Gridsight Raises $26M to Find the Power Capacity Hiding in Plain Sight
Electric utilities do not only have a shortage of wires, transformers and substations. They also have a visibility problem.
That is the opportunity behind Gridsight, an Australian grid-software company that has raised a $26 million Series B led by Insight Partners. Galvanize joined existing investors Airtree, Energy Transition Ventures and Aera VC. The company plans to use the funding to expand in the United States while continuing to grow in Australia.
Gridsight’s argument is simple: electricity networks are often planned around static, conservative assumptions even though available capacity changes by feeder, location, time of day and season. Better data cannot remove every physical constraint, but it can identify where existing infrastructure is being underused and where new investment is genuinely necessary.
For geospatial professionals, this is what makes the company interesting. Gridsight is effectively building a living electrical model from smart-meter data, GIS asset records, SCADA telemetry and information about distributed energy resources such as rooftop solar and batteries. It calls the result a Foundational Grid Model. In practical terms, it is an electrical digital twin designed to answer a spatial and temporal question: how much can this part of the network safely carry right now?
From a map of assets to a model of capacity
Traditional utility GIS tells an operator where poles, conductors, transformers and customers are located and how they are connected. That spatial topology remains essential, but it does not by itself reveal the condition of the network at a particular hour.
Gridsight adds smart-meter observations and electrical modelling to estimate local loads, voltage conditions, distributed generation and constraints. The company says its platform can automate connection screening, run physics-informed annual power-flow studies and calculate dynamic limits for imports or exports.
That distinction matters. A static map describes the grid. A capacity model tries to predict what the grid can safely do.

This follows the broader move from static representations toward living digital twins, where operational value depends on keeping topology, measurements and real-world conditions aligned. The International Energy Agency similarly argues that AI can improve grid forecasting, situational awareness and optimisation, but only when utilities turn meter and sensor data into operational decisions rather than simply collecting more information.
The Australian deployment provides the strongest evidence
The clearest public case comes from Endeavour Energy, which operates an electricity-distribution network in New South Wales.
Its Flexible Exports service replaces a fixed rooftop-solar export ceiling with a limit that can change according to local network conditions. Eligible single-phase customers can export as much as 10 kW when capacity is available, compared with the previous fixed 5 kW limit. The utility can reduce exports when required to protect reliability.
This is not merely a vendor presentation. An Endeavour Energy report filed with the Australian Energy Regulator says the Gridsight platform had moved into business-as-usual use, with tools for load estimation, photovoltaic-system detection, hosting capacity, power-quality monitoring and dynamic operating envelopes fully operational. At the time covered by the report, the flexible-exports trial involved more than 200 customers.
Gridsight subsequently reported that a measured cohort of 359 customers exported 171 MWh over 12 months that would otherwise have been curtailed. Endeavour projects that scaling the programme could unlock approximately 600 MW of additional rooftop-solar capacity and return more than $100 million to customers by 2035.
Those larger figures are forecasts, not independently measured outcomes. The distinction is important. The operational evidence shows that dynamic limits can release additional solar exports. It does not yet prove that the full 600 MW and $100 million will be realised.
Australia’s regulator also treats flexible export limits as one tool among several for managing hosting capacity. Its guidance stresses governance, transparency and consumer protections, including a meaningful fixed-limit alternative. From November 2026, Endeavour plans to make flexible exports the default for eligible new and upgraded solar systems, while allowing customers to opt for a lower fixed limit.
The US expansion is promising but earlier-stage
Gridsight names Xcel Energy and United Illuminating, an Avangrid subsidiary, as US customers. Public evidence is more detailed for United Illuminating.
Connecticut’s Innovative Energy Solutions programme lists a $1.1368 million project that will apply Gridsight’s platform to United Illuminating’s existing smart-meter and GIS data. The goal is to identify non-wires alternatives to conventional capital upgrades and improve hosting-capacity analysis across the utility’s service territory.
That is meaningful validation of the problem and the procurement route, but it remains a demonstration. Gridsight has not published measured US results showing shorter connection queues, avoided capital expenditure or additional capacity released. Its claims that some analyses can run 10,000 times faster and unlock 21% more capacity than assumption-based studies also lack a public independent benchmark.
Competition will be substantial. Established utility-software groups such as Siemens, GE Vernova and Schneider Electric are extending their platforms, while specialists including Camus Energy, Utilidata and Neara address overlapping parts of grid modelling, flexibility and asset intelligence. Gridsight’s advantage will depend less on the phrase “AI-powered” than on model accuracy, integration with legacy utility systems and whether regulators trust its outputs.
Software can reveal capacity, not manufacture it
The Series B arrives as data centres, electric vehicles and distributed generation compete for grid access. That creates a compelling market for software that can turn fragmented operational and geospatial data into faster decisions.
But the strongest editorial lesson is also the limitation. A digital twin can locate capacity hidden by conservative assumptions. It cannot fix an overloaded transformer, build a missing transmission line or eliminate the need for engineering review. Faster analysis may also expose institutional bottlenecks elsewhere in the connection process.
Gridsight now has funding, an operational Australian reference and initial US utility projects. The next proof point is whether it can reproduce the Australian outcome across different network models, regulations and data quality conditions. If it can, utility GIS may evolve from a record of where infrastructure is located into a continuously updated decision layer for where electrification can happen next.
