Enfield Gasification Scheme

Posted on November 21, 2011 by Admin

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

Posted on October 13, 2011 by Admin

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

Posted on August 9, 2011 by Admin

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

Posted on July 30, 2011 by Admin

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.

Recycling Cooking Oil in London

Posted on July 28, 2011 by Admin

July 2011: The Committee on Climate Change are currently undertaking a review of bioenergy and took a trip to have a look at the work of Uptown Oil who  collect used cooking oil from about a thousand sources in London – including Young’s pubs, Selfridges and Hackney Borough Council – to produce biodiesel.
A Business Green article published last week highlighted that Carluccio’s Restaurant chain – which has around 20 cafes in London – announced that it has signed a deal with biofuel firm Convert2Green to be converted into biofuel.  Other biofuel suppliers in London include:
Uptown Oil based in Borough
Pure Fuels based in Edmonton
Proper Oils who work with a  Croydon Council collection scheme
Uptown have also been selected to supply biofuel to PWC’s new HQ whose energy will be partially supplied by a trigeneration scheme (combined heat and power with cooling) – one of London’s only biofuelled CHP schemes.
Figures for the amount of cooking oil collected in London and be turned into biofuel do not appear to be available, however, a study reported on by the London Assembly in 2009 indicated that 37,000 tonnes of used cooking oil is available in London and the DfT’s latest biofuel statistics state that the “largest single feedstock for UK biofuel was used cooking oil (314m litres, 26% of total biofuel supplied)“. London’s Draft Waste Municipal Waste Strategy commits that the “Mayor will, through his Food to Fuel Alliance, aim to catalyse at least five exemplar food waste projects in London…the Alliance will support food waste projects that generate renewable heat and power (including transport fuel), and compost material for local use.”
