What is Open Access in Electricity: Complete Guide

Open Access In The Power Sector & Solar Power System And It’s Benefits

Are you interested in knowing about open access electricity & how it benefits industries or large consumers? Open access in the power sector allows large electricity users, typically those with loads above 1 MW, to purchase power directly from the open market instead of relying on their local utility. It not only helps industrial & commercial users lower their energy costs but also supports the growth of a dynamic power market.

A benefit of open access electricity is that it enables consumers to fulfill their Renewable Purchase Obligations (RPOs) by accessing clean energy options. For example, a large user can opt for solar open access by buying green power from rooftop solar installations on-site or from offsite solar farms through open access. But rooftop solar solutions has challenges like higher initial costs and limited scalability. Open access in electricity provides flexible, large-scale renewable energy sourcing that helps to reduce grid pressures. 

Open access in the power sector plays a crucial role in addressing power shortages & stabilizing energy supply. This system encourages competitive pricing, which drives down electricity costs. Open access electricity is transforming how large industrial & commercial consumers produce the power. This shift in the power sector answers critical questions about electricity distribution & sets the stage for a more efficient, cost-effective energy market. This blog will help you understand the key aspects of open access in electricity and its impact on the power sector.

What is Open Access Electricity?

At GSE Renewables, we offer renewable energy solutions to businesses with cleaner & cost-effective energy solutions through open access electricity, a progressive policy under India’s Electricity Act of 2003. These systems allow consumers, typically those with energy needs greater than 1 MW, to purchase electricity directly from the open market instead of relying on local distribution companies. 

Through open access in electricity, businesses can source power from multiple channels like power exchanges, solar parks, independent power producers or even their own captive plants. This shift promotes transparency, reduces dependency on monopolistic utilities & opens up access to more competitive electricity rates.

Open access electricity in India offers benefits to businesses looking to optimize energy costs & reduce their carbon footprint. Companies can meet their Renewable Purchase Obligations (RPOs) to get reliable renewable clean energy. Regulated by the Central Electricity Regulatory Commission (CERC) & State Electricity Regulatory Commissions (SERCs), this system ensures grid stability with consumer flexibility.

Connect with us to unlock the full potential of open access electricity for savings electricity cost, support sustainability & gain energy independence with expert guidance from our team.

on the open market, it will inevitably result in competitive pricing, which will drive down the price of electricity.

In India, the Electricity Act of 2003, which established rules for competition in the power industry, governs Open Access rights. Open Access can be divided into the following categories according to where the buying and selling entities are located:-

Inter-State Open Access:

In this, the buying and selling entities are from separate states, and they are both required to abide by Central Electricity Regulatory Commission(CERC) rules. The purchasing rights under interstate open access may be for Short Term, or for a period of less than one month; Medium Term, or for a period of three months to three years; and Long Term, or for a period of twelve to twenty-five years.

Intra-State Open Access

As implied by the name, in this situation both the buying and selling entities are in the same state. It adheres to rules established by the State Electricity Regulatory Commission (SERC). It can also be divided into three categories: short term, medium term, and long term. The lengths of these terms vary according to the laws in each state.

Electricity buyers and sellers have the choice of bilateral or collective transactions. In a collective transaction, exchanges that have a very minimal margin set up for exchange members facilitate the trading of power. In the case of a bilateral transaction, a Power Purchase Agreement is signed by the seller and the buyer for the purpose of purchasing power at a price that has been mutually agreed upon for a specified period of time. For the purpose of determining tariffs with commercial and industrial clients, many of the major solar firms operating in India under the OPEX model turn to bilateral agreements.

As was previously mentioned, operators using the grid under open access are subject to a variety of fees. These fees may differ from one state to the next & are often lower in states with a stable grid and a supportive regulatory structure. When it comes to solar energy, state-by-state open access fees might range from INR 0.2/KWh in Andhra Pradesh to INR 1.5/KWh in Uttarakhand. Currently, Madhya Pradesh, Andhra Pradesh, Karnataka and Chhattisgarh are home to the majority of open access solar projects in India.

Long-term open access projects may become feasible in the future with the help of a supportive regulatory framework from the state power authorities and improved grid reliability. The situation of power trading in the nation will undoubtedly improve as a result of these improvements, which will encourage more projects from renewable energy companies who are currently assuming enormous upfront risks. 

Open Access has a lot to do in the power sector and investing is never a bad option. GSE Renewables is the best solution for you if you are in the lookout for a company which can provide open access for your business. Our company will be more than happy to help you in giving you the best facilities.

How Does Open Access Work in Electricity?

Open access in electricity is a transformative model that allows large energy consumers in India, typically those with a connected load of 1 MW or more, to purchase power directly from the open market rather than being bound to local distribution companies. This approach supports cost reduction, promotes cleaner energy use, and drives competition in the power sector.

Key Steps in Open Access Electricity India

Power Purchase Agreements (PPAs): Consumers sign long or short term PPAs with independent power producers, power exchanges or solar farms under solar open access. These agreements define the volume, price & duration of electricity supply.

Transmission and Wheeling: Electricity is transmitted across state or national grids from the generation point to the consumer’s site using existing infrastructure. Consumers pay wheeling and transmission charges, enabling grid access—this is the backbone of open access in power sector operations.

Scheduling and Dispatch: Power is scheduled daily through coordination with State Load Dispatch Centers (SLDCs) and Regional Load Dispatch Centers (RLDCs), ensuring grid stability and demand-supply alignment.

Infrastructure Setup: Consumers install special energy meters and remote monitoring systems to track real-time consumption under open access electricity India norms.

Regulatory Oversight

  • The entire process is regulated by bodies such as:
  • Central Electricity Regulatory Commission (CERC)
  • State Electricity Regulatory Commissions (SERCs)
  • SLDCs and RLDCs

Technical and Financial Requirements for Open Access in Electricity

Open access in electricity gives large consumers the power to choose their energy suppliers and access cost-effective energy, including clean options like solar open access. However, to avail this benefit, certain technical and financial criteria must be met.

Technical Requirements

Advanced Metering Infrastructure (AMI): Consumers must install secure & smart meters capable of recording time-of-day energy usage. This ensures precise billing and load monitoring, both essential for participating in open access electricity India.

Grid Compliance and Synchronization: The consumer’s facility must adhere to national grid standards. This includes proper synchronization with the utility grid, stable voltage levels, and compliance with safety protocols and connectivity norms laid out under open access in power sector regulations.

Financial Requirements

Transmission and Wheeling Charges: Consumers must pay fees to use the national or state transmission and distribution networks. These charges ensure fair compensation to utilities for infrastructure usage.

Cross-Subsidy Surcharge (CSS): Since local utilities often subsidize residential or agricultural consumers, commercial and industrial users opting for open access may be required to pay a CSS to balance lost revenue.

Scheduling and Operation Charges: Additional charges cover the administrative effort required to coordinate power flow, schedule electricity dispatch, and maintain grid stability.
