The 45MW waste wood power station is planned to be built by BWSC and Aalborg Energie Technik (AET) on the River Thames near to London.
Under the contract, Alstom will perform project specific design, engineering and manufacturing in collaboration with the UK team.
The contract follows two other deals signed by Alstom and BWSC earlier this year, for the delivery of 23MW and 50MW turbines for projects located in Widnes and Snetterton.
Alstom industrial steam turbines vice-president Daniel Wahler said: "This is our fifth contract with BWSC in the UK, all for different sized turbines, showing the advantages of our modular offering to ensure we can offer the customer a GRT turbine that suits the specific requirements."
According to Alstom, the GRTs are preassembled and lead to cost efficient installation and commissioning. They have been optimized to maximize power production, covering renewable and traditional fuel types.
The Tilbury plant will have an annual power production capacity 300GWh, which is enough to power around 80,000 homes.
Planned to be commissioned in July 2017, the facility is expected to use around 2.7 million tons of renewable wood pellets annually, to be sourced primarily from the South East US, Canada and Europe.
