The customer

Opened in 1962, the CFG Bank Arena is a multipurpose venue home to Baltimore’s premier sporting and entertainment events. The building stands at the original site of Old Congress Hall, where the Continental Congress met in 1776. Since then, it’s hosted monster truck rallies, NBA games, arena football games, and iconic musicians like The Beatles. The CFG Bank Arena can accommodate up to 14,000 guests and spans approximately 400,000 square feet in downtown Baltimore.

In 2023, the Oak View Group began managing the facility and renamed it CFG Bank Arena. During that transition, the Oak View Group and CAAIcon, a strategic management firm representing the arena owner, completed a $250 million renovation, which included the addition of modern acoustics, premium seating, and updated heating and cooling systems to the building. When it reopened in 2023, CFG Bank Arena was named the 10th highest-grossing venue in the world (10,000 -15,000 capacity) by Billboard magazine.

The challenge

Looking to expand the scope of services within the arena, the Oak View Group and CAAIcon partnered with Vicinity Energy to provide steam and chilled water to the building. To replace the facility’s onsite chillers and update its heating and cooling systems, CFG Arena needed to either install its own equipment or use a district energy system to source steam and chilled water. If the venue installed onsite boilers and chillers, they would occupy significant space and require large upfront investment. Not only does that mean less functional space for guest experiences, but it also requires a team to operate, maintain, and monitor this equipment.

The other challenge was compliance with Maryland’s Building Emissions Performance Standards (BEPS), which requires large buildings to reduce greenhouse gas emissions to net- by 2040. This local policy applies to any building over 35,000 square feet and mandates annual reporting and performance improvements. To meet these standards, the CFG Arena would need a heating and cooling solution that’s both affordable and sustainable.

The solution

Vicinity was an ideal match for CFG Bank Arena because not only does our Baltimore district energy system provide steam and chilled water solutions, but there was existing pipe infrastructure in place to connect to the building. This enabled an easier installation, leading to more usable space within the building, reduced costs related to installation and maintenance, and compliance with Maryland’s Building Emissions Performance Standards.

Maximizing building space through district energy solutions

By choosing district energy, CFG Bank Arena connected to Vicinity’s system without installing boilers or chillers in the building. That opened up more square footage and opportunities for new infrastructure such as additional club levels, premium seating, food and beverage stations, and other attractions that drew more guests to the arena. Rather than occupying valuable space with industrial equipment, CFG Bank Arena leveraged district energy to improve guest experience overall.

Reducing installation and ongoing maintenance costs

Vicinity’s solution saved the venue significant building space, but it also reduced installation and maintenance costs. By partnering with Vicinity, CFG Bank Arena did not have to install onsite equipment, saving upfront costs during the renovation. It also meant they didn’t have to monitor or maintain the equipment over time. Vicinity’s team would handle these operations for the arena, reducing staffing needs and payroll expenses.

Complying with local building emission standards

One of the most important solutions that Vicinity provides is clean energy that aligns with local policies like BEPS. In fact, Vicinity’s chilled water service allows buildings to comply immediately with BEPS. That’s because Vicinity’s district energy system is affordable and sustainable, helping large buildings like the CFG Bank Arena adhere to local policy without compromising heating and cooling needs. Buildings that are subject to emissions standards need to comply fully or risk being charged fees and other penalties by local government.

CFG Arena also has the option to transition to Vicinity’s eSteam™ services which is 100% carbon-free thermal energy. While the building is not required to connect to these services, the future flexibility makes Vicinity an affordable solution both now and in the future.

With the completion of these renovations in 2023, CFG Bank Arena continues to stand as a landmark venue in the city of Baltimore. By choosing district energy, it continues to create memorable guest experiences while meeting all of its unique heating and cooling needs.

Boston’s century-old steam heat system is getting a low-carbon makeover

Vicinity Energy Commences Construction of Industrial-Scale Heat Pump Complex in Partnership with DCO Energy and Everllence

Latest agreement affirms Vicinity’s commitment to decarbonization in Greater Boston, achieving net zero by 2050

Cambridge, MA, November 4, 2025 – Vicinity Energy, a decarbonization leader with the nation’s largest portfolio of district energy systems, today announced agreements with Everllence [formerly MAN Energy Solutions], and DCO Energy. This partnership secures the latest achievement in Vicinity’s electrification strategy that is already well underway in Boston and Cambridge, locking in the installation of a 35MW river-based industrial-scale heat pump complex for steam generation with the ability to reach over 70 million square feet of building space.

A significant portion of this industrial-scale heat pump has already been secured through long-term contracts with leading medical and educational institutions, even before construction has begun. This interest underscores both the strong demand and market confidence surrounding decarbonization.

The industrial-scale heat pump will be provided by Everllence while the installation and balance of plant modifications will be completed by DCO. A natural gas boiler will be removed to make way for the new, emissions-free heat pump, with demolition already underway in preparation for the heat pump installation at Vicinity’s Kendall Square facility by 2028. The heat pump will be collocated at the existing Kendall plant site, leveraging Kendall’s existing electrical interconnect. This technology will enable Vicinity to harness the inherent heat of the Charles River, turning it into a renewable energy resource to generate and deliver carbon-free thermal energy, known as eSteam™, to its customers.

As the baseload generating equipment for the company’s electrification plans in Boston and Cambridge, this innovative system will be the first to utilize the Charles River as a renewable resource to produce carbon-free steam, representing a significant leap forward in sustainable energy production. The company also plans to install thermal storage technologies to provide on-demand eSteam™ production from renewable electricity.

The net impact of the project is multifaceted: customers gain access to carbon-free thermal energy, citizens of Boston and Cambridge breathe significantly cleaner air, local laborers and unions gain access to quality jobs, and the Charles River ecosystem benefits from reduced temperatures.

“Execution of this project makes Vicinity’s vision of decarbonizing cities at scale a reality,” said Kevin Hagerty, CEO at Vicinity Energy. “Powered by renewable electricity to safely and efficiently harvest energy from the Charles River, this represents rapid advancement in electrification for U.S. district energy systems, demonstrating how proven heat pump technology can be deployed at scale to decarbonize cities. It enables immediate, scalable carbon reductions without the need for costly and time-intensive new electrical infrastructure in Greater Boston. We are establishing the blueprint of how to decarbonize a U.S. city and will be installing similar innovative electrification technologies at our district energy systems across 12 U.S. cities.”

The agreement with Everllence to build a river-source heat pump complex at Vicinity’s Kendall facility relies on the Charles River’s thermal energy, an untapped renewable energy resource.

“The heating sector still drives a major portion of global CO₂ emissions, and the energy transition simply cannot succeed without decarbonizing heat,” said Uwe Lauber at Everllence. “District heating remains one of the most efficient and sustainable ways to deliver thermal energy to commercial and industrial users. With this latest agreement, we are taking a major step forward with Vicinity to bring our proven mega heat pump technology to the U.S. market. Together, we are demonstrating how district energy systems can shift away from fossil fuels while maintaining resilience and performance.”

Previously, Vicinity installed a new 42MW electric boiler at its Kendall facility, which provides carbon-free thermal energy to its Boston partners through the established 29-miles of steam piping that runs underneath the city — the Boston and Cambridge district energy system. eSteamTM customers currently include IQHQ and Emerson College. By adopting eSteamTM , these institutions are not only advancing their sustainability goals but also positioning themselves to comply with local requirements such as BERDO and BEUDO, while aligning with Massachusetts’ Stretch Energy Code.

“Our priority is delivering reliable, practical solutions that make economic sense,” said Gary Fromer, CEO at DCO Energy. “Vicinity’s heat pump installation is a smart investment—it reduces emissions without compromising performance, and it’s built to operate efficiently over the long term. It’s a real-world step toward sustainability that works for today and the future. This collaboration builds upon the recent success of our joint projects in Philadelphia, further strengthening our track record of delivering innovative, sustainable energy solutions together.”

Building on the blueprint established in Boston and Cambridge, Vicinity is applying lessons learned to guide decarbonization plans in other cities. Progress is already underway in Grand Rapids, where installation of a 9MW electric boiler has begun, marking the city’s first step toward electrification. While each location will follow its own path and timelines, Vicinity is committed to advancing sustainable, scalable solutions across its portfolio.
