1. 1. Wind Resource Assessment

Wind measuring stations

Wind resource stations are turn-key systems for wind-resource assessments and power performance. These stations have a wide range of devices for measuring wind speed, wind direction, air density, air temperature and incidence of solar radiation.

We operate a network of national reference stations, which have been positioned in promising wind resource sites. We have compiled this information into a single database, which is capable of profiling historical wind data as well as current wind data.

A comprehensive wind resource assessment with updated and reliable information is required for policy makers to initiate necessary strategic actions and developers to develop power generation projects. Resource assessment for Sri Lanka will be done by using satellite data in the WASP software. Results from these modelling will be verified against the ground measurement data.


  • Gathering the necessary input data and error correction
  • Analyse the data and model the data based on WASP software
  • Verify the results with ground measurement data compilation
  • Publishing of the report


  1. 2. Hydro Resource Assessment

The Hydro Resource Atlas for the country is important for policy making and development of hydro energy resources. This provides a database to facilitate the site selection process. The resource availability has already been mapped, which will be scaled up to incorporate the overall hydro resource assessment island wide and would be published in the near future.


  • Verification of the model developed using the performance monitoring results
  • Compilation and publishing of the report


  1. 3. Wave Energy Resource Assessment

Sri Lanka as an island, has been observed as a good candidate for wave energy. An assessment on wave energy resources is conducted in collaboration with the University of Peradeniya. Sea wave patterns will be studied using the available field data obtained from local and foreign institutes. Further, a wave characteristic model for Sri Lanka will be developed and the resource potential assessment will be carried out using the particular wave characteristic model.


  • Preparation of wave energy characteristic model
  • Validation of the model
  • Conducting the wave energy resource assessment


  1. 4. Solar PV Research - Research and Development

Studies on technological interventions related to the enhancement of solar energy absorption are carried out in collaboration with the University of Peradeniya. Research work is nearing completion now. Further, an analysis on piloting the model developed for energy efficient utilisation of solar PV through a DC microgrid will be conducted as way forward to this project.


  • Finalisation and demonstration of DC micro-grid model with solar PV
  • Finalisation of forecasting model for solar PV
  • Looking into the possibility of implementing a pilot project using the outputs of the micro grid


  1. 5. Wind Power Development

With the understanding that the country has a high wind energy potential, and as different modalities of using solar power has paved the way to increase the solar power installation capacity, it is timely that possible optional approaches for wind power development are looked into. Some initiatives have already been made in connection to small scale wind turbines. Some other long-term intervention possibility will be off-shore wind power development. Possible interventions in these lines will be made with a view to having diverse wind power development approaches.


  • Registration of small wind turbine suppliers
  • Installing a wind measuring mast in Hambantota
  • Analysis of generation data with measured data
  • Conducting preliminary study on offshore wind development in Sri Lanka
  • Conducting an analysis on wind power plant performance
