Battery Energy Storage and the Electric Grid
For a gas-fired combined cycle (CC) unit, the revenue from selling Responsive Reserve must be equivalent to what the unit could earn from selling the energy. For example, if the unit has an incremental cost of $21/MWH, and the wholesale power forecast for tomorrow is $26/MWH, the unit can earn $5 net revenue on the energy (the Spark Spread).
