The Gatter3 group in Holzwickede (Germany) showcases how self-generated clean energy can be used for electricity and heat right at the source. Thus, a complicated and expensive expansion of the grid connection point can be avoided and, above all, energy consumptions and grid tariffs can be reduced. In the Gatter3 project, the existing PV system, fuel cell, heat pump, battery storage, intelligent street light and charging stations were connected to enable smart control of energy flows. One of the biggest challenges of the project was the integration of different energy producers and consumers from different manufacturers. gridX also integrated the heating system into the energy management system to ensure cross-sector optimization.
gridX offers a holistic energy management system that meets Gatter3's requirements and demands. For Gatter3, the project marks the start of the intelligent connection of all energy sources, consumers and storage. In summary, gridX energy management system allowed Gatter3 to shave peaks, shift loads, and thus cut grid tariffs drastically. The additional integration of the heating system allowed further cost savings, without comprising on comfort. gridX's solution allowed Gatter3 to operate state-of-the-art energy systems on the existing infrastructure – and therefore forego a costly grid connection expansion. gridX enabled savings on three ends: grid expansion costs, grid tariffs and energy costs.
We are already achieving a degree of self-sufficiency of up to 100% at our location in Holzwickede and we are recording energy savings of up to 100,000 kWh per year.
