Regulatory Developments in Power Transmission Sector: March 12, 2025

APTEL upholds transmission charges liability for UPRVUNL, UPPTCL

The Appellate Tribunal for Electricity’s (APTEL) ruled on appeals by Uttar Pradesh Rajya Vidyut Utapadan Nigam Limited (UPRVUNL) and Uttar Pradesh Power Transmission Corporation Limited (UPPTCL) against an Uttar Pradesh Electricity Regulatory Commission (UPERC) order dated 24 June 2024. The case involved liability for transmission charges of specific transmission elements developed by Obra-C Badaun Transmission Limited (OCBTL), a transmission service provider under a Tariff-Based Competitive Bidding process.

UPRVUNL challenged its liability for transmission charges of Element 1 of Lot 1 from 30 April 2021 until the operationalization of the Obra-C Thermal Power Station (TPS) switchyard. It argued that it was neither a signatory to the Transmission Service Agreement (TSA) nor was any specific relief sought against it in the petition. However, UPERC ruled that UPRVUNL was a defaulting entity as the delay in commissioning the Obra-C TPS led to the non-utilization of the transmission element.

UPPTCL contested its responsibility for transmission charges of Element 9 of Lot 2 from 10 June 2022 to 26 April 2023, arguing that the 400 kV Jaunpur substation’s delay was due to land acquisition and COVID-19 disruptions. The tribunal upheld UPERC’s decision, stating that as the State Transmission Utility (STU), UPPTCL was responsible for planning and coordinating transmission infrastructure and should have ensured timely availability of interconnection facilities.

The tribunal upheld the UPERC order, affirming that UPRVUNL and UPPTCL must bear the transmission charges for the respective periods due to delays in their infrastructure, which prevented power flow. The appeals were dismissed.

Petition No: APL No. 357 OF 2024 & IA No. 1368 OF 2024 & APL No. 369 OF 2024 & IA No. 1377 OF 2024 & IA No. 1638 OF 2024 | Read the full order here.

APTEL directs MSERC to reconsider MePTCL’s tariff dispute over RoE

The Appellate Tribunal for Electricity’s (APTEL) has ruled in favor of Meghalaya Power Transmission Corporation Limited (MePTCL) in a case challenging the Meghalaya State Electricity Regulatory Commission’s (MSERC) tariff order. The appeal, filed in 2017, contested the MSERC’s computation of Return on Equity (RoE) for the financial years 2013-14 and 2014-15.

The dispute arose when MSERC approved an RoE of Rs. 151.7 million for 2013-14 and Rs. 152.1 million for 2014-15, significantly lower than MePTCL’s claims of Rs. 469.5 million and Rs. 514.5 million, respectively. MePTCL argued that the Commission incorrectly calculated the equity base using Gross Fixed Assets (GFA), contrary to the Tariff Regulations, 2011.

The Tribunal, referencing its earlier judgment in a similar case, found that MSERC failed to consider equity additions resulting from the transfer of assets from the erstwhile Meghalaya State Electricity Board (MeSEB) to MePTCL. The Tribunal emphasized that the equity base should reflect the audited balance sheet or transfer scheme notifications, as per Regulation 101 of the Tariff Regulations.

In its final order, the Tribunal set aside the MSERC’s 2016 tariff order and remanded the matter back to the Commission for fresh consideration, directing it to account for the equity additions due to the transfer scheme. The appeal was allowed.

CERC approves transmission tariff for nine OPTCL lines for 2014-19 period, excludes two lines

The Central Electricity Regulatory Commission (CERC) has approved the transmission tariff for nine non-ISTS (Inter-State Transmission System) lines owned by Odisha Power Transmission Corporation Limited (OPTCL) for the 2014-19 period. The order, dated February 26, 2025, addresses the inclusion of these lines in the computation of Point of Connection (PoC) charges and losses under the 2010 Sharing Regulations.

OPTCL had filed the petition seeking approval for the Annual Fixed Charge (AFC) and Yearly Transmission Charge (YTC) for the nine transmission lines, which carry ISTS power. The lines, ranging from 132 kV to 400 kV, were certified by the Eastern Regional Power Committee (ERPC) as carrying inter-state power. However, two of the lines, the 220 kV Rengali-Rengali and 220 kV Balimela PH-Upper Sileru, were excluded from tariff approval due to lack of power flow during the 2014-19 period.

The CERC determined the tariff based on a normative methodology, considering a 35-year useful life for the transmission lines, as per the Appellate Tribunal for Electricity’s (APTEL) ruling. The capital cost for the lines was derived using historical data from Power Grid Corporation of India Limited (PGCIL), with adjustments for older assets. The O&M expenses were calculated as per the 2014 Tariff Regulations.

The final order allows tariff recovery for seven of the nine lines, with the transmission charges to be adjusted against the Annual Revenue Requirement (ARR) approved by the Odisha Electricity Regulatory Commission. The CERC also directed the ERPC to verify the availability of these lines and link tariff recovery to their operational status.

CERC approves amendment to POWERGRID Ramgarh Transmission Limited’s licence for Fatehgarh-III substation project

The Central Electricity Regulatory Commission (CERC) has approved an amendment to the existing transmission licence of POWERGRID Ramgarh Transmission Limited (PRTL) to include the “Augmentation of transformation Capacity at 400/220 kV Fatehgarh-III PS (Section-1) by 400/220 kV, 1×500 MVA ICT (5th)” project. The amendment was sought under the Regulated Tariff Mechanism (RTM) following an Office Memorandum (OM) issued by the Central Transmission Utility of India Limited (CTUIL) on October 26, 2023.

The project, estimated to cost Rs 581.8 million, aims to enhance the transformation capacity at the Fatehgarh-III substation to meet the N-1 reliability criteria as per the Central Electricity Authority’s (CEA) Transmission Planning Criteria 2023. The augmentation is critical for ensuring the reliable evacuation of power from renewable energy zones in Rajasthan, particularly for projects with a cumulative capacity of 1980 MW connected to the substation.

PRTL, a wholly-owned subsidiary of Power Grid Corporation of India Limited (PGCIL), had previously been granted a transmission licence for other RTM projects. The current amendment allows PRTL to implement the new project under the RTM mode, with the completion deadline set for April 26, 2025. The CERC has directed PRTL to adhere to the timeline and ensure timely execution.

The Commission also noted that no objections were received from the public or beneficiaries following the publication of notices regarding the amendment.

CERC allows Reliance Industries to share GNA with subsidiary, rejects request for STU-connected entities

The Central Electricity Regulatory Commission (CERC) has ruled on a petition filed by Reliance Industries Limited (RIL) seeking permission to allow its subsidiaries and group companies to use its General Network Access (GNA) at the Jam Khambhaliya Inter-State Transmission System (ISTS) substation in Gujarat. The petition was filed under Section 79 of the Electricity Act, 2003, along with provisions of the General Network Access Regulations, 2022.

RIL, which has 1200 MW connectivity to the ISTS substation at Jam Khambhaliya, sought approval to let its subsidiary, Reliance New Solar Energy Limited (RNSEL), use part of its 500 MW GNA allocation starting from October 2024. RNSEL was granted 50 MW GNA, effective from March 2028, but required access before this date. RIL argued that since both companies are connected at the same ISTS connection point, RNSEL should be allowed to utilize its parent company’s GNA under Regulation 15.1 of the GNA Regulations.

CERC ruled in favor of RIL, allowing RNSEL to use RIL’s GNA. The commission clarified that subsidiaries could utilize a parent company’s GNA at the same connection point without requiring a separate GNA, provided they establish the necessary technical and scheduling arrangements. It directed the National Load Despatch Centre (NLDC) and the Central Transmission Utility of India Limited (CTUIL) to develop a procedure within two months to outline the modalities of such GNA sharing.

However, CERC rejected RIL’s request to permit other subsidiaries and group companies connected to the State Transmission Utility (STU) network to use its GNA without independently applying for their own GNA. The commission held that Regulation 23.1 of the GNA Regulations only allows GNA sharing between two existing GNA grantees and does not extend to non-GNA entities connected to the STU. CERC stated that this was a sectoral issue requiring wider stakeholder consultation and declined to grant an exception through regulatory relaxation.
