Enfield Biomass CHP Update

19 March 2013: Updates from developer Kedco of the biomass combined heat and power (CHP) plant being developed in Enfield (see previous post here for a lot more detail on the scheme).

The Telegraph reports that “The project, which has full planning and environmental permission for the conversion of 60,000 tonnes of waste timber per annum into up to 12MW of electricity and heat, remains on track to reach financial close and start construction in the third quarter of 2013. Chief executive Gerry Madden said: “The company has a clear plan in place for the Enfield Biomass CHP project with the key objective being to reach financial close by Q3 2013.

“Given the flagship nature of the project, which is located in the London area within the M25, the company is pleased to have received numerous enquiries from various parties interested in participating in the project, and we look forward to finalising this shortly.”

Kedco’s website additionally states that: “The company has had discussions with a number of potential large blue chip offtakers for both the electricity and heat which will be generated by the project.”

25 heat network projects being supported in London

November 2012: A recent speech by Ed Davey, Secretary of State at DECC on the department’s emerging policy around heat energy highlighted how the efficient use of heat is being promoted in the capital through its promotion of district heating. Mr Davey stated:

“London contains an example of the potential. The Greater London Authority is supporting 25 heat network projects. These have the capacity to leverage over £230 million of investment.”

A recent Mayoral question provides a little more detail on where these schemes are:

“The Decentralised Energy Project Delivery Unit is currently supporting the development of 25 decentralised projects. The following lists the activities with the boroughs:
Projects at procurement: Brent and Camden;
• Projects at post-feasibility: Croydon, Enfield, Haringey, Waltham Forest and Westminster;
• Projects at feasibility: Southwark, Islington, Hammersmith and Fulham, Newham, Sutton;
• Projects at pre-feasibility/energy master planning: Hillingdon, Ealing, and Westminster.”

Further information on Brent’s South Kilburn DE project can be found here.
Details of the innovative scheme being supported by Camden in Gospel Oak can be found here (and recent October newsletter here), which is using heat from a Combined Heat and Power (CHP) plant situated in the Royal Free Hospital, to provide low carbon affordable heat to nearby residents.
Other information can be found in the various borough heat map reports posted on www.londonheatmap.org.uk

Delays to North London waste processing plant

September 2012: Key to the proposed North London Waste Plan (NWLP) – currently under development – is the development of a new ‘Mechnical and Biological Treatment’ (MBT) plant at the former Friern Barnet Sewage Works at Pinkham Way. An independent planning inspector has however recently ruled that the Plan has not been properly consulted on with neighbouring boroughs and hence developers (see below) for the project  must look again at resubmitting their proposals.

The NWLP sets out the planning framework to 2027 for waste management in the seven North London boroughs – Haringey, Barnet, Camden, Enfield, Hackney, Islington and Waltham Forest – which together are known as the North London Waste Authority (NWLA) . It identifies sites for waste management use and sets out policies for determining waste planning applications.The Plan has been under development now for several years, and the inspector’s decision will now knock the timetable for the adoption of the councils’ proposals.

The planning application for the Pinkham Way is a separate process to the overall plan and is currently on hold. The ‘mythbusters’ section of the NWLA website sets out that the MBT to be based there will be used to manufacture a solid fuel from waste that is left over after as much recyclable material as possible has been extracted; that fuel will then be transported to one of two sites outside of north London where there is a need for energy (heat and electricity).” This type of fuel is usually called SRF or solid recovered fuel.

The website goes on to say that NO waste incineration will take place on the site, and no plans are being made to accommodate incineration at Pinkham Way now or in the future.”

NWLA also state that “The carbon impacts of waste are mostly in the treatment of the waste rather than in its transportation, but even so we are seeking to have the Solid Recovered Fuel (SRF) delivered to the fuel-user by rail or water transport to minimise this. It is also important to note that we are making SRF precisely so that the maximum carbon benefits of combined heat and power can be reaped at a location where a suitable demand exists. The alternative would be to build a new incinerator that recovers only electricity and that wastes the heat; and this is very specifically what we are not proposing to do.”

A lot more information on the NWLA’s proposals – and the active campaign directed against them – is provided at the pinkhamwayincinerator.blogspot.co.uk website.

Funding for London biomass schemes

January 2012: DECC’s Bio-energy Capital Grants Scheme supported “biomass-fuelled heat, and combined heat and power projects in the industrial, commercial and community sectors in England.” A spreadsheet has just been released providing details of projects supported by rounds 1, 3, 4, 5 and 6 of the scheme.  Projects are not listed with any specific geographic information however from a quick review it appears that only 4 of the 215 schemes supported appear to be in London, which are:

  • Hale Village in Tottenham (entry 161 on the spreadsheet)
  • A school in Sutton (entry 178)
  • An unspecified London fire station (entry 180)
  • East Barnet School (entry 197)

Enfield Gasification Scheme

21 November 2011: An update on Irish developer Kedco’s plans to develop a biomass gasification scheme in Enfield which it believes have become more positive as a result of the recent proposed changes to the renewable obligation

The project received planning permission in October 2010 to build a c. £45 million biomass wood gasification plant in Enfield capable of generating 12MW of electricity and 10MW of heat and – as the article linked above explains – has secured a supply deal with a company processing waste wood from construction and demolition. Kedco report that tenders currently being prepared to source a suitable contractor for the proposed construction of the plant.  Details submitted at the time of application in relation to a ‘heat output assessment’ for the facility can be viewed here and para 6.3.1 onwards  of the planning officer’s report (report also here) on the application provide details of the scheme’s proposals to export heat to some nearby sites.

Three schemes bid to generate heat and power from North London’s waste

October 2011: Three bids have been submitted to the North London Waste Authority (NLWA) to generate energy from the 300,000 tonnes of solid recovered fuel (SRF)  created from the 500,000 to 600,000 tonnes of North London’s waste that cannot be recycled  or composted.
The NWLA is a statutory waste authority managing the disposal of municipal waste from seven London local authorities (Barnet, Camden, Enfield, Islington, Hackney, Haringey and Waltham Forest) and this procurement is one of two that NLWA is running to provide a “long term and sustainable waste management solution for North London”.  A separate procurement is being run that will involve recycling or composting half of North London’s waste, producing the fuel and minimising the landfilling of municipal waste.
The contract for the use of SRF will be available from 2015 for up to 25 years and the NLWA states that it “is striving to achieve the most efficient form of energy recovery. This could be with the fuel being used in a Combined Heat and Power (‘CHP’) plant, located close to where the energy demand is.”
The NWLA have provided updated details of the three bids, all of which utilise CHP technology  on the following news release.

  • Covanta Energy project is the only one based in London and is proposing a Combined Heat and Power plant at the Tate & Lyle sugar refinery site at Silvertown, East London. The Covanta proposal involves the transport by barge of SRF from Edmonton to Silvertown and this will support the further development of London rivers for freight transport use. Covanta will shortly begin consultations with the local community and relevant authorities ahead of a planning application in mid 2012.
  • E.ON/Wheelabrator Technologies is proposing a CHP plant at DS Smith Paper’s site at Kemsley Mill, Sittingbourne, Kent.
  • Veolia Environmental Services (UK) wants a CHP enabled power plant at an existing industrial site in Hoddesdon, Hertfordshire.

The winning proposal will be selected from one of the three shortlisted candidates during the next 12 months using an evaluation framework that focuses on the quality and cost of the solution.
Further information on how SRF is produced is set out by the NWLA here.

Proposals for a North London Decentralised Energy Network

August 2011: Enfield have released their plans for the development of one of the largest “green developments in the country“. The Meridian Water development aims to create 5,000 new homes, 3,000 new jobs, three schools, a nursery, doctors’ surgery, shops, parks, open spaces, leisure facilities, a police drop in centre and significant improvements to transport links on the 90 hectare site at the heart of the Upper Lee Valley. As well as playing a major part in regenerating Edmonton and its surrounding areas, the £1.3 billion project aims to be low carbon, becoming one of the main hubs within the proposed North London Decentralised Energy Network.

Details are set out in Enfield’s Meridian Water Masterplan Consultation document which set outs that:
“Meridian Water presents an extraordinary opportunity for a site-wide district heating network which takes advantage of the proposals for a Borough wide decentralised energy network that builds on the infrastructure assets of the Lee Valley. The nearby energy centres and industrial corridor creates the prime opportunity to capture the released heat from these operations to deliver secure, low cost, low carbon energy and heating to businesses and homes in Meridian Water and beyond.”

The deadline for response to the consultation document is 5th September 2011

London’s Power Stations

30 June 2011: DECC’s annual Digest of UK Energy Statistics (DUKES) has just been published providing a welcome summer reading challenge for all energy-geeks… DUKES is principally concerned with national level energy statistics, and hence does not provide regional breakdowns in most instances (those are usually set out in separate articles in DECC’s quarterly journal Energy Trends). However, there a few issues areas worth looking at. In the first instance, it’s useful to be aware of what power plants operate within London itself, which in total contribute only a small percentage of London’s total electricity demand. The following London schemes are listed in the ‘Power Stations in the UK’ table in Chapter 5 of DUKES, to which some additional information/links have been added to below:

  • Barking Power – a gas fired Combined Cycle Gas Turbine (CCGT) of 1000 MW (megawatts) generation capacity, which first started operating in 1994
  • Citigen (London) UK Ltd  – based in Charterhouse Street in Smithfields and owned and operated by E.ON, this scheme is fuelled by  gas and gas oil, and is rated 31 MW and first started operating in 1995. The unit operates in Combined Heat and Power (CHP) mode providing heating, and also cooling (via chilled water) distributed by a district energy network to a number of customers in the City area.
  • Thames Valley Power – a joint venture between EDF Energy and ATCO Power, this  Gas/Gas oil 15MW CHP has been operating since 1995 at Heathrow Airport.
  • London Heat & Power Company –  a 9MW gas CHP based at Imperial College which started operation in 2009.
  • Barkantine Heat & Power Company – A 1MW gas fuelled CHP with district heating system based on the Barkantine Estate in Tower Hamlets
  • Taylors Lane – Taylor’s Lane Open Cycle Gas Turbine (OCGT) station, situated in Willesden is operated by E.ON and has two gas turbine units fired on natural gas with a total capacity of 132MW and began generating in 1979.
  • Enfield Power Station– E.ON owned and operated 400MW gas turbine scheme which began generating in 1999.
  • SELCHP – South East London Combined Heat & Power Ltd (SELCHP) 32 MW waste fired operated by Veolia Environmental Services began generating in 1994 – but only in power-only mode. Heat offtake opportunities (so the plant can finally operate in true-CHP mode) are currently being explored with Southwark Council.
