Wind Curtailment for Pure Energie

Automated Curtailment for the Total Wind Portfolio of Pure Energie

Our Automated Curtailment module (a modular product of our STELLAR platform) optimizes the total wind portfolio of one of the most renewable energy retailers and developers in the Netherlands, Pure Energie. At the moment, the wind portfolio from Pure Energie is over 200 MW and in the coming years, the portfolio will be expanded.


May 2022 - Present





As more and more renewable energy is coming online, the imbalance costs go up and the chance that negative pricing on the energy market will occur is increasing. Besides that, DSOs have an increasing challenge when it comes to managing grid congestion. There are issues at both sides: on the one hand, trading can be optimized, while on the other hand, the local grid can be managed in a more efficient way. Curtailment, temporarily switching off wind turbines, can be a part of the solution.



This is a STELLAR project. In collaboration with the trading team of Pure Energie and the involved OEM parties, Spectral will enable cloud-to-cloud connectivity with the wind turbines. The assets will be connected to our STELLAR platform and as of that moment, our sophisticated energy management system will steer the wind turbines in a fully automated way to curtail.



The automated curtailment service will yield revenue (or rather avoid costs) for every wind farm that is connected to our platform. Once all the wind parks are connected, Pure Energie will be able to optimize its full wind portfolio and further increase the yielding by leveraging curtailment.

With 200 MW of wind capacity, 200.000 households can simultaneously be provided with renewable energy.

At Pure Energie, we like to partner with like-minded and innovative partners that strengthen our current and future value propositions for our customers. Spectral is one of those partners and we are happy to have them on board in our ecosystem.
