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.
