Mahaweli Complex THAMBAPAWANI WIND POWER STATION
Thambapavani Wind Power Station is a 100MW wind farm that operates on semi-dispatchable mode, with a power collector system of an underground cable network. The Dispatch Control Center is equipped with park control facilities and integration with the National System Control Center. The objective of the project is to promote large-scale wind power in Sri Lanka to meet the Government’s renewable energy policy targets, reduce fossil fuel-based power generation for economic sustainability, promote energy independence by diversifying generation options, provide green energy at a substantial cost for environmental sustainability, and benchmark wind power project development in Sri Lanka in technology and pricing. The Thambapavani Wind Power Station is located along a 12.5km land strip on the southern coast of Mannar Island. The main service road connects to other access roads, approximately 150ha of land is acquired for the WTGs and accommodation and other buildings. The administrative building is located adjacent to the Nadukuda substation, and the main control and SCADA are established in the Nadukuda substation.
Total installed capacity of 103.5MW, an annual energy production of 404 GWh, and a total investment of USD 135 million from ADB. The cost per kWh is approximately 4.00 US Cents, including taxes. The project will result in a CO2 saving of 275,000 MT/year and savings of 100 million liters per year of fossil fuel burning. The Wind Turbine Generators used in the project are Vestas 126 3.45MW with low noise levels, and 62.5m length blades with conical steel towers with marine-class protection. The SCADA system is a fully pledged remote control system, and the bird RADAR is integrated with the turbine control for selective shutdown. The foundation of the turbines uses in-situ pile foundations with raised pile caps. The key features of the project are 30 Wind Turbines, UG cable network, access roads (20km other roads), wind power forecasting, power dispatch (Semi-dispatchable), noise mode operation, and bird detecting & selective shut down.
The Thambapavani Wind Power Station is a significant renewable energy project located in Mannar, Sri Lanka, aimed at reducing the country’s reliance on fossil fuel-based power generation for sustainable development. With a total installed capacity of 103.5MW, the wind farm is expected to generate approximately 404GWh of clean electricity annually for the 20years of operation. The project was implemented to promote large-scale wind power and meet the Government’s renewable energy policy targets, while reducing carbon emissions.
The project is equipped with Wind Turbines, underground cable network, and dispatch control center with park control facilities, allowing for semi-dispatchable power generation. The wind turbine model is Vestas 126 3.45MW with low noise levels and 62.5m length blades, and also includes a bird collision avoidance system and wind power forecasting facility. The main control and SCADA system is established in the Nadukuda substation, while the administrative building is located adjacent to it.
