Green Energy Open Access Rules: A Brief Overview

The Green Energy Open Access rules are pivotal in ensuring that consumers have the opportunity to choose clean energy sources for their power needs. These rules empower consumers to access green energy, such as solar and wind power, by amending relevant regulations and ensuring consistency with the overarching principles of open access.

Key highlights of the Green Energy Open Access Rules include:

  • Swift Approval Process: The nodal agency responsible for managing open access applications is required to approve these requests within a short time frame of fifteen days. This speedy approval process ensures that consumers can swiftly transition to green energy sources without unnecessary delays.
  • Eligibility Criteria: To qualify for Green Energy Open Access, consumers must have a contracted demand or sanctioned load of a hundred kW and above. This threshold ensures that those with substantial power requirements can take advantage of green energy options.
  • No Supply Limit for Captive Consumers: Captive consumers, those who generate and consume their power, face no limitations on the supply of power when utilizing Green Energy Open Access. This encourages self-sufficiency and reduces the burden on traditional power grids.
  • Balancing High Variations in Demand: To maintain grid stability and avoid sudden fluctuations in demand, reasonable conditions, such as limiting the number of time blocks for changing power consumption, may be imposed. These conditions help ensure a smooth transition to green energy sources without disrupting the power supply.

  • Revamped “Entity” Definition: Previously, an “entity” was any consumer with a contracted demand or sanctioned load of 100 kW or more, except for captive consumers who had no load limit. Now, the definition expands to include those with 100 kW or more, achieved through either single or multiple connections in the same electricity division of a distribution licensee.
  • Unlimited Access to Green Energy: First Proviso, has been updated to grant all entities, whether through a single connection or multiple connections totalling 100 kW or more within the same electricity division, the eligibility to access Green Energy Open Access. Captive consumers, in particular, now enjoy unrestricted access to this green energy resource.
  • Extended Surcharge Exemption: Rule 9 now extends surcharge exemption for electricity generated from offshore wind projects. The new deadline for commissioning such projects is December 2032, offering an extended window of opportunity compared to the previous deadline of December 2025.

Open Access Charges

  • Distribution (Wheeling) Charges: are also known as wheeling charges, are the costs incurred when transporting solar power from one location to another through the local distribution network. Think of it as the fee for using their infrastructure. These charges vary by region and can significantly impact your solar project’s economics.
  • Transmission Charges: Transmission charges come into play when solar energy must traverse long distances through high-voltage lines to reach a distant consumer or location. The costs depend on the amount of power and the distance it travels. If your solar project involves supplying power to a remote location, these charges deserve attention in your financial calculations.
  • Cross Subsidy Surcharge: is a fee aimed at compensating distribution companies for revenue losses due to large consumers migrating to open access. It helps maintain the financial health of local distribution providers. These surcharges can differ between states and distribution companies, so be sure to account for them.
  • Additional Surcharge: is a regulatory fee covering extra costs incurred by distribution companies due to open access arrangements. These costs can include infrastructure upgrades and administrative expenses. The specific charges depend on your solar project’s size and capacity, so consult with local utility and regulatory bodies for clarity.
  • Banking Charges*: are also called energy banking charges, pertaining to storing excess solar energy generated during sunny periods for later use. These charges may apply when you feed surplus energy into the grid and withdraw it during low-production periods. Understanding banking charges helps optimize your solar project’s financial benefits, particularly if you’re considering energy storage solutions.

Type of Open Access Consumers

Open access activity can be categorised based on three primary parameters:Types of Green Energy Open-Access Consumers

  1. (LTOA, MTOA, or STOA) based on Duration of Access :
  • Long-Term Open Access (LTOA): Consumers with long-term energy requirements opt for LTOA. This provides them with a stable and reliable source of energy over an extended period.
  • Medium-Term Open Access (MTOA): MTOA consumers have slightly more flexibility in their energy procurement, catering to mid-term needs.
  • Short-Term Open Access (STOA): STOA consumers, on the other hand, require energy for shorter durations, often to meet peak demand or seasonal variations.
  1. Captive or Non-Captive:
  • Captive Consumers: These consumers generate their own power for self-consumption. They may utilize solar panels or other renewable sources to meet their energy needs independently.
  • Non-Captive Consumers: Non-captive consumers rely on external sources for their energy requirements, making them the primary users of open access systems.
  1. Renewable or Conventional Power:
  • Renewable Power: As the world moves towards a sustainable future, an increasing number of consumers are choosing renewable energy sources like solar power. These consumers contribute to a cleaner and greener environment.
  • Conventional Power: Some consumers may still rely on conventional sources like fossil fuels or grid electricity for their energy needs.

Open Access Application Process

Open access application process

  • Nodal Agency: In most States, STUs (State Transmission Utilities) handle LTOA (Long-Term Open Access) and MTOA (Medium-Term Open Access), while SLDCs (State Load Dispatch Centers) manage STOA (Short-Term Open Access). Maharashtra and Chhattisgarh have their State Discoms as the nodal agencies. Even when SLDCs oversee the process, they operate as part of the STU.
  • Required Documents: Acquiring an NOC (No Objection Certificate) from State utilities is the main challenge in securing open access approvals. In Chhattisgarh, Gujarat, Tamil Nadu, and Jharkhand, you need an NOC along with your open-access application, potentially causing delays and complications before submission. Moreover, the criteria for granting NOCs can be subjective and hard to verify for consumers.
  • Application Processing Time: The processing time for open-access applications varies significantly from state to state. In Andhra Pradesh, LTOA applications are deemed approved within 30 days.
  • Application Cost: The application fee structure for open-access applications differs based on the state, application period, load, connection point, and power source. Although the application fee varies widely across states, the cost per unit is generally minimal.
