Ancillary Services

Keeping the grid in perfect balance

Renewable energies are already a central element in the energy mix today. In the future they will be the backbone of our energy supply. This creates new requirements: With the rise of weather-dependent energy sources, fluctuations in the power grid are increasing. A central task in the modern energy industry is therefore to guarantee grid stability at all times through controlling the power infeed and offtake of distributed energy resources (DERs).
Today, not only large power plants can provide ancillary services. Aggregated in a Virtual Power Plant, smaller units with a shorter reaction time can play a vital role in levelling out these fluctuations. Our VPP-solution NEMOCS enables you to network distributed assets and offer balancing services via your own VPP.

NEMOCS: A strong platform for ancillary services


NEMOCS is the perfect tool for networking distributed energy resources: from biogas or natural gas CHPs, to hydro power plants and flexible consumption processes. Aggregated in a VPP, the assets can help stabilizing the grid frequency.

Analysis of energy portfolio


The control system displays and records real-time information on current capacity, storage levels, and standby status of all DER assets. You can see the exact amount of available capacity in your VPP. In addition, it displays external data like grid frequency or market prices.


You can adjust power production, consumption and storage systems depending on grid requirements and thereby achive a stable power supply. The disptach signal which is distributed by NEMCOS can be instructed by you, the VPP operator, or the system operator themselves.

Case Study: Ancillary services for the European grid

As the operator of our own VPP we are active in seven European TSO areas providing balancing services. With our pool of prequalified assets we participate in the auctions of the TSOs. In case of frequency imbalance we’ll receive an order from the system operator requesting a certain amount of control reserve. The algorithm of the VPP decides which asset will provide how much control reserve, based on individual restrictions of the DER assets. The respective units will then be ramped up or down at short notice. The providers receive additional revenue for this service. In addition, they effectively support the energy transition by protecting the grid against the fluctuations associated with volatile energy sources.
