October 8, 2024 – At Withthegrid, we are excited to announce that the Teleport Gateway now supports control logic for participating in Enexis’ ZonBalans initiative.

This development opens up new possibilities for solar park owners to maximize their energy production while keeping the grid non-congested.

What is ZonBalans?

Due to grid congestion, many solar asset owners face limitations in feeding excess energy back to the grid, often leading to wasted solar energy and missed revenue.

That’s why Enexis developed the ZonBalans program – an initiative allowing solar producers to feed-in their surplus energy outside of peak feed-in times, even if they’re on a waiting list for (extra) feed-in capacity.

💡 Enexis estimates that participants can feed up to 70% of their otherwise unused solar energy back into the grid. You can evaluate your potential yield with ZonBalans using the Enexis calculation tool.

When can I return energy to the grid?

The short answer: when the grid is not full ; the longer answer: it depends on the capacity you’ve agreed on in your contract and how much sunlight there is.

  • If the sun intensity is below 50% of its maximum level, you can send the unused power back to the grid, but only within the limits of your Zonbalans contract.
  • If the sunlight is stronger (above 50% of its maximum intensity), the amount of energy you can send back will be gradually and automatically reduced.
  • If sunlight reaches 75% intensity (975 W/m²), you won’t be able to send any energy back at all.

If you already have an agreement with Enexis for feeding energy back into the grid, that part won’t change. Only the extra capacity you added with ZonBalans will be limited depending on the amount of sunlight.

How can I get started?

Enrollment in ZonBalans is conducted in rounds. If you’re on the waiting list for return capacity and connected to Enexis, you’ll receive a registration link when a round opens.

To qualify, you’ll need:

  • A grid connection of 1750 kVA or smaller
  • Direct feed-in capability (battery storage systems are not allowed)
  • A sensor that measures solar output, and a controller such as the Teleport, to manage the automatic curtailment.
