System and method for controlling energy generation, storage and/or consumption units coupled together

The method involves coupling an energy production unit with a consumption unit such that energy required by the consumption unit is estimated by a rule and/or prognosis algorithm based on consumption profile in the past over a time response. The energy required by the consumption unit is adjusted by the energy production unit. Multi-capacity of a storage unit, which is not adjustable by the energy production unit, is supplied. Buffer capacity is adjusted by the storage unit. The energy production unit is formed by a combined heat and power unit. An independent claim is also included for a system for coordinated control of energy production-, storage- and/or consumption units.
