Boston-based steam company Vicinity sold in $3 billion deal
At Vicinity Energy, we are leveraging our existing district energy systems and deploying innovative technologies to reach net zero carbon emissions by 2050 or sooner.
To reach net zero carbon emissions, we are electrifying our operations using three proven technologies.
Vicinity will use a combination of heat pumps, electric boilers, and thermal storage technologies to create carbon-free eSteam™.

Procure
Vicinity will procure electricity from renewable, carbon-free energy sources and import the power through a co-located electric substation.
Produce
Powered by renewable electricity, electric boilers and industrial-scale heat pumps will transform water into eSteam™.
Optimize
Thermal storage provides on-demand eSteam™ production from stored, off-peak renewable electricity.
Distribute
Carbon-free eSteam™ will be distributed to customers through underground piping infrastructure.
Biogenic fuels
Vicinity utilizes waste cooking oil discarded by the local food service industry to generate steam to heat and cool businesses and institutions in the very same community. A truly circular solution, Vicinity is consuming this fuel in many of our central plants to reduce our reliance on fossil fuels.

Improve steam system efficiency, reduce operating costs, and support sustainability goals with condensate heat recovery and clean water reuse services from Vicinity.
Many steam systems discharge hot condensate that still contains valuable heat and clean, treated water. Vicinity helps customers capture and reuse this resource to lower energy and water costs, improve system performance, and reduce environmental impact.
Vicinity can evaluate, design, and install condensate heat recovery or reuse solutions tailored to each building’s system, operating needs, and sustainability goals.
The Maryland Center for History and Culture developed a creative solution to pipe condensate into an adjacent outdoor reflecting pool, helping reduce sewer charges and city water costs. By recycling condensate instead of discarding it, MCHC conserves water, lowers costs, and reduces its environmental impact on the surrounding community.

Maximize steam efficiency, safety, and cost savings and keep your steam system operating at peak performance with proactive steam trap inspections from Vicinity ProService.
Our trained technicians use advanced ultrasonic digital detection technology to identify failed, leaking, or blocked steam traps before they lead to energy waste, equipment damage, or safety concerns.
Lower energy costs
Identify and eliminate steam losses that increase energy consumption and operating expenses.
Improve equipment reliability
Extend the life of steam system components and reduce unplanned downtime. Deliver high quality, dry steam throughout the system.
Enhance workplace safety
Reduce the potential for condensate buildup and dangerous water hammer incidents.
Support sustainability goals
Improve energy efficiency and lower associated greenhouse gas emissions.
Identify immediate savings opportunities
DOE analysis shows that repairing a single failed steam trap can save thousands of dollars annually, depending on operating conditions.
According to the U.S. Department of Energy, 15% to 30% of steam traps in systems that have not been maintained for 3 to 5 years may have failed, resulting in significant energy losses. Regular inspection programs can reduce failed trap populations to less than 5%.
Schedule a site walkthrough to get a scope and proposal for steam trap testing. Upon approval, qualified Vicinity technicians will perform inspections using thermal and ultrasonic equipment. First-time surveys include trap tagging and cataloging for future tracking.
Receive a comprehensive report that includes:
Vicinity’s comprehensive maintenance services are offered year-round—during peak usage or before system turn-ons—to optimize steam efficiency, reliability, and cost savings.
Steam trap surveys
Ensure steam traps function correctly and prevent issues that can lead to energy waste, equipment damage, and safety hazards.
Pressure Regulating Valves (PRVs)
Maintain PRVs for efficient system operation and prevention of system over-pressurization.
Strainers
Reduce rust and pipe scale damage to valves and pumps. Ensure heat transfer surfaces are kept free of efficiency-reducing deposits.
Heat exchanger and water samples
Ensure heat exchangers are operating efficiently, tube bundles are not leaking, and that water is not entering the system through leaks.
Steam pipe
Inspect steam pipe and insulation integrity to ensure safe and reliable delivery of steam to the facility.
Condensate return line
Ensure proper evacuation of condensate from system lines, and identify the presence of leaking steam traps in the system.
Mechanical room hot water loop
Confirm efficient operation of key energy transfer equipment such as heat exchangers, which supply building heat, hot water, or other process loads.
Seasonal and maintenance shutdowns/turn-ons
Prevent pipe deterioration and prepare systems to be dormant for an extended period by draining the systems for shutdowns.

Oklahoma City, OK
581,000
Home to the NBA’s Oklahoma City Thunder, the Paycom Center has been a cornerstone of Oklahoma City since 2002. It’s owned and operated by the City of Oklahoma City and has hosted more than 1,200 events since its opening.
With a capacity of over 18,000 seats and over 500,000 square feet of building space, the arena is designed to NBA and National Hockey League standards. The multi-purpose venue also hosts an array of entertainment events including professional sports, concerts, and live TV such as WWE.
The City of Oklahoma City passed a bond issue in 2023 to build a new arena to replace the Paycom Center. The site selected for the new arena was a city-owned facility that provided onsite heating and cooling to the Paycom Center. To start the demolition of the new arena site, the city needed to provide an alternate source for heating and cooling to the original Paycom Center. They also needed to avoid disruptions to the arena event schedule, which included the NBA season.
The Paycom Center needed to solve its heating and cooling needs very quickly. So, Vicinity Energy worked alongside several industry partners to produce a completely unique solution.
Vicinity teamed up with engineering firm FSB, equipment supplier EEI, and local contractor United Mechanical. The team leveraged EEI’s long-term relationship with Grundfos, an international manufacturer, to produce a heating and cooling system that was reliable but could be installed rather quickly.
In this system, hot water and chilled water equipment was designed for Grundfos to mount on skids. The skids were manufactured offsite at a Grundfos facility to ensure no onsite disruption at the Paycom Center. When complete, the skids were transported to the Paycom Center, wheeled in, piped up, and turned on. Without disrupting major operations within the building, the Paycom Arena could now leverage Vicinity’s heating and cooling services for its facilities.
The following video provides more information about the installation process:
The Paycom Center plays an integral role in Oklahoma City. It’s home to a premier NBA franchise and is a popular venue for hosting live events. Vicinity Energy was chosen because of its flexibility and customizable solutions, allowing the City of Oklahoma City to make necessary improvements without jeopardizing critical operations.
The partnership between Vicinity Energy, FSB, United Mechanical, EEI, and Grundfos enabled the Paycom Center to quickly implement a reliable, flexible heating and cooling solution. By leveraging district energy and innovative equipment, the venue achieved significant cost savings while providing a comfortable guest experience for attendees.
When our customers at the Paycom Center in downtown Oklahoma City needed to transition hot and chilled water service to the new arena in time for the OKC Thunder season, Vicinity and our partners came together to manage this complex project.
This new case study from Grundfos highlights how the Oklahoma City Paycom Center is improving performance through a collaborative approach with Engineered Equipment Inc., FSB Architects + Engineers and Vicinity Energy.
