The Nala Dhanavi Wind Project (Erumbukkal Wind Project); commissioned for operation in 2013, is a Wind Energy Farm with the capacity of 5.1 MW, located in Erumbukudal, Kalpitiya, Puttalam.

The farm features a specification of six Wind Turbines of capacity 850 kW (Siemens Gamesa G58) with a hub height of 65 m and a rotor diameter of 58 m and double fed asynchronous generators. Cutting edge centralized monitoring and command centres closely track output and make required adjustments with minimal human intervention thus ensuring uncompromised power generation efficiency. When operating at peak efficiency, the project will make a saving of 7,000 metric tonnes of CO₂ emissions per annum.
