Most Army central heating plants (CHPs) are about 30 years old. Many are nearing the end of their expected lives and experience poor combustion, low thermal efficiencies, and reliability problems. The most common solution for faulty CHP equipment is to replace it with the same technology. In some cases, however, the solution is to replace the large central system with many smaller, distributed gas-fired boiler systems. Although modernization of equipment can help avoid the high cost of the air pollution control equipment required for new energy supply facilities, the economic benefits gained from the early modernization programs have changed the life extension philosophy at most utilities. Utilities now view modernization as a long-term strategy or an ongoing policy for maintenance of and investment in existing power plants, not simply as a way to avoid the high cost of air pollution equipment. This report describes a screening tool and procedures to evaluate energy supply options to modernize or decentralize CHPs. The screening tool is to be used for a first level analysis of the suitability of central or decentralized plants using basic economic, climate, and real property data. If warranted, a more detailed conceptual analysis can be conducted which would then be the basis for initiating an energy supply implementation plan at the site. These guidelines do not represent a specific modernization program but rather a process to be adapted to specific needs at the Major Army Command and installation levels.In FY96 PAE charged Fort Carson $68, 000 for chiller operations, $64, 000 for chiller maintenance, $531, 000 for heat system maintenance, and $389, 000 for heat system operation.
