Power Potential

The Transmission and Distribution Interface 2.0 (TDI 2.0) project, now known as Power Potential, is a world-first trial to maximise network capacity to connect more renewable energy and storage technology in the South-East region. By working jointly together, UK Power Networks and National Grid aim to open up new markets for distributed energy resources and generate additional capacity by alleviating transmission and distribution constraints. The outcome will be more renewable energy connected to the network and savings for our customers.

Project data

Start date: 02/01/2017
End date: 31/12/2019
Budget: £9,560,113.13 jointly with National Grid

Power Potential aims to create a new reactive power market for distributed energy resources (DERs) and generate additional capacity on the network. This project is a world-first and could save energy consumers over £400m by 2050. It could also generate up to an additional 4 GW in the South East region of the UK.

The three-year study is based in the South East region of the UK, where the connection of distributed energy resources is growing rapidly. Given the region’s location, there is also high interconnection with continental Europe with HVDC links of 2GW, increasing to 5GW with future projects.

Power Potential is a world-first project, which will see more coordination between the national System Operator, National Grid, and DNOs like UK Power Networks. As renewable generation, such as wind and solar, becomes a growing source of power on the UK’s power distribution networks, Power Potential will increase system flexibility by using more DER resources and provide network support at a distribution and transmission level for the first time.

The project will create the opportunity for our engineers to assess a range new technologies to explore new energy markets. One of the key facets of Power Potential’s strategy through a system called Distributed Energy Resources Management System (DERMS), a computer software-based piece of equipment designed to integrate more distributed solar and other energy renewable resources.

Power potential will test brand new technology designed to facilitate our FutureSmart strategy and create a smart grid for all – one capable of reducing the UK’s carbon emissions 80% by 2050.
