JERA Backs Startup Developing Solutions for Grid-to-Data Center Projects

JERA Co Inc said it has invested in United States-based startup Emerald AI Inc through its venture capital arm to support the development of software that aims to improve the flexibility of electricity consumption at data centers.

"Emerald AI's software platform enables the coordination of AI computing workloads and onsite energy resources with real-time grid conditions", a joint statement said. "By dynamically adjusting flexible computing workloads and energy use in response to grid signals, data center operators can manage electricity demand more flexibly while maintaining the performance of priority AI applications.

"Through this investment, JERA will explore opportunities to combine Emerald AI's software capabilities with the JERA Group's expertise in power generation, renewable energy, battery energy storage and power supply-demand operations.

"The two companies will also consider opportunities to develop solutions that support the growing demand for both electricity and computing capacity, as well as potential new business opportunities in Japan and overseas".

JERA Ventures head Takeshi Kodama said, "The rapid growth of AI is creating significant new demand for electricity and increasing the need for closer coordination between computing and power systems. Emerald AI is developing an innovative approach to this challenge, and we see strong potential in combining its software capabilities with JERA's expertise across the energy value chain".

Earlier Japanese power utility JERA announced a partnership with Newlab New Orleans to develop and commercialize next-generation carbon capture technologies for gas generation facilities.

"Under the partnership, JERA and Newlab New Orleans will evaluate and select a group of promising PSC [point-source capture] startups and, within 2026, identify one technology for deeper development and potential commercialization", JERA said December 3, 2025.

Earlier in 2026 JERA completed the acquisition of U.S. upstream natural gas assets in which it sees potential for supply to data center power projects.

The acquisition of the South Mansfield gas assets on Louisiana's side of the Haynesville shale gas basin from GeoSouthern Energy Corp and Williams Upstream Holdings LLC included an upfront investment of $1.5 billion by JERA.

"The Haynesville acquisition's strategic value is supported by robust current production and proven reserves, established gathering, treating and transport infrastructure, and proximity to Gulf Coast LNG and data center hubs", JERA said in an online statement October 23, 2025.

JERA said at the time South Mansfield, spanning about 210 square kilometers (81.08 square miles), was producing over 500 million cubic feet a day and had 200 undeveloped locations. "The transaction includes a future investment plan under which JERA will increase total production to 1 Bscfd [billion standard cubic feet per day]", JERA said.

"Louisiana is a strategic priority for JERA, and the Haynesville acquisition - in addition to our other commitments across the state - underscores our intention to be a long-term partner in Louisiana's energy economy", said JERA Americas chief executive John O'Brien.
