Gridsight, an AI-powered capacity management platform for utilities, announced today that it has raised a $26 million Series B round led by Insight Partners.
Galvanize joined as a new investor, alongside existing backers Airtree, Energy Transition Ventures and Aera VC.
The funding will fuel Gridsight’s expansion across the United States while supporting continued growth in Australia, where the company was founded.
The raise comes as utilities confront what may be their most complex capacity challenge in decades, managing a surge of data centres, electric vehicles and distributed energy resources while trying to keep power affordable and reliable.
After roughly 15 years of flat growth, electricity demand in the US is climbing again, pushed higher by AI data centres, EV adoption and broader electrification.
Building new infrastructure cannot keep pace with that demand on its own, and as construction costs and timelines stretch longer, regulators are increasingly encouraging utilities to make better use of the grid they already have.
Gridsight estimates that as much as three-quarters of grid capacity sits unused on average, though that figure shifts depending on location, time of day and season.
The company’s platform is designed to give utilities a unified, real-time view of that available capacity, along with the tools to act on it.
Brendan Banfield, co-founder and CEO of Gridsight, said the nature of the problem is what makes it hard to solve.
“The grid’s capacity challenge is not uniform,” Banfield said.
He explained that while significant capacity exists for much of the year, it is unevenly distributed, constantly shifting and highly dependent on geography.
Gridsight’s platform, he said, helps utilities quantify that capacity, connect customers more quickly and steer investment toward the parts of the network where it will have the greatest impact.
Gridsight already works with major US utilities including Xcel Energy and United Illuminating, an Avangrid subsidiary.
Todd Conner, Senior Vice President of Electric Distribution at Xcel Energy, said the platform has become central to how his distribution teams plan and operate, turning raw network data into intelligence that engineers can put to use as the system grows more complex.
In Australia, Endeavour Energy has used Gridsight’s platform for real-time solar management, doubling static solar export capacity for households from 5 kW to 10 kW while pairing it with dynamic controls to protect the local grid.
The utility expects the program to generate more than $100 million in customer value and add 600 MW of solar capacity to the grid. Endeavour Energy CEO Danny Cooper credited the partnership, which began in 2021, with helping the utility adopt AI and make data-driven decisions about how it connects, manages and plans its network.
“We’ve doubled customers’ solar export capacity within our existing poles and wires, are operating the grid closer to its full potential, and delivering better value for our customers,” said Cooper.
At the centre of Gridsight’s technology is its Foundational Grid Model, a continuously updated, utility-specific model that consolidates fragmented grid data into a single trusted source.
The company pairs utility-specific grid models with electrical physics, rather than relying on general-purpose AI, so engineers can analyse complex networks and make faster decisions in real time.
Rachel Geller, Managing Director at Insight Partners, said the timing reflects broader pressure on utility networks as the energy transition accelerates.
“Gridsight’s platform provides the intelligence, visibility, and control needed to unlock latent capacity, connect more load, and stay ahead of demand without waiting for new infrastructure,” said Geller, adding that Insight Partners sees a substantial market opportunity in the US and is proud to back the company.
