Overview of CHP data

July 2014: CHP schemes – depending on size and fuel type – can benefit from a variety of government support mechanisms. These mostly take the form of partial exemptions from the Climate Change Levy, the  Carbon Reduction Commitment (CRC), Carbon Floor Price, EU Emissions Trading Scheme, and business rates. Interaction with these mechanisms can be pretty complex at times  (an  overview of these are provided in the following presentations from an industry workshop last December) but critical to attaining these benefits is for the CHP scheme to achieve a ‘Good Quality’ status under the government’s CHPQA programme.

The CHPQA Standard highlights that the QA system has been place since around April 2001 providing  “a methodology for assessing the quality of CHP Schemes in terms of their energy efficiency and environmental performance. This methodology is based on Threshold Criteria, which must be met or exceeded in order for the whole of the Scheme to qualify as ‘Good Quality’.” The QA programme also requires an annual submission from each CHP plant wishing to be classed as ‘Good Quality’ – and details on how to comply with this QA standard are set out in some comprehensive guidance notes posted on DECC’s CHPQA microsite here.

The CHPQA admits that “achieving CHPQA Certification may at first glance appear daunting” but fortunately, for the majority of schemes going forward in London (ie smaller scale), can access a more streamlined QA process which is available for <2MWe CHP plant (see guidance note 13). Overall, CHP schemes can be seen to go through some of the most rigorous monitoring requirements of all sustainable energy measures to receive government support.

CHP schemes in London that have achieved the CHPQA standard – and which have given consent for their details to be released – are listed on DECC’s Public CHP database here (set ‘region’ criteria to London). Aggregate CHP statistics are published in DECC’s Digest of UK Energy Statistics and regional (including London) data in the September issue of DECC’s Energy Trends journal. Further data can also be accessed on Ofgem’s CCL CHP register here. Additional detail on CHP and district heating schemes can be found on the London Heat Map.

Joining the dots…

March 2014: CIBSE article on CHP and district heating in London “With the Government and planners keen for developers to look at district heating for communal heating schemes, the technology is on the up and up. But size matters with heat networks are are some schemes too small to reap the benefits?”  Good article – raising some real concerns over what technical and financial concerns should be considered when pushing district heating – with contributions from the GLA and Islington Council: read the full article here.

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.

Fuel Cells in London

November 2013: The Guardian highlighted in a recent story that the London HQ of Al Gore’s business is to be based in a new office development on Regent Street which has included a wide array of onsite energy measures installed including a gas-powered fuel cell.

“Climate campaigner and former US vice-president Gore said the £400m Quadrant 3 redevelopment showed a “sophisticated commitment to sustainability”. The headquarters of his sustainable investment company, Generation Investment Management, will be sited in the new buildings.

“The cell was developed by US company FuelCell Energy. It will emit 38% less carbon dioxide than using electricity from the grid and heat from gas-fired boilers, according to the crown estate, which says 350 tonnes of carbon dioxide emissions will be saved per year. Unlike fossil-fuel-burning power plants, the fuel cell produces power with virtually no nitrogen oxide (NOx), sulphur dioxide (SOx) or particulate matter (PM) pollution.
The new plant forms part of the central energy system that serves 500,000 sq ft of offices, shops, flats, restaurants and hotels in the Quadrant development.” Read the full Guardian story here.

Further detail on the installation of the fuel cell can be read here – which has been undertaken by Edinburgh based Logan Energy. The Quadrant 3 development has a number of other onsite energy measures installed (including a Combined Cooling Heat & Power plant, thermal stores and photovoltaics – see diagram below), as set out in the property brochure.

Another new London development to include fuel cell technology is that on 20 Fenchurch Street (more commonly known as the ‘Walkie Talkie’ building) which has installed a 300 kWe fuel cell, details of which can be read here and here.

Transport for London installed a fuel cell CHP in their Palestra building in Southwark back in 2010, details of which – including a video presentation – can be seen here and here.

GLA responds to Heat Enquiry

November 2013: The House of Commons Energy and Climate Change Select Committee is currently undertaking an enquiry into Heat. The terms of reference to the enquiry states that “so far much of government’s energy policy focus has been on low-carbon electricity generation (in particular, the Energy Bill, which aims to reform the electricity market).  Yet heat is responsible for 46% of UK energy use, approximately a third of UK greenhouse gas emissions, and is a major cost in both the domestic and non-domestic sectors.”

The Greater London Authority (GLA) has submitted written evidence to the Committee outlining the significant decentralised energy programme underway in the capital. The evidence sets out a number of interesting points related to the wider scale deployment of heat networks as well as recommendations to Government in terms of its policies to promote decentralised generation. These include:

  • The Mayor welcomes the Committee’s scrutiny of this often over-looked area of energy policy
  • There are “inconsistencies in government’s energy policy and regulatory regime that are preventing heat generation and distribution in citieswhich “…distort the market for heat by providing external financial support for some technologies, while largely ignoring heat networks.
  • Heat network deployment at the scale envisaged for London represents a significant infrastructural challenge, requiring approximately 3,600km of heat networks to be constructed by 2030 and equates to an investment opportunity of approximately £6bn
  • Whilst district heating schemes can qualify for funding under ECO, the current two year target as well as uncertainty regarding longer-term target discourage energy suppliers from investing in these schemes.  Government should consider setting longer term targets for the next phases of ECO, or provide guidance on how investment in district heating schemes can contribute to current or future targets
  • We estimate that London housing development will generate at the very least £25m per annum under the proposed Allowable Solutions regime – by far the greatest amount of any region. Yet, because measures are likely to be cheaper outside London, London businesses and households will again be subsidising other regions and receiving less investment into low carbon, heating bill reducing measures. In addition, as Allowable Solutions investment is likely to lever ECO investment, there is a risk that the proposed scheme will exacerbate the imbalance in ECO investment away from London.

The Committee’s evidence gathering process continues in November – more of which can be found here.

Rundown on CHP in London

October 2013: Two recent sources issued by DECC provide data on the use uf Combined Heat and Power (CHP) plant in London. A useful article in DECC’s latest issue of Energy Trends provides a breakdown of CHP use in the regions, providing number of schemes, output, capacity installed and much more. Table 2 from the article is reproduced below.

The data shows a significant increase in the number of CHP schemes operating in London over the past two years (147 – 255) – a 73% jump – whilst generation capacity has grown by 29MW, reflecting the typically smaller scale nature (ie <1MWe) of CHP engines being installed in the capital. Of concern however is that Table 2B (below) from the article reveals that, though the capacity level of CHP has increased – the key metric – the output of decentralised lower-carbon heat and power in London – has actually fallen over the past two years. CHP electricity generation has fallen by 1% and heat generation by 2% in 2012 as compared to 2010 numbers. More promisingly however, the statistics indicate that the 2012 levels show a recovery a far steeper decline in output over the period 2010 to 2011 – so hopefully CHP is now ‘on the up’… Continue reading…
