Our solution, Energy Cloud, utilizes UPS batteries in cell-sites to deliver demand-response services to the power grid. The solution aggregates a high number of individual cell-sites, presenting and controlling them as one “combined site” to the power grid. An integrated part of the solution is testing and monitoring of UPS batteries ensuring a highly reliable UPS operation. The solution uses existing on-site rectifiers.
In addition, site indoor climate and equipment monitoring can be added minimizing the need for on-site maintenance visits and enabling remote optimization of both UPS and climate control. The solution can also be extended with ultra-low energy cooling that can be supplied from UPS and ensure cooling also in events of power outages.
Energy Cloud has been tested in a project together with the Danish TSO, Energinet, and one Danish network operator. The project showed that large groups of cell-sites can be operated as one combined site delivering demand response services to the power grid, and is ready for further scaling.
