The Western Regional Power Committee has reviewed several pending telecom and control-system issues, including RTU availability below 90% at 23 sites, limited UNMS status coverage, SCADA/SEM mismatches, storage-SCADA separation and ongoing telecom follow-up actions. The agenda also references the Rs 411.352 crore, 6,776.1 km OPGW programme supporting regional communications infrastructure. While these items highlight implementation and monitoring challenges, the committee papers do not conclude that they caused any grid disturbance or system outage.

The review underlines the importance of reliable telemetry, communications and operational data as renewable integration and digital grid management continue to expand.

The Western Regional Power Committee has reviewed high-voltage conditions on 400 kV SSP transmission lines, where RBPH units are being operated as synchronous condensers, each absorbing around 35-40 MVAr of reactive power instead of generating their full active output. Agenda papers also record the continued unavailability of Dhule CSR-I and CSR-II reactive support assets, alongside interim measures such as the Balsane LILO and Asoj bypass. The documents describe ongoing operational management rather than a concluded technical finding or permanent solution.

The review illustrates the importance of adequate reactive power resources in maintaining transmission system performance as grid conditions evolve.

The Northern Region Renewable Energy Subcommittee has reviewed 44 renewable plants totaling 12,491 MW for compliance with reactive power requirements. Agenda papers show only seven plants (2,300 MW) as fully compliant, while 31 plants (8,491 MW) remain non-compliant. A further 13 plants totaling 3,840 MW are listed at the SVG financial-technical closure stage, reflecting ongoing corrective work rather than completed compliance. The committee discusses these findings alongside renewable scheduling, fault ride-through capability and broader grid control issues without attributing any specific disturbance to the listed plants.

The review underscores the need for stronger reactive power capability as renewable penetration continues to increase.

The Northern Regional Renewable Energy Subcommittee is reviewing two separate renewable system disturbances alongside battery energy storage protection settings. Agenda papers record events involving approximately 1,100 MW at Bhadla and 2,300 MW at Bawana-Bahadurgarh, while also examining an automatic BESS disconnection setting of 49.6 Hz with a 50-millisecond delay covering 843.1 MW of listed battery storage. The documents additionally record significant renewable schedule deviations but do not conclude that battery storage caused either disturbance.

The review reflects the growing need to evaluate renewable integration, storage controls and system response together as India's power system evolves.

The Western Regional Power Committee revised its DSM statement for 6-12 July after Goa Load Despatch Centre identified missing schedules for five renewable generators caused by a synchronisation issue between the REMC and WBES scheduling systems. Following the correction, Goa's net deviation charge fell by Rs 1.74 crore, while MSEB's increased by Rs 1.55 crore. The updated settlement covered 129 entities, demonstrating how scheduling database accuracy directly affects commercial settlements across the regional power market.

The incident highlights the critical role of dependable scheduling platforms in maintaining transparent electricity market operations.

The NRPC Protection Sub-Committee is set to examine the 18 June Rihand blackout after agenda documents showed the Special Protection Scheme (SPS) delivered only 530 MW of relief during the outage, despite the complete loss of the 2,300 MW generating station. A subsequent event on 17 July also recorded limited SPS performance, with only three of nine substations confirming operation. The agenda additionally points to delayed corrective actions, including pending protection upgrades and the long-overdue regional protection audit programme.

The review highlights the importance of reliable protection systems as India's transmission network becomes increasingly complex.

Grid-India's June ancillary services report shows that 210,471.80 MWh of support from gas-based power stations attracted Rs 468.74 crore in compensation, averaging about Rs 22.3 per unit across eight generating stations. At the same time, the report records renewable curtailment reaching 19,281 MW without compensation under the current regulatory framework. It also notes that the tertiary reserve up-regulation market cleared zero energy during June, meaning upward reserve support came entirely through the compensation mechanism rather than market clearing.

The findings highlight the growing importance of balancing dispatchable generation with renewable integration as grid operations become more complex.

Greenko's Pinnapuram Pumped Storage Project recorded three major trips within 48 hours, including a complete 1,200 MW outage during the evening peak on 25 July and two further disturbances on 26 July linked to 400 kV bus-bar protection. Although most generating units were restored quickly after each event, Unit 1 remained unavailable at the reporting cut. The plant continued supporting grid balancing through pumping and generation, but repeated switchyard interruptions highlight the importance of reliable transmission infrastructure for large-scale energy storage assets.

The incident demonstrates how grid-side equipment can directly influence the performance of pumped storage projects supporting renewable integration.
