Source Ledger

Primary Sources We Use

KilowattLogic separates reported data, forecasts, and analysis. This ledger lists the public sources we use for energy market benchmarks, ISO/RTO market context, and regulatory claims.

How To Read Our Facts

Fact labels separate data from interpretation

API-verified

Values pulled from official APIs or structured public datasets, such as EIA, ISO/RTO, or regulatory data tables.

Source-reported

Values attributed to named filings, regulatory orders, public statements, market reports, or official notices.

Forecast

Forward-looking values from named forecasts, planning cases, consensus expectations, or clearly labeled scenarios.

KilowattLogic analysis

Procurement interpretation, scenario math, and buyer context derived from sourced facts.
