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™.

Steam trap inspection services

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.

Benefits of a Vicinity ProService steam trap survey

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.

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.
