Public Service Electric and Gas Co. and Robert Wood Johnson University Hospital Somerset announced on Wednesday the completion of $5.7 million in energy efficiency improvements that will save the Somerville hospital more than $600,000 annually in energy costs.
In a joint statement PSE&G and RWJUH said that the work was completed through the PSE&G Hospital Efficiency Program, a $199 million effort by New Jersey’s oldest and largest electric and gas utility that has helped dozens of Garden State hospitals to better manage their energy consumption
The energy efficiency improvements at RWJUH Somerset included a major upgrade to the hospital’s air conditioning chiller plant, the installation of energy efficient lighting fixtures and controls in the hospital and in the parking deck and the replacement of old, inefficient motors, fans and pumps with new energy efficient models.
The work at RWJUH Somerset will save more than 3.5 million kilowatt-hours of electricity and 226,000 therms (a unit of measurement for natural gas use over time) of natural gas annually.
That is enough electricity to power about 500 homes for a year and enough natural gas to supply about 225 homes for a year.
The PSE&G Hospital Efficiency Program targets hospitals and health care facilities located in PSE&G’s service territory. Through the program, PSE&G provides an audit and proposes various cost effective energy conservation measures that will make substantial improvements in the hospital’s efficient use of energy.
The program, according to PSE&G, greatly reduces the financial burden on a hospital by providing upfront funding for the total cost of a project. The hospital then pays back a portion of the total project cost over five years.
Work has been completed at 36 hospitals, with an average annual energy cost savings of more than $400,000 per hospital. The program has also saved enough kilowatt-hours of electricity to power more than 10,000 homes for a year and enough natural gas to supply more than 3,000 homes for a year. The initiative has garnered interest from almost every hospital in PSE&G’s service territory and currently has a waiting list of facilities that want to participate in the program.
