Emerald AI raised $150 million in an oversubscribed Series A on Aug. 25, valuing the company at approximately $1.05 billion and taking total funding above $220 million. The round was co-led by Energize Capital and DCVC, with participation from JERA Ventures, NVIDIA, Siemens and other financial and strategic investors. Emerald AI develops software that allows AI data centers to adjust electricity consumption in response to real-time grid conditions, helping relieve supply pressure. Its system can reduce power demand by up to 40% in less than a minute when the grid is under stress. The company plans to use the new capital to expand commercial deployments globally, with customers including leading AI companies, data-center operators and electric utilities. A December 2025 trial using 96 NVIDIA GPUs demonstrated the capability, and the company has since completed five commercial demonstrations. Emerald AI estimates the technology could unlock more than 100 gigawatts of existing U.S. grid capacity for AI data centers, roughly equivalent to the United Kingdom's total electricity generation capacity. Morgan Stanley expects global annual incremental electricity demand to exceed 1 trillion kilowatt-hours by 2030, with data centers accounting for nearly 20% of the increase. Emerald AI is also planning a 100-megawatt power-flexible AI facility in Virginia.
