The 1,000 kWh Bill-Credit Threshold: What One Kilowatt-Hour Costs

Key findings

1. Across 11 EFL-verified bill-credit plans, using 999 kWh instead of 1,000 kWh raised the recalculated monthly bill by $124.79 to $124.82 (median bill $62.03 at 1,000 kWh vs $186.84 at 999 kWh).
2. The same plans averaged a median 6.2¢/kWh at 1,000 kWh, 19.2¢ at 500 kWh and 12.3¢ at 2,000 kWh, as published on their EFLs.
3. All 11 plans come from 1 provider; the result describes this plan design, not the whole market. EFLs were issued 2026-10-15 to 2026-10-28 and are historical.

Methodology

• Power Hopper analysis of plan data compiled from Power to Choose-derived third-party listings and REP Electricity Facts Labels. The listing files are secondary sources (third-party mirrors of Power to Choose); they are not official Power to Choose data and are not republished. Only aggregated statistics derived from Electricity Facts Label (EFL) components are published.
• Each EFL record gives the provider's average price at 500, 1,000 and 2,000 kWh plus its components: the utility's per-kWh and monthly delivery charges, any recurring provider base charge, and any bill credit with its usage threshold.
• Reconciliation: Power Hopper solves for the energy charge (and, where no base charge is stated, one constant monthly amount) that reproduces all three published averages, then checks every level to within the label's 0.1-cent rounding (±0.05¢). Records that do not reproduce are flagged, not used.
• Only records the source file marks as EFL-verified are eligible. Records marked unverified, failed, carried forward or not re-checked are excluded from findings. Each distinct EFL is counted once per utility (latest issue date).
• Monthly bills at 999 and 1,000 kWh are recalculated from the reconciled components: energy charge plus delivery charges times usage, plus monthly charges, minus the bill credit where usage meets the threshold.

Limitations

• Historical: EFLs change. These figures describe the labels as issued on the dates shown, not current offers.
• Small sample: 11 plan-utility combinations from one provider. Other bill-credit plans in the listings were excluded because their EFLs were not verified in the source files.
• The 999 kWh bill is a recalculation from EFL components, not a provider-published figure. Taxes and other pass-through fees are not included.
• 5 distinct EFL records reproduce only if a credit described as applying above 1,000 kWh is applied at exactly 1,000 kWh; they are excluded and listed for review.
