Telangana Hikes Open Access Charges for FY 2026-27
⚡ Quick Read
- What happened: The TGERC has maintained existing retail electricity tariffs for FY 2026-27 while implementing hikes in cross-subsidy surcharges and open access levies.
- Why it matters: Increased open access charges directly impact the ROI for C&I consumers and developers planning behind-the-meter or open-access solar projects in Telangana.
- Watch: Further regulatory notifications regarding specific grid connectivity norms and potential impacts on green energy open access (GEOA) applications.
Background and Context
The Telangana Electricity Regulatory Commission (TGERC) has officially announced its tariff order for the financial year 2026–27. While the commission has opted to maintain the existing retail electricity tariff structure for domestic, commercial, and industrial consumers, it has introduced significant revisions to open access–linked charges. These adjustments, specifically regarding cross-subsidy surcharges and additional surcharges, are critical for stakeholders operating within the state’s power market, particularly those utilizing open access for renewable energy procurement.
Key Details
Under the new order, industrial and commercial retail tariffs remain stable. For HT-I(A) Industry General, energy charges stay at ₹7.65/kWh at 11 kV, ₹7.15/kWh at 33 kV, and ₹6.65/kWh at 132 kV and above. Commercial consumers (HT-II(A)) maintain energy charges of ₹8.80/kWh at 11 kV, ₹8.00/kWh at 33 kV, and ₹7.80/kWh at 132 kV.
However, the financial landscape for open access has shifted. For the Southern Power Distribution Company of Telangana, the cross-subsidy surcharge for HT-I Industry has increased across all voltage levels; for instance, the 11 kV surcharge rose to ₹1.98/kWh from ₹1.82/kWh. Similarly, commercial HT-II surcharges saw hikes, with the 132 kV segment rising to ₹2.34/kWh from ₹1.79/kWh. Additionally, consumers opting for green energy must now pay an additional tariff of ₹0.66/kWh. The commission also introduced a time-of-day (ToD) tariff, imposing an extra ₹1.50/kWh during peak hours (6 am–10 am and 6 pm–10 pm) and offering a ₹0.50/kWh rebate during off-peak hours (10 am–6 pm).
What This Means for EPCs and Developers
For EPC contractors and solar developers, these changes necessitate a re-evaluation of project feasibility for C&I clients. The hike in cross-subsidy surcharges effectively narrows the cost-benefit gap for open access solar projects. Developers must now incorporate these higher levies into their financial models when pitching solar open access solutions to industrial clients. The introduction of specific ToD tariffs also creates a new opportunity for energy storage integration, as clients may look to BESS solutions to shift consumption away from peak hours to avoid the ₹1.50/kWh premium.
What Happens Next
Market participants will closely monitor how these increased surcharges influence the uptake of new open access applications in the state. As the India renewable energy sector continues to mature, regulatory bodies are increasingly balancing the financial health of DISCOMs with the need for green energy adoption. Developers should expect continued scrutiny of open access charges as states attempt to protect DISCOM revenues while meeting national decarbonization targets.
