1. A power system for providing a fast acting spinning reserve, comprisinga turbine module operating in accordance with an organic Rankine cycle or steam power cycle coupled to a generator to satisfy a load,a main conduit through which motive fluid vapor heated in said organic Rankine cycle or steam power cycle is supplied to said turbine module,a flow control component operatively connected to said main conduit for automatically limiting the flow of the motive fluid vapor to said turbine module during base load conditions and for automatically increasing the flow of the motive fluid vapor to said turbine module during variable load conditions,a further turbine module operating in accordance with an organic Rankine cycle or steam power cycle coupled to the generator,a further main conduit through which motive fluid vapor heated in said organic Rankine cycle or said steam power cycle is supplied to said turbine module, and a further flow control component operatively connected to said main conduit, anda flow control component controller responsive to load conditions, for automatically limiting the flow of the motive fluid vapor to said further turbine module during base load conditions and for automatically increasing the flow of the motive fluid vapor to said further turbine module during variable load conditions,wherein said further main conduit through which motive fluid vapor heated in said organic Rankine cycle or said steam power cycle is supplied to said turbine module receives heat from the motive fluid of said turbine module operating in accordance with an organic Rankine cycle or steam power cycle coupled to the generator.
