The state has witnessed major strides in wind energy generation, with large scale project development commencing from the mid-90s. These Wind Power Plants (WPPs), installed at the outset of wind tapping, were located at wind-rich sites. These have now reached the end of or close to the end of their stipulated lifecycles. Most of these early machines are of low capacities (<500kW) and smaller hub heights (25-30m), resulting in underutilization. These aging turbines often result in low...
