About Avista Rates and Tariffs
Understanding your bill
We all use energy to power our homes and businesses. But for Avista, the cost of that energy is regulated. What you see on your bill is what state utility commissions deem fair and reasonable. Your rate dollars support affordable, safe, reliable energy—learn how rates are set, what your rate dollars fund, and how we maintain our systems.
