Wiring power grid data: How India Energy Stack is moving from blueprint to build

The India Energy Stack taskforce's final report is in and procurement underway. The harder task is persuading state-regulated utilities to adopt the common standardsIndia’s efforts to create a common digital backbone for its electricity sector entered a new phase on October 29 when the taskforce overseeing the India Energy Stack (IES), a government-led Digital Public Infrastructure (DPI) for the power ecosystem, reviewed its final report in New Delhi and laid out a pathway for national implementation.The next milestone is already on the calendar. A tender published on October 26 seeks a software development agency to design, build and support the platform over 730 days, with bids due on November 7. The move shifts the initiative from designing common standards towards building the systems needed to put them into practice.Yet the timetable has already stretched: REC Limited, the nodal agency, had earlier said the project was scheduled for completion by July 2026. A national rollout is still ahead, and its success will depend on whether India’s diverse power utilities adopt the framework.The ambition is to do for electricity what the Unified Payments Interface (UPI) did for digital payments. When the taskforce was announced in June 2025, Union power minister Manohar Lal Khattar said the stack would do for the power sector “what Aadhaar did for identity and UPI achieved for digital payments”. In practice, that means allowing different institutions to transact and exchange information through common digital rails, without requiring each participant to build a separate connection with every other. Yet electricity is a more complex proposition. Payments move through digital networks; electricity must be balanced across a physical grid in real time, with scheduling, billing, regulation and reliability all dependent on accurate information.The IES is part of a wider government effort to extend DPI beyond identity, payments and welfare delivery into the productive economy. Its scale is already visible across sectors, although the initiatives are at different stages of maturity. AgriStack, a DPI to create a unified digital ecosystem for the agriculture sector, had generated more than 103.1 million Farmer IDs by August 2026.By mid-August, the Ayushman Bharat Digital Mission had created more than 960 million health accounts and linked over 1,100 million health records. The Open Network for Digital Commerce crossed 500 million cumulative transactions in July. The National Digital Tourism Stack, launched on September 27, has set a target of bringing 23,000 tourism experiences and homestays onto its network by the end of 2028.NITI Aayog’s DPI@2047 roadmap, unveiled in April, identifies eight sectoral transformations, spanning MSMEs, agriculture, education and health, along with credit, benefit delivery and decentralised energy markets. Energy is not first in line, however. The roadmap’s first two-year cycle, for 2026-27, focuses on MSMEs and agriculture.The common idea is to move beyond digitising individual services and create shared infrastructure through which institutions can exchange data, expand access and enable new services. In electricity, a sector whose physical infrastructure has grown in scale and complexity while its digital systems often remain fragmented, that could address a longstanding problem.The IES taskforce, constituted by the ministry of power in June 2025, is chaired by Ram Sewak Sharma, a former director general of the Unique Identification Authority of India and former chief executive of the National Health Authority, which runs the health mission cited above. Pramod Varma, Aadhaar’s former chief architect, is the taskforce’s chief architect. Pradeep Kumar Pujari, a former power secretary and former chairman of the Central Electricity Regulatory Commission, is vice-chair. Infosys co-founder Nandan Nilekani is chief mentor. REC Limited is the nodal agency and FSR Global the knowledge partner.The taskforce has developed the IES around a straightforward principle: common standards should allow organisations to exchange information while retaining their existing software and systems. The framework is built around three functions: register, discover and exchange. Participants register through verifiable digital identities; other participants can discover and verify them and the services available. Information is then exchanged through common data formats and protocols.The IES is not intended to replace utility systems with a single national database. It seeks to make those systems interoperable. That could reduce the need for bespoke software connections, lower integration costs and make it easier for new service providers to work across state boundaries. The government has described the initiative as a way to enable standardised data exchange, real-time analytics and improved consumer services across the power-sector value chain. The idea also has a precedent: Uttar Pradesh piloted the Unified Energy Interface, an open protocol for energy transactions, in Lucknow in 2020-21 for electricity billing and meter data exchange.The first tests have involved six utilities across five states: Tata Power Mumbai, Andhra Pradesh Eastern Power Distribution Company Limited, Dakshin Gujarat Vij Company Limited, Paschimanchal Vidyut Vitran Nigam Limited, BSES Rajdhani Power Limited and Tata Power Delhi Distribution Limited. The pilot list includes both public and private distribution companies, offering an initial test of whether common protocols can work across different operating environments. Yet six participants remain a small sample for a sector spread across states, with different regulatory practices, legacy systems and levels of digital readiness.The seven priority use cases for the next phase are largely administrative, but potentially consequential. They include submitting generator schedules to state load despatch centres, enabling single-window scheduling for bilateral transactions, issuing verifiable no-objection certificates for open access, and standardising the aggregate revenue requirement filings that distribution companies make to state electricity regulatory commissions. The others are data exchange within distribution companies’ own systems, verification of generator bills and converting Central Electricity Authority reporting formats into machine-readable schemas.These processes involve repeated exchanges of operational and commercial information. Standardisation could reduce manual reconciliation, improve audit trails and shorten the time taken to verify submissions. For regulators, common data formats may make tariff filings easier to compare across utilities. For generators and other market participants, they could reduce the effort required to comply with different administrative systems.The consumer-facing work is also beginning to take shape. Through a partnership with the National e-Governance Division, consumers can access a Consumer Energy Passport and Consumer Meter Digest through DigiLocker. Peer-to-peer (P2P) energy trading has gone furthest. REC invited technology providers in January to build an inter-state P2P trading pilot on IES specifications, and in February it ran a live demonstration at the India AI Impact Summit in New Delhi, in which a farmer in Meerut sold six units of rooftop solar power to a shop owner in Delhi for Rs 30.REC called it the most visible application of the stack so far. These are early applications, not evidence that a nationwide energy marketplace is already operational. Their wider use will depend on utility participation, regulatory approvals, commercial rules and consumer demand.Overall, the timing of the effort is significant. India’s electricity system must accommodate changing patterns of generation and consumption, including the growth of renewable energy and distributed resources such as rooftop solar. That increases the importance of reliable information moving between grid operators, generators, distribution companies and consumers.Much of that information will come from smart meters, whose rollout remains uneven: about 61.3 million had been installed nationally by July 2026 against the roughly 230 million sanctioned under the Revamped Distribution Sector Scheme (RDSS) and earlier programmes. A common digital layer could help coordinate these interactions, although it cannot replace investment in the physical grid or resolve the financial weaknesses of distribution companies.The biggest hurdle may be institutional rather than technical. Distribution companies differ sharply in their finances, software, staffing and capacity to undertake upgrades. Adopting common standards can require changes to procurement contracts, internal workflows and data-management practices.Capacity is thin: the government has allocated Rs 100.9 crore under RDSS to train distribution company staff, and 14,853 people had been trained by July 2026—a modest number for a workforce of this size. Utilities will also need clarity on who bears the cost, who is responsible when data is incorrect, and how information will be protected from unauthorised access.A central question remains: what will make utilities join? The taskforce has recommended that power-sector stakeholders prepare to adopt the IES. The strategy document published in March sets out a staged pathway, from building and validating use cases through calibrated deployment to scale, with gate criteria before each use case advances.But public accounts of the final report do not say whether adoption will be made mandatory through ministry of power rules or regulatory orders, encouraged through funding conditions such as those under RDSS, or left to each utility’s discretion. UPI gained scale partly because the Reserve Bank of India and the National Payments Corporation of India could set the rules for banks. Electricity distribution is regulated state by state, so no single body can do the same.Cybersecurity, data quality and privacy will be central to that effort. A common framework can make data exchange more consistent, but it cannot guarantee that the underlying information is accurate. Nor does interoperability eliminate the risk of cyberattacks. The compliance burden on utilities is also rising. The Central Electricity Authority notified the Cyber Security in Power Sector Regulations on July 31, the sector’s first legally binding cybersecurity framework, covering audits, incident reporting and supply-chain security, with most provisions in force from April 1, 2027.At the distribution utility meet, organised by the India Smart Grid Forum in Jaipur on October 27-28, a full session was given to the IES, data exchange, cybersecurity and data privacy, and the agenda listed distribution companies’ readiness for both the IES and the new cybersecurity regulations. Consent-based sharing of consumer data will also have to comply with the Digital Personal Data Protection Act. Under the rules notified in November 2025, provisions on registered consent managers take effect in November 2026, and core obligations on notice, consent and security safeguards apply from May 2027, roughly when the IES platform will be under construction.The taskforce has recommended an institutional mechanism to maintain the specifications and establish conformance certification. That will be critical as the network expands. Standards must evolve with technology and regulation, without forcing every utility to upgrade at the same pace. Certification will need to be transparent, while procedures for resolving technical disputes and maintaining compatibility must be clearly defined. The specifications and schemas have been published openly, with a contribution portal on REC’s website inviting stakeholders to propose additions. The challenge is to turn an open technical framework into a system that institutions trust and consistently use.The next step is procurement. REC’s tender, published on October 26, seeks an agency to design, develop and implement the IES, with production support and maintenance over 730 days. Bids close on November 7 and are scheduled to open the following day. The timeline offers a concrete marker of progress, but the tender itself does not establish the cost of a nationwide rollout or guarantee adoption by utilities.The initiative should therefore be assessed against measurable outcomes: how much time is saved in scheduling and billing, whether manual errors and reconciliation costs fall, how quickly regulatory filings are processed, and how many utilities actively exchange data through the framework. It will also be important to track whether smaller utilities can join without disproportionate expense. In March 2026, the government told the Rajya Sabha that Rs 51.3 crore had been allocated for the initiative, of which Rs 3.88 crore had been released. Those figures are an early funding snapshot, not a final estimate of implementation costs.UPI provides a useful analogy, but not a ready-made blueprint. Its success rested on common protocols, broad participation and a clear everyday use case. Electricity has a more demanding operating environment, with physical constraints and regulatory responsibilities that cannot be standardised away. The Energy Stack can improve the information flows underpinning the system; it cannot substitute for better utility finances, sound regulation or grid reliability.India has shown that shared digital infrastructure can operate at considerable scale. The India Energy Stack now has a proposed architecture, a set of pilots, published specifications and a procurement process for the next phase. The real test begins when utilities must adapt their systems and make common standards part of routine operations. Its success will be measured not by the launch of another digital platform, but by whether it makes India’s electricity system easier to coordinate, regulate and use.Subscribe to India Today Magazine- Ends
