A Hanover unit 02-048 fuel skid is used to remove the moisture from the Landfill gas, filters the gas for particles and increases pressure from 5" water column vacuum to 5 ps pressure. The Landfill gas is burned in 3 caterpillar 3516 Gengine/generator sets rated at 800 kw each, with outdoor radiators and sound suppression. Electricity is generated at 30 4160 volt and stepped up to 12.47 kv through a 3.5 MVA transformer. The high voltage switchgear is manufactured by Enercon utilizing vacuum reclosures and Schweitzer Electronic relay with full synchronizing capability. The 480 v MCC is manufactured by Culter - Hammer which provides 480 v power to station equipment. There are no electric distribution lines, substations, or transmission lines as part of this facility. The facility also contains a methane detection system and fire alarm system. Attached is a fact sheet explaining the above. 4b. Indicate the maximum Bross and net electric Hower production capacity of the facility Starting in October 2002, this facility was constructed with 3 - 800 kw units. In June 2006 the 4`" 800 kw unit will be brought on line. The engine/generators are rated at 800 kw @ .85 P.F. They typically operate at 820 kw @ .99 P.F. Facility capacity factor is in the 95% range. Current capacity: 3 x 820 kw - 100 kw (station power) = 2360 kw Current energy = 2360 kw 365 days x 24 hour x 95% = 19640 mwh Future capacity 4 x 820 - 134 kw (station power) = 3146kw Future energy = 3146 kw 365 days x 24 hour x 95% = 26181 mwh 4c. Indicate actual and expected operation dates 1 S` 3 800 kw units -October 2002 4`" 800 kw unit -June 2006 4d. Describe the primary energy input The energy input is landfill gas only at approximately 500 btu/cf to 550 btu/cf. Provide the average annual hourl energy input Engine generator heat rate is in the 11,600 btu/kwh range. Gas volume is in the 300 cfm range. Gas btu content is in the 525 btu/cf range. 300 cfm x 525 btu/cf x 60 min = 9,450,000 btu/hr per engine Or 28,350,000 btu/hr for 3 units. Energy input is landfill gas only.
