Led by Insight Partners with participation from Galvanize, the round will accelerate US expansion of Gridsight’s AI-driven capacity management solutions amid the strongest sustained growth in electricity demand in decades.

SAN FRANCISCO, Sept. 1, 2026 /PRNewswire/ — Gridsight, the AI-powered capacity management platform for utilities, today announced it has raised a US$26 million Series B led by Insight Partners, with participation from Galvanize and existing investors Airtree, Energy Transition Ventures and Aera VC. The round will accelerate Gridsight’s US expansion while supporting continued growth in Australia at a moment when utilities face their most complex capacity challenge in decades, connecting a surge of data centers, EVs and distributed energy resources while keeping power affordable and reliable for the customers and communities they serve.

US electricity demand is rising after fifteen years of stagnant growth, driven by AI data centers, EVs, and electrification. But new construction alone cannot meet this growing demand. As the cost and timeline of building new infrastructure climb, regulators are shifting incentives toward better use of existing grid capacity. The opportunity lies within existing networks, where as much as three-quarters of grid capacity goes unused on average, varying by location, time of day, and season. Greater visibility and smarter management of this latent capacity allows utilities to connect more load today, without waiting for new infrastructure. Gridsight’s intelligent platform gives utilities a unified view of available network capacity and the tools to act on it in real-time.

“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 is already working with leading US utilities, including Xcel Energy and United Illuminating, an Avangrid subsidiary. In Australia, where Gridsight was founded, Endeavour Energy deployed Gridsight’s unified capacity management platform for real-time solar management, doubling static solar export capacity for households from 5 kW to 10 kW paired with real-time dynamic control to protect the local grid. This program is expected to unlock more than $100 million in value for customers and 600 MW of additional solar capacity for the 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.

At the core of Gridsight’s platform is its Foundational Grid Model, a continuously updated, utility-specific model that brings fragmented grid data into a single, trusted view of the network. Unlike general-purpose AI, Gridsight’s AI agents combine utility-specific grid models with electrical physics to help engineers analyze complex networks in real-time, make better, faster decisions, and drive automation.

“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

With deployments at leading utilities across the US and Australia, Gridsight is translating platform capability into measurable outcomes at scale. This round of US expansion comes as demand growth accelerates and grid investment cycles lengthen, meaning utilities are increasingly looking for solutions that deliver results within existing infrastructure. This is the problem Gridsight was built to solve.

“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.”
