Introduction:
Rajasthan, often called the “Land of Kings,” is not only rich in culture and history but also blessed with abundant sunshine, making it a prime location for solar energy. To further accelerate the adoption of clean energy and empower businesses and industries to embrace sustainable practices, the Rajasthan Electricity Regulatory Commission (RERC) has introduced the RERC Green Open Access Regulations, 2025. These new rules are designed to make it easier for consumers to access and utilize green energy, bringing a fresh wave of opportunities for solar open access 2025.
This detailed guide will break down the crucial aspects of these regulations in simple language, explaining who can benefit, what the new rules on banking and charges mean, and how Novergy, a leading solar energy provider in India, can help you navigate this exciting green energy journey in Rajasthan.
What is Green Energy Open Access? A Simple Explanation
Imagine you want to buy vegetables directly from a farmer instead of only from the local market. Green Energy Open Access is similar. It allows you to directly buy green or renewable energy from a power generator, bypassing the traditional distribution company (DISCOM) for all or part of your electricity needs. This is particularly beneficial for businesses that want to reduce their carbon footprint, achieve sustainability goals, and potentially save on electricity costs.
The RERC Green Open Access Regulations, 2025 are a significant step by the Rajasthan government to promote the use of clean energy sources like solar and wind power. They aim to make this “direct buying” process smoother and more attractive for solar open access 2025.
Who Can Apply for Green Energy Open Access in Rajasthan?
The new regulations clearly define who can take advantage of Green Energy Open Access in Rajasthan:
- Consumers with Higher Demand: If your business or establishment has a contract demand or sanctioned load of 100 kW (kilowatts) or more, you are generally eligible. This can be from a single electricity connection or from multiple connections located in the same area, adding up to 100 kW or more. This means medium to large commercial and industrial consumers are the primary beneficiaries of these rules, making solar open access 2025 a viable option for many in Rajasthan.
- No Lower Limit for Captive Use: This is a fantastic provision for those who have their own power plant (a “captive generating plant”) and primarily use the energy for their own needs. For captive consumers, there’s no lower limit on the amount of electricity you need to use to qualify for green energy open access. This greatly supports self-sufficiency in renewable energy within Rajasthan.
- Maximum Capacity for Captive Plants: The regulations allow new renewable energy captive power plants to be quite large – up to 200% of your contract demand. This means if you’ve agreed to buy a certain amount of electricity from the regular grid, you can now generate up to twice that amount yourself using your captive solar energy plant or other renewable energy sources. This provides significant flexibility for businesses looking to expand their green energy generation in Rajasthan.
The Role of Battery Energy Storage Systems (BESS) in 2025
With the increasing use of solar energy and wind power, which are dependent on weather conditions, storing energy has become crucial for a stable electricity supply. The RERC Green Open Access Regulations, 2025 emphasize the importance of Battery Energy Storage Systems (BESS) for certain projects in Rajasthan:
- BESS for Larger Captive Plants: If your renewable energy captive plant generates between 100% and 200% of your contract demand, you’ll need to install a BESS. This battery system must be able to store at least 20% of the additional energy generated beyond your 100% contract demand. This helps ensure that the excess power you generate during sunny or windy periods can be used when your generation is low, supporting solar open access 2025.
- BESS for STU Network Projects: New renewable energy projects connected to the State Transmission Utility (STU) network with an installed capacity over 5 MW (megawatts), excluding large hydro projects, must also install a BESS. This BESS needs to store at least 5% of their renewable energy capacity for a minimum of 2 hours. This provision is vital for maintaining grid stability as more green energy comes online in Rajasthan.
Transmission and Wheeling Charge Exemptions for BESS:
To encourage the adoption of storage solutions, the regulations offer attractive exemptions on charges for using the electricity transmission and distribution networks in Rajasthan:
- For RE Integrated Storage Projects: If your Battery Energy Storage System is part of your renewable energy project and stores up to 5% of your renewable energy capacity, you get a significant 75% exemption on transmission and wheeling charges for 7 years.
- Increased Exemptions with More Storage: The benefits get even better! This exemption increases as you add more storage, going up to a full 100% exemption for BESS that stores more than 30% of your renewable energy capacity. This clearly shows the emphasis on robust storage solutions for solar open access 2025.
- Standalone BESS Benefits: If you have a BESS that operates independently (not directly integrated with a renewable energy plant) and supplies power during peak or non-solar hours, it also receives a 100% exemption on transmission and wheeling charges for 7 years. This is a great incentive for energy storage providers in Rajasthan.
- BESS at Lower Voltage Substations: Battery systems connected to certain lower voltage grid substations (11 kV or 33 kV) also receive a 100% exemption. These exemptions significantly reduce the cost of integrating storage into renewable energy projects, making solar open access 2025 even more appealing in Rajasthan.
Understanding Banking: Saving Your Green Energy
“Banking” is a very important feature of Green Energy Open Access, especially for those generating their own power. It’s like having a savings account for your electricity. Banking is allowed up to 100% of Capacity or 100% to 200% of the Contract Demand.
- What is Banking? If your captive renewable energy plant generates more green energy than you use at a particular time, you can inject that surplus into the grid. The distribution company will then credit this banked energy to your account. You can then draw this “saved” energy later when your consumption is higher than your generation. This helps manage the intermittent nature of solar energy and wind power in Rajasthan.
- Banking Charges: There is a charge for banking your energy, set at 8% of the banked energy. This charge will be deducted “in kind,” meaning 8% of the banked energy units will be reduced from your account before you can withdraw it.
- Lapsing of Unutilized Energy: Any banked energy that you don’t use by the end of the financial year will lapse. However, there’s a silver lining: the plant can receive Renewable Energy Certificates (RECs) for this lapsed energy, which can be traded.
- Agreement Required: To use the banking facility, captive generating stations must enter into a formal Wheeling and Banking Agreement with the Distribution Licensee in Rajasthan.
- Applicability: These banking provisions are applicable to both existing and new renewable energy projects until March 31, 2030, or until a new date is announced by the Commission. This long-term applicability provides certainty for investors and developers in Rajasthan.
- Banking for Green Hydrogen/Ammonia: The rules also mention that banking for renewable energy plants that produce green hydrogen or green ammonia will follow the State Government’s specific policy in this area. This highlights Rajasthan’s commitment to emerging green technologies.
Decoding Transmission, Wheeling, and Other Charges in 2025
When you use the grid to transmit your green energy, various charges apply. The RERC Green Open Access Regulations, 2025 clarify these in Rajasthan:
- Transmission Charges: These are fees for using the large power lines that carry electricity across the state (the transmission system). The Commission will determine these charges separately.
- Wheeling Charges: These are fees for using the local power lines that distribute electricity to homes and businesses (the distribution system). Like transmission charges, these will also be determined by the Commission.
- Additional Surcharge: This charge generally won’t apply if you’re already paying a fixed charge to the distribution company for the amount of green energy you’re taking through open access, up to your contract demand. This avoids double charging.
- It’s also not applicable for captive generation plants, Municipal Solid Waste-to-Energy plants, offshore wind projects commissioned up to December 2032, or if green energy is used for producing green hydrogen/ammonia. These exemptions are designed to further promote specific renewable energy projects in Rajasthan.
- Standby Charges: These are charges for backup power provided by the distribution company. If your green energy source (like your solar energy plant) is temporarily unavailable due to outages, the DISCOM can provide standby power. These charges are 25% of the energy charges for your tariff category, in addition to the actual tariff for the standby energy supplied. However, a helpful provision is that these charges are not applicable if you give at least one day’s advance notice before the Day Ahead Market (DAM) closure time. You also have the flexibility to arrange standby power from another source.
- Reactive Energy Charges: These charges relate to the management of reactive power, which is essential for maintaining voltage stability in the grid. The Commission will determine these charges.
- Energy Losses: You will also be responsible for energy losses that occur in the transmission and distribution system. This is a common practice in electricity supply.
Other Important Points in the RERC Green Open Access Regulations, 2025
Beyond the charges and banking, the regulations cover several other important aspects in Rajasthan:
- Types of Open Access: The regulations categorize open access based on how long you want to use the system:
- Long-term: More than 12 years, up to 25 years. This provides long-term certainty for large-scale projects, including those in solar park areas.
- Medium-term: More than 3 months, up to 3 years.
- Short-term: Up to one month at a time. This offers flexibility for temporary needs.
- Nodal Agency: A central agency will handle all applications for green energy open access, routing them to the State Nodal Agency (SNA). In Rajasthan, the State Transmission Utility (STU) will be the SNA for long and medium-term access, while the State Load Despatch Centre (SLDC) will handle short-term access. This streamlines the application process for solar open access 2025.
- Allotment Priority: The regulations define a clear priority for allotting open access capacity. Distribution licensees have the highest priority. Among Green Energy Open Access (GEOA) consumers, long-term GEOA consumers have preference, followed by medium-term and then short-term. Decisions are generally made on a “first come, first served” basis, ensuring fairness.
- Metering: All green energy open access entities must have meters that meet Central Electricity Authority standards at the generator, interface points (where your plant connects to the grid), and consumption places. These meters will be regularly inspected, tested, and sealed by the Distribution Licensee to ensure accuracy and transparency.
- Application Fees & Payment Security:
- Long-term GEOA: A non-refundable fee of Rs 1,00,000 and a bank guarantee of Rs 10,000/MW of power to be transmitted. You’ll also need to deposit an amount equal to 3 months of transmission charges with STU, 3 months of SLDC fees with SLDC, and 3 months of wheeling charges, cross-subsidy surcharge, and additional surcharge with the Distribution Licensee.
- Medium-term GEOA: A non-refundable fee of Rs 20,000.
- Short-term GEOA: A non-refundable fee of Rs 5,000. All applicable charges (transmission, SLDC, wheeling, surcharges) must be paid in advance. These fees ensure serious applications and provide financial security.
- Green Energy Tariff: Consumers in Rajasthan can choose to purchase green energy for a percentage of their consumption or their entire consumption. The tariff for green energy will be determined separately by the Commission, likely encouraging competitive pricing. Requisitions for green energy from a distribution licensee must be for a minimum of one year, and the quantity must be pre-specified for at least one year.
- Green Certificate: The distribution licensee will issue a green certificate yearly to consumers who purchase green energy beyond their mandatory renewable energy purchase obligation. This certificate serves as recognition of your commitment to green energy.
- Rating: The Commission may introduce a rating system for consumers based on the percentage of green energy they purchase. This could be a way to further encourage and recognize businesses and individuals who actively adopt clean energy.
- Dispute Resolution: The regulations outline a clear process for resolving disputes related to Green Energy Open Access. Disputes will first go to the SLDC, then the State Power Committee, and finally to the Commission, whose decision will be final. This provides a structured mechanism for addressing any issues that may arise.
The Bigger Picture: Rajasthan’s Solar Park Development and Beyond
Rajasthan has been a frontrunner in solar energy development in India, with ambitious plans for establishing large solar park areas. The RERC Green Open Access Regulations, 2025 fit perfectly into this larger vision. By making it easier for industries and businesses to consume green energy through open access, these regulations will further boost the demand for power from these large-scale solar parks and other renewable energy projects across the state. This comprehensive regulatory framework, combined with the state’s natural resources, is paving the way for Rajasthan to solidify its position as a leader in India’s renewable energy sector.
