Given the unit data in Table , calculate the production cost for a 250-MW demand.

Unit	Capacity(MW)	Forced Outage Rate	$/MWh
A	100	0.1	15
B	150	0.2	25
C	200	0.25	40
TIE	1000	0	80

(1) Give the deterministic solution (no outages).

(2) Give the deterministic solution with unit derating.

(3) Give the probabilistic solution using state enumeration.

(4) Give the probabilistic solution using the convolution method
