Company Overview
About Splight
Splight is a grid software company whose Machine Learning-based Dynamic Congestion Management system helps utilities squeeze significantly more clean energy through existing transmission infrastructure without building new power lines. The company raised $28.1 million in total funding and is executing its US commercial expansion in 2026, targeting utilities and grid operators facing severe interconnection backlogs from renewable energy projects.
Business Model & Competitive Advantage
The core insight is that transmission lines are rated conservatively based on worst-case thermal assumptions, but actual real-time temperature, wind speed, and load conditions usually allow much higher power flows. Splight's software continuously monitors these conditions and dynamically adjusts transmission ratings in real time — unlocking latent capacity on existing lines that static conservative ratings leave unused. Early deployments demonstrate up to 100% more capacity on existing infrastructure without laying new wire.
Competitive Landscape 2025–2026
The US grid interconnection queue has grown to over 2,800 gigawatts of proposed projects waiting for grid connection — more than double the entire installed capacity of the US power grid. Grid congestion and interconnection delays are now the primary bottleneck to renewable energy deployment. Splight's software addresses this bottleneck at a fraction of the cost of new transmission construction, and complements the DOE's $1.9 billion SPARK program for physical transmission upgrades.
