The linked power systems of western Denmark and northern Germany are innovative testing grounds for how to achieve reliable and affordable supplies of electricity entirely from renewable energy. Strong cross-border grids, new types of system technology and platforms for local energy exchange are all in the mix. Europe’s regulator is keeping a close eye on progress.
Challenge: Renewable energies do not cause disturbances, but change electricity system behaviour, demanding new approaches to daily operations
Answers: Denmark is boosting the capacity of its cross-border high voltage wires and embedding technology to recreate the system inertia lost when renewables replace central generation. Schleswig-Holstein, Germany wants internal low voltage distribution networks to contribute to security of supply with flexible consumption and generation from local production points
Concern: The European power system is, in some areas, increasingly being operated closer to technical limits
