STRESSING THE need for creating a hybrid combination of wind energy and hydro power in India, Henk Polinder of The Netherlands emphasised that India could generate a large amount of electricity through offshore wind energy plants.
A Ph.D in electrical engineering and an authority on wind energy, Polinder is presently in Bhopal to attend the International Conference on `Wind Energy: Trends and Issues’ (WETI-2006) at the National Institute of Technical Teachers Training and Research (NITTTR).
Talking exclusively to the Hindustan Times today, Polinder stated that being a developing nation India should aim at optimum utilisation of its abundant alternative energy sources. Polinder said that hydropower and wind energy were both renewable and controllable sources of energy and could form a great hybrid combination.
He asserted that India had immense potential to create electricity from sources of alternate energy specially wind. “Being endowed with a vast coastline, India can create huge quantum of electricity from offshore wind power plants,’’ he maintained.
He stated that since the electricity produced through wind power was proportionate to the wind velocity, going offshore could be a more fruitful option. “Offshore winds have higher speeds than on land and thus the amount of electricity generated would also be more,’’ he reasoned.
Although agreeing that setting up offshore wind plants was technically more difficult and almost twice as expensive, Polinder added that end results were very promising.
“Offshore plants generate at least one-and-half times more electricity than onshore and that makes them commercially viable,’’ he maintained.
Moreover, pointing to India’s large population, Polinder mentioned that finding vast open lands with optimum wind velocities was easier said than done. “Setting up wind energy projects was not possible in densely populated areas,’’ he said.
“Therefore going offshore was all the more necessary besides being a more viable option for India,’’ he reasoned. Polinder is currently working as Associate Professor, Electrical Power Processing, at the Delft University of Technology, The Netherlands. He is the author and co-author of over 50 papers and is credited with designing a direct-drive generator for wind turbines.
His main research interests are design aspects of electrical machines for renewable energy and mechanical applications. This is his first trip to India and his paper on ‘Wind Turbine Generator Systems’ is one of the important invited papers at this conference.
