Energy conservation measures will save an estimated $3M annually

Working with SourceOne, recommended improvements and Energy Conservation Measures (ECMs), when implemented, are estimated to yield over $3M in annual energy bill savings.


The New York Power Authority (NYPA) sought to obtain Independent Contractor (IC) services to implement energy efficiency projects at the facilities of NYPA electricity customers in New York City and Westchester County. NYPA is the largest state-public power organization in the United States, operating 17 generating facilities and more than 1,400 circuit-miles of transmission lines.

This initiative supported NYPA's energy efficiency work to help achieve New York State’s ambitious "45 by 15" initiative to both reduce electricity use by 15 percent below 2015 forecasts, and increase the proportion of renewable generation to 30 percent of electricity demand by that year.

Under a multi-year contract, SourceOne has conducted energy audits for NYPA customers that ranged from large public institutions to small facilities, including Grand Central Terminal, The Metropolitan Museum of Art, NY Public Library, The Bronx Zoo and 17 others.

Through these audits, SourceOne has provided recommendations and has been responsible for the designing of energy-efficiency projects, putting them out to bid, and reviewing and selecting bidders. 
This has been done in collaboration with the Power Authority and the NYPA customers whose facilities are benefiting from the energy audits.Recommended improvements have included, steam system repairs, chiller replacements, air handler commissioning, lighting upgrades, energy management and metering improvements and other ECMs that, when implemented, are estimated to yield over $3M in annual energy bill savings.

transportation initiatives, NYPA's award-winning energy efficiency programshave contributed to helping make New York State a leader in energy savings. NYPA has undertaken energy efficiency and clean energy projects at more than 3,900  public facilities Statewide, saving New York taxpayers over $134 million a year and avoiding nearly 820,000 tons of greenhouse gases annually, which translates into the equivalent of avoiding the use of more than 2.5 million barrels of oil a year. 


The New York Power Authority does not use tax money or state credit. It finances its operations through the sale of bonds and revenues earned in large part through sales of electricity. NYPA is a leader in promoting energy efficiency, new energy technologies and electric transportation initiatives. It is the nation's largest state-owned electric utility, with 17 generating facilities in various parts of New York State and more than 1,400 circuit-miles of transmission lines. More than 75 percent of the electricity it produces is clean renewable hydropower. Its lower-cost power production and electricity purchases support hundreds of thousands of jobs throughout the state.
