LineVision Raises $37.5M Series C+ Led by New System Ventures

LineVision, a Boston-based provider of transmission grid intelligence for electric utilities, has raised $37.5 million in Series C+ funding. The round was led by New System Ventures, with participation from National Grid Partners and Centaurus Capital.

What LineVision Does

LineVision combines physics-based modeling with ground-truth data from field-deployed sensors to deliver Dynamic Line Ratings and situational awareness through its NexusIQ platform. The company works with large utilities and transmission owners in the United States and the United Kingdom, including National Grid, AES, Southern Company, TVA, NV Energy and Exelon.

The Problem LineVision Addresses

LineVision's utility customers are working to optimize and expand grid capacity as demand from AI data centers, advanced manufacturing and electrification outpaces new transmission build. Rather than relying solely on new construction, LineVision's approach is aimed at helping transmission owners get more out of the infrastructure they already operate.

The Round at a Glance

Company: LineVision
Headquarters: Boston
Round type: Series C+
Amount raised: $37.5 million
Currency: USD
Funding date: September 17, 2026
Lead investor: New System Ventures
Additional investors: National Grid Partners, Centaurus Capital

Why This Round Matters

The Series C+ structure signals continued momentum at a stage where the company has already established a commercial footprint with major utilities on both sides of the Atlantic. The presence of National Grid Partners among the investors is notable given that National Grid is also named among LineVision's utility customers.

For utilities and transmission owners evaluating grid intelligence vendors, LineVision's positioning rests on the combination of physics-based modeling and field-deployed sensor data — a pairing the company says underpins both its Dynamic Line Ratings and its broader situational awareness offering.

What to Watch

With demand-side pressure from AI data centers, advanced manufacturing and electrification continuing to strain existing transmission capacity, the market for grid optimization technology remains a focal point for utility investment. LineVision's ability to convert its existing utility relationships into expanded deployments — and to add new transmission owners in the US and UK — will be the key measure to track following this raise.

Summary

LineVision has closed a $37.5 million Series C+ round led by New System Ventures, with National Grid Partners and Centaurus Capital participating. The Boston company provides transmission grid intelligence, including Dynamic Line Ratings and situational awareness via its NexusIQ platform, to utilities and transmission owners in the US and UK.
