					</table><p>The Central Electricity Regulatory Commission (<a href="https://www.cercind.gov.in/" target="_blank" rel="noopener">CERC</a>) has adopted tariffs for 1,080 MW of interstate transmission system (ISTS)-connected wind-solar hybrid power projects awarded by <a href="https://ntpc.co.in/" target="_blank" rel="noopener">NTPC</a>.</p>
<p>NTPC <a href="https://www.mercomindia.com/ntpcs-1-5-gw-wind-solar-auction" target="_blank" rel="noopener">selected</a> four bidders: Solalite Power (<a href="https://www.o2power.in/" target="_blank" rel="noopener">O2 Power</a>) with 300 MW at ₹3.35 (~$0.0402)/ kWh, <a href="https://sprngenergy.com/" target="_blank" rel="noopener">Sprng Energy</a> with 250 MW at ₹3.35 (~$0.0404)/ kWh, <a href="https://www.acme.in/" target="_blank" rel="noopener">ACME Cleantech Solutions</a> with 300 MW at ₹3.36 (~$0.0405)/kWh and <a href="https://www.junipergreenenergy.com/" target="_blank" rel="noopener">Juniper Green Energy</a> with 230 MW at ₹3.36 (~$0.0405)/kWh.</p>
<p><strong>Background</strong></p>
<p>NTPC had <a href="https://www.mercomindia.com/ntpc-bids-1-5-gw-wind-solar-hybrid-projects-india" target="_blank" rel="noopener">issued</a> a Request for Selection (RfS) for setting up 1,500 MW of ISTS-connected wind-solar hybrid power projects anywhere in India. The tender was conducted by the <a href="https://powermin.gov.in/" target="_blank" rel="noopener">Ministry of Power</a> on August 21, 2023.</p>
<p>Initially set to close on October 17, 2023, the bid submission deadline saw multiple extensions, finally concluding on November 29, 2023. The process attracted five bidders who collectively proposed projects totaling 1,380 MW, short of the tendered 1,500 MW capacity.</p>
<p>The financial bids were opened on December 22, 2023, followed by an e-reverse auction on December 27, 2023. This competitive process resulted in the selection of four successful bidders for a total capacity of 1,080 MW. NTPC issued Letters of Award to these successful bidders on January 11, 2024.</p>
<p>It requested the Commission to adopt the tariffs discovered by competitive bidding.</p>
<p><strong>Commission&#8217;s Analysis</strong></p>
<p>The CERC examined whether the bidding process followed the government guidelines. NTPC constituted a committee for bid evaluation, which certified that the evaluation criteria were strictly complied with and the process was transparent.</p>
<p>The Commission noted a delay in NTPC approaching CERC for tariff adoption, as required within 15 days of tariff discovery. NTPC attributed this to internal approval processes and being the first tender under the new guidelines.</p>
<p>CERC considered NTPC&#8217;s submission that tariff adoption and PPA/PSA approval are separate processes and that early tariff adoption would provide regulatory certainty and help tie up power with state utilities.</p>
<p>In a departure from past practice, the Commission decided to adopt the tariffs without waiting for the capacity to be tied up under power purchase and sale agreements, subject to NTPC securing these agreements in the future.</p>

Sprng, NTPC, Ayana, O2 Win Railway’s 1 GW Solar-Wind Hybrid Auction

<p>The Solar Energy Corporation of India (<a href="http://seci.co.in/index.php">SECI</a>) has auctioned 480 MW of interstate transmission system (ISTS)-connected wind power projects. This was part of the 1,200 MW tender that was floated under tranche-VII.</p>
<p><a href="https://mercomindia.com/wp-content/uploads/2019/05/eng.png"><img loading="lazy" decoding="async" class="aligncenter size-full wp-image-13570" src="https://mercomindia.com/wp-content/uploads/2019/05/eng.png" alt="" width="634" height="270" srcset="https://mercomindia.s3.ap-south-1.amazonaws.com/wp-content/uploads/2019/05/eng.png 634w, https://mercomindia.s3.ap-south-1.amazonaws.com/wp-content/uploads/2019/05/eng-300x128.png 300w, https://mercomindia.s3.ap-south-1.amazonaws.com/wp-content/uploads/2019/05/eng-624x266.png 624w, https://mercomindia.s3.ap-south-1.amazonaws.com/wp-content/uploads/2019/05/eng-600x256.png 600w" sizes="(max-width: 634px) 100vw, 634px" /></a></p>
<p>Engie emerged as the lowest (L1) bidder in the auction. Malcolm Wrigley, the country manager of Engie India, said, “We have emerged as the lowest bidder by quoting a tariff of ₹2.79 (~$0.0396)/kWh to develop ISTS-connected wind power projects of capacity 200 MW.”</p>
<p>A SECI official confirmed the culmination of the auction adding that the L1, L2, L3 and L4 tariffs quoted are ₹2.79 (~$0.0396)/kWh, ₹2.81 (~$0.0398)/kWh, ₹2.82 (~$0.04)/kWh and ₹2.83 (~$0.0401)/kWh.</p>
<p>According to a market source, ReNew Power quoted a tariff of ₹2.81 (~$0.0398)/kWh to set up 50 MW of wind projects, Sprng Energy quoted ₹2.82 (~$0.04)/kWh to set up 100 MW, and Adani Green Energy quoted a tariff of  ₹2.83 (~$0.0401)/kWh to set up 250 MW but will be awarded only 130 MW.</p>
<p>Mercom <a href="https://mercomindia.com/secis-1-2-gw-wind-tender-undersubscribed/">previously reported</a> that SECI’s tender for 1,200 MW of ISTS-connected wind power projects on a pan-India basis under tranche-VII was undersubscribed by 50%. SECI had tendered the capacity in <a href="https://mercomindia.com/seci-tender-wind-solar-rooftop/">February 2019</a> and fixed a tariff cap of ₹2.83 (~$0.0401781)/kWh for this tender.</p>
<p>If a tender is undersubscribed, 80% of the capacity that has been bid for, is usually awarded. Bids totaling 600 MW had been submitted for this tender and therefore the implementing agency has decided to award 480 MW of ISTS-connected wind projects.</p>
<p>Another market source confirmed that Adani Green Energy has emerged as one of the successful bidders in SECI’s Tranche-VII ISTS-connected wind auction.</p>

<p>Wind tariffs are stabilizing above the ₹2.75 (~$0.0390426)/kWh mark in India, as has been observed from the results in successive wind auctions. The L1 tariff quoted in this auction is ₹0.03 (~$0.0004)/kWh less than the L1 tariff of <a href="https://mercomindia.com/seci-wind-auction-1-2-gw/">₹2.82 (~$0.0400361)/kWh</a> quoted in the auction held by SECI for 1,200 MW of ISTS-connected wind projects issued under Tranche-VI.</p>
<p>The L1 tariff of ₹2.79 (~$0.0396)/kWh discovered in this auction is ₹0.01 (~$0.0001)/kWh less than the L1 tariff of ₹2.80 (~$0.0397)/kWh that was quoted in Gujarat Urja Vikas Nigam Limited (<a href="http://www.gseb.com/guvnl/index.aspx">GUVNL</a>)’s auction for 1,000 MW of grid-connected wind power projects.</p>


Engie’s ₹2.79/kWh Emerges as the Lowest Tariff in SECI’s 480 MW Wind Auction

<p>The Solar Energy Corporation of India (<a href="http://seci.co.in/" target="_blank" rel="noopener">SECI</a>)’s 2 GW Tranche-V wind tender has been undersubscribed by 800 MW.</p>
<p>The shortage of connectivity infrastructure across the country seems to have taken its toll on this tender.</p>
<p>SECI had tendered the capacity in <a href="https://mercomindia.com/seci-tenders-2-gw-ists-connected-wind/" target="_blank" rel="noopener">May 2018</a>. In the recently concluded SECI wind auction for 2 GW, the lowest (L1) tariff quoted by the bidders stood at <a href="https://mercomindia.com/seci-2gw-wind-auction/" target="_blank" rel="noopener">₹2.51</a>(~$0.0386)/kWh.</p>
<p>According to a source whose company is participating in the tender, bids totaling 1,200 MW have been received against the tendered capacity of 2 GW.</p>
<p>ReNew Power, Adani Green, Sprng Energy, and Alfanar each submitted bids for 300 MW, according to the source.</p>
<p>When contacted, a SECI official confirmed that this time around, less number of bids have been received.</p>
<p>The source further said, “Wind has been around for a longer time, and developers in this sector better understand connectivity issues as compared to solar developers. Even the wind tariffs are relatively stable, no fluctuation, no mad dash by developers to execute projects.”</p>
<p>This undersubscription of SECI’s wind tender comes on the heels of SECI’s 2 GW solar tender which was oversubscribed by <a href="https://mercomindia.com/seci-2gw-ists-solar-tender-oversubscribed-1-8gw/" target="_blank" rel="noopener">1.8 GW</a>, highlighting the voracious appetite of developers in India to win large-scale solar projects.</p>
