Latest London PV statistics

August 2016: The last set of sub regional Feed in Tariff (FIT) statistics published by DECC – before it is merged with the business department into BEIS – were published last week (available here). London PV data – alongside other UK regions – is reproduced below.

Table 1. Cumulative installations confirmed on the Central Feed-in Tariff Register by Region

Table 2. Cumulative capacity confirmed on the Central Feed-in Tariff Register by Region

So – as at the end of June 2016:

  • London had 20,551 PV installations (95% of which were domestic installations) with a total combined electrical generating capacity of 83.911MW.
  • London’s capacity represented just 2% of total UK PV generating capacity
  • The last FIT quarterly data set (for data up to the end of March 2016) reported that London had 20,123 PV installations in London and 81.623 MW – indicating a 2.28MW increase in capacity over the last three months.

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.

Barking & Dagenham most energy efficient local authority in UK

November 2013: A news release from Imperial College highlights a recent study examining the energy consumption of all 198 urban local authorities in the UK, including 33 boroughs in London.  Dr James Keirstead has developed a “new method that draws on three different measures of energy efficiency, currently used by city planners, to create the ranking. The aim was to find the fairest methodology for determining energy efficiency that could give planners an improved way of spotting best practice, leading to more energy efficient and sustainable policies in the future.”

“The London boroughs of Barking and Dagenham and Hackney topped the league table of all UK urban areas analysed in the study…This may be because both are low income areas, equating to lower energy usage. Residents of those areas are also more reliant on public transport and these boroughs lack energy-intensive manufacturing and commerce, which may also be other factors that explain why consumption is lower.”

The news report is a very short summary of a detailed research paper published by Dr Keirstead in technical journal Energy Policy (which unfortunately has a price tag associated with downloading the paper). The table from the paper providing a ranking of UK local authorities by average energy efficiency score is reproduced below:

Other London boroughs within the top 10 are Hackney, Merton, Redbridge and Kingston. Oddly, the top two ranked London councils are both within inner London, however, the remaining three in the 10 are all suburban local authorities.

Local authorities in England have now reported to Government on energy efficiency activities in their area in HECA update reports – for more of which, see 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…

Latest greenhouse gas inventory data for London published

September 2013: The London Datastore has recently posted detailed greenhouse gas emission data for London across a wide range of economic sectors. The spreadsheet for the 2011 update to the London Energy and Greenhouse Gas Inventory (LEGGI) provides estimates of energy consumption and CO2 emissions from Homes, Workplaces and Transport within the Greater London area and is produced by the GLA on an annual basis to measure progress against the Mayor’s Climate Change Mitigation and Energy Strategy.

The Department of Energy and Climate Change (DECC) also provide London emissions data (though not to the level of detail as that set out in the LEGGI) in a series of  sub-regional statistics which can be downloaded here.

Regional Green Deal statistics available …but not quite yet

14 March 2013: DECC published their first statistical release today on activity under the Green Deal over the months of January and February 2013 (statement by Secretary of State here). This revealed that 1,803 assessments of properties have taken place over the two months. The statistics however do not set out where these assessments were undertaken – ie no regional breakdown has been provided – which is hugely disappointing. Hence – the following twitter conversation took place.

So – Green Deal (and ECO also …?) regional statistics (hopefully at the local authority rather simply the regional level) will be made available in the fuller dataset released in June of this year. DECC should also consider reporting on a regional basis in the monthly stats …a discussion that will likely continue. Interested parties do feel free to contact DECC to request this happens!

Electricity Consumption per London Borough

February 2013: London Datastore has posted a cut-down version of DECC’s latest statistics of electricity consumption by local authority providing just the London boroughs detail (use the Excel link provided on the London Datastore webpage). A timeseries of data from 2003-2011 is made available and includes electricity consumption (GWh) per borough for domestic customers and I&C (industrial and commercial) consumers. The table also provides the number of MPANs (Meter Point Administration Number) per borough per domestic/I&C sector. For more on MPANs see the following entry on Wikipedia …and for still more see the following factsheet on Elexon’s website.

Waltham Forest continues to lead on PV

January 2013: DECC have released their latest quarterly dataset of “Sub-regional statistics show [ing] the number of installations and total installed capacity by technology type at the end the latest quarter that have been confirmed on the Central FIT Register (CFR)”. [DECC weblink;  Excel file] The data provides a useful breakdown of installations under the Feed in Tariff (FIT) programme by ‘local authorities’ and also ‘parliamentary constituency’. The top 10  London boroughs by total installs of PV (photovoltaic) installations under the FITs programme (which started in April 2010) is provided below.

Waltham Forest 861
Bromley 730
Croydon 577
Havering 491
Bexley 404
Richmond upon Thames 397
Barnet 394
Ealing 383
Redbridge 336
Lewisham 315

Points to note:

  • Waltham Forest continues to be the local authority with the most number of total PV installs
  • By comparing the latest dataset to the previous October 2012 dataset, it can also be seen that Waltham Forest had the highest number of PV installs over the past quarter (136) – 3-4 times as much as the next nearest boroughs (Bromley (49), Croydon (33) and Havering (32)
  • Over the last three quarters London has seen a small drop in its percentage of total PV installs as a proportion of the UK total – from 2.79% to 2.76%
  • Further comparison of PVs in London compared to other UK regions can be seen here.

New Energy Centre for Energy Epidemiology

January 2013: University College London announced that it has been awarded funding to establish the UCL-Energy Centre for Energy Epidemiology which “will focus on providing an evidence base for government and industry to support end use energy reduction across buildings and transport, helping to deliver the UK’s commitment to reduce greenhouse gas emissions by 80% of 1990 levels by 2050.”  ‘Energy Epidemiology – it says here –  is apparently “the systematic use of measured data to illuminate the causes of energy use and of changes in energy use.  The approach has a long history in health research, but has not so far been applied, at scale, to the study of energy.” So now you know!
