Abstract

The present invention provides a method for producing load-following power using low to medium temperature heat source fluid comprising the steps of reducing the power level produced by a Rankine cycle power plant producing load-following power operating on a low to medium temperature heat source fluid during one period of time.' storing heat not used during the first period of time; and using the heat stored for producing power during a second period of time.
