One Steam and hydraulic power plant to meet the energy needs of a region we have running in parallel. The annual load curve of the energy produced in the power plant is given in Figure-1 and the characteristics of the power plants are as follows: Steam Power Plant Hydraulic power plant

Plant installed power cost ($/kW): 1752 3723 Capital cost ( % ): 10 8 Fuel efficiency (%): 40 -- Fuel price ($/ton): 500 -- Fuel bottom thermal value(kcal/kg) : 6500 -- The hydraulic power plant is operated as a basic load " power plant. According to them; a) Unit energy cost for each power plant, b) Find the average energy cost by$/kWh unit.
