The government is advancing a comprehensive digital and infrastructure transformation of India’s power sector through the development of the India Energy Stack and large scale integration of renewable energy into the national grid, Minister of State in the Ministry of Power Shripad Naik informed in a written reply in the Rajya Sabha.
The India Energy Stack is being developed as a digital blueprint for the country’s power sector to enable seamless communication, data exchange and coordination across the electricity value chain. The initiative aims to connect different components of the power system through secure digital protocols and interoperable platforms so that utilities, regulators and service providers can exchange information and operate efficiently.
The Ministry of Power has constituted a task force comprising domain experts and representatives from key stakeholders including central ministries, state utilities, regulators, generating companies and transmission companies to prepare a roadmap for the development and implementation of the India Energy Stack. The framework is designed to establish standard protocols and specifications that ensure interoperability across systems, enabling data, services and infrastructure within the power sector to function together seamlessly.
Pilot implementation of the India Energy Stack will be undertaken in select power distribution utilities located in Delhi, Gujarat, Andhra Pradesh, Uttar Pradesh and Mumbai. These pilot projects are expected to demonstrate the operational capabilities of the system during the financial year 2026 to 2027.
A total allocation of 51.3 crore rupees has been made for the development of the India Energy Stack, of which 3.88 crore rupees has been released so far for initial work related to design and implementation.
Alongside the digital transformation of the power sector, the government is accelerating the integration of renewable energy into the national grid through large scale transmission infrastructure expansion and energy storage deployment.
To support the country’s clean energy transition, the government has planned major upgrades to the transmission network under the National Electricity Plan. The plan projects the expansion of the transmission network of 220 kilovolt and above lines to approximately 6.48 lakh circuit kilometres by the year 2031 to 2032. Transformation capacity is also expected to increase to around 2,345 gigavolt ampere during the same period.
Inter regional transmission capacity is projected to increase significantly from 120 gigawatt in January 2026 to 168 gigawatt by 2032. These improvements will strengthen the national grid and enable efficient transfer of renewable energy generated in different regions of the country.
The expansion of the transmission network is aligned with the national target of integrating more than 500 gigawatt of non fossil fuel electricity capacity by 2030 and over 600 gigawatt by 2032. Transmission schemes associated with renewable energy generation projects are currently being implemented in phases to match the pace of renewable capacity additions.
The Ministry of New and Renewable Energy is implementing the Green Energy Corridor programme to facilitate evacuation and integration of renewable power. The programme is being executed as intra state transmission projects across ten states including Rajasthan, Karnataka, Andhra Pradesh, Himachal Pradesh, Madhya Pradesh, Kerala, Gujarat, Uttar Pradesh, Maharashtra and Tamil Nadu.
The Green Energy Corridor programme is being implemented in two phases, Green Energy Corridor One and Green Energy Corridor Two, with the objective of enabling the evacuation of around 44 gigawatt of renewable energy capacity. Out of this, about 26 gigawatt of renewable energy has already been integrated into the grid. A third phase of the programme aimed at supporting large scale renewable energy integration is currently under consideration.
To address the variability and intermittency associated with renewable energy sources such as solar and wind, the government is promoting the use of energy storage technologies and hybrid power generation solutions. Pumped Storage Projects and Battery Energy Storage Systems are being developed to maintain grid stability and ensure reliable electricity supply.
Under the National Electricity Plan, transmission systems have already been planned to support approximately 35.6 gigawatt of pumped storage projects by 2031 to 2032. In addition, transmission infrastructure is being prepared to support the development of around 100 gigawatt of pumped storage capacity between the years 2025 to 2026 and 2035 to 2036.
Battery Energy Storage Systems are also being integrated into the power system to support renewable energy expansion. The government has considered the deployment of around 47 gigawatt of battery energy storage capacity by 2031 to 2032. To support these systems, two viability gap funding schemes have been introduced to facilitate the development of approximately 43.8 gigawatt hour of battery storage capacity.
The Ministry of Heavy Industries is also implementing the National Programme on Advanced Chemistry Cell Battery Storage with a production linked incentive scheme valued at 18,100 crore rupees. The programme aims to establish 50 gigawatt hour of advanced battery manufacturing capacity in the country, including 10 gigawatt hour dedicated to grid scale storage.
Regulatory reforms are also being introduced to support renewable integration. The Central Electricity Regulatory Commission has introduced solar hour and non solar hour connectivity provisions under the Connectivity and General Network Access to the Inter State Transmission System Third Amendment Regulations 2025. These provisions allow better utilisation of transmission infrastructure and encourage hybrid renewable projects combining solar, wind and battery storage systems.
The government is also expanding rooftop solar adoption across the country through the PM Surya Ghar Muft Bijli Yojana launched in February 2024. The programme aims to install rooftop solar systems in one crore residential households by the financial year 2026 to 2027 with a total outlay of 75,021 crore rupees.
The scheme has simplified procedures for rooftop solar adoption by introducing a fully online application and subsidy disbursement system through the national portal. Subsidies are transferred directly to the bank accounts of residential consumers. The programme also provides collateral free loans from nationalised banks at concessional interest rates with a tenure of ten years, with loan applications available through the JanSamarth portal.
Further regulatory simplifications include waiving the requirement for technical feasibility approval and enabling automatic load enhancement up to 10 kilowatt to make rooftop solar adoption easier for households.
As of February 2026, around 31.04 lakh households have installed rooftop solar systems under the scheme.
India’s renewable energy capacity has already reached around 263 gigawatt as of January 2026. Transmission infrastructure under the Inter State Transmission System is currently being developed to support the integration of approximately 207 gigawatt of upcoming wind and solar power capacity. In addition, around 18 gigawatt of renewable energy capacity is being integrated through intra state transmission networks under the Green Energy Corridor programme.
The government has also planned an additional hydroelectric capacity of around 19 gigawatt by the year 2030 to support clean energy expansion.
These initiatives together aim to strengthen the national grid, enhance grid flexibility and ensure reliable and affordable green power supply while supporting India’s transition toward a low carbon energy system.
