Energy Management

The University of North Carolina at Greensboro’s energy usage for fiscal year 2017-2018 was approximately 55% natural gas, 42% electricity, and 3% No. 2 fuel oil. This energy usage is broken down into the following categories:


Natural Gas

Piedmont Natural Gas (PNG) provides service through individual meters to the campus and outlying properties. Natural gas is used as fuel for the boilers in the Steam Plant, domestic water heaters, cooking appliances, and generators. Excepting the Steam Plant and a few residential complexes, most accounts are small enough that the gas service is provided under PNG’s small general service rate or residential rate schedules. In fiscal year 2017-2018, the University’s total natural gas bill was $1,936,820 for 368,273 MMBTUs of gas. The Steam Plant used over 90% of the natural gas consumed.

Natural gas for the Steam Plant is purchased through State Term Contract 405N, which is currently held by Texican Natural Gas Company, LLC. Use of No. 2 fuel oil not only provides a reliable backup fuel but also allows UNCG to take advantage of the interruptible gas rate through the term contract. This capability enhances operational flexibility and results in significant cost savings.


Electricity

Duke Energy provides electric power to the campus through over a hundred accounts. Approximately 47 of those accounts are for the Lofts on Lee and Spartan Village-I and II on West Gate City Blvd. Others are for either leases for public lighting or for power to very small, dispersed loads such as irrigation systems, emergency phones, and entrance signs. In fiscal year 2016-2017, the total electric bill for the campus was $5,276,395 for 83,988,243 KW hours, or 286,568 MM BTUs of electricity.


Water

UNCG receives water and sewer service from the City of Greensboro. The University owns a distribution system that receives water through three (3) City master meters and distributes it to over 60 buildings. UNCG also has water service for several outlying properties as well. Most buildings on campus have UNCG-owned water meters that are read and manually entered into a database. Where water is used for irrigation or cooling towers, submeters have been installed so that the University can calculate non-sewer credits for water that does not enter the sanitary sewer system and receive appropriate reimbursement from the City of Greensboro. In fiscal year 2017-2018, the University water accounts totaled $1,099,897 for 132,712,640 gallons of water. The non-sewer water credits were for 50,037,280 gallons of water.
