On this page, you can find out how we’re developing new ways of facilitating low-carbon outcomes.
As a responsible business, we continue to investigate different ways to manage and reduce the impact of our network, business activities and operations on the environment.
Below, you’ll find a number of new ways we’ve developed to facilitate low-carbon outcomes.
Innovation: sulphur hexafluoride (SF6)
Sulphur hexafluoride is an extremely effective electrical insulator and has significant advantages over alternative materials. However, SF6 is also a potent greenhouse gas, with a global warming potential (GWP) of 22,800 times stronger than CO2.
We’re exploring new initiatives and SF6 alternatives including: gas insulated lines, alternative gases and capture techniques. These are part of our continued efforts to take care of the environment for current and future generations.
Network capacity map
The increase in smaller renewable generation is placing greater and more complex challenges on the electricity transmission system than ever before. There are some regions of the network that can no longer accommodate these connections without expensive and timely reinforcement works on the transmission network.
To mitigate potentially long lead times for expanding transmission capacity, we’ve developed an interactive digital Network Capacity Map to help developers assess available capacity in England and Wales. This enables low-carbon generation to get connected quicker so that society can enjoy the benefits of cleaner energy.
Managing our land
It's important that we manage the land we own in ways that create the most value for us and our stakeholders, and for the wider environment in which we operate.
Through our Natural Grid programme in the UK, we're working with local communities and stakeholders to make the best of our green spaces and efficiently manage them in a way that benefits local communities and habitats.
We're also minimising the impact of our construction projects, as we work to maintain and expand our energy networks.
Electrification of transport
The momentum behind the shift towards electric vehicles (EVs) is now clearer than ever. The UK Government’s announcement to stop all sales of petrol and diesel cars by 2040 is the latest in a string of high-profile policy decisions in recent months.
We’re working with the Government, the energy sector, and industry to integrate millions of electric vehicles successfully. We’re exploring how to support a network of transmission-connected ultra-rapid chargers at key strategic locations e.g. motorway services.
