Trane Technologies, an Ireland-based climate control systems company, is identified in city plans as the tenant for a manufacturing center in AllianceFlorida at Cecil Commerce Center.
It appears to be a plant for modular data center cooling systems.
City Certificate of Use and building-permit plans show that Trane will make tenant improvements in the 603,529-square-foot Building E at 5550 POW-MIA Memorial Parkway.
The Conlan Co. of Jacksonville is shown on plans as the contractor for the project, which is estimated at $1.78 million. Improvements include the addition of cranes, more lighting and equipment.
The work will include adding an exhaust fan for a new battery charging area, a new compressor room, a fenced storage area and sealing the slab construction and control joints.
Fernando Andrade of Dallas is the architect.
Trane Technologies, based in Swords, Ireland, announced Feb. 18 that it completed the purchase of Jacksonville-based Stellar Energy Americas Inc.
The acquisition was announced Dec. 2, 2025.
Trane, which calls itself a global climate innovator, said in the February news release that Stellar Energy is a leading provider of turnkey data center cooling solutions.
“The acquisition strengthens Trane Technologies’ leadership in data center thermal management solutions, while accelerating growth, innovation and scale for Stellar Energy,” the February news release said.
“Stellar Energy’s expertise in modular data center solutions combined with Trane Technologies’ operational excellence and global scale are well positioned to address the growing demand for pre-fabricated cooling systems and other critical equipment, which reduce supply chain constraints and enable rapid, scalable deployment.”
Holly Paeper, president of Trane Technologies Commercial HVAC Americas, said Stellar Energy’s strength in modular thermal system design “enhances our ability to lead as a trusted partner for this important sector as well as other complex commercial applications.”
“We look forward to building on their capabilities to deliver differentiated solutions that help customers achieve their growth, performance and sustainability goals,” Paeper said.
Trane Technologies said that through its Trane and Thermo King brands, it provides climate systems to buildings, homes and transportation.
Stellar Energy Americas now brands itself as Stellar Energy Americas, a Trane Technologies company. It is based at 1776 American Heritage Life Drive, Suite 700, in The Pondry office building near Butler Boulevard and San Pablo Road.
In announcing the acquisition agreement in December, Trane Technologies said Stellar Energy will retain its brand and operate under the commercial HVAC business of Trane’s Americas segment.
“The data center ecosystem is growing rapidly and evolving toward more agile, sustainable solutions, which is where Stellar Energy excels with leading co-engineered, modular solutions and a proven business model,” Karin De Bondt, chief strategy officer of Trane, said in a December news release.
Terms of the deal were not disclosed.
Trane was not immediately available to comment on the AllianceFlorida tenant improvements.
AllianceFlorida at Cecil Commerce Center
Dallas-based Hillwood is the city’s master developer of AllianceFlorida at Cecil Commerce Center.
Building E is on 45 acres at northwest POW-MIA Memorial Parkway and Finger Lake Street, north of the Florida State College at Jacksonville Cecil Center.
In a previous activity report to the city, Hillwood said that during August, several people from a prospect company toured the new 603,529-square-foot Building E, after which the developer provided selected plans and specs about the building.
Hillwood Executive Vice President Dan Tatsch said June 29 that Hillwood has several viable prospects for the building.
"I have no comment about the permit filing for Stellar Energy," Tatsch said by email July 16.
Stellar Energy already has a presence at AllianceFlorida at Cecil Commerce Center.
In June 2024, Stellar Energy cut the ribbon at a 510,433-square-foot facility at 12970 Normandy Blvd. It was the former Baker Hughes GE Oil & Gas factory.
Representatives from the power-system manufacturer said at the ribbon-cutting that the new West Jacksonville manufacturing facility will create 250 skilled-labor jobs by the end of 2024.
In October 2023, Jacksonville City Council unanimously approved a Recapture Enhanced Value Grant up to $1.5 million when the Stellar Energy expansion was code-named Project Orion.
According to Resolution 2023-0715, the then-unidentified company was described as an established manufacturer of mechanical equipment in Jacksonville and “operates a state-of-the-art manufacturing operation which designs, engineers and delivers modular equipment to aid power suppliers.”
A January 2024 announcement by JAXUSA Partnership said Stellar Energy plans to invest more than $28 million in the project, comprising $20 million in the building and more than $8 million in equipment.
Completion of improvements will be no later than Dec. 31, 2027.
JAXUSA Partnership is the economic development division of the JAX Chamber.
Stellar Energy also owns and operates a 115,000-square-foot facility at 989 Imeson Park Blvd. in North Jacksonville.
Stellar Energy analyzes, designs, constructs, fabricates, integrates, installs, operates, maintains and services energy systems.
It says its solutions include turbine inlet air chilling, inlet air conditioning, evaporative cooling, direct contact air chilling, thermal energy storage, district cooling and central utility plants.
