Hitachi, Ltd. a U.S. firm specializing in investment management of Special Purpose Vehicles and project management, today announced a strategic collaboration agreement to develop dedicated energy parks designed as behind-the-meter power supply hubs with co-located, gigawatt(GW)-scale infrastructure for AI data center off-takers in North America. A project-specific limited liability company that will own and operate the energy park to provide EaaS to its off-taker clients.
An energy park is an on-site power supply hub that integrates power generation and storage facilities, transmission & distribution (T&D) infrastructure, and energy management systems. Designed and built to serve as a primary power source while coordinating with the regional power grid, energy parks enable reliable and controllable large-scale power procurement without waiting for grid reinforcement, thereby contributing to the accelerated development of large industrial facilities.
Through this partnership, the parties aim to provide the full lifecycle of energy parks — including design, development, operation, and power supply — as Energy as a Service (EaaS) via a SPV. This approach is intended to create an environment in which data center operators can secure stable power necessary for business expansion without undertaking large upfront capital investments or managing complex energy operations on their own. Looking ahead, SPVs operated by X LABS will lead project financing, site selection and development, and project management, with plans to complete the first energy park in the early 2030s.
By combining Hitachi’s GW-scale T&D technologies and grid stabilization capabilities with X LABS’s technology-driven investment and operational expertise, the parties will address power procurement bottlenecks faced by data center operators and contribute to sustainable data center operations as well as to solving societal challenges through the deployment of AI.
Background
The rapid expansion of AI and cloud services is driving a surge in data center development. In the United States, however, aging power infrastructure is struggling to keep pace with demand, making reliable power procurement a critical bottleneck for data center expansion.
In response, hyperscalers developing large AI data centers are increasingly turning to energy parks that secure on-site primary power by combining multiple generation sources, energy storage, and energy management systems. Unlike conventional kilowatt (kW) or megawatt (MW) scale microgrids, designing and operating GW-scale energy infrastructure that requires strict power quality demands substantial capital investment and specialized expertise, creating a significant burden for operators.
To address this challenge, the energy parks developed through this collaboration adopt an EaaS model that integrates facility development, operation, and power supply, enabling customers to access stable power quickly without owning assets or managing complex energy operations.
Role and responsibilities in the collaboration
Hitachi brings deep customer-focused insight into power procurement and operations, with Hitachi Energy providing power system capabilities across high-voltage T&D, grid stabilization, and power quality. Through the One Hitachi approach led by its Strategic SIB Business Unit, Hitachi will support stable and efficient energy park operations by providing T&D solutions, advanced grid-interconnection technologies, and energy management systems incorporating battery energy storage systems (BESS). Hitachi also aims to further advance and optimize energy operations by leveraging HMAX Energy*2, one of the HMAX by Hitachi suite of next-generation solutions that brings the power of AI to social infrastructure.

X LABS is an investment and development company founded by a former CEO of a global asset management firm and a former CTO of a global technology group. Leveraging deep insights into advanced energy technologies and business developments, X LABS will lead the overall project management of energy parks, including the establishment and management of SPVs, investment, site selection, procurement, and project financing. Through these SPVs, X LABS will develop and operate the energy parks and supply electricity to customers under an Energy‑as‑a‑Service model.
