Ben, please find attached revision one to the UAE - Lowell, Massachusetts
LM6000 simple cycle peaking facility, which is to be located at an existing, staffed cogen facility. The revisions are due to the following changes in assumptions: 1. Increased annual maintenance costs due to going from 4 to 5 LM6000PC Enhanced Sprints units being installed. This increases the CO + SCR units, compression capacity and the chiller capacity. Some consumables increase as well (test gases for CEMS, oils, greases, etc) 2. Chemical costs increased due to NOx emissions limit from 5 ppm to 2.5 ppm. Amount of aqueous ammonia changed from 46 lbs/hr to 76 lbs/hr (per Peerless, Inc. quote - they package the CO + SCR system using 19% solution, which keeps operator below EPA RMP threshold of 20%) 3. Reduced the staffing costs due to no allocation of labor being assumed from existing plant to peaking plant (per your discussion with UAE). Two O&M tech staff adds are shown to cover the peaking operation only. 4. Chemical costs increased due to more throughput required. Assuming a RO + mixed beds installation per Bruce Golden. 5. Increase in O&M Fee from $80M/yr to $100M/yr due to scope increase. 6. Major Maintenance dollar value increased in absolute terms due to adding one more GTG (fyi, $/fired hr stays the same). Please call if you have questions or want to discuss further. regards, Scot
