Strategic investment will support Terragrit's continued growth and bring a faster, more accessible approach to testing operational decisions across the energy sector

NEW YORK, Sept. 17, 2026 /PRNewswire/ -- Terragrit, the leading AI platform for simulating changes to physical operations, today announced a strategic investment from National Grid Partners, the venture investment and innovation arm of National Grid (NYSE: NGG). The investment supports Terragrit's continued growth and deepens its work across energy and utilities, an industry where operational decisions carry higher stakes and less margin for error.

Utilities are managing infrastructure that is older, more interconnected, and under more pressure than at any point in recent decades. Demand is shifting faster than planning cycles can absorb, reliability expectations continue to rise, and the systems involved are complex enough that a change made to solve one problem can create another elsewhere in the network. Evaluating those tradeoffs has traditionally required specialized engineering tools, long development timelines, and technical expertise concentrated in a small number of teams, creating a bottleneck just as utilities need to move faster.

Terragrit addresses that challenge by giving teams a virtual sandbox where operational decisions can be built, tested, and compared before they're implemented in the field. Rather than functioning as a narrow simulation tool, the platform is designed as a collaborative decision-making environment: users construct a working representation of their operation, model a proposed change, and see how its effects move through the rest of the system, including capacity, resilience, cost, and sequencing implications. Because it doesn't require specialized engineering training, it puts that capability directly in the hands of the people who understand the operation, not just the specialists that legacy tools historically required. A utility facing a sudden demand spike, for example from a new data center, could use Terragrit to model options within minutes, such as upgrading a substation, adding a transmission line, or rerouting capacity. Each option's cost, timeline, and reliability tradeoffs can be compared before committing to one.

"Utilities are managing increasingly complex systems while facing growing pressure to make critical infrastructure decisions faster," said Arun Chetty, VP of Corporate Venture Capital at National Grid Partners. "Terragrit's AI-driven approach has the potential to unlock tremendous value for companies like ours. For the first time, cross-functional stakeholders can collaborate on a shared canvas to iterate physical environments faster. The same tool a maintenance worker uses to simulate options for immediately addressing downtime is also the tool used by infrastructure teams to plan grid evolution that supports the new era of datacenter demand. That's exactly the kind of practical value we look for."

"National Grid operates infrastructure that serves more than 80 million people across the U.K. and the U.S.," said Sam Nagar, founder and CEO of Terragrit. "At that scale, decisions can't afford to be wrong. That's exactly the scale this platform is built for, and it's the kind of relationship that will shape where we take it next."

Beyond capital, the relationship gives Terragrit access to National Grid Partners' industry expertise and connections, including the NextGrid Alliance, a network of senior innovation executives from more than 170 utility companies worldwide. That network offers feedback and domain expertise that shapes product decisions faster than building in isolation would. Terragrit will use the investment to accelerate product development and support continued commercial growth, with energy and utilities as an area of focus.

About Terragrit

Terragrit is an AI software platform that virtualizes operational decisions, giving organizations a way to build working models of their operations, test proposed changes, and understand their impact before implementation. With the flexibility of a spreadsheet and the fidelity of an advanced engineering tool, Terragrit gives more people the ability to participate in complex decision-making. Terragrit works across industries built around physical operations, from manufacturing and supply chain to energy, transportation, healthcare, and more, helping teams move from operational question to validated decision in minutes rather than months.
