					</table><p>Four years after the disconnection of Greenko Maha Wind Energy’s (<a href="https://www.greenkogroup.com/windpower.php" target="_blank" rel="noopener">Greenko</a>) 2 MW Wind Turbine Generator (WTG), the Appellate Tribunal for Electricity (<a href="https://aptel.gov.in/en" target="_blank" rel="noopener">APTEL</a>) has ordered its reconnection to the grid.</p>
<p>APTEL also directed the Maharashtra State Electricity Distribution Company (<a href="https://www.mahadiscom.in/en/home/" target="_blank" rel="noopener">MSEDCL</a>) to sign a Power Purchase Agreement (PPA) with Greenko within two weeks and allow reconnection within one week from the PPA signing.</p>
<p>The Tribunal said MSEDCL must issue credit notes for the energy injected from the WTG into the grid from the date of commissioning and disconnection.</p>
<p>It noted that the WTG should be deemed registered with the Maharashtra Energy Development Authority (<a href="https://www.mahadiscom.in/en/home/" target="_blank" rel="noopener">MEDA</a>) on November 23, 2015, and a formal registration certificate should be issued in a week.</p>
<p><strong>Background </strong></p>
<p>The Maharashtra Electricity Regulatory Commission (<a href="https://merc.gov.in/" target="_blank" rel="noopener">MERC</a>) ordered the Maharashtra State Load Despatch Centre (MSLDC) to disconnect the 2 MW WTG located in Sangli district in Maharashtra because Greenko did not execute a PPA with MSEDCL.</p>
<p>Greenko set up 17 WTGs in the Sangli district in 2015. Each WTG had an installed capacity of 2 MW. Sixteen of the 17 WTGs were covered by PPAs signed in 2017. Eleven were commissioned on October 31, 2015, and the PPAs were signed on March 22, 2017.</p>
<p>Five WTGs were commissioned in March 2017, and the PPAs were executed in August 2017. The last 2 MW WTG was commissioned, but the PPA was not executed. The PPA was not signed due to a delay in issuing a certificate of registration from MEDA which had withheld the registration because the WTG was erected near the road and against micrositing guidelines.</p>
<p>A joint inspection with the petitioner, MSEDCL, and MEDA found that the distance between the WTG and PWD road was above the minimum required, i.e., 157.5m.</p>
<p>The WTG was commissioned in 2015 after getting permission from MEDA and MSEDCL. It generated power until 2020 without receiving objects from MSEDCL and MEDA. For some time, MSEDCL also issued credit notes for the power supply from the WTG. However, after five years of injecting power, the WTG was disconnected.</p>
<p><strong>Commission’s Analysis</strong></p>
<p>The Tribunal observed that the PPA was not signed due to MEDA&#8217;s ‘casual and unwarranted’ approach, for which the petition cannot be at fault. The petitioner also injected power into the grid without any objection from MSEDCL, MSLDC, or MEDA.</p>
<p>Hence, the tribunal ordered the WTG to be registered with MEDA on November 23, 2015. It ordered MEDA to issue a formal registration certificate to the Based on a previous MERC order, it was held that a generator could not feed electricity into the grid without having consent / contractual agreement with the distribution licensee and without approvals/scheduling of the power by the state load despatch center, and injection of such energy by the generator is not entitled to payment.</p>
<p>The Tribunal ruled that MSEDCL cannot evade payment to Greenko for the power received in its grid.</p>
<p>In October 2024, the APTEL <a href="https://www.mercomindia.com/aptel-rebukes-merc-force-majeure-grounds" target="_blank" rel="noopener">reprimanded</a> the MERC for failing to conduct a thorough, case-specific examination of a petitioner’s grievances and provide clear reasoning when applying precedents.</p>
<p>In the same month, APTEL <a href="https://www.mercomindia.com/banked-energy-cannot-units-of-the-same-company-aptel" target="_blank" rel="noopener">ruled</a> that a company&#8217;s banked energy at one facility cannot be adjusted against the electricity consumption of its other units.</p>

If there is no de-rating of WTGs up to the stipulated extreme temperature at the site, their full capacity will be considered when determining connectivity.</p>
<p>In hybrid wind-solar projects, the combined capacity of wind turbines and solar inverters at the extreme temperatures specified by the CEA will determine grid connectivity.</p>
<p>These directives followed a meeting held by the CEA to address pending applications for grid connectivity (CON-4) and Facility to Connect (FTC) approvals for wind power projects. The meeting was convened in response to concerns the Wind Power Producers Association raised regarding difficulties in securing these approvals.</p>
<p>The challenges primarily arise from stringent conditions that require wind turbines to operate without de-rating at the extreme temperatures specified by CEA&#8217;s procedures for wind locations across India.</p>
<p>As of the latest data, ten projects with a combined connectivity capacity of approximately 3,000 MW are awaiting approval. They include three wind power and three wind-solar hybrid projects with a total capacity of 1,995.9 MW in the Southern Region and four wind power projects with a combined capacity of 947 MW in the Western Region.</p>
<p>During the meeting, CTUIL representatives explained that the IEC 61400-1 standard, which applies to wind turbines, sets the normal operating temperature range between -10°C and +40°C, with an extreme range of -20°C to +50°C. They discussed whether the reduced efficiency of turbines at 40°C should be considered when determining grid connectivity.</p>
<p>CTUIL officials emphasized that while IEC standards are globally recognized, CEA&#8217;s regulations require adjustments to account for Indian conditions, including local temperatures. Wind turbines must be designed to withstand the harsh environmental conditions specific to their locations.</p>
<p>Grid-India emphasized that wind turbines must meet IEC standards while also being capable of operating under the severe conditions expected at their sites, even for specialized turbines designed for specific environments.</p>
<p>India <a href="https://www.mercomindia.com/indias-wind-energy-installations-fell-32-yoy-in-q2-2024/" target="_blank" rel="noopener">added</a> 770 MW of wind energy capacity in Q2 2024, down 32% year-over-year from 1,139.9 MW in Q2 2023.

NTPC Issues Tender for 60 MW Wind and 130 MW Solar Hybrid Project in Karnataka

<p>The Ministry of New and Renewable Energy (<a href="http://www.mnre.gov.in/" target="_blank" rel="noopener">MNRE</a>) has charted a course of action for wind turbine generators (WTGs) to follow in order to get low voltage ride through (LVRT) certification.</p>
<p>MNRE <a href="http://mnre.gov.in/sites/default/files/webform/notices/OM-WTG-CEA-RLMM_01032018.pdf" target="_blank" rel="noopener">issued</a> the course of action as part of an order that pertains to the compliance of WTG models to the technical standards of the Central Electricity Authority (CEA) for grid connectivity.</p>
<p>The proposed course of action comes after MNRE examined the issues and difficulties WTG manufacturers face in obtaining their needed statements of compliance (SoC) or conformity statements (CS) within the stipulated time period.</p>
<p>According to MNRE, self-certification for compliance with CEA certification standards will be accepted for WTG manufacturers in the Revised List of Models and Manufacturers (RLMM) until March 31, 2019.</p>
<p>To be included in the RLMM, WTG manufacturers can apply for the LVRT certification to any internationally accredited testing body or the National Institute of Wind Energy (NIWE) for testing by March 15, 2018.</p>
<p>For WTG models for which self-certification has already been provided, a certificate from NIWE must be obtained to demonstrate their compliance with the technical standards of the CEA.</p>
<p>During the self-certification period, the RLMM list will have two tables, one will be for wind turbines that have a valid SoC/CS and the other will be for self-certified wind turbine models for which NIWE certificates have been issued.</p>
<p>If discrepancies are found in the compliance of a self-certified wind turbine model, the original equipment manufacturer (OEM) will be barred from installing wind turbines in India for five years, the wind turbines will be disconnected from the grid, and an additional penalty of ₹20 million (~$306,848) will be levied.</p>
<p>Stall regulated wind turbines and wind turbines with capacities of less than 500 kW that are connected at voltage level of 22kV/11kV and below are exempt from submitting SoC/CS documentation to demonstrate their compliance with CEA technical standards for their connectivity to the grid.</p>
<p>In 2017, Mercom <a href="https://mercomindia.com/solar-top-renewable-source-india-2017/" target="_blank" rel="noopener">reported</a> that wind was the second most installed power source in India after solar, and accounted for 19.6 percent of new installations. Solar and wind together made up for almost 65 percent of new generation capacity last year.</p>
<p>Renewable energy capacity additions continue to gain momentum in India and now account for 19.4 percent of India’s total capacity mix, according to data compiled by <a href="https://mercomindia.com/research/" target="_blank" rel="noopener">Mercom India Research</a>.</p>
