Bunhill Energy Centre Video

December 2012: Islington has posted a really entertaining video on Youtube describing some of the background to the  development of the Bunhill CHP Scheme,  as well as the benefits being delivered to the local community through the provision of lower carbon, affordable, heat and power. The project has taken close to 10 years to come to fruition, and the district heat scheme extends across Finsbury Leisure Centre, Ironmonger Row Baths, and  Stafford Cripps, St Lukes and Redbrick Housing Estates. Do watch if you get a chance!

“The power revolution could soon be moving from dream to reality”

10 August 2016: Welcome to see the Evening Standard today include a major comment piece by Leo Johnson on how “Small-scale projects such as those in Newham, Brixton and Islington give a glimpse of Britain’s energy future”.

Leo highlights three projects in London as signs of how the decentralised energy model is now in the ascendancy, shifting from the “dominant energy model, the centralised production and distribution of fossil fuel-based power through the grid”.

  • “In Newham, for example, the Combined Heat and intelligent Power plant (CHiP) aims to harness the energy from “fatbergs”, the bus-size balls of grease which cost Thames Water an estimated £1 million a month to remove, using teams of trained “flushers” decked out with protective white suits and shovels who descend into London’s Victorian sewer system to hack up the fat. CHiP plans to use the fat instead to power 40,000 homes.” This project is fascinating and received a lot of coverage when first announced back in 2013 – which was covered in some detail in an earlier post here – but not much further information has been forthcoming from the project on their website.
  • “In Brixton, the energy group Repowering is installing solar panels on the rooftops of housing association buildings to lower fuel bills, and is teaming up with Transport for London to introduce “energy gardens” across 50 London Overground sites.” In June of this yearRepowering was awarded a prestigious Ashden Award for their work – a case study and excellent video are posted on the Ashden website here. The Energy Gardens project was covered by ITV news a few weeks ago – see video here – and more can be seen at energygarden.org.uk
  • “At the Bunhill Energy Centre project in Islington, whose second phase was opened by Mayor Sadiq Khan last month, they’re using heat from the Northern line tube to power a thousand homes.” Lots more about Bunhill here.

Leo also highlights some work commissioned by the GLA by  engineers Buro Happold “have estimated that there is enough heat wasted in London alone to power 70 per cent of the city’s energy needs. What’s the potential for growth? Copenhagen provides 98 per cent of its space and water heating through district heating, at 45 per cent of the cost of normal oil heating bills. London’s uptake, better than the one to two per cent national average, is currently just five per cent.”  The 2013 London Secondary Heat study can be downloaded here.

Islington District Heating Planning Guidance Published

July 2016: Islington have recently published new environmental design planning guidance on heat networks: The guidance is released in two parts – with Part 1 giving an overview of the existing and and planned Islington heat networks, as well as an introduction to the principal behind heat networks (referencing the GLA’s 2014 London Heat Network Manual). Part 2 provides technical guidance to developers looking to connect to Islington’s Bunhill heat and power network.

The Council sets out that it is “committed to working with partners to promote and develop decentralised energy (DE) networks, with a particular focus on areas of the borough with the greatest potential for such networks. Existing DE networks within the borough will be protected and their expansion supported. All development will be required to contribute to the development of DE networks, including by connecting to such networks where these exist within the proximity of the development.”

SoS to CHP

7 March 2016: Good to see the Secretary of State for Energy Amber Rudd today visit Islington Council’s Bunhill Combined Heat and Power (CHP) district heating scheme – much more of which can be read about here. The Minister can be seen below being given a tour of the innovative energy centre, sited just off Old Street roundabout, by Islington Council’s Energy Manager, Lucy Padfield.

Bunhill has had lots of visitors since it was opened in 2012 – but – suprisingly the Mayor has not managed to view the project.

Arriving soon… heat from tube line piped straight to your home through £6m energy scheme

8 January 2016:  The Islington Tribune reports that “Building  work on a groundbreaking £6.2million energy scheme which will see waste heat from the Northern tube line piped into homes will start this month. As first revealed in the Tribune last year, the project – the first of its kind in Europe – will harness heat from the underground and help keep energy bills in 500 council homes on the King Square estate in Finsbury up to 10 per cent cheaper.

“This month, work will start on a new, four-storey energy centre at the junction of Moreland Street and City Road, on the east side of Kestrel House, as the Town Hall extends the Bunhill heating pipe network to capture heat from a tube line ventilation shaft. The underground provides access to natural heat stored within the ground. Both the trains and the nearby electrical sub-station produce waste heat, which will be captured and piped to the combined heat-and-power unit in Central Street.”

Decentralised Heat and Power Points to London’s Energy Future

January 2014: Still a few days left to see BBC’s excellent Inside Out London programme. The first half covers the increasing levels of energy theft being observed by energy companies and -18 minutes in – the programme looks at potential future solutions to the provision of more affordable heat and power in London.

The growth in local energy solutions, such as combined heat and power (CHP) plants and the introduction of new district heating schemes are highlighted, including recent projects installed in Islington (Bunhill CHP) and the heat network constructed from the SELCHP waste to energy scheme, which transports low cost heat to 2,500 households in Southwark with an approximate 22% reduction in heating charges.

£67.23m of DE projects to be delivered in London

22 April 2013: A useful update on some of London’s key decentralised energy (DE) projects being supported by the Mayor has been produced for the GLA Investment and Performance Board meeting taking place tomorrow (23 April). The Mayor’s Decentralised Energy Project Delivery Unit (DEPDU) is a three-year programme set up in August 2011 with €3.3m funding, 90% of which was secured from the European Investment Bank’s ELENA facility.

The paper (link to paper, direct here) sets out that the GLA has a contractual target with the EIB to deliver £67.23m of DE projects to market before the 3rd of August 2014.   The following projects as of 31st December 2012 have been taken to market through the GLA’s Decentralised Energy for London programme and, as agreed with the EIB as eligible projects. Together, they represent £42.3m, or 64% of the final ELENA target.

Project Eligible CAPEX (£) Construction completed CO2 savings (t/year) Project stage
Islington Bunhill Phase 1 £6,499,107 2011 2,950 Operational
Cranston Estate £7,800,000 2011 1,200 Operational

The Future of Heating in London

March 2013: The Government’s Future of Heating policy paper released yesterday gives prominent coverage to activities underway in London to promote the use of decentralised energy systems through the use of district heating and high efficiency Combined Heat and Power (CHP) systems. The paper includes the following:

  • A case study of The Shard CHP heat network [p41]
  • How Islington Council, the GLA  and UK Power Networks are working together on “a proposed extension of the existing Bunhill heat network that will capture and use identified sources of waste heat produced within the area, such as from a nearby electricity sub-station. This project will help London and its boroughs to identify, capture and make use of urban sources of waste heat and play an important part in developing their lower carbon, lower temperature heat networks ofthe future” [p43] Continue reading…
