India’s renewable energy landscape is evolving rapidly, with an expanding regulatory framework that supports captive generation and green energy open access. These regulations aim to foster self-generation, promote renewable energy usage, and reduce reliance on the grid for Commercial & Industrial (C&I) consumers. As India progresses toward its renewable energy targets and sustainability goals, various national and state-level regulations are paving the way for greater adoption of renewable energy sources such as solar, wind, and hybrid systems.
National Regulations on Green Energy Open Access
India’s national regulations, formulated by the Ministry of Power (MoP), Ministry of New and Renewable Energy (MNRE), and the Central Electricity Regulatory Commission (CERC), provide a comprehensive legal structure for enabling renewable energy adoption. Key regulations and their commencement dates are summarized below:
Regulation | Date of Commencement | Key Highlights |
Electricity (Promoting Renewable Energy Through Green Energy Open Access) Rules, 2022 | June 6, 2022 | - Open access eligibility reduced from 1 MW to 100 kW- No capacity limit for captive consumers- Focus on enabling renewable energy access for small and medium industries |
Electricity (Third Amendment) Rules, 2023 | September 5, 2023 | - Clarified criteria for captive generation plants- Central Electricity Authority (CEA) to verify captive status for multi-state operations |
Electricity (Amendment) Rules, 2024 | January 15, 2024 | - Exemption for specified consumers from transmission license requirements- Rationalization of open access charges |
These national-level rules are designed to simplify access to renewable energy for both captive power producers (CPPs) and independent power producers (IPPs), facilitating the transition toward a greener energy grid and reducing financial barriers to entry for smaller power users.
State Regulations on Green Energy Open Access
At the state level, various State Electricity Regulatory Commissions (SERCs) have developed their own regulations, aligning with national goals while addressing local energy needs. Several states have proactively amended their regulations to encourage the development of renewable energy and facilitate green energy open access.

Major Benefits for Captive Users in India
The Green Energy Open Access framework offers substantial advantages to Commercial & Industrial (C&I) users looking to integrate renewable energy into their operations. These benefits include cost savings, enhanced energy security, and alignment with sustainability goals.
1. Reduction in Energy Costs
Lower Tariffs: Renewable energy tariffs, particularly for solar, have declined significantly, making it an increasingly cost-effective option compared to traditional grid power. In some cases, solar energy is cheaper than power from thermal plants due to reduced operational costs.
Avoidance of Cross-Subsidy Charges: Captive users generating their own renewable energy can avoid or reduce cross-subsidy surcharges, a significant financial burden on grid power users.
Long-Term Price Stability: Long-term power purchase agreements (PPAs) with fixed tariffs can provide price stability, insulating users from future power price volatility.
2. Self-Reliance and Reduced Grid Dependency
Energy Security: Captive renewable energy systems enable users to generate their own power, reducing dependence on the grid, particularly during peak hours or periods of power shortages.
Backup Supply: Solar energy systems can be integrated with battery storage solutions to ensure uninterrupted power supply even during non-sunlight hours, enhancing grid resilience.
3. Environmental and CSR Benefits
Carbon Footprint Reduction: By adopting renewable energy sources, industries can significantly lower their carbon emissions, supporting India's decarbonization objectives and meeting corporate social responsibility (CSR) commitments.
Green Certifications: Renewable energy adoption can contribute to obtaining environmental certifications, enhancing the market reputation of C&I users.
4. Renewable Energy Certificates (RECs)
Tradable Certificates: Captive renewable energy users can earn RECs, which can be traded or used to meet Renewable Purchase Obligations (RPOs), helping to further reduce regulatory costs and align with national renewable energy targets.
5. Reduced Transmission & Distribution (T&D) Losses
Direct Generation: By generating power on-site, captive users eliminate the need for extensive transmission infrastructure, thereby avoiding transmission and distribution losses typically associated with long-distance power delivery.
6. Government Incentives and Subsidies
Financial Support: Both central and state governments offer various financial incentives, including capital subsidies, tax rebates, and accelerated depreciation benefits for renewable energy installations, further enhancing the financial viability of renewable energy projects.
To access green energy through open access, captive users need to comply with specific guidelines and regulations. These include:
Eligibility for Open Access: Most states require a minimum demand of 1 MW or more for CPPs to access open access, though recent amendments in regulations have lowered the threshold to 100 kW in certain states.
Wheeling and Banking Charges: States have defined specific charges for wheeling and banking renewable power, which allows users to store excess energy generated during low-demand periods and retrieve it when needed.
Net Metering and Virtual Net Metering: Net metering allows C&I users to sell excess solar power to the grid, while virtual net metering, available in certain states, allows the sharing of solar power generated at one site with multiple locations.
Conclusion
The evolving Green Energy Open Access regulations in India provide a robust framework for the adoption of renewable energy by C&I consumers. With clear incentives, reduced regulatory barriers, and a growing focus on sustainability, these regulations support the transition toward a greener energy future. As India continues to make strides in its renewable energy goals, the regulatory environment will likely evolve to further simplify the process for C&I users to access and benefit from renewable energy, aligning with national objectives to reduce emissions, enhance energy security, and boost economic growth through green investments.
