UHBVN and Haryana rules for factory solar

Net metering up to 500 kW

Under HERC's 2021 rooftop regulations, net metering is allowed up to 500 kW or your sanctioned load / contract demand, whichever is lower. Larger plants can use gross metering up to contract demand. Consumers drawing open-access power cannot also net-meter.

How surplus units are settled

Since HERC's 2nd Amendment (October 2025), surplus credits carry forward within a 1 October – 30 September settlement period. Credits left at the end are bought by the DISCOM at 90% of the feed-in tariff, so size the plant for daytime self-consumption.

FY2026-27 industrial tariff

HT industrial supply (above 50 kW) pays ₹6.95/kVAh at 11 kV and ₹6.85/kVAh at 33 kV, plus ₹290/kVA/month of contract demand. Electricity duty, municipal tax and FSA are extra. There is no solar-hour rebate in the FY2026-27 schedule.

Applying to UHBVN

UHBVN runs its own rooftop portal (solarconnection.uhbvn.org.in). HERC rules require feasibility within 15 days and a Letter of Approval within 22 days; plants above 20 kWp also need a safety certificate from the Chief Electrical Inspector before commissioning.

Green open access from 100 kW

Consumers with 100 kW or more of contract demand can buy green power through open access; since 2025 several connections in the same operation division can be clubbed to reach 100 kW. FY2026-27 HT charges include ₹0.73/kWh wheeling and ₹1.45/kWh cross-subsidy surcharge.

Payback on a 100 kW rooftop in Rohtak

Item	Value	Basis
System cost	₹23,00,000	100 kW × ₹23,000/kW, ex-GST (Sun Wave reference)
Year-1 generation	1,20,000 units	100 kW × 1,200 kWh/kWp/year (Delhi Solar Policy, 2nd Amendment 2026)
Grid energy charge avoided	₹6.95/kVAh	HT industrial energy charge at 11 kV, FY2026-27 (HERC FY2026-27 order (DHBVN circular D-06/2026))
Year-1 saving	≈ ₹8,34,000	1,20,000 × ₹6.95
Simple payback	≈ 2.8 years	System cost ÷ year-1 saving

Illustrative only. Assumes the factory uses all solar output during working hours and counts the energy charge alone, treating one kVAh as one kWh (unity power factor). It excludes GST, demand charges, surcharges, panel degradation, O&M and financing. Your actual payback depends on your tariff category, load profile and roof.

What Rohtak factories should know

In March 2026 the IMT Udyog Welfare Association, Rohtak said a sharp rise in fixed charges on electricity bills had placed a heavy financial burden on industrialists.

HSIIDC's environmental filing for IMT Rohtak Phase III projects 75.44 MW (94.3 MVA) of power demand and lists general manufacturing, automobile and mechanical units as intended occupants.

Rohtak is in the National Capital Region, so CAQM Direction No. 76 applies: diesel DG sets may run only as backup, and older sets of 41–800 kW need dual-fuel kits or certified emission-control retrofits. Rooftop solar cuts the daytime units a DG set or the grid has to supply.

Frequently Asked Questions

Which electricity board handles solar net metering in IMT Rohtak?

IMT Rohtak and Rohtak's other industrial areas are served by UHBVN's Rohtak operation circle. Net-metering applications are filed on UHBVN's portal, solarconnection.uhbvn.org.in.

How long does UHBVN take to approve rooftop solar for a factory in Rohtak?

HERC rules require UHBVN to check technical feasibility within 15 days of acknowledging a complete application and to issue a Letter of Approval within 22 days. You then have 180 days to install the plant.

Does rooftop solar reduce fixed charges for Rohtak factories?

No. Solar reduces the energy units you buy, at ₹6.95/kVAh for 11 kV HT supply, but the ₹290/kVA/month contract-demand charge stays. The saving comes from avoided energy charges and reduced DG running.

How much does rooftop solar cost for a Rohtak factory?

Sun Wave's reference price is ₹23,000/kW excluding GST at 100 kW, about ₹23 lakh, and ₹22,000/kW at 500 kW, about ₹1.1 crore. The final price follows a site survey.
