India is moving to keep rooftop solar telemetry on India-based servers to protect data leakage, as the Ministry of New and Renewable Energy advances a national, vendor-neutral data layer for inverters under the PM Surya Ghar program, which targets 10 million homes and 30 GW of capacity. The draft framework standardizes how inverter-side devices authenticate and publish data to a centralized platform, aiming to mitigate cyber risk and enhance grid visibility. The push is framed around energy sovereignty, amid concerns that some monitoring dongles and loggers have been routing data to overseas servers.

The Ministry of New and Renewable Energy took serious note of government agencies issuing tenders in August this year with short bid submission timelines, clearly intended to circumvent the Approved List of Models and Manufacturers mandate on solar cells. It stated that any existing tenders with short bidding timelines that have been issued without complying with the General Financial Rules and Central Vigilance Commission regulations must be scrapped, if necessary, and new bids issued in full compliance with the rules. “Action taken in this regard may be reported back positively within 15 days,” MNRE said in a communication to renewable energy bidding agencies of the Union and state governments.

The Central Electricity Regulatory Commission notified the Connectivity and General Network Access to the Interstate Transmission System (Third Amendment) Regulations, 2025. The new rules modify several aspects of the Principal Regulations of 2022, introducing expanded definitions, revised procedures for application withdrawals, restructuring of bank guarantee requirements, rules for connectivity to interstate transmission system substations, and detailed compliance obligations for renewable generating stations and energy storage systems.

The Central Electricity Regulatory Commission admitted petitions from solar developers seeking compensation for power generation losses and financial losses resulting from power curtailment due to inadequate transmission systems. They have sought directions to Power Grid Corporation of India and the Central Transmission Utility of India to provide them the compensation until the operationalization of the associated transmission system. The petitioners are ACME Solar Holdings and AMPIN Energy Green. The Commission clubbed their petitions with similar ones filed by Juniper Green Cosmic and NTPC Green Energy.

The Ministry of Power wrote to all states and union territories, urging them to scrap separate net-metering contracts for residential rooftop consumers and adopt a digital agreement as part of the online application. It cited sub-rule 10 of rule 4 of the Electricity (Rights of Consumers) Rules, 2020, which provides that if an agreement is required between a distribution licensee and a consumer, it should become part of the application form and not require a separate net-metering agreement. The ministry noted that Gujarat, Rajasthan, Karnataka, Jharkhand, Haryana, and Puducherry already use a digital form for the net-metering agreement, which is part of the online application in the national portal for rooftop solar.
