Tri-Cities Landfill Scottsdale, AZ - 4000 kw
Landfill Energy Systems provided complete turnkey construction services including design, permitting, engineering, construction, equipment procurement and commissioning for the 4.0 MW facility located at the Tri-Cities Landfill. The landfill is located in Scottsdale, Arizona and is owned and operated by the Salt River Pima-Maricopa Indian Community.
The project was unique based on the entities involved, the Indian Community owns the landfill and the local utility owns the generating plant. This facility is the first landfill gas-to-energy facility to be constructed on Indian land.
The generating facility began commercial operation in May of 2001 and is owned by Salt River Project (SRP), the third largest municipal power supplier in the Country.
The plant is based on five CAT 3516 internal combustion engine generator sets rated at 800 kw each. These units are fueled by a centrifugal blower. Due to unique air quality restrictions, the traditional LES design was modified to include the addition of a thermal oxidizing flare.
SRP sells the electricity produced, which is sufficient to supply the power for approximately 4,400 homes and businesses, to their retail customers.
