•A high temperature PTES (HT-PTES) is proposed based on an electric heater.•The energy storage density of HT-PTES is more than twice that of PTES.•When combined with ORC the performance of HT-PTES improved significantly.•A novel parallel ORC is proposed to recover the heat at high temperature.•HT-PT...
