Saving Energy in Industrial Compressed Air Systems: Issues and Obstacles in DSM Program Design
MetadataShow full item record
Compressed air systems are among the most common and least efficient electrical end uses in industrial plants. Over 50% of plants use compressed air systems. According to various estimates, between 20% and 35% of the energy used in these systems could be saved through improved system design and maintenance. After lighting, motors and HVAC, compressed air systems offer the greatest energy savings potential in industrial facilities. For this reason, there has been increasing interest in capturing this potential through utility-sponsored DSM programs. Baltimore Gas & Electric Company (BG&E) has been investigating compressed air program design since 1991, and has offered rebate programs since January 1992. This paper will review BG&E's experiences with its compressed air programs to date and will discuss future directions in compressed air program design. Topics to be discussed include: technology options, industry standards, availability of technical expertise, measurement of performance, and incentive mechanisms.
