The Directive Explained

Understanding the MCPD

What is a Medium Combustion Plant?

Any engine that uses fuel where the rated thermal input is within the range of 1MWth to 50MWth. Diesel and gas engine generators rated above 400kWe are also included.

A plant may consist of a single generator or a series of generators located at the same site, with the same operator, providing electricity for the same purpose.

What is a Generator?

  • 1. Any single stationary combustion plant
  • 2. Any single mobile generator providing balancing services to the grid or connected to permanent infrastructure
  • 3. Any group of combustion plant located at the same site with the same operator, with total rated thermal input of 1MW–50MWth

When Does it Come into Effect?

December 2018

Controls apply to all new plant and generators installed from this date

From 2024

Existing plants in the >5MWth – <50MWth range must comply

From 2029

Remaining plants in the >1MWth – <5MWth range must comply

Exemptions

Who is Exempt from the MCPD?

The MCPD will affect all Medium Combustion Plants with the following exceptions:

01

Generators in installations permitted under Chapter III or II of the Industrial Emissions Directive (IED)

02

Generators on a nuclear site with a defined emergency or safety role

03

Backup generators on any other site providing they are not tested for more than 50 hours per annum and cannot supply electricity to the National Grid or operate in the balancing market

MCPD Overview

What You Need to Know

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

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 known to be hazardous to human health and the environment.

Customer Feedback

What Our Customers Say

“

I would like to say thank you for your help on this project. Things have not always been easy, and we have had a few challenges, but you — both corporately and personally — have conducted yourself with integrity at all times and have made things a lot less painful than they could otherwise have been for us.

In a few years' time I am sure the birthing pains will have been forgotten and the investment we made will have delivered the anticipated benefits — and I am confident that the level of emissions we put into the atmosphere will not give anyone cause for concern.
