Avista Issues Request for Proposals for Renewable Natural Gas
Avista, through a request for proposal (RFP), is seeking to secure renewable natural gas (RNG) resources for its customers over the long term. RNG is derived from organic waste streams that would otherwise release methane to the environment as they decompose. These sources include, for example, landfills, wastewater treatment plants, food waste and dairy waste. RNG is produced by capturing that methane that would otherwise escape to the atmosphere and purifying it to make it very similar to conventional natural gas.
