PROVIDENCE WASTE TO ENERGY PLANT

The Providence project takes landfill gas extracted from a series of wells at the landfill and uses that gas in state-of-the-art combustion turbine generators to make electricity for sale to the local electric grid. The project is located at the Rhode Island Resource Recovery Complex in Johnston, RI, the second largest landfill to energy project in the country.

• The landfill gas-to-energy project utilizes landfill gas to reduce dependence on other natural resources and improves air quality and carbon emissions. 
• DCO was EPC for the project that utilizes a combined cycle plant to generate electricity.
• Major Equipment for the project includes: Solar Turbine Taurus 60 Units (4), Dresser-Rand Steam Turbine Generator,  Rentech Waste Heat Recovery Units (4), Cameron Natco Sulfur Removal, System, Venture Engineering Siloxane Removal System.
• Project takes landfill gas extracted from a series of wells at the landfill and use that gas in state-of-the-art combustion turbine-generators (CTGs) to make electricity for sale to the local electric grid. In addition, the exhaust from the CTGs will produce steam from waste heat recovery steam generators (HRSGs), which will power a state-of the art steam turbine-generator (STG) making additional electricity for the local electric grid.
• Facility includes gas blowers for the collection of the landfill gas, two stage gas booster / compression systems, gas treatment (H2S and Siloxane removal) systems, high voltage electrical distribution equipment, and related subsystems to produce the electric power and steam
• 28.2 MW Electricity, 93,628 lbs/hr Heat Recovery
