AssetCool Secures £10M To Scale Robotic Power Line Upgrades Worldwide

The company tackles a major energy challenge: grid congestion. As electricity demand rises, grid operators need faster, cheaper ways to expand capacity—especially with ageing infrastructure.

AssetCool’s solution is a special coating that can increase overhead power line capacity by up to 30%. It's also much more cost-effective—up to 20 times cheaper than traditional upgrades—and much faster to deploy.

Dr. Niall Coogan, CEO and co-founder of AssetCool, said: We are laser-focused on doing the hard yards to improve the physical layer of the grid, specifically overhead systems.

The AssetCool team is innovating at the nexus between robotics and materials science to bring meaningful improvements to an aging network. We’ve developed a new range of coatings systematically optimised for overhead lines that makes the grid more efficient and resilient - not by rebuilding it, but by enhancing what already exists.

AssetCool boosts the thermal performance of overhead power lines by applying advanced nanomaterials directly onto new or existing conductors.

Its “CapacityN” robotic platform enables fast coating application on live grid infrastructure. These smart robots also tackle issues like capacity limits, noise, and corrosion. Plus, they collect data, which is then analyzed using AI to offer real-time insights.

The £10M oversubscribed Series A round was led by Energy Impact Partners (EIP), with support from Extantia Capital, Taronga Group, and existing backers like Mercia Ventures, Kero Development Partners, and Northern Gritstone.

Sam Bursten, Principal at EIP, said: AssetCool stands out in the market with its ability to deliver firm capacity upgrades faster and more cost-effectively than any alternative we’ve seen.

We’re excited to partner with the AssetCool team and support their global growth, leveraging our strategic utility network to help them scale.

AssetCool combines advanced coatings with robotic systems to modernize power grids. From creating innovative materials to applying them on overhead lines and monitoring performance, the company handles it all.

Already working with utilities worldwide, AssetCool offers a faster, more cost-effective way to boost grid capacity and resilience—without the delays and high costs of traditional upgrades.
