Avista Works to Extend Voluntary RNG Offering to Idaho, Oregon
Avista requested the approval of Idaho and Oregon regulators for a voluntary renewable natural gas tariff in those states, modeled after one implemented in November in Washington.
The Washington program was mandated by a 2019 law passed as House Bill 1257, which required that RNG be "available to all customers to replace any portion of the natural gas that would otherwise be provided by the gas company."
