Not sure which DISCOM covers your property? Check your electricity bill — it will clearly state whether it is issued by TGSPDCL or TGNPDCL. The Service Connection (SC) number format also differs: TGSPDCL and TGNPDCL use distinct numbering series. Sri Ishaan Solar identifies your DISCOM during the site survey so you never have to navigate this yourself.

TGSPDCL vs TGNPDCL — Net Metering Process Comparison

Both DISCOMs follow the Telangana Electricity Regulatory Commission (TERC) net metering regulations and the national PM Surya Ghar portal framework. The core process is the same; the differences are mostly in volume, timelines, and local office handling:

TGSPDCL Net Metering Application — Step-by-Step Process (Hyderabad)

For properties in Hyderabad and other TGSPDCL areas, here is the complete net metering process from solar installation to bi-directional meter activation:

  1. Install solar system with a TGREDCO-registered installer. This is the prerequisite. Only systems installed by TGREDCO-registered companies (like Sri Ishaan Solar, Reg. No. TSRE260936) are eligible for TGSPDCL net metering approval. The installer must use ALMM-listed panels.
  2. PMSG Portal Registration (for residential systems). Your installer registers the installation on pmsuryaghar.gov.in — the national PM Surya Ghar Muft Bijli Yojana portal. This is mandatory for subsidy eligibility and also feeds into the DISCOM's workflow. Your Service Connection (SC) number, system capacity, panel details, and installer's TGREDCO number are entered here.
  3. File net metering application with TGSPDCL. Submit the net metering application at the concerned TGSPDCL Electrical Division Office or through the TGSPDCL online portal. Documents required include: latest electricity bill, proof of ownership/NOC, system technical specification sheet, single-line diagram, ALMM certificate, and installer's TGREDCO certificate. Sri Ishaan Solar prepares and files this on your behalf.
  4. TGSPDCL processes the application. The local TGSPDCL Electrical Division reviews your application for completeness and technical compliance. Processing typically takes 5–10 working days. If documents are complete and the system specification is within sanctioned load, the application moves to inspection scheduling.
  5. TGSPDCL physical site inspection. A TGSPDCL engineer visits your property to inspect the installation — verifying panels, inverter, wiring, earthing, and DC/AC disconnect arrangements against the submitted single-line diagram. The inspection is typically scheduled within 15–30 working days of application acceptance. Sri Ishaan Solar coordinates the inspection date and ensures the installation is ready.
  6. Inspection approval and technical sanction. If the installation passes inspection, TGSPDCL issues a technical sanction for net metering. If minor corrections are noted, the installer rectifies them and requests a re-inspection. Sri Ishaan Solar handles any inspection observations at no additional cost within the warranty period.
  7. Bi-directional meter installation. TGSPDCL replaces your existing unidirectional meter with a bi-directional (import-export) meter. This is done by TGSPDCL's metering team and typically takes 5–15 working days after technical sanction. The new meter records both units imported from the grid and units exported to the grid separately.
  8. Net metering commissioning and subsidy credit. Once the bi-directional meter is active, your system is officially commissioned under net metering. PMSG subsidy (up to ₹78,000) is credited to your bank account by MNRE through the portal, typically within 30 days of TGSPDCL's commissioning confirmation.

TGNPDCL Net Metering Application — Process for Karimnagar, Warangal & Northern Districts

The TGNPDCL process follows the same framework as TGSPDCL with a few practical differences due to lower application volume and different local office structures:

  1. Install solar system with a TGREDCO-registered installer. Same requirement as TGSPDCL — only TGREDCO-registered installers with ALMM-listed panels are eligible. Sri Ishaan Solar is registered and handles TGNPDCL applications across all northern districts.
  2. PMSG Portal Registration. Same national portal (pmsuryaghar.gov.in) is used. The portal automatically routes the application to TGNPDCL based on the consumer's Service Connection number.
  3. File net metering application with TGNPDCL. Application is submitted at the relevant TGNPDCL Electrical Division Office (in Karimnagar, Warangal, Nizamabad, Khammam, or other district headquarters) or through the TGNPDCL online portal (tsnpdcl.in). Same documentation set as TGSPDCL.
  4. TGNPDCL application processing. TGNPDCL Electrical Division reviews the application. Because TGNPDCL handles fewer solar applications than TGSPDCL's Hyderabad offices, processing can be faster in many areas — typically 5–7 working days.
  5. TGNPDCL physical site inspection. A TGNPDCL engineer visits the site. Inspection scheduling in TGNPDCL areas (particularly smaller towns like Siddipet, Sangareddy, Medak) can be faster than TGSPDCL's Hyderabad offices — typically within 10–25 working days.
  6. Inspection approval and technical sanction. Same process as TGSPDCL — inspection pass triggers technical sanction for net metering.
  7. Bi-directional meter installation. TGNPDCL installs the bi-directional meter — typically within 5–10 working days of sanction in northern districts.
  8. Net metering commissioning and PMSG subsidy credit. Commissioning confirmation is sent to MNRE via the portal, and subsidy is credited to the bank account registered on pmsuryaghar.gov.in within approximately 30 days of confirmation.

How Net Metering Interacts with the PM Surya Ghar Subsidy

Many buyers confuse net metering approval with subsidy disbursement. These are two separate but linked processes:

Key distinction:
  • Net metering approval — granted by TGSPDCL or TGNPDCL after installation and site inspection. This activates your bi-directional meter so surplus units are credited to your electricity bill.
  • PMSG subsidy disbursement — granted by MNRE (central government) after your DISCOM's commissioning confirmation is uploaded to pmsuryaghar.gov.in. The subsidy of up to ₹78,000 is credited directly to your bank account.
  • Timeline: You cannot receive the PMSG subsidy without first getting DISCOM net metering approval (commissioning). The subsidy approval from MNRE typically follows the DISCOM commissioning confirmation by 15–30 days.
  • Your role: Virtually nothing — Sri Ishaan Solar manages the entire portal workflow, DISCOM coordination, inspection scheduling, and subsidy documentation on your behalf.

System Size Limits for Net Metering in Telangana

Both TGSPDCL and TGNPDCL follow TERC regulations on the maximum solar system capacity permitted under net metering for each consumer category:

Consumer CategoryMax System Capacity (Net Metering)Notes
Residential (Single Phase)Up to sanctioned load, typically up to 10kWMost homes on LT single-phase have 4kW–10kW sanctioned load
Residential (Three Phase)Up to sanctioned load, typically up to 25kWFor larger homes, bungalows, or 3-phase supply
Commercial / Industrial (LT)Up to sanctioned loadShops, offices, small factories on LT supply
Commercial / Industrial (HT)Per TERC regulations, up to 100% of sanctioned demandLarge commercial/industrial consumers on HT supply
Common mistake: Installing a solar system larger than your sanctioned load will fail DISCOM inspection. For example, if your sanctioned load is 5kW, you cannot get net metering approved for a 10kW system without first upgrading your sanctioned load — which requires a separate application to TGSPDCL/TGNPDCL. Sri Ishaan Solar checks your sanctioned load during the site survey and recommends an appropriately-sized system.

Common Net Metering Issues and How to Avoid Them

Based on our experience handling TGSPDCL and TGNPDCL net metering applications across Hyderabad and Telangana, the most common issues that delay approval are:

Top reasons for DISCOM inspection rejection or delay:
  • Non-ALMM panels — panels not on the MNRE ALMM list will fail inspection. Sri Ishaan Solar only installs ALMM-listed panels.
  • System size exceeds sanctioned load — a 6kW system on a 4kW sanctioned load connection will be rejected. We size systems within sanctioned load.
  • Missing or incorrect single-line diagram — DISCOM engineers verify the electrical diagram against the actual installation. Discrepancies cause re-inspection.
  • Improper earthing — both AC and DC earthing are verified during inspection. Missing earthing is a common cause of rejection and a safety hazard.
  • Inverter not grid-synchronised — the inverter must have anti-islanding protection and be grid-synchronised at the time of inspection.
  • Non-TGREDCO registered installer — if your installer is not TGREDCO-registered, the application itself is invalid. Sri Ishaan Solar is TGREDCO registered (TSRE260936).

Frequently Asked Questions — TGSPDCL vs TGNPDCL Net Metering

Which DISCOM covers Hyderabad for solar net metering — TGSPDCL or TGNPDCL?
Hyderabad city and most of Ranga Reddy, Medchal-Malkajgiri, Nalgonda, and Mahbubnagar districts fall under TGSPDCL. If you are in Bandlaguda, Kukatpally, Madhapur, LB Nagar, Uppal, Shamshabad, Kompally, Miyapur, or any other central Hyderabad locality, your DISCOM is TGSPDCL. The quickest way to confirm is to check your electricity bill — it clearly states the issuing company. Sri Ishaan Solar identifies your DISCOM during the free site survey.
How do I apply for net metering with TGSPDCL in Hyderabad?
For TGSPDCL net metering: install your solar system with a TGREDCO-registered installer, register on pmsuryaghar.gov.in, and file the net metering application with TGSPDCL (either online via tssouthernpower.com or at your local Electrical Division Office). TGSPDCL will conduct a site inspection, approve the application, and install a bi-directional meter. Sri Ishaan Solar manages this entire process on your behalf as part of our standard installation service — at no extra charge.
Is the net metering process different between TGSPDCL and TGNPDCL?
The process framework is identical — both follow TERC net metering regulations and the pmsuryaghar.gov.in workflow. The main practical difference is timeline: TGSPDCL handles a much higher application volume (due to Hyderabad's population) and can take 30–60 working days, while TGNPDCL in smaller northern towns may complete the process in 25–50 working days. Both require a TGREDCO-registered installer, ALMM-listed panels, and a site inspection.
How long does TGSPDCL net metering approval take in Hyderabad in 2026?
Based on our experience with TGSPDCL applications in Hyderabad: application to bi-directional meter activation typically takes 30–60 working days (6–12 weeks). This covers: application filing (1–2 days), TGSPDCL processing (5–10 working days), site inspection scheduling and execution (15–30 working days), inspection approval (5–10 working days), and meter installation (5–15 working days). During peak periods (Q4 calendar year), timelines can extend. Sri Ishaan Solar tracks every application and follows up proactively.
What documents are required for TGSPDCL or TGNPDCL net metering application?
Standard documents: (1) Completed application form with consumer Service Connection number, (2) Latest electricity bill copy, (3) Proof of ownership or NOC from landlord/housing society, (4) System technical specifications (panel datasheet, inverter datasheet, system capacity), (5) Single-line diagram of the solar installation, (6) ALMM certificate for the panels, (7) Installation certificate from a TGREDCO-registered installer, (8) ID proof (Aadhaar/PAN). Sri Ishaan Solar prepares all documentation and submits on your behalf.
What is the net metering tariff credit rate in Telangana in 2026?
In Telangana, both TGSPDCL and TGNPDCL operate net metering on an energy offset basis: units exported to the grid are credited against units imported, at the applicable consumer tariff rate for your category and slab. Surplus credits (when exports exceed imports in a billing period) carry forward. No direct cash payment is made for exported surplus in most residential cases. The exact credit rate depends on your consumer category and tariff slab — check your electricity bill or the TERC tariff order. Sri Ishaan Solar explains this in detail during the site survey.
