Being subjugated for a while, we have many who are not just physically servile, but even mentally to the colonial way of copycat thinking. Instead of trying to follow your masters to the bitter end, it is time to come up with new technology that no body knows. We forget that the suicidal technology we use today as idiots were a cancerous adaptation of ancient Sinhala knowledge with a twist of confusion and gambling. If you cannot, please keep quiet as there are others who may have done it already. Wind is not something green, but an indication of impending disaster in a tropical format, which needs urgent remedies. If you got time, you should think of using power of lightening as a challenge.

This plant has already paid up the cost of project by the generation of power over this time. The plant factor has been close to 10% only. That means it was in operation at its full load capacity for only 10% of the time. It could have been running for more time but at part load. It is equivalent to running at full load for this period of time. The cost of World Bank project included many training to our staff in foreign countries and visit cost of Consultants and others from various countries who came on training to this site. This was a test pilot project. Such a project can now be constructed at very much lower cost to the country. The feed into the grid is at a far end of a long 33KV system and this line from Embilipitya used to trip very often and every time the line trips the Wind Turbines had to be stopped. This coasted more money for maintenance as we had to frequently replace the brakes used to stop the turbines. The sites with better wind regime were too close to the Bird sanctuary and another site was close to the local army airport is the reason for low Plant factor at this site. But we reliably understand that this plant is going to be dismantled for the expansion project of the Hambantota Harbor. All sites in hilly mountainous areas are not allowed for wind projects due to objection from the environmentalist. Even though the Wind Power projects are GREEN in nature the rules of GOSL Environmental Ministry will not allow large wind projects in the said areas of this article. This position has to be corrected Please give publicity to these facts and Keep the Author informed of these so that he can take these matters with GOSL. The Best WIND regime for Sri Lanka are in Mannar and Jaffna areas and we hope that with these areas liberated from the insurgents it is time to go for more projects in these areas as being done in Puttalam area by the Private sector. Please down Load the wind map for Sri Lanka hear http://swera.unep.net/index.php?id=metainfo&rowid=73&metaid=193 We can plan for sites in the sea as done in many places now where there will be more wind but the project will be more costly both to construct and maintain It is left to the Private sector to put up such new projects in areas with good wind regime. CEB will oppose large quantity of wind power in the system as they have to keep that amount of Power capacity as spinning reserve as the wind could stop any time. This is an expensive affair for CEB. It may be only safe to have less than 10% of the Load fed at any time in the system to avoid stability problem of the Grid. SMART GRID technology when becomes available higher percentage of Large WIND and SOLAR Power can be added to the system as these energies are intermittent. The Gris should have energy storage facility which is lacking in CEB system now. The Hydro system can be used as spinning reserve but those plant will waste too much of water when running at low load. The quick reacting Gas turbines can be used as spinning reserves but they consume costly diesel fuel and have to be operated at low efficiency in low load conditions which is very very expensive to the country. He can contact me at gunda12@yahoo.com if he needs further clarification I am retired and now live in Calgary CANADA where we have 2000MW of wind power and all the (LRT) Light Rail Train system is operated with this green energy. Any consumer has the option to purchase the green Energy at an extra cost of $0.02/kWh where the normal cost of electricity is only about $0.09/kWh and the consumer get many more benefits than the feeling that he is not contributing to the Global warming Being the Person under whom the Hambantota Wind Power project was undertaken, wish to comment the following.
