Telangana's 2025 rooftop solar rules, explained for homes and communities

What changed

The Telangana Electricity Regulatory Commission's Rooftop Solar PV Grid Interactive Systems Regulation 2025 replaced the 2016 net-metering rules and took effect on 15 November 2025.

Four ways to connect

• Net metering: up to 500 kWp for most consumers.
• Gross metering: up to 1 MWp; all generation is sold to the DISCOM.
• Group net metering: below 100 kWp, for domestic consumers and residential colonies.
• Virtual net metering: share a system's credit across several connections in the same distribution area.

A consumer can't combine more than one arrangement at the same time.

Limits and approvals

• Homes can install up to their full sanctioned load.
• Application fee: ₹2,500 (low tension) or ₹15,000 (high tension).
• The DISCOM must issue feasibility within 15 working days of a complete application.
• DISCOMs publish available transformer and feeder capacity every quarter; approvals are first come, first served.
• The regulation provides for compensation from the DISCOM for delays.
• Approvals are valid for 25 years from grid connection.

What it means for gated communities

Group and virtual net metering let a community share solar credit, for example using clubhouse or common-area solar to offset pumps and street lights. The exact process is still settling in with TGSPDCL, so plan with them before you build.
