The facility will make use of methane gas generated through organic decomposition in the state-owned landfill to potentially meet the power needs of over 4,800 homes.
Construction of the facility is scheduled to start in early 2016 and is expected to be operational in 2017.
Aria Energy president and CEO Richard DiGia said: "We are pleased to partner with Casella Waste Systems on the development, construction and operation of this baseload renewable energy project.
"The Juniper Ridge Landfill project adds to our portfolio of owned and operated landfill gas projects that play a critical role in powering more homes with electricity generated from renewable energy resources."
According to the US Environmental Protection Agency (EPA), the landfill gas-to-energy projects are expected to reduce reliance on non-renewable energy resources, such as natural gas, coal, or petroleum.
