Virtual Power Plants or VPP’s are a new energy management concept that interweaves several energy sources aggregated and managed by a single control system.


Know how they work in this video.


UNITY Integrated VPP platform unleash the power of your portfolio
Typically, clients of our Aggregator facility

Asset Operators: Monitor and manage plant portfolios with real time data and power predictions


Grid Operators: Predictions and estimates of Solar, Wind, Storage,Hybrid inputs towards most of operational grid requirements


Power Traders: Forecast for individual assets, portfolios, and markets. Build your own solution

Unique digital control room for distributed energy resources

Renewable energies present power traders, grid operators and plant operators with complex challenges :

these extend from the fluctuating input from wind storage and solar to the management of many smaller, decentralized power generating assets up to the consideration of different grid levels. Such challenges can be mastered out with Inaccess’s unique flexible software-as-a-service solution.

Our power forecasts and virtual power plant control software are ideally linked to cover the entire process from metering data recovery to delivering perfect scheduling.



*Data Reconciliation,

*Automatic Bidding,

*Dynamic Control for physical Optimization
