Gridsight has raised a US$26 million Series B funding round led by Insight Partners, with participation from Galvanize and existing investors Airtree, Energy Transition Ventures and Aera VC.
The Sydney-founded company said it will use the funding to accelerate its expansion in the United States, while continuing to grow its operations in Australia. Gridsight positions its software as a capacity management platform for utilities, aimed at helping network operators make better use of existing grid capacity as electricity demand rises.
The company cited renewed growth in US electricity demand after a prolonged period of stagnation, attributing the increase to AI data centres, electric vehicles and broader electrification. It argued that building new infrastructure alone will not meet demand quickly enough, pointing to higher costs and longer construction timelines, and said regulators are shifting incentives toward improving utilisation of existing networks.
“The grid’s capacity challenge is not uniform,” said Brendan Banfield, Co-founder and CEO of Gridsight. “For the majority of the year, significant capacity exists; but it is uneven, dynamic and geographically dependent. Our platform helps utilities quantify that capacity, connect customers faster and direct investment to the pockets of the grid that maximize its impact. Our goal at Gridsight is to use data and intelligence to ensure energy is an enabler for economic and technological progress, not its limiting factor.”
Gridsight said it is working with US utilities including Xcel Energy and United Illuminating, an Avangrid subsidiary. In Australia, it said Endeavour Energy deployed its platform for real-time solar management, doubling static solar export capacity for households from 5 kW to 10 kW, paired with what it described as real-time dynamic control to protect the local grid.
“Australia leads the world in rooftop solar adoption, and Endeavour Energy is at the forefront of that transition. Gridsight has been an invaluable strategic partner since 2021, helping us embrace AI and make data-led decisions on how we connect, manage, flex and plan our 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. We’re proud of our partnership with Gridsight and the work we’re doing to accelerate Australia’s energy transition.” said Danny Cooper, CEO Endeavour Energy.
Gridsight said its platform is built around what it calls a “Foundational Grid Model”, which it described as a continuously updated model that consolidates fragmented grid data into a single view of the network. It said its AI agents combine utility-specific grid models with electrical physics to support real-time engineering analysis and decision-making.
“Gridsight is now an integral part of how our Distribution teams operate and plan, turning data our network produces into intelligence our engineers can act on. As complexity in our distribution system continues to grow, this partnership helps us make rapid decisions to safely get the most out of our existing grid.” – Todd Conner, Senior Vice President, Electric Distribution Xcel Energy
Insight Partners said the investment reflects growing pressure on utility networks as electrification and data centre load increase.
“The energy transition is stress-testing utility networks in ways they were never designed to handle,” said Rachel Geller, Managing Director at Insight Partners, “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. The US market opportunity is substantial, and we’re proud to back this team.”
