The FlexMeasures platform

A free platform for real-time optimization of flexible energy.

Energy flexibility is crucial for the energy transition, and it is becoming crucial for the strategy of energy service companies, as well. But it requires serious data engineering and data science, to forecast and schedule energy assets like solar panels and batteries.

We have decided to open source our existing work on energy flexibility, as the FlexMeasures platform.

What are the advantages of using an open source energy flexibility platform?
  • Getting a head start has never been easier – use 26K lines of code.
  • We operate fully transparent ― read our code
  • You make the autonomous choice whether to self-host or subscribe to our SaaS offering (opening soon)

By using the FlexMeasures platform, our customers make use of asset flexibility, so that assets are turned on when the energy mix in the grid contains the most renewable energy (e.g. when the sun is shining). Alternatively, FlexMeasures helps to control batteries so that renewable energy can be used at a later time.

FlexMeasures is versatile as it fits many energy systems, like off-grids, mini-grids, buildings or aggregations thereof. Plus, we can extend FlexMeasures with custom smart control decisions to fit to your needs (e.g. scheduling or predictive maintenance).


Connect sensors to our APIs, tag & group assets (e.g. by building), collect weather and market prices.


View insightful dashboards, receive custom alerts if data is abnormal.

Custom planning

Based on your priorities, make data-driven decisions computed by smart algorithms. Think asset scheduling recommendations or predictive maintenance advice. If needed, take weather forecasts and market prices into account.


Forecasts made by machine learning models are added to the database in real time.


A more detailed view


An online dashboard shows maps, graphs and an order book to act on new intel.

Asset management

Manage their assets manually through the dashboard or automatically through the API. Group them to view aggregated data (e.g. per building or microgrid)


By consisting entirely of open-source digital technologies, your platform will gain new feature opportunities at no cost.


The API design follows the Universal Smart Energy Framework (USEF), which provides a strong and widely accepted architecture to define roles and processes in modern smart energy systems, and connect them with markets.


Automatable with APIs

A well-documented Application Programming Interface (API) allows your sensors and other software to communicate with the FlexMeasures platform in an automated fashion.

Monitoring 24/7

Your platform is monitored continuously such that operators can be notified immediately if problems occur.

Robust benchmarking

Insightful evaluation of new prediction models and information sources, by plotting their probabilistic performance against time of day and time ahead.


Your platform is only served over HTTP Secure and uses a secure hashing algorithm to store user credentials.

Predictive analytics

Machine learning models which allow robust forecasts of energy, weather and pricing data are part of FlexMeasures. When we design custom smart schedules we can schedule actions that take risk into account.

Stable codebase

Low technical debt and a high coverage of functionality via automated tests.

Hit the ground running

We’d be happy to discuss your case and how FlexMeasures can create the maximum value for your energy data.
