Industry Guidance

The Industrial Emissions Directive (IED) is the main EU instrument regulating pollutant emissions from industrial installations, including power stations, and aims to achieve a high level of protection of human health and the environment by reducing harmful industrial emissions, in particular through the application of Best Available Techniques (BAT). Find out more about the IED on the European Commission website.

IED supersedes the Large Combustion Plant Directive (LCPD) for existing power plants from 1 January 2016 and sets new minimum standards for Emission Limit Values (ELVs).  IED also includes derogations that allow plants not complying with ELVs to continue to operate, but in a restricted way:

  • Limited Life Derogation (LLD) – plants to run maximum 17,500 hours between 1 January 2016 and 31 December 2023 and then close.
  • Transitional National Plan (TNP) - plants allocated annual emission tonnages based on historic operation, which can be traded with other plants participating in the TNP between 1 January 2016 and 30 June 2020.
  • 1,500 hour Derogation – less stringent ELVs for SO2 and NOx apply to plants which operate for <1,500 hours per year on a rolling average over a 5 year period.
  • 500 hour Derogation – no specified ELVs for gas turbines and gas engines for emergency use.

Energy UK Members have worked with the UK Environmental Regulators to develop TNP Guidance, which can be found here. A summary document is also available.

Electronic template for TNP reporting requirements developed in collaboration with the UK environmental Regulators can be found here.

A protocol for the operation of the 1,500 hour Derogation has been developed with the Regulators for installations in England and Wales, and can be found here.

A protocol for the operation of the 500 hour Derogation has been developed with the Regulators for installations in England and Wales, and can be found here.

Energy UK members in the Joint Environmental Programme have worked with the Regulators to produce a guidance document that aims to define a methodology for the Quality Assurance and calibration of continuous emission monitoring equipment (CEMs) at power plant and intends to address the monitoring requirements of the IED. The IED compliance protocol document is available here. A list of corrections to the IED compliance protocol is available here (updated March 2017). 

Electronic templates for a range of IED reporting requirements have been developed in collaboration with Regulators and are available here (updated June 2016).
