Sustainability

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.

  • Industrial-scale heat pumps will efficiently utilize energy from adjacent water sources to produce eSteam™.
  • Electric boilers will use renewable electricity to power the industrial-scale electric boilers to produce eSteam™.
  • Thermal storage technologies will be used to produce eSteam™ from stored, off-peak renewable electricity.

How does eSteam™ work?

Vicinity will use a combination of heat pumps, electric boilers, and thermal storage technologies to create carbon-free eSteam™.

 

eSteam diagram

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.

Condensate heat recovery and reuse

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.

Benefits of condensate recovery and reuse

  • Lower energy and water costs
  • Reduced steam consumption
  • Improved system efficiency
  • Reduced carbon emissions and water use
  • Potential support for LEED, ESG, or other sustainability objectives

Vicinity can evaluate, design, and install condensate heat recovery or reuse solutions tailored to each building’s system, operating needs, and sustainability goals.

Common applications include: 

  • Domestic hot water preheating
  • Low temperature heating
  • Air handler preheating
  • Swimming pool preheating
  • Snowmelt and surface heating for sidewalks, walkways, or loading docks
  • Greywater systems
  • Irrigation, green roof watering, fountains, reflecting pools, or other water features
  • Power washing

Maryland Center for History and Culture (MCHC) reuses condensate in outdoor reflective pool to reduce water costs

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.

Steam trap inspection services

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.

Why preventative maintenance?

  • Improve reliability before peak heating season
  • Reduce outages, disruptions, and comfort complaints
  • Catch small issues before they become costly repairs
  • Support safer, more efficient equipment operation
  • Extend critical system life and performance

Available services

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.

Cities work because district energy works

Today, and every day, we’re paying tribute to those who put their hearts, minds, and backs into what they do for the good of our cities.

Together with our customers, partners, and community members, Vicinity Energy is building a stronger future for our cities, and district energy is part of that solution.

Accelerating downtown decarbonization with district energy

Vicinity Energy’s President and CEO Kevin Hagerty, along with Chief Sustainability Officer Matt O’Malley, participated in this informative webinar, “Accelerating Downtown Decarbonization with District Energy”, focused on the future of electrification strategies in downtown steam networks. The session, hosted by the International District Energy Association (IDEA), brought together leading voices in the district energy space to explore practical solutions for decarbonizing urban infrastructure.

Held virtually and featuring experts from across the country, the webinar highlighted how district energy systems are evolving to meet the growing demand for sustainable, resilient, and low-carbon heating solutions. As cities around the world set ambitious climate goals, the transition to electrified, carbon-free energy systems has become more urgent than ever.

The discussion centered on how major metropolitan areas like New York City, San Francisco, and Boston and Cambridge are leveraging district energy to support their climate mandates. These include New York’s Local Law 97, which sets strict emissions limits for large buildings; San Francisco’s Climate Action Plan, which aims to reach net-zero emissions by 2040; and Boston’s Building Emissions Reduction and Disclosure Ordinance (BERDO), designed to cut carbon emissions from existing buildings.

Hagerty and O’Malley shared insights into Vicinity’s own electrification journey, including innovative technologies like electric boilers and industrial-scale heat pumps that are key to decarbonizing its steam systems.

As the largest owner and operator of district energy systems in the United States, Vicinity Energy continues to provide innovative solutions that enable cities to reduce carbon emissions while maintaining reliable, safe energy service.
