National Grid Partners backs AI utilities platform Terragrit in early-stage round

What's the deal? TerragritDealroom has a profile for this one. Try Dealroom → has raised an early-stage strategic investment from National Grid Partners, the venture arm of National Grid (NYSE: NGG). The New York-based startup runs an AI platform that simulates changes to physical operations across energy and utilities. The deal was announced on September 17, 2026.

What does Terragrit do? Its platform gives teams a virtual sandbox to build, test, and compare operational decisions before deploying them in the field. Users model a proposed change — such as upgrading a substation, adding a transmission line, or rerouting capacity — and see how it moves through the rest of the system, including cost, reliability, and timeline tradeoffs.

Why now? Utilities are managing infrastructure that is older and more interconnected than ever, while demand shifts faster than planning cycles can absorb. Evaluating tradeoffs has traditionally required specialised engineering tools and expertise concentrated in a few teams, creating a bottleneck.

What's the money for? The capital will accelerate product development and commercial expansion across energy and utilities. Terragrit also gains access to National Grid Partners' expertise and the NextGrid Alliance, a network of senior innovation executives from more than 170 utility companies worldwide.

What they're saying: "Utilities are managing increasingly complex systems while facing growing pressure to make critical infrastructure decisions faster," said Arun Chetty, vice president of corporate venture capital at National Grid Partners. Founder and chief executive officer Sam Nagar noted that National Grid "operates infrastructure that serves more than 80 million people across the UK and the US," adding: "At that scale, decisions can't afford to be wrong."

The signal: The backing of a strategic investor tied to a major operator signals that grid modelling tools are moving from specialist engineering software toward accessible, cross-functional platforms — precisely as data-centre demand pressures aging networks.
