    • The name "market_delivery_charges" says "charge": a word that usually means money moves, which cannot be taken back.
    Description, as the server wrote it
    Utility charges with effective dates. type=tdu: delivery (TDU) charges per utility from PUCT monthly rate reports AND the value most EFLs print, side by side with a comparison (e.g. Oncor's per-kWh charge differs between the two sources; both are shown). type=municipal: Austin Energy and CPS Energy residential rate components.
