<div style="text-align: justify;">
<span style="font-size: large;">Though net capacity addition <b>in wind</b> power generation for India in FY 19 was less than FY 18 in thermal also, dismal additions in renewables raises alarm bells. In FY17, 5.5 GW of wind was added and next year FY18 saw just 1.7 GW being added. Next year in FY19, situation became worse with only 1.4 GW got added. India is still 80% away from 2022 target of 60 GW. Increasing land acquisition and CUF declaration timelines to 3 years might help the situation in FY20, but DISCOMs remain major bottlenecks.</span></div>
<div style="text-align: justify;">
<span style="font-size: large;"><b>In solar</b>, FY 19 added only 6.5 GW compared to 9.4 GW in FY18. High import duties on Chinese modules could be one of the reasons. Though decreased Chinese modules have been substituted by increase in import from Singapore and Thailand. </span></div>
<div style="text-align: justify;">
<span style="font-size: large;">India has already crossed 30 GW mark in solar and in FY 23 likely to surpass wind installations ( 37 GW presently), but still far away from 100 GW target for 2022. Recent SECI tender for 2GW CPSU make in India SPV did not do well (only 1.2 GW offered). </span></div>

<span style="font-family: Arial, Helvetica, sans-serif;"><b>WATER CONSUMPTION--CONVENTIONAL POWER PLANTS</b></span><br />
<span style="font-family: Arial, Helvetica, sans-serif;">Technology gallons/kWh liters/kWh<br /> Nuclear 0.62 2.30<br /> Coal 0.49 1.90<br /> Oil 0.43 1.60<br /> Combined Cycle 0.25 0.95</span><br />
<span style="font-family: Arial, Helvetica, sans-serif;">Small amounts of water are used to clean wind turbine rotor blades in arid climates (where rainfall does not keep the blades clean). The purpose of blade cleaning is to eliminate dust and insect buildup, which otherwise deforms the shape of the airfoil and degrades performance.</span><br />
<span style="font-family: Arial, Helvetica, sans-serif;">Similarly, small amounts of water are used to clean photovoltaics (solar) panels. Water use numbers for these two technologies are as follows:</span><br />
<span style="font-family: Arial, Helvetica, sans-serif;"><b>WATER CONSUMPTION--WIND AND SOLAR</b></span><br />
<span style="font-family: Arial, Helvetica, sans-serif;">Technology gallons/kWh liters/kWh<br />Wind [1] 0.001 0.004<br />Solar [2] 0.030 0.110</span><br />
<span style="font-family: Arial, Helvetica, sans-serif;">Wind therefore uses less than 1/600 as much water per unit of electricity produced as does nuclear, and approximately 1/500 as much as coal.</span><br />

<div style="text-align: justify;">
<span style="font-family: Arial,Helvetica,sans-serif;">GOI ( MNRE ) has prepared a draft of mission Wind Power !</span></div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
<span style="font-family: Arial,Helvetica,sans-serif;">Following are the plans:-</span></div>
<ul style="text-align: justify;">
<li><span style="font-family: Arial,Helvetica,sans-serif;">Generate capacity of 100 Gw of wind power by 2022.( Presently than 20 GW). </span><br /><span style="font-family: Arial,Helvetica,sans-serif;">This will be an investment of over Rs 10 lakh crore.</span></li>
<li><span style="font-family: Arial,Helvetica,sans-serif;">The potential is estimated at 300 Gw. </span></li>
<li><span style="font-family: Arial,Helvetica,sans-serif;">Extend the ‘generation based incentive for project developers for five years.( Will cosr Rs 18,000 Crore)</span></li>
<li><span style="font-family: Arial,Helvetica,sans-serif;">This ‘wind energy mission’ will be a part of the <a class="storyTags" href="http://www.business-standard.com/search?type=news&q=National+Action+Plan+For+Climate+Change" target="_blank">National Action Plan for Climate Change </a>(NAPPC).</span></li>
<li><span style="font-family: Arial,Helvetica,sans-serif;"> Finance minister Arun Jaitley is likely to announce a slew measures in
his budget including a 10-year tax holiday for wind power producers,
concessions in customs duty and exemption in excise duty for procurement
of technology and equipment for projects.</span></li>
<li><span style="font-family: Arial,Helvetica,sans-serif;">Budget may also announce a ‘National Offshore Wind Energy Policy’
extending further fiscal sops in the form of exemption from service tax
for services like conducting wind resource assessment, environment
impact assessment (EIA), oceanographic study, utilisation of survey
vessels and installation of vessels for these projects.</span></li>
<li><span style="font-family: Arial,Helvetica,sans-serif;">The Budget 2013-14 gave a set of incentives for the wind sector. It
reinstated generation-based incentive (GBI) that had resulted in the
growth of the sector in the past. An incentive of 50 paise is provided
for every unit of electricity generated under the GBI scheme.</span></li>
<li><span style="font-family: Arial,Helvetica,sans-serif;">The government, also reinstated accelerated depreciation (AD) for wind
sector last year. The AD scheme allowed investors to write down up to 80
per cent of the project cost as depreciation when calculating taxable
profits.</span></li>
<li><span style="font-family: Arial,Helvetica,sans-serif;">The withdrawal of AD and GBI schemes in 2012 had for wind energy
projects led to fall in capacity addition with a mere addition of 1,800
MW new capacity in 2012-13 as against 3,000 MW in 2011-12.</span></li>
<li><span style="font-family: Arial,Helvetica,sans-serif;"> </span><span style="font-family: Arial,Helvetica,sans-serif;">About 7000 MW of offshore wind capacity has already been installed
around the world and around the same capacity is under construction. </span></li>
</ul>

<span style="font-family: Arial, Helvetica, sans-serif;"><b>Rated Output Power (ROP):-</b></span><br />
<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span>
<span style="font-family: Arial, Helvetica, sans-serif;">rotor diameter changes the ROP.</span><br />
<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span>
<span style="font-family: Arial, Helvetica, sans-serif;"><b>RPM</b> :- larger dia reduces rotor RPM. </span><br />
<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span>
<span style="font-family: Arial, Helvetica, sans-serif;"><b>Capacity Factor ( CF):- </b>higher capacity factor means higher AEO, but practically CF never goes beyond 40</span><br />
<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span>
<span style="font-family: Arial, Helvetica, sans-serif;"><b>Q) Does wind speed affect AEO?</b></span><br />
<span style="font-family: Arial, Helvetica, sans-serif;"><b><br /></b></span>
<span style="font-family: Arial, Helvetica, sans-serif;">Surprisingly the answer is NO !</span><br />
<span style="font-family: Arial, Helvetica, sans-serif;">This is because AEO is calculated upon average wind speed, which is already accounted for in CF.</span><br />
<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span>
<span style="font-family: Arial, Helvetica, sans-serif;"><i>Maximum Tip Speed that can be obtained is 70-80 m/s.</i></span><br />
<span style="font-family: Arial, Helvetica, sans-serif;"><i><br /></i></span>
<span style="font-family: Arial, Helvetica, sans-serif;"><i>Cut in wind speed for most of the turbines is 5 m/s and cut out is 25 m/s </i></span><br />
<span style="font-family: Arial, Helvetica, sans-serif;"><i><br /></i></span>
<span style="font-family: Arial, Helvetica, sans-serif;"><i>O & M costs can be taken as 8 % of annual gross revenue.</i></span><br />

<span style="font-family: Arial, Helvetica, sans-serif;">Well, the fact is after withdrawal of AD ( Accelerated Depriciation) and GBI( Generation Based Incentive), wind energy scene in India is dull.</span><br />

<ul style="text-align: left;">
<li><span style="font-family: Arial, Helvetica, sans-serif;">Even though revised estimated wind energy potential in India is 102 GWe ( @80m hub height), govt's emphasis on solar energy will not let this potential be utilised. </span></li>
<li><span style="font-family: Arial, Helvetica, sans-serif;">There are 46 types of tubines manufactured in India. ( annual capacity is 12000 MWe)</span></li>
<li><span style="font-family: Arial, Helvetica, sans-serif;">Induction Genearators, Optislip Induction Generators , Doubly Fed Induction Generators, and hybrid generators ( single stage gear box + synchronous generator) and squirrel cage Induction Generators ( with stall turbines for low wind conditions) have been used in India.</span></li>
<li><span style="font-family: Arial, Helvetica, sans-serif;">Hardly any Class I sites are left for development.</span></li>

<li><span style="font-family: Arial, Helvetica, sans-serif;">ETI has given contract to Blade Dynamics for setting up.</span></li>
</ul>

<span style="font-family: Arial, Helvetica, sans-serif;">India having such a long coastline can expect 100000 such turbines, That becomes 1000 MW of wind power for India. !</span></div>
