energy for london’s datastore provides links to the latest data sets relevant to London (and other regions in most instances) on issues such as energy generation and demand, carbon emissions, housing energy efficiency data, fuel poverty indicators etc.

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.

DECC HECA Research

November 2013: All English local authorities were required to submit an updated Home Energy Conservation study report to DECC by 31 March 2013. An earlier post goes into these requirements in more detail and provides links to the report from those London boroughs who had posted them online on their website.

DECC have now published research summarising around 245 of these reports (see the Excel spreadsheet on the following link) as well as a document providing links to all reports published online. See both here. Only 20 London boroughs reports are however summarised on the spreadsheet. The HECA list states that some London boroughs have still not submitted reports: these appear to be Barking & Dagenham, Brent, Lambeth and Southwark.

It’s unclear if Bexley, Islington and Merton have submitted reports, as no links are listed – though the list does not say explicitly set out that these reports have not been provided: however, their actions are also not summarised on the spreadsheet.

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…

Green Deal by London Parliamentary Constituencies

September 2013: New Green Deal data released by DECC last week (see earlier post for full details) provides for the first time Green Deal assessments undertaken in each parliamentary constituency. It turns out that constituency with the highest number of assessments  was a London one – Poplar and Limehouse. Table 1b of the dataset records assessments over the period January to June 30 2013 for each of the 573 UK constituencies. Poplar and Limehouse reports the highest number with 462 assessments: however another London constituency also records the lowest number – ‘Cities of London & Westminster‘ with only 3. To put these numbers in context, from the dataset it can be calculated that the average number of assessments undertaken to per constituency date is 75.

A full list of London parliamentary constituencies and number of Green Deal assessments taken – from highest to lowest – is provided below.  Continue reading…

London seminar on measuring city GHG emissions

September 2013: C40 Cities and Siemens’ Infrastructure & Cities sector held a breakfast seminar in London earlier this month on methods to help improve the measurement of city greenhouse gas emissions. A C40 blog sets out discussions held on the day, which focussed around the Pilot Global Protocol for Community-Scale Greenhouse Gas Emissions. Further information on work taken to date on this initiative with 33 cities is posted at the World Resources Initiative (WRI) and full detail on the design of the tool is on the the GHG protocol website.

London has had an inventory in place for around a decade. The latest London Energy and Greenhouse Gas Inventory (LEGGI) was updated for 2011 data just over a month ago and is posted on the London Datastore – details of which are in an earlier post here.

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.

London & the Green Deal: An initial assessment

July 2013: DECC issued the first set of detailed quarterly Green Deal Statistics last week which provide include some limited regional results on the roll-out of the Government’s flagship energy efficiency programme. Hence, a picture of the activity in London to date is beginning to emerge. A number of information releases were published simultaneously on June 27  and are set out below, along with points to note for the capital:

  • The data provided is for the Q1 2013 and hence only covers activity up to 31 March 2013. By that time, 9,294 Green Deal assessments had been undertaken in England. The press release issued on June 27 advises that the latest number of assessments carried out is 38,259.
  • 10% of these 9,294 assessments were undertaken in London (set out in Table 1 on p12 of the statistical news release)
  • An accompanying data spreadsheet provides a local authority breakdown of assessments undertaken. Southwark and Haringey observed the highest level of assessments  in London over the first quarter, with 105 and 100 assessments respectively. Kensington & Chelsea, and the City of London the lowest with 1 and zero respectively. A ‘league table’ of London boroughs is provided below
  • London boroughs (including the GLA) was awarded a total of £925,000 under DECC’s Green Deal Pioneer Places programme earlier this year. See earlier post for details. Consequently, a number of local authorities were providing Green Deal assessments to their residents free of charge. These offers ran up to May for some local authorities, hence assessment numbers for Q1 and Q2 will be boosted by the fact that homeowners are broadly having these services provided free over this period.
  • The DECC data spreadsheet also provides detail on houses assessed (type of home, energy efficiency rating of home) and the measures recommended in the assessment. Though useful, this data does not provide any real indication of how many homes will be eventually install energy efficiency measures. DECC’s press release has Minister Greg Barker stating that “78 per cent of people who have received a Green Deal Advice Report, following a Green Deal assessment, said they had, were getting or would get energy saving measures installed.”
  • In the run-up to the launch of the Green Deal and Energy Company Obligation (ECO), Government recognised that London had not received its fair share of funding from the energy supplier obligations in the past, however, they decided not to establish a  London-specific ECO target as they were of the view that London should benefit under ECO as the programme is strongly focussed on the installation of solid wall insulation (SWI) and London has a large percentage of such homes. A real measure of success in the future will hence be the number of SWI installs in the capital. The latest Green Deal & ECO monthly statistics – issued alongside the quarterly statistics – highlight that 1,565 SWI installs were completed over the first quarter of 2013 across the UK. This is at a far lower rate than previous quarters in previous years (see quarterly progress of SWI in Table 1 of DECC Estimates of Home Insulation Levels in Great Britain – released alongside the GD/ECO statistics). Unfortunately, neither the monthly or quarterly statistics provide a regional breakdown of where these installations took place. This is something DECC will need to provide to help better understand if the ECO is being delivered in London.
  • The Green Deal Cash Back offer, an initial ‘sweetener’ offered by Government on a first come – first served basis, has a pot of £125m. The quarterly statistics for vouchers issued by Government actually go beyond the first quarter – to 16 June 2013 – and show that £263k has so far been awarded. Unfortunately, no regional breakdown has been provided of where these vouchers have been awarded.

So, early days as yet for both the Green Deal and the ECO. More detailed data would be helpful to determine the progress of the programmes in London and elsewhere. It will be interesting to see the Mayor’s response to the Green Deal after an assessment is completed for his own home.

Green Deal assessments by borough are provided below and have been re-ordered from that provided in the quarterly spreadsheet into a ‘league table’ order.

London CRC Performance

April 2013: The Carbon Reduction Commitment (CRC) Performance Table was published a few weeks ago and attracted some media attention on who had gone up and down the table (see Guardian article here). The CRC is a complex mechanism and Government has had to return to tweak the policy time and again to simplify it. Along with the performance table, it appears the Chancellor’s view of simplification is, as set out in his Autumn Statement (December 2012), to get rid of the CRC altogether.

“1.127 The CRC’s Performance League Table will be abolished, to simplify the scheme further. A full review of the effectiveness of the CRC will be held in 2016 and the tax will be a high priority for removal when the public finances allow.”

For those new to the CRC, they should be made aware the original plan of the policy was to recycle the funds obtained from participants purchase of carbon permits, into sector-wide energy efficiency funding. The incoming Government however changed plans in 2010 and the Chancellor simply took all the funds into Government. It’s more than likely the Government would like to see the back of the CRC sooner, however, it does bring in close to £1bn to the Exchequer a year and this will increase again, as  the 2012 Autumn Budget highlights:  “2.88 The forecast allowance price remains unchanged at £12 per tonne of carbon dioxide in 2013-14 and £16 per tonne of carbon dioxide in 2014-15. From 2015-16 onwards, the allowance price will increase in line with the RPI.”

Back to the performance table: how did London do?

4MW of PV added in London

March 2013: Ofgem’s new FIT quarterly report provides an update on the take-up of Feed in Tariff eligible technologies across the UK. London (as at 31 December 2012) has a total of 39.38 MW of FIT renewable capacity installed – as with the rest of the country, the vast proportion of this capacity is made up of PV (99% in London).  This is an increase of 4.25 MW of capacity over the previous quarter.

Progress remains slow in London which  – with the North East – trails all other UK regions by a significant margin. See graph from FIT report below highlighting the number of installations by region.

Previous posts discuss London’s slow performance on FIT take up here.

London SME retrofit programme details

15 March 2013: Details have been released that funding has been approved by the Mayor for a energy efficiency  programme targeted at London’s  small and medium enterprises (SMEs). The approval form sets out that “up to £21,000 will be allocated to commission work to deliver energy efficiency retrofit services. The project seeks to develop SME engagement, improve knowledge of the SME retrofit landscape, and establish suitable financial and delivery models using learning gained from the RE:FIT and RE:NEW programmes, with work to be completed by end-March 2013”.

The Mayor’s 2011 energy strategy set out findings that:

  • small and medium enterprises (SMEs) are reluctant to take action on installing energy efficiency measures and low and zero-carbon microgeneration technologies without seeing that government is taking action on it first (see para 2 or research here)
  • There are currently over 830,000 SMEs in the capital and collectively SMEs emit 20 per cent of the UK’s total CO2 emissions. Due to their size, SMEs  often do not have sufficient resources and expertise to allocate to energy management, and therefore require support and advice to reduce their energy use.
  • However, it is also often hard to reach SMEs and much of the support or drivers through legislation and other programmes are geared towards large organisations (SME data can be found here and here)

And set out the following action:

  • Action 8.5 – The Mayor will support SMEs to reduce their energy use by working with partners and using his programmes to signpost SMEs to existing sources of energy efficiency support. The Mayor will also review the provision of energy efficiency support to SMEs in London, identifying areas where further action is required, and developing support in areas where the Mayor can contribute to its quality, availability and accessibility.

The approval form concludes:

“This work would directly feed into a paper submitted to the Housing Investment Group for approval of GLA funding and resources to deliver pilot projects in 2013-14, and develop a pan-London SME programme. It is currently anticipated that procurement for the full programme would be commenced from 2014, with a full roll-out from 2015 onwards.”

Hence any pan-London programme would, if approved, fully start under a new Mayor after the next London election.
