Data Store

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.

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!

London energy data maps

January 2013: Tim Starley Grainger has posted some useful graphics on how London is faring under some key Government energy efficiency and renewable energy programmes, such as CERT, Warm Front and progress under the Feed in Tariffs (FITs). As highlighted in various posts on this site, it doesn’t make for cheerful viewing. Graphics posted here.

The Electric City

December 2012: Following last week’s LSE Cities ‘Electric City’ conference which took place at the fascinating ‘Former Shoreditch Electricity Generating Station & Refuse Destructor’ some material have been posted online.

  • A series of essays on the theme Electric City have been brought together in a publication for the conference which can be downloaded here. There’s not much specifically on London’s energy challenges, but the Global Problems: City Solutions contribution highlights an interesting point suggesting that “According to some reports, urban regions already produce ten times more renewable technologies patents than rural regions.”
  • A selection of video interviews from the conference are posted on Youtube
  • And the Guardian has posted a series of ‘exclusive data visualisations’ from the conference which includes ‘Unpacking London: energy & pollution’ highlighting that “Three quarters of London’s energy consumption is fueled directly by oil and gas, with the vast majority of the remainder generated by fossil-fuel-powered electricity. Just 2.1% comes either direct from waste and renewables or from renewably-generated electricity.”

Waltham Forest has highest number of PV installations of any London borough

24 October 2012: A recent post provided some regional detail of the uptake of Feed in Tariff (FITs) generators – predominantly photovoltaics (PVs) – across the UK (at the English regions and devolved administrations level). DECC have today released an updated spreadsheet providing a breakdown on the number of installations at local authority and parliamentary constituency level. This highlights that:

  • London’s suburbs do the best in relation to PVs installed with Waltham Forest  having the highest number of installs of all London boroughs (701); then Bromley (666), Croydon (525)  and Havering (440).
  • The parliamentary constituency of Walthamstow has accordingly the highest number of PV installations of any constituency in London (373). [For context, Tiverton in Devon has the highest number of installations of any UK constituency – 2,456]
  • Unfortunately installed capacity (ie kWe of generation) by local authority/constituency is not available – which would be a more helpful metric (it is included available on a per installation basis in Ofgem’s comprehensive FIT spreadsheet (370k+ entries) – the latest of which was published a few weeks ago – and which Energy for London is currently going through and will report on shortly).
  • A not very helpful map is also provided by DECC today of Number of domestic photovoltaic installations by Local Authority, as at end of September 2012

In addition to the direct link here the spreadsheet can also be downloaded from the following DECC FITs webpage (the file is called ‘Sub-regional Feed-in Tariffs confirmed on the CFR statistics‘).

Carbon Visualisation

October 2012: A previous post highlighted how a campaign by the excellent Centre for Sustainable Energy managed to secure the release of a 40,000 dataset of public sector buildings Display Energy Certificates (DECs).

CSE have recently highlighted how this data has been used by a company called Carbon Visuals.

Some of the London building carbon data is illustrated above.

Carbon Visuals explain:
“With a grant from the UK’s Technology Strategy Board we have been exploring real-time visualisation and the visualisation of large data-sets. One of the results is an interactive visualisation of the carbon footprint of every public building in England and Wales – 40 thousand of them! The visualisation works in any browser that can run the Google Earth plugin but because the dataset is large, the plugin may perform sluggishly on slow computers. Or open in desktop version of Google Earth:

Statistics on new housing starts and completions in each local authority in London

September 2012: Recent parliamentary question in the House of Commons provides a useful summary on where London housing statistics are kept and collated.

Statistics on new housing starts and completions in each local authority in London, taken from the National Statistics on House Building, are published in live table 253 on the Department for Communities and Local Government’s website which is available on the following link.

These statistics show starts and completions split by tenure according to whether the organisation responsible for the development is a private company, a housing association or a local authority. The figures for housing associations and local authorities can together be used as a proxy for affordable housing starts and completions. However, these figures may underestimate affordable housing supply and overestimate private housing, as they are from building control records in which the ultimate tenure may be difficult to identify.

Statistics on the full extent of affordable housing supply by local authority are published in the Department’s live tables 1006, 1007 and 1008, which are available at the following link.

From 1 April 2012, the Mayor of London has had oversight of strategic housing, regeneration and economic development in London.

Mass-retrofitting of a low carbon zone

June 2012 A very detailed piece of analysis undertaken by researchers at Edinburgh University (and published in the June issue of academic journal Energy Policy) which studies the work being undertaken in Sutton on adopting an area wide retrofit scheme in Hackbridge.

The conclusions highlight some really interesting findings relating to Hackbridge  which are also very relevant to other areas of London. These include:

  • housing built pre-1918 on average consumes 56% more energy and emits 41% more CO2 than houses built post-2001;
  • the older housing stock is the worst performer in terms of energy efficiency; the most laborious and costly to improve;
  • within the regeneration footprint, this type of housing makes up less than 20% of the housing stock. Nearly 40% of the housing stock having been built post-1970 is already benefitting from many of the measures proposed to save energy and reduce carbon emissions;
  • almost one third of Hackbridge residents live in areas which rank within the top 25% most income-deprived in England, renting their homes from the Local Authority, Registered Social Landlords, Housing Associations or the private-rented sector. Homes in the social-rented sector that have been shown to consume less energy and to emit less CO2 than other housing types of a similar age in Hackbridge. Indeed, using the Government’s Standard Assessment Procedure for the energy rating of dwellings (SAP), the local authority housing in question is shown to out-perform the national average ratings across all dwelling types.

The study also includes: “…while policy analysis over the past decade has done much to highlight the potential contribution mass retrofits in the housing sector can make to reduce the rates of energy consumption and levels of carbon emissions, they also serve to illustrate how little is currently known about the institutional arrangements towns and cities are currently putting in place as integrated solutions to the problems climate change pose.

Unusually for Energy Policy, the article full downloadable free of charge here.

Heat Maps produced for every London borough

June 2012: The London Heat Map project has now posted online heat map reports and datasets for every London borough. Information provided sets out that “The new heat maps are higher resolution with real heat consumption data for priority buildings such as hospitals, leisure centres and local authority buildings. As part of this work, each of the boroughs has developed implementation plans to help them take the decentralised energy opportunities identified to the next stages. The implementation plans include barriers and opportunities, actions to be taken by the council, key dates, personnel responsible.”
