CHP in Universities – Free Seminar
September 2012: The Combined Heat and Power Association (CHPA) and the Carbon Trust are running a free seminar for university and higher education energy managers to discuss the benefits and practicalities involved in CHP, district heating and trigeneration technologies. The all day event will be held on 5 October 2012 at SOAS, University of London, Russell Square, London , WC1H 0XG. Full details on the event and how to book here.
Latest CHP data for London paints confusing picture…
27 September 2012: DECC’s latest issue of Energy Trends follows up from national Combined Heat and Power (CHP) dataset, published in July’s Digest of UK Energy Statistics (Chapter 7) (see also CHPA’s press release for further information on this), to present the data in a regional format, providing some detail on the use of CHP in London. The article – Combined Heat and Power in Scotland, Wales, Northern Ireland and the regions of England in 2011 – can be downloaded here.
A number of things can be observed.
Table 1 highlights that there are 212 CHP schemes in London currently registered with the Government’s CHP Quality Assurance programme (more details at www.chpqa.com). This means that these generation plant have provided details of their operation to the QA programme and qualify for the benefits of being classed as ‘good quality’ such as exemption from the Climate Change Levy. A full list of where these 212 schemes are not unfortunately in the public domain, however, DECC do keep a subset of these schemes (32 listed at the time of writing) on their CHP database (run the region report for London). Additional schemes should also be able to be identified on the London Heat Map. Note – there are likely to be more than 212 schemes – small scale (say around 100kWe and below) CHP engines may not bother registering with the CHPQA as the financial benefits of the CCL exemption may only be modest for such plant.
409 GWh of electricity were produced by these 212 CHP schemes in 2011. This represented 1.8% of the total CHP-electricity generated in England, and only 1.5% of electricity generated in the UK.
Table 2 however appears to show that, since 2009, there has been a net growth of 50 CHP schemes in London (ie some CHP plant may have been decommissioned – the actual number of new plant isn’t provided – only the net figure of 50). There has been a considerable revision of the numbers since last year’s dataset (for which, see story here) which reported that 188 Good Quality CHP schemes were operational in London as at the end of 2010, as compared with the 158 seen in the table above. Overall a confusing picture!
More importantly, there appears to have been a massive downward revision in the overall CHP capacity operating in London:
- Last year’s article indicated that there was 185 MWe (electrical capacity) of CHP operating in London in 2010. In contrast, the revised numbers today state only 122 MWe for the same year (2010).
- The latest data now reports that only 126MWe of CHP electrical generating capacity in London in 2011.
- Hence, whilst this latest data indicates a 4MWe increase in 2011 compared to 2010 all previous reports have indicated that approximately 200MWe of CHP capacity operated in London. Hence, this latest data suggests that there is in fact far less CHP operational in London than previously thought leading to a considerable downward revision!
- The 2011 statistics also report that this 126 MWe of CHP produced 409 GWh of electricity and 1,074 of heat GWh heat – a total of 1,483GWh energy in total – a drop by almost 50% of what we thought CHP was generating in London in terms of heat and power up to today as a result of previous DECC datasets.
- All in all, this does little to help the achievement of London’s 2025 25 per cent decentralised energy target – which is estimated in the Mayor’s Climate and Energy Strategy as a total of 23,500 GWh of energy [p86 – see chapter 4 of the Strategy for further information].
‘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 Thames 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 Thames and use it to heat the estate. A 132-foot glass accumulator tower was built to store extra heat until it was needed.”

Sutton Zero Carbon Resources
June 2012: The results of a project undertaken to help define a zero carbon retrofit strategy for buildings within the suburb of Hackbridge in the London Borough of Sutton has recently been published. The project was undertaken by BioRegional, with funding from the Sainsbury’s Family Charitable Trusts’ Climate Change Collaboration and the three key outputs – the authors say – have been “designed to be replicable in other areas.We hope that you will find them useful for your own projects.”
The area based strategy for zero carbon buildings report seeks to determine:
- How many and what type of buildings would need to be retrofitted.
- What different approaches could be taken to retrofitting, e.g. energy efficiency, building integrated renewable energy technologies or district heating.
- What would be the cost and delivery plan for the preferred approach, which may encompass a range of technologies.
- To develop an approach for formulating a zero carbon strategy for an area that other organisations, such as Local Authorities, Housing Associations and community groups could adopt.
The Retrofitting District Heating Systems study interestingly found that “district heating (using a variety of heat sources) achieved considerably more carbon emission savings than the full traditional retrofit option (whereby a building’s energy efficiency is improved by improving the building fabric and installing energy efficient or renewable sources of heat and electricity in the building itself) and at a lower cost.” A heat map for Hackbridge has also been produced.
And finally, an Energy retrofit tool for buildings spreadsheet tool which allows users to “input information about the domestic building stock in your area and the tool will then help decide on the best approach to retrofitting it using an area-wide approach.”

Map of London District Heating Schemes
June 2012: The London Heat Map captures a lot of the data related to Combined Heat and Power (CHP) and district heating schemes operating in the capital, but the CHPA have added a welcome web resource – a map of UK district heating schemes which includes a good number of London schemes. DECC also provides a list of CHP schemes operating in London – it’s not comprehensive however as operators are not required to have their details listed. Hence, only 32 schemes are listed on the DECC Public CHP database of the 188 schemes DECC state are operating in London in their latest regional CHP statistics.

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.

Vauxhall Nine Elms Battersea Energy Strategy
April 2012: A planning framework for the Vauxhall / Nine Elms / Battersea Opportunity Area has been finalised and is being adopted as Supplementary Planning Guidance to the London Plan. The OAPF has been produced by the GLA in collaboration with Lambeth and Wandsworth councils, as well as TfL and English Heritage and followed a public consultation process that took place in the winter of 2009/10.
The framework sets out an ambition for around 16,000 new homes and a range of 20,000 – 25,0000 jobs and includes the creation of a Combined Cooling and Heat Power network. The technical appendices to the planning framework includes a Energy Strategy Masterplan (TA5) which states that “this report finds that the density and diversity of development in the Vauxhall Nine Elms Battersea (VNEB) Opportunity Area (OA) supports a strong case for the development of a low carbon district heating network (DHN). The scheme would supply low carbon heat to developments in the heart of Nine Elms, Battersea Power Station (BPS) and the New Covent Garden Market (NCGM) initially, with the potential to expand north into Albert Embankment and to the more industrial areas of the OA to the west in the future. It is estimated that such a scheme could save in the order of 18,000 tonnes CO2 per annum, with heat being derived from a combination of low/zero carbon sources,including combined heat and power (CHP) plant burning a blend of natural and renewable biogas and heat from a biomass hot water boiler.” Further detail and download energy appendix here.

New National Policy Planning Framework Launched
March 2012: The Government has released its final version of its National Policy Planning Framework (NPPF) which has gone someway from the initial draft in addressing concerns over the absence of guidance to planning authorities on supporting the development of low carbon and renewable initiatives (as highlighted in an earlier article). The new requirements as set out in the NPPF are welcome – and copied below for information – but are far and away from the detailed guidance that was proposed to be introduced prior to the 2010 election on climate mitigation issues.
National Planning Policy Framework
Included within the 12 ‘core planning principles’ is:
- support the transition to a low carbon future in a changing climate, … encourage the reuse of existing resources, including conversion of existing buildings, and encourage the use of renewable resources (for example, by the development of renewable energy);
93. Planning plays a key role in helping shape places to secure radical reductions in greenhouse gas emissions, minimising vulnerability and providing resilience to the impacts of climate change, and supporting the delivery of renewable and low carbon energy and associated infrastructure. This is central to the economic, social and environmental dimensions of sustainable development.
95. To support the move to a low carbon future, local planning authorities should:
- plan for new development in locations and ways which reduce greenhouse gas emissions;
- actively support energy efficiency improvements to existing buildings; and
- when setting any local requirement for a building’s sustainability, do so in a way consistent with the Government’s zero carbon buildings policy and adopt nationally described standards.
96. In determining planning applications, local planning authorities should expect new development to:
- comply with adopted Local Plan policies on local requirements for decentralised energy supply unless it can be demonstrated by the applicant, having regard to the type of development involved and its design, that this is not feasible or viable; and
- take account of landform, layout, building orientation, massing and landscaping to minimise energy consumption.
97. To help increase the use and supply of renewable and low carbon energy, local planning authorities should recognise the responsibility on all communities to contribute to energy generation from renewable or low carbon sources. They should:
- have a positive strategy to promote energy from renewable and low carbon sources;
- design their policies to maximise renewable and low carbon energy development while ensuring that adverse impacts are addressed satisfactorily, including cumulative landscape and visual impacts;
- consider identifying suitable areas for renewable and low carbon energy sources, and supporting infrastructure, where this would help secure the development of such sources;
- support community-led initiatives for renewable and low carbon energy, including developments outside such areas being taken forward through neighbourhood planning; and
- identify opportunities where development can draw its energy supply from decentralised, renewable or low carbon energy supply systems and for co-locating potential heat customers and suppliers.
98. When determining planning applications, local planning authorities should:
- not require applicants for energy development to demonstrate the overall need for renewable or low carbon energy and also recognise that even small-scale projects provide a valuable contribution to cutting greenhouse gas emissions; and
- approve the application if its impacts are (or can be made) acceptable. Once suitable areas for renewable and low carbon energy have been identified in plans, local planning authorities should also expect subsequent applications for commercial scale projects outside these areas to demonstrate that the proposed location meets the criteria used in identifying suitable areas.
156. Local planning authorities should set out the strategic priorities for the areain the Local Plan. This should include strategic policies to deliver:
- the provision of infrastructure for transport, telecommunications, waste management, water supply, wastewater, flood risk and coastal change management, and the provision of minerals and energy (including heat);
162. Local planning authorities should work with other authorities and providers to:
- assess the quality and capacity of infrastructure for transport, water supply,wastewater and its treatment, energy (including heat)…
IEA: Now is the time for global deployment of smart communities
March 2012: Even the International Energy Agency (IEA) is now highlighting the potential of localised, decentralised energy systems, with the Deputy Executive Director recently stating that “Smart communities – cities, towns, neighbourhoods and villages that reduce their energy demand and generate their own power from renewable sources – should play an increasingly important role across the world…A smart community is a very low energy demand community that integrates several energy supply systems – such as wind, solar and other renewable energy sources. Smart communities effectively reduce energy demand by implementing energy efficiency and energy sufficiency measures. Primary energy demand for a building in a smart community is around a third of the energy demand in the average US household and almost a half of the energy demand in the average household in the European Union.”
Olympic Park – Cutting carbon
March 2012: A briefing event by the IET (Institution of Engineering & Technology) onthe ODA’s approach to “delivering this energy strategy for the Olympic Park, including energy efficient design, the combined cooling heat and power system and renewable energy” with a focus on the district heating network across the site. The event is to take place on 12 March 2012 at the IET London HQ at Savoy Place. Further details and link to book a place here.
