Splight raises $12.4mn to expand transmission capacity amid surging data center demand

SAN FRANCISCO, CALIFORNIA (By Splight, 26.Aug.2025, Words: 460) — Splight, a US-based grid technology company deploying machine-learning solutions that unlock capacity on congested electric grids, today announced a $12.4mn SAFE funding round led by Blue Bear Capital, with participation from ZOMA Capital.

The funding will support Splight’s continued expansion in North America and Europe, with a focus on scaling both its commercial and technical teams at a time of unprecedented growth in demand for power from electric grids across the globe.

“Our technology solves one of the most urgent problems facing the grid today: how to deliver more electricity without waiting years for new transmission to be built,” said Fernando Llaver, CEO and co-founder of Splight. “This new capital allows us to scale deployments of our flagship Dynamic Congestion Management™ product, unlocking the kind of transmission capacity that is urgently needed by grid participants like AI data centers and utility-scale grid resources.”

The new funding will enable Splight to:

  • Accelerate the deployment of its Dynamic Congestion Management™ (DCM) in the U.S., where grid congestion and decades-long transmission construction timelines are resulting in the curtailment of renewable energy resources and multi-year grid interconnection queues for new generation and large loads alike.
  • Launch new technical capabilities, including:
    • AI-Enabled Electrical Studies for Data Centers: Splight’s brand-new approach to electrical studies brings the antiquated process into the 21st century and considers new capabilities based on real-time data to shorten data center interconnection timelines.
    • Enhanced DCM™ algorithms: New capabilities to help grid participants navigate the evolving requirements for integrating new large loads.
    • DCM™ Sandbox: A new modeling tool that streamlines the ability of operators to visualize potential DCM-enabled transmission gains in a virtual grid environment, which will include a demo control center in Splight’s expanded SF office.
    • Real-Time Simulation (RTS): A new feature for solution validation which allows engineers to conduct Hardware-in-the-Loop testing directly in the Splight Technology platform.
  • Expand the footprint of its headquarters in San Francisco, relocating to a new office space along the Embarcadero and growing the headcount of its Bay Area-based technology and product teams.

Using its advanced machine-learning algorithm to safely and reliably unlock capacity on existing transmission lines, Splight’s DCM™ solution has seen rapid adoption across various geographies and regulatory environments. Unlike Dynamic Line Rating (DLR) solutions – which depend on weather and other variable conditions, resulting in a limited increase to capacity – DCM™ introduces an entirely new layer of grid reliability by ingesting real-time grid data and using a proprietary machine-learning algorithm to turn every Fast-Responding Asset (FRA) on the grid into a source of added robustness for the system. Using Splight’s DCM™ technology, FRAs, such as battery storage and data centers, become operational tools that can reliably respond to varying grid conditions to consistently unlock up to 100% more transmission capacity on existing infrastructure (dependent on system characteristics).
