Curtailment of Renewable Energies

Wherever the expansion of renewable energies progresses faster than the expansion of the grids, critical situations occur more frequently. For example, an unexpectedly high feed-in of wind or solar energy can overload sections of a grid and thereby endanger the security of energy supply. Our VPP solution NEMOCS enables you to monitor a large number of assets and shut them down if necessary. Thus critical grid situations can be reliably averted.

With more renewable energies in the grid, surplus situations can occur more often - for example in the event of a storm, which supplies a large amount of wind energy. Besides critical grid situations, this can also cause negative prices on the electricity exchange. In these cases, it may be economically viable to curtail decentralized assets at short notice. The figure shows how NEMOCS responds to price signals from the electricity market and immediatly ramps down a windmill. When prices rise, NEMOCS automatically terminates the curtailment. The windmill ramps back up.

As the operator of one of the largest VPPs in Europe, we network thousands of assets in our Next Pool. By supplying balancing services, we’re helping to keep the grid stable and are currently operating in seven European control reserve zones. Our software solution is perfectly suited for providing capacity reserve and trading energy flexibility.
