How Indian Industries Save with Open Access Power
For many industrial businesses in India, electricity is no longer just another operational expense—it has become one of the most significant factors influencing profitability. Rising tariffs, increasing energy consumption, and growing pressure to improve sustainability performance have made power procurement a strategic business decision rather than a routine utility purchase.
Whether it’s a manufacturing plant, textile mill, pharmaceutical facility, food processing unit, or data centre, electricity often accounts for a substantial portion of operating costs. In energy-intensive industries, power expenses can represent 20% to 40% of total production costs. Unlike raw materials, labour, or logistics, electricity tariffs are largely outside a company’s control, leaving businesses exposed to annual tariff hikes and regulatory changes.
This is precisely why Open Access power has emerged as one of the most attractive opportunities for industrial consumers across India. By enabling eligible businesses to purchase electricity directly from renewable energy generators, Open Access offers the potential for significant cost savings, long-term price stability, and improved sustainability performance.
But the question remains: how much can industries actually save?
Why Are Industrial Electricity Costs So High?
To understand the value of Open Access power, it is important to first understand why industrial electricity costs are often significantly higher than the actual cost of generating electricity.
India’s electricity pricing framework operates on a cross-subsidy model. Under this structure, residential and agricultural consumers are often charged lower tariffs, while commercial and industrial consumers pay higher rates to compensate for the revenue gap. As a result, industries frequently pay tariffs that exceed the actual cost of power generation and delivery.
For many industrial consumers, electricity tariffs can range between ₹8 and ₹10 per unit, depending on the state, consumption profile, and applicable charges. While these costs continue to rise, businesses have limited flexibility to negotiate pricing or explore alternative procurement models through traditional utility arrangements.
Open Access changes this dynamic by allowing eligible consumers with a contract demand of 100 kW or more to purchase electricity directly from renewable energy generators. Instead of being entirely dependent on DISCOM tariffs, businesses gain access to competitively priced renewable energy sourced from solar and wind projects.
What Is Open Access Power?
Open Access is a regulatory framework that enables large electricity consumers to procure power directly from generators through the existing transmission and distribution network.
Rather than purchasing all their electricity from a local DISCOM, businesses can enter into long-term Power Purchase Agreements (PPAs) with renewable energy developers. The electricity continues to flow through the same grid infrastructure, ensuring reliability and continuity of supply. What changes is the commercial arrangement behind the power being consumed.
This model allows industries to benefit from lower renewable energy generation costs while maintaining access to the existing electricity network.
How Much Can Industries Save?
The financial impact of Open Access power can be substantial, particularly for businesses with high electricity consumption.
Consider an industrial facility consuming 10 lakh units of electricity every month.
Scenario 1: Conventional DISCOM Power
- Monthly Consumption: 10,00,000 units
- Average Tariff: ₹9.00 per unit
- Monthly Electricity Cost: ₹90 lakh
- Annual Electricity Cost: ₹10.8 crore
Scenario 2: Open Access Renewable Power
- Monthly Consumption: 10,00,000 units
- Effective Landed Cost: ₹5.50 per unit
- Monthly Electricity Cost: ₹55 lakh
- Annual Electricity Cost: ₹6.6 crore
Potential Savings
- Monthly Savings: ₹35 lakh
- Annual Savings: ₹4.2 crore
For most businesses, ₹4.2 crore annually is not a minor operational improvement—it is capital that can be redirected toward expansion, technology upgrades, workforce development, debt reduction, or profitability enhancement.
While actual savings vary depending on location, state regulations, and consumption patterns, many industrial consumers achieve electricity cost reductions ranging from 20% to 40% through Open Access procurement.
Factors That Influence Open Access Savings
The exact level of savings depends on several factors.
State Regulations
Open Access charges, banking provisions, wheeling fees, and surcharges vary across states. As a result, the financial benefits may differ between locations such as Gujarat, Maharashtra, Karnataka, Tamil Nadu, and Rajasthan.
Electricity Consumption Profile
Businesses with consistent and predictable electricity consumption often achieve stronger economics under Open Access arrangements.
Procurement Model
Industries can procure renewable power through multiple structures, including:
- Third-Party Open Access
- Group Captive Models
- Captive Power Projects
Each model offers different financial and regulatory advantages.
Applicable Charges
The final landed cost of Open Access power includes various components such as:
- Transmission Charges
- Wheeling Charges
- Banking Charges
- Cross Subsidy Surcharge (where applicable)
- Additional Surcharges
A detailed feasibility assessment is essential to determine actual savings.
The Long-Term Advantage: Price Stability
While immediate savings attract attention, one of the most valuable benefits of Open Access is long-term price certainty.
Renewable energy PPAs are commonly structured for 15 to 25 years. This enables businesses to lock in predictable energy costs and reduce exposure to future tariff escalations.
Unlike conventional grid power, where tariff revisions can occur regularly, Open Access agreements provide visibility over future energy expenses. This helps finance teams improve budgeting accuracy, strengthen forecasting capabilities, and reduce operational risk.
Over time, the cumulative impact of tariff stability can create a significant competitive advantage. Businesses that secure lower energy costs today may enjoy years of improved margins compared to competitors that remain fully dependent on conventional utility tariffs.
Sustainability Benefits Beyond Cost Savings
Open Access power delivers more than financial savings. It also supports corporate sustainability and decarbonisation goals.
Many domestic and international customers increasingly evaluate suppliers based on environmental performance. Renewable energy procurement helps businesses demonstrate measurable progress toward sustainability commitments through:
- Reduced carbon emissions
- Lower Scope 2 emissions
- Improved ESG performance
- Stronger sustainability reporting
- Enhanced brand reputation
For export-oriented industries and companies operating within global supply chains, renewable energy adoption is becoming an important factor in maintaining competitiveness and meeting buyer expectations.
Which Industries Benefit the Most?
Open Access power is particularly attractive for businesses with significant electricity consumption.
Industries commonly benefiting from Open Access include:
- Manufacturing
- Textiles
- Pharmaceuticals
- Steel
- Cement
- Chemicals
- Food Processing
- Cold Storage
- Warehousing and Logistics
- Data Centres
If electricity represents a major component of operating costs, Open Access is worth evaluating as part of a broader energy procurement strategy.
Final Thoughts
As energy costs continue to rise, industrial businesses are increasingly exploring ways to improve operational efficiency and strengthen profitability. Open Access power offers a practical solution by combining lower electricity costs, long-term price stability, and sustainability benefits within a single procurement framework.
For many industries, the opportunity extends far beyond reducing monthly electricity bills. It is about gaining greater control over one of the largest operating expenses, improving competitiveness, and positioning the business for long-term growth in an increasingly sustainability-driven economy.
Understanding the true savings potential begins with a detailed assessment of your current electricity consumption, tariff structure, and regulatory environment. For businesses that meet the eligibility criteria, Open Access power may represent one of the most impactful financial decisions they can make.
