Rajasthan Open Access Charges FY 2027: Key Tariff Updates
⚡ Quick Read
- What happened: The RERC has finalized the retail electricity tariff structure for FY 2026-27, setting cross-subsidy surcharges at ₹1.48/kWh and an additional surcharge of ₹0.50/kWh for open access consumers.
- Why it matters: These regulatory updates directly impact the cost-competitiveness of open access solar and wind projects for C&I consumers in Rajasthan.
- Watch: The implementation of the additional ₹0.05/kWh green power premium and its effect on corporate renewable energy procurement demand.
Background and Context
The Rajasthan Electricity Regulatory Commission (RERC) has released its tariff order for the financial year (FY) 2026–27, maintaining a largely stable retail electricity tariff structure while introducing critical adjustments to open access charges. As Rajasthan continues to be a focal point for renewable energy development, these regulatory signals are vital for stakeholders navigating the state’s power market. The order aims to balance the financial health of state distribution companies (DISCOMs) with the operational requirements of industrial and commercial (C&I) consumers.
Key Details
Under the new order, the cross-subsidy surcharge is fixed at ₹1.48/kWh across all voltage levels. To mitigate the impact of stranded fixed costs caused by consumer migration, the Commission has approved an additional surcharge of ₹0.50/kWh. Furthermore, a base fuel and power purchase adjustment surcharge of ₹0.14/kWh has been mandated. A notable development is the introduction of a specific green power premium, where consumers opting for renewable energy will pay an additional ₹0.05/kWh over the applicable tariff.
Wheeling charges have been structured by voltage level to incentivize higher voltage connectivity: ₹1.93/kWh at low tension, ₹0.69/kWh at 11 kV, ₹0.09/kWh at 33 kV, and a minimal ₹0.01/kWh at 132 kV and above. The Commission has also retained voltage rebates, offering 3% at 33 kV, 4% at 132 kV, and 5% at 220 kV, encouraging large-scale industrial consumers to invest in high-voltage infrastructure.
What This Means for EPCs and Developers
For EPC contractors and solar developers, the clarity on wheeling charges and surcharges provides a clearer framework for calculating the Levelized Cost of Energy (LCOE) for open access projects. The aggressive incentivization of high-voltage connectivity (132 kV and above) suggests that future C&I projects should focus on large-scale, high-voltage substations to maximize consumer savings. The additional surcharge of ₹0.50/kWh remains a critical factor that developers must factor into their financial models when pitching open access solutions to industrial clients.
What Happens Next
Stakeholders should monitor the uptake of the green power option, as the ₹0.05/kWh premium is a strategic move to formalize green energy procurement. As Rajasthan solidifies its position as a leader in the India renewable energy sector, these regulatory adjustments will likely serve as a benchmark for other states looking to balance DISCOM stability with the growing demand for corporate renewable energy transition.
