Gas : 0.6 $/MBtu . The coal costs 14 $/ton and has an average heat content 125-- Btu/lb (1 ton = 2000 lb) Unit 2 is on a take-or-pay supply contract and must burn 500 tons of coal during the 8-h time period. Assume both units are on-line and they should meet the following load : Period Duration Load (MW) 1 4 hours 400 2 4 hours 650 For a starting value of y = 12 $/ton, in iteration 1, the power output of Unit 2 during time period 1 is equal to : a. 100 MW b. 200 MW c.
