\"Industrial<\/figure>\n\n\n\n

A Telangana industrial power bill consists predominantly of energy charges, demand charges and, for many HT sites, time-of-day adders. Solar behind the meter initially goes on the energy line. The facility produces on the DISCOM meter side of the factory. The machines employ those units before anything gets imported. That\u2019s the cheapest solar unit you will ever acquire as it bypasses the whole retail tariff not just a narrower export credit.<\/p>\n\n\n\n

Net metering is the settlement layer on top of it. It\u2019s not a different technology. This is how TSSPDCL or TSNPDCL measures what you still import after the roof has done its job and how surplus is credited.<\/p>\n\n\n\n

Quick Answer Box<\/strong><\/h2>\n\n\n\n

Build behind-the-meter solar to meet daytime process load, not to fill every sheet of PEB roof. The rooftop rule of 2025 has capped the ceiling of net metering for the commercial and industrial sector at 500 KW and 80 per cent of the sanctioned load. Gross metering might be upto 1 MW. If you are under TSSPDCL \/ TGSPDCL, apply on the southern portal else if you are under TSNPDCL \/ TGNPDCL apply on the northern portal. Different office, same TGERC rules. Size for own use. Export is a residue, not a business case.<\/p>\n\n\n\n

What Behind-the-Meter Means on an Industrial Service<\/strong><\/h2>\n\n\n\n

Behind-the-meter means the solar array is connected to your low-voltage or plant bus, on your side of the utility meter. Generation reduces the number of units the meter sees coming in. If the array is less than daytime load, nearly all the unit is self-consumed and there is no discussion about export.<\/p>\n\n\n\n

Under Solar net metering Telangana rules, if the array is larger than instantaneous load, surplus can flow out through a bi-directional meter. But that surplus is valuable. It\u2019s just not priced like the unit that never left the shop floor.<\/p>\n\n\n\n

The state already has a third paradigm in place \u2014 huge behind-the-meter plants that use most or all of the generating on site, with limited or closely controlled export. Industry estimates for Telangana\u2019s behind-the-meter solar are in the few-hundred megawatt range with some single sites well above the net-metering cap. For the larger plants the synchronisation & documentation is slower than a conventional 100\u2013500 kW rooftop file<\/p>\n\n\n\n

Do not confuse this with open access. The open access wheels power from somewhere else on the grid<\/a> and pay a charge stack. Behind the meter solar is on your property.<\/p>\n\n\n\n

How the Bill Actually Falls<\/strong><\/h2>\n\n\n\n

In newer retail formations of TGERC, industrial energy rates for HT have been around \u20b97.65 per unit for 11 kV and \u20b97.15 per unit for 33 kV, with commercial HT rates being higher. FY 2026-27 also applies a peak ToD surcharge of Rs 1.50\/unit in morning and evening blocks and Rs 0.50 refund in the 10 am-6 pm window.<\/p>\n\n\n\n

So a noon unit consumed by a compressor or a spinning line falls inside the rebate window and avoids the base energy price. The same unit exports, then imports after 6 p.m., with the peak adder. That\u2019s why industrial design starts with the load curve, not with a roof area calculator.<\/p>\n\n\n\n

Just because you have panels up doesn\u2019t mean demand charges disappear. A battery can snub brief spikes . Solar alone doesn\u2019t cut back all the kVA surges.<\/p>\n\n\n\n

A second save, assuming the plant is hybrid, is the run time of diesel during feeder dips. A typical grid-tie array shuts down amid an outage. Budget honestly.<\/p>\n\n\n\n

PM Surya Ghar cash subsidy not available on industrial meter. The fiscal lever is accelerated depreciation of the asset, depending on the tax situation of the corporation.<\/p>\n\n\n\n

Capacity Rules That Bind the Design<\/strong><\/h2>\n\n\n\n

Under the TGERC roof framework in 2025\u201326:<\/p>\n\n\n\n

For net-metered rooftop, industrial, commercial and other consumers can set up to 80 percent of the sanctioned load<\/a> or contracted demand. Net metering itself has a maximum of 500 kW. The gross metering can be up to 1 MW. Connections to residential and government can be up to 100 per cent of the sanctioned load. There is group and virtual net metering for defined lesser capacities. A consumer cannot have net and gross metering on the same arrangement.<\/p>\n\n\n\n

Older DISCOM FAQ pages still talk about a 1 MWp ceiling and the 80 percent industrial limit. For new files apply 2025 regulation. If portal form is different then ask the circle office which circular they are applying.<\/p>\n\n\n\n

A technically legal size may yet be blocked by feeder and transformer headroom. Feasibility is not a rubber stamp.<\/p>\n\n\n\n

TSSPDCL Net Metering Status and Process<\/strong><\/h2>\n\n\n\n

TSSPDCL Net Metering status<\/strong> is a fact at the file level, not a statewide hue on a dashboard. Southern Power (TSSPDCL \/ TGSPDCL<\/a>) includes Hyderabad, Rangareddy, Medchal-Malkajgiri and the southern belt. Applications should be submitted through www.tssouthernpower.com<\/strong><\/a> and the applicable CSC or section office.<\/p>\n\n\n\n

The official solar FAQs include an application fee of Rs 2,500 for LT and Rs 15,000 for HT (11 kV or 33 kV or capacity beyond 56 kW) The documents would normally have the current bill, identity and title papers and later the work-completion report, and an agreement on stamp paper. DISCOM replaced the unidirectional meter with bi-directional meter of sanctioned load rating.<\/p>\n\n\n\n

Technical feasibility of a suitable application shall be assessed within 21 working days. In Hyderabad circles industry practice is to run longer on HT files as drawings, earthing notes and generation-meter configurations are reviewed in detail. First pass rejections are focused on incomplete single line designs and missing structural or earthing sheets, not on the premise of industrial solar.<\/p>\n\n\n\n

The section inspects the installation, seals the meter and produces commissioning papers. Exported units are not net-metered energy until that seal is affixed.<\/p>\n\n\n\n

After filing, status is the unique registration number on the portal and the physical file in the subdivision. There is no single public map which claims \u201call Hyderabad industry is approved\u201d. Keep your URN.<\/p>\n\n\n\n

TSNPDCL Solar Net Metering<\/strong><\/h2>\n\n\n\n

TSNPDCL Solar Net metering<\/strong> is controlled by the same TGERC. The northern firm (TSNPDCL \/ TGNPDCL) caters to Warangal, Karimnagar, Nizamabad, Adilabad and other areas. The website is www.tsnpdcl.in<\/strong><\/a>. The same framework applies to fees, the 80 percent industrial cap, the bi-directional meter and the 21-day feasibility clock.<\/p>\n\n\n\n

Residential LT files can be faster as volume is less than Hyderabad. Large industrial estates still require the same HT designs, CEIG interface where capacity dictates and a vendor who will stand in the section office.<\/p>\n\n\n\n

If the factory group has plants in both DISCOMs, then take them as two files. A Warangal commissioning letter does not go to Hyderabad.<\/p>\n\n\n\n

Most Telangana factories should live in the first two rows. Jumping to a multi-megawatt behind-the-meter plant without a synchronisation plan is how projects stall after the steel is on the roof.<\/p>\n\n\n\n

How to Cut Cost without Chasing the Wrong Credit<\/strong><\/h2>\n\n\n\n

Match array size to weekday daytime Kw then cut for shade, structure and the 80 percent guideline. If it\u2019s 280 kW and the roof can absorb 600kW then go closer to 280-350 kW unless storage or a second shift will consume the rest.<\/p>\n\n\n\n

Do not size as monthly units \/ 120 as if nite load was solar. Nite load is a grid or diesel concern until you add a battery.<\/p>\n\n\n\n

Keep a generation counter and a clean portal login. A facility that can\u2019t show string-level drop will dispute accounts if the bill isn\u2019t 40 percent lower in July.<\/p>\n\n\n\n

EPC scope should include DISCOM cooperation. The normal delay is an HT file that leaves drawings to the manufacturing electrical contractor.<\/p>\n\n\n\n

Check eligibility of proposed modules for ALMM interconnection. Cheap stack that can not link is not a cost decrease.<\/p>\n\n\n\n

Why behind-the-meter solar still pays off as export policy tightens \u2013 the first row You are not selling power to DISCOM as a commercial entity. You’re producing less units for the HT meter while the shop is running.<\/p>\n\n\n\n

Industries that view net metering as the product and the roof as an afterthought overbuild, wait on feasibility and then complain that credited units are not worth \u20b97. Those that treat behind-the-meter self-use as the product and net metering as the settlement method file a smaller, cleaner application, and see the energy line move within the first clean quarter after commissioning.<\/p>\n\n\n\n

People Also Ask<\/strong><\/h2>\n\n\n\n

What is behind-the-meter solar in Telangana?<\/strong><\/h3>\n\n\n\n

It is a solar plant linked on the factory side of the TSSPDCL or TSNPDCL meter so generation serves on-site load first. Then, if allowed, net metering accounts for any residual import and export. This is not open access.<\/p>\n\n\n\n

How does Solar net metering Telangana work for industry?<\/strong><\/h3>\n\n\n\n

Import and export are recorded using a bi-directional meter. Self consumed units are not registered as imports. Surplus will be credited as per TGERC rooftop guidelines. Industrial net metered size is limited to 500 kw<\/a> and 80% of sanctioned load.<\/p>\n\n\n\n

How do I check TSSPDCL Net Metering status?<\/strong><\/h3>\n\n\n\n

Use the unique registration number on www.tssouthernpower.com<\/strong><\/a> and follow the physical file at your section or CSC. Status is application-specific. Hyderabad circles process more C&I volume than rural southern subdivisions.<\/p>\n\n\n\n

How does TSNPDCL Solar Net metering differ?<\/strong><\/h3>\n\n\n\n

The regulation is the same. The portal is www.tsnpdcl.in<\/strong><\/a> and the offices sit in the northern districts. Fees, caps and the 21-day feasibility clock follow the same framework. File each service connection separately.<\/p>\n\n\n\n

What is the application fee for industrial net metering?<\/strong><\/h3>\n\n\n\n

DISCOM FAQs list \u20b92,500 for LT and \u20b915,000 for HT services. Confirm GST and any current circular on the portal before payment.<\/p>\n\n\n\n

Can an industry install more than 500 kW behind the meter?<\/strong><\/h3>\n\n\n\n

Larger on-site plants exist, but net-metering settlement at that size is not the standard 2025 path. Synchronisation and CEIG documentation become the bottleneck. Model self-consumption and export limits before ordering modules.<\/p>\n\n\n\n

Do factories get the PM Surya Ghar subsidy?<\/strong><\/h3>\n\n\n\n

No. That cash subsidy is for residential connections. Industrial projects rely on bill savings and, where eligible, accelerated depreciation.<\/p>\n\n\n\n

Who handles industrial behind-the-meter EPC and DISCOM filings in Telangana?<\/strong><\/h3>\n\n\n\n

Samraj Solar is a specialised Solar EPC Company established in 2014 by Abburi Ajay Kumar with its Head office at H.No. 3-5-242\/1, Krishna Nagar, Moula Ali, Hyderabad and Branch office at Guntur. The company has undertaken projects for residential, commercial, industrial and institutional clients across Telangana and Andhra Pradesh. It is a channel partner of Tata Power Solar and provides engineering, procurement, construction and documentation support for industrial rooftop plants<\/a> under TSSPDCL and TSNPDCL procedures.<\/p>\n\n\n\n

Factories can start with latest twelve HT bills and sanctioned load and roof photo. That\u2019s enough to test 80 percent of the load against the daytime kW before anyone books a crane.<\/p>\n","protected":false},"excerpt":{"rendered":"
