The EPA has recognized five facilities with the Energy Star Combined Heat and Power Award for their CHP systems’ operating efficiencies ranging from 69 to 75 percent, much higher than the efficiency of separate production of electricity and thermal energy, which can be less than 50 percent.
The winners are:
The medical centers’ and universities’ increase in operating efficiency reduces their energy costs and prevents carbon pollution.
New York Presbyterian Hospital/Weill Cornell Medical Center and New York University have each reported annual savings of approximately $5 million while Texas A&M University reported savings of nearly $150 million in the last 10 years, according to the EPA.
By using CHP, the winners are able to operate independently from the grid during power supply disruptions, such as those from weather-related events. CHP’s benefits for universities include uninterrupted electricity, heat, and cooling for dormitories and classrooms, and protection of data centers and research activities that are vulnerable to losses of air conditioning and electricity.
With CHP systems, hospitals ensure that patient care can continue uninterrupted, and that vital assets such as medical research facilities, diagnostic laboratories, and pharmaceutical supplies are safeguarded.
Established in 2001, the EPA’s voluntary CHP Partnership program seeks to reduce the environmental impact of power generation by promoting CHP. The partnership works closely with energy users, the CHP industry, state and local governments, and other clean energy stakeholders to facilitate the development of new CHP projects and to promote their environmental and economic benefits.
Global commercial CHP capacity will more than double by 2022, growing from nearly 39 GW in 2012 to 79.5 GW, which represents $11.2 billion in annual revenue, according to a Pike Research report.
