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
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
- 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.
