Houston-based energy startup Joulent raised $1.75B in strategic financing from National Grid Ventures, securing the largest single funding round among US startups in a holiday-shortened week dominated by AI and energy deals.
Joulent builds energy infrastructure designed specifically for the demands of AI data centers and other compute-intensive industries. The company develops power generation and distribution assets that can deliver reliable electricity at utility scale, targeting the growing gap between grid capacity and the explosive power demands of AI model training and inference.
National Grid Ventures, the corporate venture arm of the UK utility giant, made the strategic investment as part of its push into the AI energy market. Data centers are projected to consume 9% of US electricity by 2030, up from roughly 4% today, creating an urgent need for new power infrastructure.
Joulent’s approach pairs traditional energy generation assets with advanced grid management software and battery storage systems, creating microgrids that can power large-scale AI compute clusters without stressing the broader grid. The company already has several projects under development in Texas and the southeastern US.
The $1.75B injection, structured as a strategic investment rather than a traditional VC round, reflects the capital-intensive nature of energy infrastructure. Joulent plans to use the funds to accelerate project development, secure site permits, and procure generation equipment for its pipeline of data center power projects.
The round highlights the growing convergence between the energy sector and AI infrastructure, as hyperscalers and AI companies scramble to secure power for their expanding compute footprints.
