Settlement price by fuel

The average amount generators were actually paid per kWh — it differs by fuel.

Not the same as the SMP for the month. The SMP is one price for the whole market; the settlement price is each fuel’s trading revenue (excluding RPS compliance and emissions-trading costs) divided by its traded volume (KPX definition).
