Eligibility / billing boundary: These periods apply to the Seattle city jurisdiction. Other City Light jurisdictions have different prices. The daily base service charge is not allocated to an appliance or EV session.

The state average is a benchmark, not a substitute for this tariff. A low or high encoded period is a marginal energy price and should not be interpreted as a complete monthly bill unless the page explicitly says whole-bill modeling is supported.
