Power from Alstom is committed to providing a flexible portfolio of reliable, competitive renewable technologies and is now making significant investments in ocean energy technologies, including tidal stream turbines. Reliable – Predictable – Proven Tidal power is a major growth area, with a global potential of up to 100 GW installed capacity. Tidal power has the potential to contribute significantly to the future energy mix of many countries wanting to benefit from renewable, low-carbon forms of electricity generation. The need is immediate. Renewable energy targets now exist in 118...

Development of the Tidal Generation Ltd. (TGL) tidal stream technology begins, with a concept design study for the turbine technology. kW turbine receives its Type C Design Assessment certification from GL Renewables. 500 kW tidal stream turbine demonstrator begin at the EMEC facility in Orkney – averaging 12 hours of operation each day, demonstrating extended running at rated power as tides allowed. The 500 kW tidal turbine became the only tidal device to receive Scottish Renewable Obligation Certificates (ROC). The 500 kW turbine completed its test programme having successfully exported...

Delivering tidal Following our acquisition of Bristol-based Tidal Generation Ltd (TGL) in 2013, we are developing a proven tidal stream turbine technology with a unique low-cost O&M solution. We have dedicated teams in Nantes (France) and Bristol (UK) that are developing tidal technology and look forward to bringing this product to market. Composite blades Main gearbox Main shaft Inspection hatch Electrical skid Buoyant nose Stab mechanism Yaw clamp Pitch gearboxes Alstom’s turbine nacelle consists of a 3-bladed, upstream pitch controlled rotor with an epicyclic gearbox, induction...

technology today Driving down the cost of electricity The challenge for the emerging tidal stream power generation industry over the next decade is to increase the scale, prove the reliability, demonstrate environmental acceptability and reduce the costs of the technology to ensure electricity can be generated at a commercially competitive price. Key benefits RAPID TURBINE DEPLOYMENT AND RETRIEVAL SYSTEM The turbine can be rapidly installed or uninstalled, maximising the time it spends producing electricity and minimising the cost of deployment and maintenance to its operator. We achieve...

An integrated approach to generating power A Partnership for Performance When you choose Alstom as your Original Equipment Manufacturer, engineering, procurement and construction partner or operation and maintenance (O&M) provider, you are buying into a wealth of energy know-how and experience. The long-term performance potential of a tidal array is only partially determined at the manufacturing and construction stages. The best design and construction will be of little benefit if O&M is not fully optimised. That is why Alstom operates a global network of local service centres and offers a...
