Viability of Introducing Wind Energy as a Renewable Energy Source in Sri Lanka

Wind power has become one of the world’s fastest growing energy sources. The technology is becoming more and more sophisticated in terms of efficiency, cost effectiveness and ease of installation. Especially small wind turbines are a viable alternative for the areas that have no access to electricity. During last few decades, thermal and hydro plants were the dominant energy contributors and utilization of renewable energy resources was relatively small. The steep rise in oil prices depicts the importance of switching to renewable sources which are quite environment friendly and cost effective.

Certain technical and economical issues have to be properly addressed while overcoming the barriers in introducing this novel energy source. The near-term potential wind power capacity expansion is limited by the electricity transmission infrastructure. CEB estimates that grid is unable to accommodate additional wind capacity more than 7% of the peak load which is approximately 100MW. Moreover CEB emphasizes that installing more than 20 MW

of wind capacity in any given area may adversely impact local grid stability and power quality. To overcome these constraints, improvements to the infrastructure along with grid impact studies should be conducted.
Because of the intermittency and variability of the wind, conventional power plants must be kept running at full capacity to meet the actual demand for electricity. Most cannot simply be turned on and off as the wind dies and rises and the quick ramping up and down of those that can be would actually increase their output of pollution and carbon dioxide. Electricity generation from wind fluctuates greatly, requiring additional reserves of "conventional" capacity to compensate; high-demand periods of cold and heat correspond to periods of low wind; only limited forecasting is possible for...
