TLS: Archimedean Screw Specialists
TLS Renewable Consulting Ltd has built its own reputation on successful hydro projects since 2020, but also inherits the expertise behind the MannPower brand.
MannPower Hydro Ltd was established in 2004 by Dave Mann. Exploiting his previous career as a technical project manager in seimsic and electrical engineering around the globe, Dave returned to the UK to indulge his lifelong passion for the potential of hydropower. Seeking a viable hydropower solution for a Georgian watermill within an SSSI on the River Derwent in Yorkshire, Dave’s extensive research led him to the Archimedean Screw turbine. With its fish-friendly characteristics and high efficiency rates, the screw was a perfect fit. Dave pioneered its introduction and propagation in the UK via setting up independent consultancy MannPower, which grew to be the senior specialist UK consultancy in Archimedean Hydro Screws.
TLS Renewable Consulting boasts a combined history of having designed and installed many dozens of schemes using screws from several of the leading manufacturers, as well as undertaking a number of waterwheel projects. The TLS team continues to design and procure for new hydro installations throughout the UK and Ireland, as well as providing expert consultancy services and maintenance engineering services for operational hydropower schemes using screws and other technologies.

Engineering Interns
From time to time, we have occasionally engaged summer interns. We are happy to hear from graduate-calibre or experienced hands-on would-be hydropower engineers who show a particular interest in hydropower, in case we have a new opportunity to offer a temporary internship in TLS Group’s engineering operations. For energy analysis and trading, this would be based in Rickmansworth, Herts. For those keen to experience work on engineering projects in outdoor conditions, it would be based in Malton, North Yorkshire.
