Connecting Decentralised Energy to London’s Electricity Network

September 2011: Back in May Ofgem issued an ‘open letter’ requesting views from the distributed generation (also commonly called decentralised generation) industry of their experience of connecting projects to the local electricity network. Ofgem’s letter sets out that they:

“consider  that the efficient development  of distributed generation  could play an important role in addressing a number of key policy issues.   These include helping the UK to achieve its targets for reduced carbon emissions as well as improving the  security of energy  supply and  addressing  fuel poverty issues. To this end,  we have endeavoured to ensure that  those seeking to connect  distributed  generation to the network  do not encounter any unnecessary barriers resulting from the way that the electricity distribution networks are operated and regulated.”

The increased use of decentralised energy is a key element of London’s energy strategy, and the Mayor has established a target for 25% of London’s heat and power to be sourced by localised DE schemes by 2025.

Ofgem have now published a useful ‘High Level Summary’ of responses which highlights the difficulities that DE operators experience when bringing forward a project. This includes the:

  • Limited and inconsistent distribution network data available to generators
  • Costly processes ranging from connection assessments to legal fees
  • Prohibitively complex grid code requirements placed on these smaller distributed generation systems.

No regional aspects are highlighted in the findings – that is – is it any harder/easier to connect DE to London’s electricity distribution system (operated by UK Power Networks in the main and also SSE in SW London) than anywhere else, however, if London is to significantly increase its use of DE, the numerous barriers identified by smaller generators that currently exist need to be removed.

Low Carbon London

July 2011: Executive Summary of UK Power Networks (London’s electricity distribution network operator) Low Carbon London bid to the second round of Ofgem’s £500m Low Carbon Networks Fund. Doesn’t reveal a lot – the bid is very ‘techy’ as can be seen from the early submission to Ofgem in November 2010, but parts of the proposal are covered in story below.

London companies to be paid to curtail peak-time energy use

8 July 2011: Industry article highlighting UK Power Networks (London’s electricity distribution operator) plans for demand reduction where Large companies in London will be paid to curb their energy use during peak demand periods as grid operators plan ways to avoid costly upgrades to the UK capital’s congested electricity networks. This proposal forms part of UK Power Network’s  bid into Ofgem’s Low Carbon Network Fund (see ‘Low Carbon London’ story for further information). Business Green also provide further detail on this story.

Low Carbon London

28 November 2010: Full submission proforma to Ofgem by EDF Energy for their bid into the Low Carbon Networks Fund for its  Low Carbon London project. The project is looking to develop “a new approach to distribution network management to meet growing demand from emerging low carbon technologies such as electric vehicles, heat pumps and distributed generation. It will focus on carbon reduction targets and the need to reduce dependency on conventional reinforcement.” Updates to the project are posted by Ofgem here.
