New substation for Islington
10 December 2020: UK Power Networks (UKPN) press release announcing “UK Power Networks has finished work on a new substation which is the key to unlocking extra electrical capacity in Islington and its surrounding areas. It is the first step of UK Power Networks’ strategy for North London, which will mean it can decommission older electricity cabling between Hackney-Holloway-Shoreditch and move into a new era with state-of-the-art equipment for the future. “

Open Data: UK Power Networks
November 2020: An interesting new initiative from London’s (main) distribution network operator UK Power Networks (UKPN) providing “data for the first time, covering three themes: facilitating Net Zero, improving the network and informing strategy.” The initiative responds to the Energy Data Taskforce recommendations made in their 2019 report which highlighted that the energy transition is being impeded by often poor quality, inaccurate, or missing data, while valuable data is often restricted or hard to find.
There’s a lot here – a few quick points of interest to me:
- UK Power Network set out their pathway for opening up data in their Digital Strategy paper from December 2019 – available here
- Under the ‘Network Data’ tab an Embedded Capacity Register is available providing information on generation and storage resources (>1MW) that are connected, or accepted to connect to UKPN’s network. The spreadsheet does not mention the capacity of the asset connected – just the network characteristic the asset is connected to. The address search facility does allow for filtering just for London (UKPN covers the south-east and eastern regions in addition to London) – but does not seem to allow for London borough searches (at least not for all London boroughs). And as the register only lists those assets above 1MW, much of the distribution generation capacity in London isn’t captured here as it is below this level (they can be found through other tools however including the London Heat Map, Ofgem’s CHP register and also Feed in Tariff (FIT) datasets (here and here);
- The ‘Facilitating Net Zero’ tab includes data on: Connecting Distributed Generation; Electric Vehicle Connections in London; Electric Vehicle – Network Capacity and Electric Vehicle Future Constraint Map.
- And an interesting study undertaken by Element Energy for UKPN setting out Distribution Future Network Scenarios along with a large number of interesting forecast datasets of assets that could be connected to the network over the period to 2050.
Much more to explore here – and an important input for London boroughs working on their climate emergency plans. Great to see UKPN make this data available, and I hope they will continue to work with London local authorities to ensure that the datasets work for them.

London’s electricity infrastructure under spotlight
October 2013: The issue of London’s electricity infrastructure is being raised in several quarters now, most recently by the Mayor in a letter to Secretary of State for Energy , Ed Davey, and through the Mayor’s High Level Electricity Working Group. More recently the GLA London Infrastructure Group has looked at future constraints on London’s electricity network, which has led to the recent commissioning of a piece of research work looking at barriers to connection to the electricity distribution network in the capital.
The latest meeting of the Infrastructure Group turns again to this issues, with a short briefing paper (Agenda Item 4 Appendix A) presented for discussion which highlights the following:
“the UK’s poor ranking on electricity connections (only 62nd out of 185 economies) in the World Bank’s ‘Ease of Doing Business’ survey (London example was used for UK assessment), the Prime Minister’s Office and the Department for Business Innovation and Skills (BIS) are now investigating the issue and officers as well as Matthew Pencharz are in touch with relevant officials. ”
In relation to the recently commissioned research the paper states this “is expected to conclude in January/February 2014, and on its basis further discussions with the Government and other key players about improving infrastructure funding arrangements will be initiated.”

Mayor’s concerns over London’s future electricity supply – correspondence with Ed Davey
September 2013: The Mayor’s concerns over “uncertainties of our energy supply and growing chances of supply disruption in the coming years” have been highlighted in correspondence between Boris Johnson and Ed Davey, the Secretary of State for Energy and Climate Change, Ed Davey, released this week.
The Mayor writes that his “priority is delivering the jobs and growth that will ensure London remains the best big city in the world in which we live, work and invest, and having a secure energy supply will be absolutely crucial to achieving this… I am adamant that we must do everything in our power now to ensure that the lights will stay on in the future.”
The Mayor calls for major changes to the regulatory control framework rules for distribution network operators (DNOs). As these are predominantly monopoly businesses, the operating framework is set by energy regulator Ofgem. DNOs are the companies operating the local electricity grid (as opposed to the higher voltage ‘national transmission grid’) and in London the majority of the distribution network is managed by UK Power Networks and parts of west London by Scottish & Southern Energy. The Mayor letter calls for a “urgent review of the currently regulatory regime to ensure that DNOs are able to invest in energy infrastructure and install capacity ahead of need”.
The Mayor highlights problems with current legislation and – interestingly – points to “the way Ofgem interprets and exercises its regulatory functions [which] are not fit for purpose” and finally calls upon the Secretary of State for ideas on how to give “DNOs in London substantially more scope and flexibility to reduce the level of network stress and improve strategic investment in London’s electricity infrastructure.”
In response to the tightening of electricity supply capacity over the next few years Ed Davey refers to possible extensions to existing balancing services operated by National Grid and in the “medium term …steps to ensure sufficient investment in capacity via the Capacity Market, with the first auction taking place in 2014 for 2018/19 delivery.”
On the issue often brought up by businesses – the speed of installing electricity connections to new users – the Minster’s letter touches upon current Ofgem work to set the new electricity distribution price control (called RIIO ED1) and sets out that “the existing framework provides the flexibility to drive efficiency outcomes in the vast majority of cases.”
The Mayor’s correspondence with Ed Davey is set out in Appendix 6a of the following GLA document.
The Mayor has established a ‘High Level Electricity Working Group’ to look at many of the issues raised above and minutes and papers from the three meetings that have taken place to date of this group can be found here. A further recent paper looking at London’s electricity infrastructure by the London Infrastructure Group can be viewed here.

London’s Electricity Infrastructure
July 2013: A recent meeting of the London Infrastructure Group, part of the London Enterprise Panel (the local enterprise partnership for London) included a paper considering requirements for London’s growing electricity infrastructure.
The paper highlights that “UK Power Networks (UKPN) is London’s main Distribution Network Operator (DNO) for electricity serving all except the London boroughs of Hillingdon, Hounslow and Ealing. Scottish and Southern Energy serve these boroughs. As DNO UKPN’s responsibility extends from the Grid Supply Points where it takes electricity at high voltages from National Grid to the supply of London’s homes and businesses.”
UKPN is currently consulting on its 2015 – 2023 Business Plan which is to be submitted to Ofgem. Much of the detail around UKPN’s proposals in the Plan have been discussed in recent meetings of the Mayor’s High Level Electricity Working Group and an appendix paper to the London Infrastructure Group meeting considers some key elements of the Plan.
The papers report that the Mayor has raised concerns regarding future investment in London’s electricity distribution infrastructure and that UKPN latest proposals “represent a step backwards regarding the prospects of UKPN investing in advance of need. It gives rise to concern about whether UKPN has taken sufficiently full account of the needs of the City of London and other central London boroughs facing business and development growth. The reason for the backward step is mainly attributable to the intervention of Ofgem” (some of these concerns on future needs were recently raised by businesses in the recent West End Commission report).
Investment in major substations has been reduced from £170 million to £100 million compared to the original draft. UKPN now includes only four of the planned six (plus Earls Court1) major substations for central London on a funded basis (see Table 1 below for details). The origin of the change is principally Ofgem’s unwillingness to accept the remaining three substations as part of UKPN’s regulated asset base, since they would amount to investment by UKPN in advance of an actual connection being requested.
Interesting to note that other changes have been made to UKPN’s forecasts of sustainable energy investment in response to comments to the original consultation. These include changes to the assumptions regarding the uptake of electric vehicles and to the infrastructure investment for Feed–in–Tariff eligible generation.

Comparing PV in London to other regions
January 2013: With the publication of Ofgem’s new FITs newsletter (Quarterly Report 10 – December 2012 which looks at data up to September 2012) – it’s useful to look at back at the data over the past 10 issues and see how the capital has been faring under the programme with respect to most appropriate of the FIT technologies – photovoltaics (ie PV or solar electric). It should be noted that PV makes up 98% of FIT installations and 90% of total FIT generation capacity installed (see the newsletter for full details).
Previous posts (here and here) have looked at various FIT data sets and highlighted the fact that London has had the lowest capacity of PV installed of any region.
Plotting the installation rates of PV capacity per region per quarter (as provided by data in the Ofgem newsletters) since the FIT programme started (April 2010) provides a comparison of not only how low London’s capacity is compared to other regions of the country (London is the line skirting along the bottom, just below the North-East), but also how the various regions reacted to the sudden and major change in FIT tariffs (a good summary of which is in the following Guardian article).
The majority of regions witnessed a significant’spike’ in the number of PV systems installed as a result of the Government’s announcement that there was to be an near-immediate reduction in the FIT tariff level for PV. However, in London, though there there was an increase – it was incredibly modest compared to nearly all other parts of the country. Does this reflect:
- A low level of interest in PV by Londoners?
- More renters and more flats in London reducing demand for PV?
- Perhaps only a small number of companies are offering PV in the capital?
- Less knowledge in the benefits of PV by Londoners?
- Or are PV companies more attracted to doing business outside London – ie cheaper staff, less hassle factor, easier to put up scaffolding etc etc – more installs mean more money for them?
Whatever the reason, the potential of the most appropriate of the renewable technologies for London is currently being unrealised. The GLA’s 2012 London renewable energy study estimated that PV has the technical potential to supply up to 19% of the capital’s electricity consumption.
NB More recent data – up to December 31 2012 – is available in Ofgem’s latest FIT register database of 8 January 2013 (link to the Excel spreadsheet here – it’s a big file at 39MB with around 350,000 separate entries for FIT installations across the UK). The database indicates that of the 31MW of PV capacity in London, the vast majority – around 27 MW – comes from small scale household installations.

GLA to apply for a ‘junior’ electricity supply licence
29 October 2012: The GLA are apply to the energy regulator Ofgem for a ‘junior or sometimes known as ‘lite ‘ electricity supply licence. This allows for smaller electricity generators to sell their electricity at market value. The approval form sets out that “the application to Ofgem [is] for a licence lite licence so the GLA can buy the electricity produced by London boroughs and other public sector decentralised energy generators in London and sell it at proper market rates”. This project builds on an earlier GLA project (details here).
The background to this issue is actually quite simple but solutions complex! Luckily some helpful commentaries are posted on the web by Carbon Limited and also law firm Nabarros. At the heart of the argument is that smaller generators are often in poor bargaining positions with the electricity retail market when wanting to sell their electricity. The true value of the electricity generated by a decentralised CHP, or PV array, could be realised by selling the electricity direct to consumers (very roughly say, around 12-14 pence per unit) rather than the wholesale market (again roughly, but say 4-6 pence per unit).
However, to do this, an electricity supply licence (for generators exporting more that 2.5 MW) is, in most instances required, and holding such a licence places a number of very complex and costly requirements on the licence holder, effectively creating a barrier to entry for smaller generators in this market. Recognising this situation, Ofgem introduced arrangements for a new ‘lite supply licence’ which – in theory – would allow the holder to sell their electricity more widely but provided exemptions to these smaller generators from the requirement to be involved in a number of complex electricity market processes, as would normally be required under a ‘full’ supply licence conditions (see the ‘Final Proposals document by Ofgem posted here for more on this).
In practice however, though a project with a number of London boroughs looked at this issue earlier this year, no participants have applied to hold such a licence. Hence, with this action, the GLA is looking to test Ofgem’s process and apply for this new licence and support the development and production of decentralised energy supply in London.

Who supplies electricity to Londoners?
11 September 2012: A recent parliamentary question highlights the extent the Londoners continue to use the local energy supply company EDF Energy (who took over London Electricity fully in 2006) as their electricity supplier. The response reports on data from August 2010 and indicates that EDF Energy has a market share of 74% of London’s electricity market. In terms of dual fuel contracts, British Gas holds the largest market share in London across the ‘big six’ at 40%.

Update on London Power Tunnels project
May 2012: An update on the London tunnelling project reports that “significant milestones in the construction of three deep level tunnels as part of the London Power Tunnels contract for National Grid” have been reached as part of a project to build new high voltage electricity cable tunnels between Hackney and Willesden (via St John’s Wood) and Kensal Green and Wimbledon. Read the full story here. Further information on the London Power tunnels project can be read here.

Delivering Power: The Future of Electricity Regulation in London’s Central Business District
23 March 2012: This report, commissioned by London First in conjunction with the City of London and City Property Association looks at the “long-standing concerns from developers about the challenge of securing a reliable and timely connection to the electricity network for new projects, particularly in the City and the West End where there is often little spare capacity.” Further detail here; report downloadable here.
Measure of the density of central London’s electricity demand.
The summary highlights problems associated with connecting new consumers to the distribution network, specifically:
- General communication and performance by the Distribution Network Operator (DNO) in dealing with developers could be improved. We recognise that in confidential interviews of this type there is a danger of focussing on the negatives, but found the level of dissatisfaction notable.
- There is a sense that developers cannot get the level of service they want,or indeed feel is necessary from the DNO. It is notable that developers stated that they would in general be willing to pay more for such a service,but this was not on offer from the DNO.
- In practical terms, developers expressed a preference for a quick guaranteed connection and suggested that a greater degree of anticipatory investment by the DNO would help to facilitate this.
- In relation to the third point, above, there is a lack of understanding as to why the DNO has not invested to a greater extent in London’s Central Business District (CBD) in light of the view that there will be a significant localized increase in electricity demand over the next ten years.
Mayorwatch has posted a news story which includes a comment from London’s DNO- UK Power Networks– in response to the study.
