Standby/Peak Generations
GUC offers the installation and operation of peak shaving generators as one of many strategies that GUC employs as part of its Load Management Program to offer an option for additional redundancy and cost savings.  Historically our Load Management Program has been successful due to the open communication we have with our industrial and commercial customers. Many have taken advantage of peak shaving opportunities by installing on-site generation.

Competitive Rates
Gas purchasing is an important aspect to reduce costs. Because gas prices go up and down so rapidly, and dramatically, GUC takes a systematic, disciplined and structured approach to our energy purchases. Our purchasing policy allows for longer-term planning. This purchasing strategy allows Greenville Utilities the best opportunity to offer our customers price stability and protection from the ups and downs of the market.

Liquefied Natural Gas (LNG) Facility
Greenville Utilities has applied the load management concept to natural gas, using liquefied natural gas during periods of high demand as a cost saving measure. GUC’s LNG facility allows us to ensure our system is always reliable. Recent Expansion has increased the facility to six storage tanks,  with which increases our LNG storage capacity by 50% for a total of 330,000 gallons. 

Compressed Natural Gas (CNG) Fueling Facility
GUC’s compressed natural gas fueling facility is located in close proximity to the Industrial and Business Parks.  Local industrial and commercial businesses not only have a less expensive fueling option for their large fleets, but can keep their fueling dollars locally.
