The Merchant Plant model is similar to the PPA Single Owner model, except that power generated by the system is sold at market prices that can vary on an hourly (or subhourly), daily, or monthly basis over the project life. Revenue can be from energy production, ancillary services and capacity payments, or a combination of the three.
Forecast pricing data to use with SAM's Merchant Plant model is available from NREL's Cambium databases.
