As an energy systems study for the University of North Carolina at Chapel Hill demonstrates, steam-driven absorption chillers, when combined with cogeneration, can be more cost-effective than electric-driven chillers. In the course of modeling high-steam and low-steam cases for chilled water production, the author found that UNC had the ability to meet much of its chilled water needs with steam and that increasing electric production by increasing steam sales reduced costs, mainly because producing chilled water with steam lowered electric demand and because the overall price the local utility paid for cogenerated electricity exceeded the overall cost of the increased electric production. Others should not be slow to take advantage of similar opportunities.
