It will be true the vast majority of the time that TPmin < SRMC+ < TPmax . The above formulas have been simplified below given this condition is true.
Price_type
The allocation rules are designed to ensure that the unit will not be generating if a FRRP less than the TPmin is expected to occur. Similarly the allocation rules are designed to ensure that the unit will be generating at full capacity if the unit is operating between TPmin and TPmax but the FRRP is likely to increase above TPmax . For every dispatch interval, one of four price_types are One of four price_types is assigned to every dispatch interval, where a price_type is defined as follows:
if TPmax < FRRP then price_type = 10
...
if FRRP <= TPmin then price-type = -10
Price_phase
One of four price_phases is assigned to every dispatch interval, where a price_phase is defined as follows:
if PT = 10 then PP = 10
else PP = min(PTi =1 to n) where PTi <> 10 for all i (where i is a dispatch interval)
end
Relative prices
The bid allocation rules defines price_type and price_phase that are a function of TPmin, SRMC and TPmax.

PT = -10 | PT = -1 | PT = 1 | |
---|---|---|---|
PP = 1 | N/A | N/A | > TPmin |
PP = -1 | N/A | <SRMC+ | >TPmin |
PP = -10 | <TPmax | >SRMC+ | < SRMC+ |
