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

CIL supporting sustainable energy in Camden

November 2012: Camden have issued further information on a new Camden Community Infrastructure Levy (CIL) and are asking for views on a preliminary draft charging schedule. The consultation sets out that “The Community Infrastructure Levy (CIL) is a new charge that local authorities will be able to collect on new developments in their area. It is based on a formula relating to the type and size of development and is collected when planning permissions for new developments are implemented. The funds gathered will be spent on infrastructure within Camden such as schools, community facilities, highways improvements and many other forms of provision which are currently funded by monies paid by developers under Section 106 obligations.”

As part of the evidence base required for setting the CIL, Camden have commissioned an infrastructure study examining key utilities required in the borough over the coming decades. This study includes energy infrastructure, with page 47 onwards setting out a useful summary of some key sustainable energy issues for Camden:

“LB Camden recognises that it needs to play its part in supporting London’s drive towards a lower carbon energy supply. Consultation with the Council has indicated that three areas within the borough could form the focal points for public investment – Euston/KingsCross;  Bloomsbury/Tottenham Court Road; and Gospel Oak – with a figure of £1 million for each area (£3m in total) being considered appropriate to help lever in further private investment. To date £3.8 million has been secured from the Francis Crick Institute (national medical research centre next to St Pancras station), although the further £1 million identified through consultation with the council will still be needed to address linking up other major development sites in the Euston/Kings Cross area.”

Appendix A of the report provides some further information. The consultation runs from 8 Nov 2012 to 20 Dec 2012. Further information on decentralised energy opportunities are set out in Camden’s Heat Map (scroll to the bottom of page).

Kings Cross Energy Centre Open Day

31 October 2012: Operators of the Kings Cross Energy Centre, Vital Energi, have announced that they will hold an Open Day and tour of the Centre on November the 22nd. Full details of how to register here. The Energy Centre lies at the heart of  Europe’s largest city centre regeneration scheme with the £2 billion, 67-acre scheme even having its own postcode – N1C. Three gas-fired  CHP engines will provide 7MW of electricity and will supply the bulk of the heat demand onsite – along with a supplementary biomass boiler and thermal heat store (the latter being a big hot water tank!)

For further information see Kings Cross Central’s Energy Centre Explained page and an earlier post which highlights that the “CHP engine will not only generate electricity, which will be fed into the grid network, but will also provide heat for the development wide District Heating System (DHS). All of the 70 buildings at King’s Cross, from the University of Arts to the Camden Council building, BNP Paribas Real Estate’s new offices and the Great Northern Hotel, will be connected to the DHS.”

‘Heating experts’ towering vision’

1 October 2012: The ‘Pimlico District Heating Undertaking (PDHU)’ was one of the many sites available to be viewed by the public on Open House Day over the past weekend.

As CityWest Homes website sets out “PDHU is owned by Westminster City Council and managed by CityWest Homes. It provides clean, safe and reliable energy to approximately 3,200 properties and 56 local businesses. It was the first of its kind in Britain and started life in a pump house using waste heat from Battersea Power Station to provide heating and hot water to one local housing estate.

The system was upgraded in 2006 with a £6.9million boiler plant added to the system which will be able to heat an additional 1,400 homes. This will lead to further savings on nearly 3,000 tonnes of carbon dioxide each year – the equivalent of taking 1,000 cars a year off the roads of London. The upgrade was paid for by the Community Energy Programme. It includes two combined heat and power engines and has been built on the site of the original pump house.”

As a recent Arup research project highlights there are hopes that PDHU could at some time in the near future, connect to the nearby Whitehall District Heating Scheme.

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.

‘The heat under the street’

September 2012: An Inside Housing article providing a brief history of district heating and what London’s emphasis on DH might point to in relation to the Government’s forthcoming heat strategy.

The article highlights that “the mayor of London’s energy team worked with all the boroughs to produce a map of the city’s heat demand and found that heating networks are best suited to dense, urban areas where lots of homes or businesses can be connected without installing lengthy pipes.” These borough heat maps and associated reports are all posted in full on the London Heat Map website.

The article also helpfully details the history and plans for growth of the Pimlico District Heating Undertaken (PDHU). Heat for this system was originally taken from Battersea Power Station, which – until the DH system came into being -simply pumped waste heat into the Thames. The article sets out that “Work began on the north side of the ƒThames on Churchill Gardens, a 1,600-home social housing estate. A savvy decision was made to contain all the waste heat from Battersea Power Station, pump it under the ƒThames and use it to heat the estate. A 132-foot glass accumulator tower was built to store extra heat until it was needed.”

KX CHP

May 2012: The first of  three 2 MW Combined Heat and Power (CHP) engines  for the 67 acre King’s Cross Central development has been installed at the on-site energy centre. In total the CHP capacity when finally installed will supply 100% of the development’s heat and offset almost 80% of its electrical power demand. The news release sets out that “Once commissioned, the CHP engine will not only generate electricity, which will be fed into the grid network, but will also provide heat for the development wide District Heating System (DHS). All of the 70 buildings at King’s Cross, from the University of Arts to the Camden Council building, BNP Paribas Real Estate’s new offices and the Great Northern Hotel, will be connected to the DHS When complete carbon emissions are expected to be a third less than ‘business as usual’ and up to 60% less than 2001 levels.”

Further information on the energy strategy for Kings Cross central here and main energy assessment (as set out for the planning application in 2005) can be downloaded here.

South Kilburn decentralised energy system

February 2012: Brent Council has recently issued a tender for a major new decentralised energy heat and power system in South Kilburn. The tender outlines that “It is envisaged that c. 2 000 new homes, a new school, a healthy living centre and new commercial units will be built in the area. This site will have a high proportion of new build, medium rise social housing blocks and as such is well suited to a heat network. London Borough of Brent is procuring the services of an energy service company to finance, design, build, manage and maintain a decentralised energy system which will provide heat with a combination of CHP and boilers to the new residential and non-residential units for a period of 40 years.”

The Council is looking to a company to install the necessary infrastructure including heat pipes to establish a linked network and to distribute the heat to each building via the network. The investment required to realise the scheme is estimated by the Council to be of the order of £67m.

Additional information on the project including a timeline for the approval for the contract are provided in the following Brent Council document.
