1. A thermal energy storage system, comprising:
a storage medium configured to store thermal energy generated by a conversion of input electrical energy from a renewable energy source having intermittent variability;
a heating element configured to thermally charge the storage medium by converting at least a portion of the input electrical energy to thermal energy and exposing radiation chambers of the storage medium to the thermal energy obtained from the heating element;
a heat extraction system configured to extract heat from the storage medium;
a steam generator configured to receive the heat extracted from the storage medium and to exchange the extracted heat with water from a water source to produce steam; and
a control system configured to:
measure a value indicating steam quality of the steam; and
based on the measured value, control a flow rate of the heat received by the steam generator.
