Kepler Energy was established in 2010 to exploit, with an exclusive licence, an internationally patented 2nd generation tidal turbine developed from 2007 to 2010 by three senior academics at the University of Oxford Department of Engineering Science.

The Kepler turbine is very different to all others on the market - it is larger, scaleable, intrinsically more powerful and patented. The truss configuration of the rotor blades enables a much larger area of flow to be captured per rotor (typically 600 m²) and provides for greater power production than first generation tidal stream turbines (typically 80 m²).

The turbine has been optimised to open up new resources in low tidal stream velocity flows (below 2.5 m/s), the most commonly found current strength in coastal waters across the globe. The rotor is deployed in standardised units within a tidal fence arrangement, with the key advantage of generating revenue incrementally during the construction phase, to provide certainty in realising expected equity returns.

Kepler has no direct economic competitors in providing access to tidal stream resource where first generation turbines are not economic, and represents the first disruptive technology to positively impact on the economics of power production from this predictable source of sustainable energy.
