EXPERIENCE SUMMARY

Mr. Koch is in his twenty-fifth year specializing in the thermal performance analysis of generating units and is in his twelfth year as an independent consultant.

He has been with the Heat Balance Group of Stone & Webster Engineering Corporation, and with the Boston Edison Company. He has extensive experience in all aspects of power performance testing and analysis.

In recent experience involving performance analysis and testing of combined cycle units, he has:

• conducted tests for three large combined cycle plants, pinpointing causes for lost performance
• done feasibility studies for GT inlet air cooling and fuel gas heating, including cost estimates
• developed a detailed performance model for HRSG temperature control systems
• performed a cogeneration assessment of a diesel engine heat recovery unit
• directed contract performance testing for O&M contractor performance clause compliance
• run performance acceptance tests for retrofit HRSG sections at several combined cycle units
• provided training in heat balance calculation techniques to utility performance engineers
• optimized performance for an eight-cell cooling tower, resulting in increased unit output

Mr. Koch has calculated heat balances for over a hundred units, including design of basic cycle configuration, sizing and selection of major equipment, and development performance data for pro forma analyses. He is an experienced and licensed user of FCYCLE/CCYCLE heat balance software, which he uses regularly as a part of his work.

Previously, with Stone & Webster, Mr. Koch directly supervised or participated in testing of numerous units, ranging from a 30-MW wood chip fired unit to the world's largest combined cycle cogeneration plant. The scope of these tests were both performance improvement and contract acceptance, on behalf of both owners and lenders. This included witnessing tests, as well as review of procedures and test reports.

At Boston Edison's fossil stations, totaling 1700-MW in oil- and gas-fired capacity, Mr. Koch was responsible for monitoring and improving all aspects of unit performance. He developed a unique format for quantifying heat rate losses, tabulating the effects of individual parameters, and revised methods for calculating and verifying incremental dispatch data. He also initiated an innovative approach for analyzing unit start-ups, which resulted in changes which will extend unit life.
