The Telangana Electricity Regulatory Commission (TGERC) notified Regulation No. 1 of 2025 in the Telangana Gazette on 15 November 2025. It covers net metering, group net metering, gross metering, and virtual net metering arrangements for rooftop solar systems connected to Telangana distribution licensees.
What the regulation says for residential connections
- Net metering and gross metering rooftop systems have a 1 kWp minimum system size under the regulation.
- For residential and government consumers, net-metered or gross-metered capacity may not exceed 100% of the consumer's sanctioned load.
- The cumulative rooftop solar capacity for LT consumers connected to a distribution transformer is limited to 50% of that transformer's rated capacity. Local network headroom can therefore affect feasibility.
- Consumers with pending arrears are not entitled to the metering arrangements listed in the regulation.
These are regulatory limits and process conditions, not a design recommendation. A household's system still needs a site assessment and the required distribution-licensee approval.
Application and feasibility process
The regulation directs consumers to submit the relevant application to their distribution licensee. It lists a ₹2,500 processing fee per LT connection and identifies the local Divisional Engineer (Operations) as the nodal contact for the solar metering programme.
After receiving an application, the distribution licensee must acknowledge receipt and notify the consumer of missing documents within 7 working days. It must communicate interconnection feasibility within 15 working days after receiving a proper application. Feasibility depends on the relevant distribution transformer or feeder capacity.
Check the current forms, payment details, and contact office on the official distribution-licensee website before applying.
Residential tariff schedule for FY 2026–27
The TGERC order divides LT-I domestic consumers into categories based on total monthly use. The rates below are the published energy and fixed-charge schedule, effective 1 April 2026 through 31 March 2027.
| Category and monthly use | Energy band | Energy charge | Fixed charge |
|---|---|---|---|
| LT-I(A) Monthly consumption not exceeding 100 units | 0–50 units | ₹1.95 / kWh | ₹10.00 / kW / month |
| LT-I(A) Monthly consumption not exceeding 100 units | 51–100 units | ₹3.10 / kWh | ₹10.00 / kW / month |
| LT-I(B)(i) Monthly consumption above 100 and not exceeding 200 units | 0–100 units | ₹3.40 / kWh | ₹10.00 / kW / month |
| LT-I(B)(i) Monthly consumption above 100 and not exceeding 200 units | 101–200 units | ₹4.80 / kWh | ₹10.00 / kW / month |
| LT-I(B)(ii) Monthly consumption above 200 units | 0–200 units | ₹5.10 / kWh | ₹10.00 / kW / month |
| LT-I(B)(ii) Monthly consumption above 200 units | 201–300 units | ₹7.70 / kWh | ₹10.00 / kW / month |
| LT-I(B)(ii) Monthly consumption above 200 units | 301–400 units | ₹9.00 / kWh | ₹10.00 / kW / month |
| LT-I(B)(ii) Monthly consumption above 200 units | 401–800 units | ₹9.50 / kWh | ₹10.00 / kW / month |
| LT-I(B)(ii) Monthly consumption above 200 units | Above 800 units | ₹10.00 / kWh | ₹50.00 / kW / month |
These are not a flat energy rate or a complete bill estimate. The order says FSA/FCA is extra and electricity duty is excluded from the tariff. It also classifies domestic consumers by total monthly units, so a complete bill calculation needs to model the category and all relevant charges.
The same order separately lists monthly LT-I domestic customer charges by consumption band: ₹40 (0–50 units), ₹70 (51–100), ₹90 (101–200), ₹100 (201–300), ₹120 (301–400), ₹140 (401–800), and ₹160 (above 800). These are additional to the per-kW fixed charge and energy charges. FSA/FCA and electricity duty remain outside this schedule.
Eligible households may also receive a zero bill for monthly use up to 200 units under Gruha Jyothi. Enrollment is household-specific; SolarWise does not infer it. See the TGERC Gruha Jyothi order.
Tariff source: Retail Supply Tariff Order for FY 2026–27, dated 30 March 2026, Table 3-52 and §4.2. Effective 2026-04-01 to 2027-03-31; checked 15 October 2026.How exported units are treated
Under net metering, exported units offset imported units in the billing period. When exports exceed imports, the excess is settled at a rate based on the lowest tariff among solar PPAs, PSAs, or PUAs entered by Telangana distribution licensees under section 63 in the preceding financial year. If no such rate exists, the regulation uses the latest previous financial year. TGERC is to notify the settlement rate each year.
The regulation also says a consumer with net exports receives a monthly minimum bill. When imports exceed exports, the bill is raised after exported units are credited; other charges, taxes, duties, or cesses allowed by the Commission or Government may still apply to net billed units.
What this means for an estimate
The regulation helps define how a system can connect and how energy is accounted for, but it does not establish what a particular roof will generate, what an installer will charge, or what every household bill will become. System yield, household use, tariff category, eligibility-based benefits, and the current export rate all matter.
