The Medium Combustion Plant Directive (MCPD) is a new Directive which introduces emission controls on new combustion plants from December 2018 and existing plants in 2025 and 2030, depending on size. The Directive was transposed into UK law in December 2017 by means of The Environmental Permitting (England and Wales) (Amendment) Regulations 2018.
The MCPD regulates the emission levels of all combustion engines where the rated thermal input (gross fuel input) is between 1 and 50MW (this applies to each individual unit). For generator sets this is equivalent to a power output roughly between 330 kW and 17 MW. Diesel or gas engine generators rated above 400kVA are also applicable.

The MCPD sets a limit of 190mg of NOx /Nm3 (at 15% O2).
(“NOx” means various oxides of nitrogen which are a usual byproduct of the combustion process. High concentrations of NOx have been found to be harmful to health)
Any engines that ‘combust’ of burn fuel (such as diesel or gas) in order to produce power, and with a rated thermal input between 1 and 50MW. For diesel engines this roughly equates to power output of 330 kW and 17 MW
Yes, there are some exceptions:
The restrictions will apply to newly installed plant from December 2018.
For existing plants;
The accepted method to reduce NOx emissions from combustion engines is by employing Selective Catalytic Reduction (SCR). This multi-stage system treats the exhaust gases and can achieve NOx reduction of upto 98%. GTL Systems is a leader in the field of SCR systems, and have supplied solutions for all types of combustion plant.
Our SCR system, G-NOx™ has been installed on numerous power generation plants from small mobile generators to large STOR projects. But that’s not all…
As well as the SCR itself, we can design, fabricate and install all of the supporting structures, gantries, walkways and other ancillary equipment (such as AdBlue tanks).
We can also provide;
Maintenance/service packages and extended warranty to ensure equipment is being looked after.
In addition to our standard site services, we can also arrange specialist consultation who can carry out detailed analysis of the application, including modelling for exceedance, permitting etc.
