Transmission and Distribution

Supporting the future energy network through the modernisation and upgrade of electricity and gas infrastructures

Systems supplied by Capula control the transmission and distribution of electricity to meet the energy needs of over 14 million people.

The energy system is changing rapidly, but the changes need to go further and faster.

The future energy network

As the UK focuses on a drive to net zero, transmission and distribution network operators are working in a changing energy landscape that, as well as regulatory pressures, now includes an increasing number of connected systems, different platforms and digital technologies, as well as changing priorities from its customer.

All of these factors demand new approaches to stabilise as well as optimise the grid, to:

Deliver safe, reliable and affordable grid operations
Optimise energy performance
Minimise risk and maximise performance and availability of key assets
Deliver innovation to support the energy system of the future

Technology agnostic
