ON-SITE ENERGY MANAGEMENT SYSTEM FOR AN ENERGY-AUTONOMOUS CELL SITE

The present invention refers to an on-site energy management system, EMS, for an energy autonomous cell site in a cellular network wherein the cell site comprises at least one energy supply unit, at least one energy storage unit, and as at least one consumer at least one radio transceiver unit, wherein the EMS (300) comprises at least a decision logic module with data acquisition means and data processing means and configured to be implemented on a computing device that is a component of the cell site or at least operably coupled to the cell site, and, if implemented, be iteratively executed at a given time interval wherein each iteration initiates at the cell site in parallel controlling energy distribution (300A), energy storage (300B) and energy reduction (300C), by acquiring, using the data acquisition means, at least data about current energy generation and consumption at the cell site, current energy storage capacity at the cell site and current energy reduction commands for the cell site and providing, using the data processing means, respective energy distribution control data, energy storage control data and energy reduction control data. The EMS further comprises an interface module configured to be integrated in or at least operably coupled to the cell site and to detect the respective control data and to initiate, depending on the control data, altering an operating condition of/at the cell site and/or providing a status information about the cell site in response to the control data. The present invention also refers to an energy autonomous cell site and respective matter.
