One contract is with the state-run Hindustan Petroleum Corporation (HPCL) for 24 turbines of the S97-120m model, a 2.1MW turbine with a 120-metre steel hybrid tower, suitable for low-wind sites. The company is unable to reveal the location of the project, said a spokesperson for Suzlon.
Suzlon’s contract includes construction of the site as well as a ten-year operations and maintenance agreement once it is commissioned.
The turbine’s steel hybrid tower designed for low-wind sites is one of the highest available, and uses lattice and tubular steel design. The turbine uses a doubly-fed induction generator (DFIG), and the rotor diameter is 97 metres.
This is the third contract to be awarded to Suzlon by HPCL, taking its wind portfolio to 100MW. In 2007, it was awarded a 3.75MW contract for a project in Maharashtra, and another between 2008-10 for 46.75MW in Rajasthan, the company confirmed.
The second order to be announced is from the National Aluminium Company Ltd (NALCO), also a state-run organisation. The contract is for another 24 turbines, also 2.1MW DFIG turbines with 97-metre rotors. But this time the model is the S97-90m, with lower towers of 90 metres. The project size is also 50.4MW.
Suzlon will again develop the site and will operate and maintain the project for ten years. Suzlon already has 50.4MW with NALCO, constructing a site in 2011 in the state of Andhra Pradesh.
The HPCL and NALCO new projects are expected to be completed by April 2018.
Last week, Suzlon announced a 197.4MW turbine contract for 47 turbines each of S97 and S111 2.1MW models for a project in Andhra Pradesh, southern India.
