Description:	Cost of unit starts and shutdowns

Generator Start & Shutdown Cost is the cost incurred for starting and shutting down units

For chronological simulation phases (see LT Plan Chronology, MT Schedule Chronology and ST Schedule) this is:

Start & Shutdown Cost = Start Cost × Units Started + Shutdown Cost × Units Shutdown

When using multiple cooling states (hot, warm, cold for example), the reported start cost is based on the active cooling state. The active state can be inferred from the Hours Down output property.

The Start Cost referred to here includes:

The Start Cost; and
The cost of Start Fuels as defined by the Offtake at Start.

The cost of emissions due to fuel used at start-up is not included here. Those costs are rolled in to the reported Emissions Cost.

For LT Plan and MT Schedule with Chronology = "Partial" the property is defined as:

Start & Shutdown Cost = Start Cost Mark-up × Generation

where the "Start Cost Mark-up" is defined by the setting LT Plan Start Cost Amortization Period, or MT Schedule Start Cost Amortization Period.
