Guides

• How the average price is computed: revenue divided by sales, what goes into each side and what the result can and cannot tell you.
• Why a bill differs from the rate schedule: fixed charges, tiers, time-of-use periods, riders, taxes and how much power a household uses.
• What SAIDI and SAIFI mean: outage minutes, outage counts, major event days and why methods differ.
• Retail choice in EIA data: bundled, energy-only and delivery-only service, and why some respondents have no whole price.
