A central received solar thermal power plant uses 1000 heliostats that have 60 m^2 of reflective surface each. The overall efficiency of the plant is 5 percent. The efficiency of the steam power plant is 30 percent. A constant 20 percent of the incident energy on the receiver is assumed to go to storage during operation.
1. Estimate the power plant output, in Megawatts, at peak conditions and at shutdown. Assume all efficiencies are constant during the day. You may assume solar incident flux is 1kW/m^2.
