Thermal storage provides hydraulic balance and thermal flexibility as the demand of heating and cooling varies dynamically. Intelligent cloud platform E.ON ectocloud™ connects and controls all parts of the energy system, providing state-of-the-art digital and data-driven services. Through advanced machine learning algorithms, optimal control strategies for the distribution and usage of energy, including the use of electricity, are continuously computed and applied, unlocking the full potential of E.ON ectogrid™. One low temperature thermal grid for distribution of heating and cooling consisting of one warm and one cold pipe, capable of sharing low temperature excess energy. Decentralized heat pumps that cool down buildings by turning down the temperature from the cold pipe of the grid and heat up buildings by turning up the temperature from the warm pipe.
