A Word from Editor Dear Participant of "The Economics of Wind Power"-conference, Here are the papers to be presented on conference, which were sent to us in time. They are now copied for You to serve as basis for discussion. As organizers we decided to experiment with a new land of conference, which is based on panel discussions. All the authors are given an opprtunity to oral and poster presentation. On all sessions, there is an invited keynote speaker, who helds a longer introduction from the subject of the session. Then all the participants of the sessions are given 3-5 minutes to present their wiews shortly and rest of the i session is devoted to panel discussion. This type of conference demands more from all of the participants, but it is also more rewarding. Please become briefly familiar with materials of each session beforehand to have the maximum benefit. You may also prepare some questions from the points, which have remained unclear to You and write them down for the discussion. Oppotumities to mutual discussions with speakers and other participants are provided on panel sessions on Tuesday and Wednesday. Unfortunately we could not receive all of the papers in time for this publication. Therefore we substituted these papers with corresponding abstracts. Papers successfully presented in conference will later be published in normal conference proceedings of higher printing quality. I wish You rewarding and pleasent confererence on behalf of the organizers. Mr. Harri Vihriala, M. Sc. (E.E.) Secretary of Finnish Wind Power Association '\ 111 WIND ENERGY LOOKING AHEAD IN ANDHRA PRADESH (INDIA) Dr. A.Jagadeesh, Vice President (Wind Mills), Advanced Radio Masts Ltd.,7-139, Habsiguda, Hyderabad 500 007, Andhra Pradesh,India. ABSTRACT : Wind activity is catching up very much in India. Andhra Pradesh, a state in southern part of India is poised to set up large Wind Farms . Based on Wind mapping studies, some areas of Anantapur, Cuddapah, Kurnool and parts of Nell ore and Chittoor Districts are found to have good wind potential. Some of the potential wind locations identified in the state are : Ramgiri, Singanamala, MPR Dam (Anantapur Dt.); Payalakuntla (Cuddapah District), Narasimhakonda (Nellore District), Kakulakonda and Narayanagiri (Chittoor Dt.). Already 1e1MW wind farm is in operation in Tirumala and 2 MW demonstration wind farm in Ramgiri. The State Government has also accorded permission to several wind farm developers. The wind Farm capacity estimated at the above sites is about 284 MW. Details of the ongoing Wind Farm projects, estimated output at locations along with economics of power generation discussed in the paper. A1 » ECONOMICS OF GENERATION OF ELECTRICITY BY WIND IN INDIA ABSTRACT Wind energy activity in India is expanding very fast. With the introduction of installed capacity of 3.3 MW during 1986, this has grown to about 250 MW by March 1995, next only to that in USA and Europe. The growth has been phenomenal after 1991 due to the entry of private entrepreneurs who have found that the investments in wind business is profitable and providing quick returns. The wind energy potential in India is estimated to be about 20,000 MW. The target of Ministry of Non-Conventional Energy Sources, Govt of India is 500 MW to be installed by March 97. However, the present trend in growth indicates that the actual installed capacity may exceed this target. The investments in wind business is profitable in India due to various incentives offered by the Central as well as State governments. Major incentives by the Central government are : a) Hundred percent depreciation on investment during first year. b) No custom duty on the import of major components and spares. c) Soft loan upto seventy five percent of the project cost from Central government funding agency of Indian Renewable Energy Development Agency. The incentives offered by State governments vary, however the important ones are : a) Wheeling and banking of power through State electricity grid. b) Selling of power to government or third party. c) Capital subsidy. d) Availability of land on lease for twenty years. e) Sales tax exemption on the sales regular product, etc. Taking into account various factors such as capital cost of installation of windfarms, depreciation benefit, availability of soft loan, sales tax benefit, income due to sale of power, availability of land on long lease, life of machines, O&M expenditure etc., it is shown that the cost of generation of electricity by wind is comparable to and is even cheaper than from conventional sources such as thermal power and the pay back period is about 5 to 6 years. Sensitivity analysis has also been carried out, taking into account the variation in some of the parameters as mentioned above. DR. R.P. GUPTA, DEPUTY GENERAL MANAGER (WIND) CORPORATE R&D, BHARAT HEAVY ELECTRICALS LIMITED HYDERABAD, INDIA - 500 093 A2 ANNEXURE Abstract of paper proposed to be presented by Padmashree Rakesh Bakshi. Chairman, RRB Consultants 8 Engineers" Pvt. Lt. at the EWEA Special Topic Conference on the "Economics of Wind Energy" to be held on September 5-7, 1995 at Helsinki, Finland "The Economics of Establishing a 10 MW Wind Farm in Tamil Nadu, South India" ABSTRACT Compared to conventional sources of energy such as coal and diesel and also due to other factors such as short project gestation, modularity, non-polluting nature of the technology and present overall shortage of power and energy the demand of wind power projects by Private Companies is developing exponentially.
