It is often difficult to reinforce circuits in densely populated areas mainly because there is limited physical space available. London substations are commonly built underground, are therefore expensive to build, and can cause disruption during construction.

The project will evaluate if an urban distribution substation developed by a Spanish company (Twelcon) could help address these issues. The urban substation houses an Low Voltage (LV) panel, Ring Main Unit (RMU), Remote Terminal Unit (RTU) and Transformer (up to 1,000 kVA). Twelcon currently use continental equipment in the substation, hence development and further testing may be required to ensure that components meet UKPN specifications and perform efficiently and safely within the urban substation environment. The Twelcon substation also has 4 backlit advertising panels that could be used for public information.

The project has defiend the following objectives:

  • Reinforcement of stressed areas of the distribution network at 11KV

  • Relocation of substations which are currently difficult to access

  • Provide the means to serve urban Electric Vehicle (EV) charging infrastructure (including rapid charge units)

  • Potential solution for locations where aesthetics are important such as airports.
