Making PV forecasts with the software solution NEMOCS.

Forecasting & Nowcasting Live Data for Accurate Forecasts

As the operator of one of the world’s largest VPPs, we offer a customizable VPP Software as a Service (SaaS) for energy traders, RES portfolio operators and utilities. Our solution allows networking of renewable energies and gaining live data for forecasting and nowcasting. 

Live Monitoring, Forecasting & Nowcasting with NEMOCS

The higher the share of renewable energies in the electricity mix, the more important is a reliable forecasting of their production: Parties with grid responsibility such as DSOs and TSOs require precise information on expected feed-in electricity volumes to maintain stable operation of the infrastrucure transporting volatile and fluctuating volumes of electricity. Any deviations from the predicted volumes must be compensated for in the short term, thus resulting in high system costs. Our SaaS NEMOCS enables you to gain live data from aggregated assets in real time and is therefore the perfect tool for forecasting or nowcasting.


Volatile energy sources such as wind energy and pv can be aggregated in the VPP and monitored via the control system.

Gaining live data

The control system displays and records real-time information on current feed-in and asset status in high-frequency.

Refining data

Tools for substitute value creation and data cleansing ensure highest data quality. Data can be further processed in billing or trading systems.

Case Study 
Trading on Short-Term Markets

In many countries, deviations between forecasted and actual feed-in can be compensated by trading on short-term energy markets. This is exactly what we do as a certified power trader with our 4,000 MW portfolio of PV in Germany. First, we trade the assets on the day-ahead market based on forecasts. On the day of the actual feed-in, deviations from the day-ahead forecast occur. If this deviation persisted, it would have to be eliminated by balancing energy. In order to minimize the need for costly balancing energy, our traders continuously try to close the gap between day-ahead forecasts and actual feed-in. Live data from our assets is essential for this nowcasting process, as it brings the forecast closer to real generation.

Example of forecasting the feed-in of photovoltaic assets.
