Demonstration

The NETfficient Use Cases

Based on a „Smart Island“ concept, NETfficient will demonstrate and deploy local storage technologies in a real grid through five use cases, covering common energy demand scenarios at medium and low voltage, as well as a wide range of applications and functionalities.

The technologies applied include energy storage and smart metering devices, PV home panels, heating, ventilation and air conditioning of public buildings, the streetlighting and the optimised heating for a public aquarium, using heat pumps and large thermal storage tanks.

Thus, NETfficient will be demonstrated in these 5 use cases:

peak shaving and ancillary services in the market

A combination of energy management system and energy storage will balance out peaks of the energy demand and availability of renewable energy. Thus, the network performance and grid stability are improved and sustainable energy is made available at any time.

Homes

40 Homes have been equipped with PV-systems energy generation units, smart meters and different energy storage solutions/systems. The energy consumption and generation of the homes is balanced out through the home‘s connection to the NETfficient Energy Management Platform (DERMS).

Buildings

Five public buildings are being supplied by a PV combined with different energy storage solutions/systems. Solar energy is being generated on the rooftops, and in case of an energy surplus, the energy is fed into the electricity grid.

Public Lighting

Smart street lighting is powered by locally produced energy from PV modules on nearby buildings, smart meters and storage batteries. The energy supplied by the sun during the day is thus being used for lighting during the night.

Aquarium water temperature regulation

Maintaining Borkum’s seawater aquarium at a constant temperature using PV energy combined with thermal energy storage.
