The world of emissions legislation has changed. The introduction of the Medium Combustion Plant Directive and Non-Road Mobile Machinery regulations means compliance is essential.
The Medium Combustion Plant Directive (MCPD) is EU legislation that became law in December 2017.
The MCPD has been brought into force across the UK through 3 different regulations:
The MCP Directive (Directive (EU) 2015/2193) covers diesel engines between 1 and 50 MWth capacity. These currently fall between two other directives that cover large combustion plants and small appliances. Large combustion plants over 50 MWth are covered by the Industrial Emissions Directive (IED). Boilers, heaters and smaller appliances under 1 MWth are covered by the Ecodesign Directive (CE labelling).
EU statistics estimate there are 143,000 medium-sized combustion plants in the EU. They represent an important source of emissions of sulphur dioxide (SO2), nitrogen oxides (NOx) and dust. The MCP Directive regulates emissions of all three and monitors emissions of carbon monoxide (CO) with the sole aim of reducing these harmful substances that are known to be hazardous to human health as well as the environment.
The MCP Directive is the latest instrument to ensure the EU’s implementation of the Gothenburg Protocol under the UNECE Convention on Long-Range Transboundary Air Pollution.
The MCPD was enacted by the EU on 18 December 2015. Plants that come into operation after 20 December 2018 are classified as “new plant” in the MCP Directive; its emissions limit values (ELVs) apply as soon as the plants start operating. Older plants are classified as “existing plants” by the Medium Combustion Plant Directive. They have to conform to the MCP Directive’s ELVs by 2025 or 2030, depending on their size.
In the UK, the emissions landscape is complicated by Capacity Market considerations. Plants that supply power to the UK grid under STOR, FFR or similar agreements have different compliance requirements and timescales. These vary according to how many hours the plant operates per annum, its output capacity, when it starts operating and its type of Capacity Market contract. Please contact IPU to establish how these complex regulations apply to you.
We’ve created a really easy-to-use questionnaire where you’ll be asked various questions including where your generators are placed, the MWt Output of your plant and the date of operation. At completion of the questionnaire, we’ll be able to tell you if your plant is going to be affected by the legislation.
If you’ve completed our ‘Will the MCPD affect me’ questionnaire, you’ll know whether or not you need to comply.
If you do, IPU have a range of solutions that can be specified according to your application. These include Selective Catalytic Reduction systems (SCRs), Diesel Particulate Filters (DPFs), Diesel Oxidation Catalysts (DOCs), Gas to Liquid (GTL) fuel, Bifuel conversions, electronic governing and fuel filtration.
The NRMM is EU regulation to control emissions from engines not used on public roadways, including off-road vehicles such as construction and railway vehicles. Mobile generator sets are also included.
Non-road mobile machinery is identified as a major contributor to poor air quality in densely populated cities such as London.
Particular focus is being placed on the following emission types under the NRMM regulations: NOx, PM, Carbon Monoxide and Hydrocarbons (unburnt fuel).
Whilst generator sets that are permanently installed to a site are exempt from NRMM, trailer mounted sets, rental sets of any size and any other set that is not permanently installed will need to comply with this regulation. Engines <19 kW and >560 kW fall under the non-road mobile machinery regulation.
Non-road mobile machinery will be unable to operate in London’s Ultra-Low emissions zone and other cities operating a clean air zone without being compliant to emissions regulations. Existing NRMM must now be retrofitted with emissions abatement technologies.
In general, the emissions levels in the NRMM differ from those in the MCPD:
IPU emissions solution will ensure compliance to NRMM as well as the MCP Directive.
