Archimedes Screw turbine

Home > Services & Products > Archimedes Screw turbine

The Archimedes Screw Company (TASC) has designed and built a revolutionary new Hydroelectric Turbine based on the Archimedes Screw principles.

It is a fish friendly, efficient device for converting the potential energy in water to electricity. ​ The TASC turbine is made from reinforced plastic and is suited to smaller, domestic sites producing less than 15kw.

The Turbine is designed and manufactured in UK and is easily transported and installed with minimal construction works. There are Archimedes Screw Turbines currently available in the market, but these are made from metal and are thus expensive to manufacture, transport and install. They are suited to large scale sites where you might hope to generate more than 50Kw. The Archimedes Screw Turbine is the turbine of choice of the Environment Agency, due to its low impact on the environment.

Hydro energy assessment.

​​Scoping Study to include the following

  • Site surveys, 0.5 days
  • Flow data analysis using the "low flows" software package
  • Energy generation analysis (using on-site measurements and data)    
  • DNO (district network operator) power connection assessment (G83
  • small scale embedded generation connection) 0.25 day
  • Basic financial analysis (FIT, IRRs)  0.25 day
  • Scoping study write-up, 0.5 days

Total cost for this Scoping study is normally £600 plus exceptional travel expenses.

Abstraction license application.

The Abstraction licence application is the most important part of the consents for the  development of the hydro project. The application will include the following:

  • Scheme details
  • Water resource considerations
  • Fisheries considerations
  • Flood risk considerations
  • Planning considerations


PureNRG will manage and install of the Archimedes screw turbine once all appropriate consents have been granted.

  • Ground works
  • Install
  • Testing and commissioning
