Why is heat pump and thermal energy storage important?

Heat pumps and thermal energy storage for heating TES is very important in HP systems since it decreases the thermal capacity to less than the maximum heating requirement and enables a larger share of renewables. It balances system operation and allows an HP to operate at full capacity throughout the year, hence the SPF increases.
