MCPD

Medium Combustion Plant Directive (MCPD)

The Medium Combustion Plant Directive (MCPD) was transposed into UK law on the 30th January 2018 and will introduce a Nitrogen Oxide (NOx) limit of 190mg/Nm3 at 15% O2 to all combustion plant / generators in the 1-50MWth range, in England and Wales.

When does the Medium Combustion Plant Directive (MCPD) come into effect?

The controls will apply to new plant / generators installed from December 2018.

Existing plants must comply with the requirements from 2024 (in the >5MWth – >50MWth range) or 2029 (for the remaining >1MWth - >5MWth range).

What is a Medium Combustion Plant?

A Medium Combustion Plant is any engine that uses fuel, where the rated thermal input is within the range of 1MWth > 50MWth.

Diesel and gas engine generators rated above 400kWe are also included within the directive.

1= A plant can be made up of 1 generator or a series of generators.

What is a generator?

  1. Any single stationary combustion plant; or
  2. Any single mobile generator if providing balancing services to the grid or connected to permanent infrastructure; or
  3. Any group of combustion plant mentioned in 1) and 2) which are located at the same site, have the same operator and are providing electricity for the same purpose, with a total rated thermal input equal to or greater than 1MW but less than 50MWth.

How will the Medium Combustion Plant Directive (MCPD) affect your business?

The directive is designed to regulate emissions of SO2, NOx and dust released into the air with the sole aim of reducing these harmful substances that are known to be hazardous to human health as well as the environment.

The MCPD will affect all Medium Combustion Plants (with the exceptions listed below). Exemptions from Medium Combustion Plant Directive (MCPD):

  1. Generators in installations permitted under Chapter III or II IED
  2. Similarly, generators on a nuclear site with a defined emergency or safety role
  3. A backup generator on any other site providing it is not tested for more than 50 hrs per annum. (Backup generators are medium combustion plant that provide an emergency power supply to a site in the event of a failure of external or internal power supply. An emergency backup generator cannot supply electricity to the National Grid and must not operate in the balancing market.)
