Projects

2026 Feasibility Studies Lead participant

SwitchTwin

1 Feb 2026 to 31 May 2026

Awarded
£19,436
Total cost £21,596

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 ...

2026 Feasibility Studies

WPT for Grid

1 Feb 2026 to 30 Apr 2026

Awarded
£17,709
Total cost £19,677

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...

2025 Collaborative R&D Lead participant

DEsign for Live Line Technology Acceleration (DELLTA)

1 Nov 2025 to 30 Apr 2026

Awarded
£239,135
Total cost £265,706

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...

2025 Feasibility Studies Lead participant

Foundation Source Model (FoSMo)

1 Oct 2025 to 31 Dec 2025

Awarded
£19,062
Total cost £21,180

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,...

2025 Feasibility Studies

AI opportunities for consumer centric engagement

1 Sep 2025 to 31 Dec 2025

Awarded
£12,589
Total cost £13,988

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 ...

2025 Collaborative R&D

Future Operability of Gas for System Integration (FOGSI)

1 Jul 2025 to 31 Dec 2025

Awarded
£28,657
Total cost £31,841

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...

2025 Feasibility Studies

RAPID - Automated Routing Infrastructure

1 May 2025 to 31 Aug 2025

Awarded
£1
Total cost £10,125

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 ...

2025 Feasibility Studies Lead participant

DEsign for Live Line Technology Acceleration (DELLTA)

1 Feb 2025 to 30 Apr 2025

Awarded
£17,700
Total cost £19,669

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...

2024 Collaborative R&D Lead participant

Look NortH2

1 Nov 2024 to 30 Apr 2025

Awarded
£179,183
Total cost £199,092

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...

2024 Collaborative R&D Lead participant

Assessment of Superconducting Technologies for Standards Development

1 Nov 2024 to 30 Apr 2025

Awarded
£34,888
Total cost £38,764

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...
