North London Heat and Power Project – the Project summary
The North London Heat and Power Project is a proposal to replace the existing Energy from Waste facility at the EcoPark in Edmonton with an Energy Recovery Facility. The first step was to obtain a Development Consent Order for the proposal, which will allow us to construct and operate:
- The Energy Recovery Facility;
- Other associated works needed for the management of the energy recovery facility and for other waste management activity on site, such as the Resource Recovery Facility; and
- Any other requirements to allow the development to take place, for example, the creation of a laydown area for the storage of materials during construction.
The new ERF will produce energy from municipal waste. As the new ERF will be more efficient than the existing EfW, it will surpass the requirement under the Waste Framework Directive (Directive 2008/98/EC) to achieve an efficiency rating in excess of the prescribed level, and will therefore be classified as a recovery operation rather than disposal.
A site plan can be found here. This plan shows the extent of the EcoPark site, which covers the area within which the principal development will take place.
The application also related to associated development which is needed for the construction and operation of the ERF. This may include off site landscaping, and an off-site area for laydown during construction.
The principal development is identified by a red line area, which includes all the proposed development. You can see this detailed information in the Book of Plans (plan number A_0002)
The application for a Development Consent Order covered the following:
The principal development
Development of an Energy Recovery Facility (ERF) generating electricity using residual waste as a fuel and capable of an electrical output of around 70 MW comprising:
- two process lines, with each line having a capacity of 350ktpa, a moving grate, furnace, boiler and a flue gas treatment plant and stack;
- a steam turbine and generator set;
- "heat off-take" equipment within the ERF which will generate an initial heat supply through a connection to a separate heat network centre that will be located on the site. This separate heat network centre is not part of the Project and will be developed by the London Borough of Enfield. The separate heat network will be designed to be capable of providing heat in the region of 30 MW which will provide benefit to north and east London;
- a waste bunker with two overhead cranes and capacity to hold a minimum equivalent of 5 days of residual waste;
- air or water cooled condenser(s);
- a plant control and monitoring system;
- an emergency diesel generator;
- tipping hall and one way access ramp
The following elements are proposed as part of the development:
- the decommissioning and demolition of the existing Edmonton EfW facility (timed to take place following commissioning of new ERF and transition period of up to a year);
- a Resource Recovery Facility (RRF) encompassing a Reuse and Recycling Centre, transfer hall, and bulky waste / fuel preparation facility;
- administrative buildings and visitor centre;
- new internal weighbridges, roads and parking areas;
- hard and soft landscaping directly related to main building works
- refurbishment or replacement of the waste water treatment facility;
- new site access points from the Lee Park Way and Deephams Farm Rd, in each case subject to agreement on terms with the land owners, Lee Valley Regional Park Authority and Thames Water;
- If no agreement can be reached, then we will consider using appropriate acquisition powers through the DCO process.
Consideration is also being given to the need for the following elements which may be required as a part of the project:
- upgrade of the electricity connection to the National Grid; - there are ongoing discussions with UKPN as to the need for this;
- relocation of LWL vehicle depot and servicing;
- offsite works, including potential construction lay down areas;
- provision of an onsite water pumping station if needed for a water cooling system;
- landscaping and biodiversity enhancement of retained open spaces within the site;
- other new site accesses (construction and operational); and
- facilities for the recycling of incinerator bottom ash and recovery of metals.
