1 Feb 2026 to 31 May 2026
As Great Britain aims for Net Zero, Inverter-Based Resources (IBRs) are vital for network operations, but their power electronics (PEs) present challenges for grid resilience and capacity utilisation due to unpredictable degradation. This causes operators to under-utilise thermal capacity, leading to inefficiencies and premature replacements. Traditional ...
1 Feb 2026 to 30 Apr 2026
This project investigates the use of wireless power transmission (WPT) to enable quicker, more-flexible grid connections and overcome delays associated with installing traditional cabled infrastructure. This offers a rapidly deployable alternative for connecting new generation, demand, and interconnection assets, with applications ranging from generic gri...

Alpha phase will expand on learnings from Discovery which reviewed the need of outages to maintain the reliable and resilient networks. Outages cause operational issues and constraints costs which can be lessened by usage of Live Line Working (LLW) enabling better asset health/management. Reliability and economic impacts of LLW including different down-s...
1 Oct 2025 to 31 Dec 2025
The UK electricity network stands to gain significant advantages from deep learning-based computer vision models for asset management; reduced analysis and data collection costs, improved output quality, lower lifecycle costs from consistent assessments and better predictive models. Independent development of these models by individual networks is costly,...

Our project tackles a key barrier to expanding the UK's net zero gas and power networks: how to engage the public inclusively, effectively, at scale, reducing opposition and construction delays. Traditional methods are too slow and resource-intensive. In this phase, we will identify consumer needs and explore novel AI-driven engagement solutions, such as ...
1 Jul 2025 to 31 Dec 2025
The project will develop an integrated hierarchical network modelling framework for simulating the operation of future GB energy system scenarios with highly interconnected gas and power networks. The realistic modelling of power-to-gas and storage operators' behaviour will be emphasised. The integrated models will be demonstrated on a simulation platform...
1 May 2025 to 31 Aug 2025
The Winser report makes recommendations concerning faster delivery of new transmission infrastructure including standardisation and automation of route design for new transmission lines. This Project, in direct alignment with the Winser report, will examine the problems that need to be solved to address the recommendations concerning the process of route ...

Electrical grid owners regularly perform complex repairs and maintenance tasks to make sure the network is reliable. However, many of the complex operations require outages, and this can put a pressure on the rest of the electrical network and its future development. Live Line working can relieve this pressure, however electrical infrastructure is current...

The scale of investment required to capitalise on GB's abundant offshore-wind resource and decarbonise our economy by 2050 and power system by 2035 is vast. Developing the infrastructure to allow energy from these resources to reach consumers, whether electricity or hydrogen, is expensive, technically complex, creates system operability challenges and can...
1 Nov 2024 to 30 Apr 2025
Superconducting systems have five to ten times higher power density than the equivalent voltage conductor, meaning they deliver higher capacity at lower voltage levels and via a lower number of routes. This will allow faster network capacity increase, delivering time, cost, and carbon savings. Superconducting systems can also deliver a reduction in energy...
