January 2020

Solvay, Torrelavega, Cantabria.

The Solvay industrial plant is located in Torrelavega in the province of Cantabria. There, the Saja River derives part of its channel for the industrial process that the plant requires.

Taking advantage of the permit to use the water and a small existing waterfall, we installed 2 parallel Hydroscrews which are able to produce a total of 70kW of power, 35kW each.

Knowing the natural surroundings where the Hydroscrews will be installed is essential. Solvay uses a height of 2 meters and a flow rate of 5 cubic meters per second between the two turbines.

The entire project takes 4 months, counting on the development of all the civil works necessary for its implementation, as well as the development and manufacturing of the turbines which is carried out by MILSA. The civil work is carried out at the same time as the development of the turbines which results in an agile project of the highest quality.

The energy produced will be used to sell to the electrical grid and also for experimental non-domestic self-consumption projects.

 

The turbines have a fish-friendly design, allowing a safe descent of the fish.. 

The size of the buckets and the slow rotation of the turbine (< 50 rpm) allow the fish to descend in a safe manner between the rotor blades. As a result, the hydroscrews are safe and suitable turbines for ichthyofauna, allowing fish to migrate downstream through them.

The return on the investment for the customer lies in the sale of the energy produced by this micro-hydroelectric plant to the electrical grid and it will be redeemed between 7 to 8 years from its commissioning, this became a reality in January 2020.
