A power plant having multiple steam boilers for supplying steam for processing and for powering a turbine generator comprises a steam turbine having first and second stages, a steam powered processing unit, a plurality of steam boilers, each having a primary steam generator and a reheater, a system of steam lines for conducting primary steam from the steam boilers to said turbine, and to the process unit, return lines for returning cold steam from the first stage of the turbine to the reheaters for reheating, and lines for conducting reheated steam from the reheaters to the second stage of the turbine; and isolating valves in the lines with pressure relief valves on each side of the isolating valves for selectively isolating each of the boilers from the turbine and conducting primary steam through the reheaters of the boiler and to the processing unit.
