NAS Lemoore plans lease of 425 MW solar farm and construction of data center
The US Navy is working on a lease of 920 acres of land around the Naval Air Station Lemoore base to a Massachusetts company who would construct a large 425 MW solar farm and build a data center the size of three Costcos on the base campus.
This is the third run to lease surrounding land at the base by the government to produce energy that could help protect the facility power supply and offer resiliency. Similar projects were proposed in 2015 and 2023 but no construction ever happened.
Now there is a new investor who could build this project that now includes a 600,000 square foot power-hungry data center — one of hottest commodities on Wall Street these days.
A draft environmental document (Supplemental Assessment-SEA) published in June says a new lessee — Ameresco — could sell the generated power to regional customers, including the onsite data center. In return, the lessee would provide in-kind consideration in the form of energy generation to the Navy that would allow NAS Lemoore to work toward meeting both Navy and Department of Defense energy resiliency objectives. The project would include EV charging stations, a battery storage facility or BESS, backup generation/microgrid and related infrastructure.
A data center is a facility used to house computer systems and associated components, such as servers, storage systems, networking equipment, and other hardware. It serves as a centralized location for organizations to store, process, manage, and distribute large amounts of data. Data centers are
designed to provide a controlled environment with optimal conditions for the reliable operation of the computer systems. They have redundant power
supplies, cooling systems, and backup generators to ensure uninterrupted operation. They also employ various security measures, such as access controls, surveillance systems, and fire suppression systems, to protect the valuable data and equipment.
The data center would be connected to high-speed long haul fiber optic network for receiving and transmitting data. The facility would be primarily powered by on-site solar and battery storage for most of the year and would be connected to grid power for periods of low solar energy production.
vehicles, delivery trucks and service vehicles. During operations, the project site would have 20 employees, with staffing seven days per week, 24 hours per day.
A key factor that contributes to the rapid expansion of data center construction in the U.S. is digital transformation. As more businesses undergo digital transformations, the need for robust IT infrastructure to support cloud computing, big data analytics, and online services has skyrocketed, says one analysis.
Federal incentives have promoted investments. There are no data centers in Kings or Tulare counties.
Approximate Construction Timeline
Construction of the overall project would be expected to begin in 2024, says the document, with data center operations most likely commencing in 2025. The project can be constructed in single or multiple phases that are determined by the data center customer. Data center development typically can include up to five phases of approximately 20-25 MW increments that may extend construction time through 2027.
History of lease
The document is a Supplemental Assessment because the 2016 environmental study led to a lease of lands around the base that is still in place. NAS Lemoore encompasses 18,784 acres of Navy-owned land.
On Oct. 12, 2016, approximately 930 acres (i.e., Project Site) were leased to Liberty CO LLC for a term of 37 years (expiring Oct. 31, 2053). The existing lease with Liberty CO LLC was then transferred to Bright Canyon Energy on Feb. 14, 2019. In January 2024, Bright Canyon was acquired by Ameresco, and thus, as of 2024, Ameresco is now the current lessee of the undeveloped land.
Under the Navy’s 2024 Proposed Action, the existing lease would be modified to allow the lessee to construct and operate additional resilient energy systems within the leased 930-acre Project Site.
The existing lease allows the lessee to construct and operate up to a 125 MW solar PV system and associated infrastructure. The changes proposed as part of the 2024 Proposed Action would include the construction and operation of an additional 300 MW of solar PV systems (for a total of up to 425 MW) and an option to construct a data center, EV charging stations, BESS, backup generation/microgrid, and related infrastructure.
Ameresco, Inc. completed the acquisition of Clean Energy Asset from Bright Canyon Energy for $76.8 million, says their website.
Ameresco develops, owns and operates renewable-energy projects across the United States, Canada and Europe. In California, its projects include battery storage installations, including a $1.2 billion, 537.5-MW project that was delayed due to COVID-19 lockdowns and resulted in the company declaring a force majeure in April 2022. Ameresco was contracted to construct the battery storage systems for SCE at the utility’s substations in Ventura and the Los Angeles area.
The environmental document says once construction starts, it will employ about 400 construction workers.
A final SEA is expected before work begins.
