A district needs 500 MW of power. The only option for this power production is the installation of the solar thermal power plant. Calculate the required mirror surface and the investments (in euros, ) for the heliostat field, receiver and steam generator systems, tower, other components, assembly and commissioning, design engineering consulting miscellaneous. Also calculate the total investment, operation and maintenance cost and power generation costs. Assume that the reference data table for the 30 MW is valid in the required problem.
