RES Curtailment
Protect the Power Grid in Case of Excessive Feed-In

As the operator of one of the world’s largest VPPs, we offer a customizable VPP Software as a Service (SaaS) for RES portfolio operators, utilities and system operators. NEMOCS enables you to monitor a large number of assets and curtail them in cases of critical grid situations or negative power market prices.

NEMOCS: A Strong Platform for Curtailment Purposes

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.

Control Volatile Energy Sources

Aggregate a large number of decentralized assets and control them remotely via a central control system.

Connect to Grid Operators

Receive signals from your system operator to curtail or dispatch your renewable energy generation to provide more grid stabilty.

Avoid Charges for Imbalances

Ramp down your renewable electricity production to avoid periods with negative pricing or imbalance of your portfolio.

Case Study
Wind Curtailment When Negative Prices Occur

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 immediately ramps down a windmill. When prices rise, NEMOCS automatically terminates the curtailment. The windmill ramps back up.
