GridPayouts.com is an independent residential electricity tariff research database built to bridge the gap between 80-page Public Utility Commission (PUC) rate filings and accurate homeowner math.
How We Verify Utility Payouts & Rate Schedules
- Capacity Adjustments & Riders Included: Every rate on a calculator page has a source link and a “Last verified: Nov 12, 2026” stamp. Numbers we could not confirm on a primary official page are labeled estimates or omitted. Duke’s monthly Battery Control credit uses a 0.709 capability factor cited from installer FAQs that quote Duke; the factor can change. Georgia Power energy and fuel charges come from the TOU-OA, TOU-RD, and TOU-FCR PDFs; ECCR, DSM, and franchise riders remain labeled estimates.
- Incremental Storage Cost Isolation: When utilities bundle solar and battery rebates (such as PowerPair's $3,600 PV + $5,400 storage structure), we never subtract solar panel rebates from battery-only price tags.
- Post-2025 Federal Tax Accuracy: Following the December 31, 2025 expiration of the residential Section 25D 30% clean energy credit under P.L. 119-21, all homeowner-owned models default to 0% federal tax subsidy while separating third-party Section 48E commercial lease pass-throughs.
