Run-of-River Origin

Run-of-River Origin

Run-of-River provides documentation showing that the energy is produced using the natural river flow, rather than reservoirs or water storage.

We recommend this product if you prefer that your electricity is produced without reservoirs influencing the landscape and eco-system, and without the use of stored water causing problems to the water flow in the river system.

This way of producing energy reduces the environmental impact related to hydro reservoirs. The energy production will vary based on the river flow. There are limited ways of adjusting the production to the varying energy demand. This production form will therefore be part of the base-load in the electricity market.

ECOHZ can offer offers Run-of-River Origin to customers buying renewable energy with Guarantees of Origin. In addition, Guarantees of Origin can be selected with different technologies, ecolabels and standards, and power plants.
