures and information on energy consumption
  • Definition of targets for increasing energy efficiency
  • Evaluation and determination of appropriate cost-saving measures
  • Determination and compliance with applicable legal requirements

Benefits and advantages

An energy management system

  • creates transparency with regard to energy use, consumption and costs,
  • defines the organisational structure and the activities and procedures related to energy use,
  • offers legal certainty in relation to the increasingly extensive legal requirements relating to power generation, distribution and use,
  • forms the basis for limiting the EEG levy in accordance with EEG §41 for energy-intensive companies or other planned benefits (e.g. in accordance with the current draft of the EnEfG) and
  • creates customer confidence with regard to cost transparency.

VISTRA supports you with the introduction, implementation and maintenance of an energy management system according to DIN EN ISO 50001:2011.


Our qualified project managers

  • carry out an initial stocktaking at your locations and determine the deviations from the standard requirements,
