Committed to the environment

Our goal is to produce renewable, clean and micro-scaled energy without losing sight of building it in a respectful way for our ecosystem.

We provide the renewable energy market  with a sustainable approach with the environment, safe for fish and wildlife.

A continuous search must be made for new ways of producing renewable energy and at the same time, to protect the environment. No matter what the technology is and where the renewable source comes from, it will always be difficult to find the equation that allows for their balance.

We have no doubt that micro-scale hydroelectric power is the most productive venue when depending on capacity factors. They even beat more “traditional” technologies such as solar or wind. However, they all complement each other, forming systems that allow us to build a more sustainable future for the next generations, returning to our planet part of the wealth that it has given us.

The water resource is still abundant, but it has to be treated with rigorous care and this factor is the cornerstone of development. Our engineering and technology facilitate that the flow dynamics do not change or that the available water is wasted. The upstream or downstream flows remain intact.


We create clean energy

The characteristics of the generators developed by Sinfin Energy allow us to look for that balance between renewable energies and respect for ichthyic populations. Our Turbine based on the Archimedes Screw rotates at slow speeds, at a rate of about 30 turns per minute. When fish enter through the top of the machine, they simply descend the screw in large tubs and swim in its lower part, without being disrupted or harmed in any way. The turbulence at the exit of the system is minimal because the water does not accelerate or drift in these channels.

Tiers and fish steps, Fish-Friendly construction


Developing our systems while thinking about the fluvial fauna is, in addition to the philosophy on which we base our engineering, the best way for cost savings from the beginning of the project. Our goal is to build sustainable steps and tiers for fish in all our systems, simultaneously developing and thinking of a quick return on investment.

There are many studies in the matter, all of our systems and technologies are tested, thus ensuring a responsible method for generating profitable and totally clean micro-energies.
