Industrial Solar in Madhya Pradesh: Net Metering (2026)

Direct answer

Madhya Pradesh industry installs rooftop solar under the MPERC GIRES (Grid Interactive Renewable Energy Systems) Regulations, Revision-II 2024. Net metering is available up to 500 kW for all consumer categories (within contract demand/sanctioned load); net-metered systems are exempt from banking, wheeling, CSS and additional surcharge but are not eligible for open access. MP adds a rule most states don't have: cumulative renewable capacity at a distribution transformer is capped at 80% of its rating, and DISCOMs must publish transformer-level headroom.

The GIRES 2024 framework in practice

GIRES Revision-II 2024 consolidated net metering, group net metering, virtual net metering and gross metering into one regulation with first-come-first-served allocation (MPERC order text; Energetica India, Apr 2024):

• 500 kW net metering cap across categories; prosumers already above 500 kW keep their grandfathered status. Minimum system size is 1 kW.
• Transformer headroom: a prosumer's renewable capacity cannot exceed 80% of the feeding distribution transformer's rating (HT consumers) or 80% of cumulative transformer capacity (for the transformer as a whole). DISCOMs must publish headroom annually - check it before sizing your plant.
• Charges: net-metered and gross-metered prosumers pay no banking charges, wheeling charges, CSS or additional surcharge. GNM/VNM beneficiaries do attract wheeling and surcharges.
• ToD settlement: prosumers on time-of-day tariffs get consumption in each ToD block offset by injection in the same block - which rewards plants sized for daytime load alignment.

Beware of compliance-portal claims that MP allows "C&I net metering up to 1 MW" - the operative GIRES cap is 500 kW; only gross metering extends to 1 MW.

MP tariffs and the FY 2025-26 reset

MPERC's State DISCOMs retail tariff order for FY 2025-26 (29 March 2025, Petition 72/2024) raised fixed and energy charges across industrial, non-industrial, commercial and power-intensive categories after DISCOMs sought a 7.52% increase (MPERC order, Mar 2025). Illustrative HT industrial energy charges from MPIDC-licensed areas (Pithampur SEZ belt): 436 paise/unit with fixed charges of ₹296-406/kVA by voltage level (MPERC MPIDC order, Jul 2025); non-industrial around 450-500 paise/unit. A FY 2026-27 retail order (PNo 140/2025) and a separate Pithampur SEZ tariff order (PNo 141/2025) have since been issued - verify current slabs against your connection agreement.

Note that MP's cheapest industrial power comes from DISCOM subsidised slabs; private OA/industrial HT consumers facing ₹7-8/kWh see the fastest solar paybacks.

Pithampur, Indore and the MP RE Policy 2025 green zones

MP's Renewable Energy Policy 2025 designates green zones - Pithampur, Mandideep, Dewas and the Indore SEZ - with cross-subsidy-surcharge relief (about ₹0.20/kWh saved), a seven-year electricity-duty exemption for renewable off-takers, land facilitation and single-window approvals; standard open-access charges of roughly ₹1.24/kWh drop to about ₹1.04/kWh inside the zones (market summary via MyR Solar, Mar 2026 - verify specifics against the policy text before committing). MP's open-access solar capacity grew 142% year on year in 2025, eighth among states (Mercom India, Mar 2026).

Industrial RPO obligations also bite: obligated entities in MP must meet 30% renewable share in FY 2025-26, rising to 36% in FY 2026-27 - rooftop solar counts toward compliance.

Application process

1. Submit the GIRES application (Annexure-2 to 5) at the DISCOM office or online portal with a ₹1,000 processing fee.
2. Connectivity approval, then execution of the metering connection agreement before generation begins.
3. Installation by an ALMM-listed vendor; DISCOM installs the bidirectional meter and commissions.

For systems above the state's CEIG threshold, electrical-inspector approval applies - see our CEIG guide. If your load exceeds 500 kW or you want surcharge-free supply beyond net metering, the open-access route is covered in our open access solar guide for India and the state open-access comparison.

Frequently Asked Questions

What is the net metering limit in Madhya Pradesh for industry?

500 kW per consumer (within contract demand/sanctioned load) under MPERC GIRES Regulations 2024. Systems above 500 kW can use gross metering up to 1 MW or the open-access route; GNM and VNM are available below 100 kW.

Is Madhya Pradesh good for industrial rooftop solar?

Yes - 300+ sunny days, yields of about 1,400-1,500 kWh/kWp, and HT industrial tariffs that make avoided costs ₹6-8/kWh for unsubsidised consumers. The 500 kW net metering cap and 80% transformer-headroom rule are the two binding constraints to check early.

What is the 80% transformer rule in MP?

GIRES 2024 caps cumulative renewable capacity at a distribution transformer at 80% of its rated capacity, and limits HT prosumers to 80% of their feeding transformer's rating. DISCOMs must publish transformer headroom annually - a saturated transformer can block your application even if your own load justifies the plant size.

Do net-metered solar prosumers pay wheeling or CSS in MP?

No. Net-metered (and gross-metered) prosumers are exempt from banking charges, wheeling charges, cross-subsidy surcharge and additional surcharge - but as a trade-off they cannot take open access with the same system. GNM and VNM beneficiaries do attract wheeling and surcharges.

What tariff does solar displace in Pithampur?

MPIDC-licensed Pithampur SEZ areas charge about ₹4.36/unit (HT, FY 2025-26) plus fixed charges of ₹296-406/kVA - among India's lower industrial tariffs, so solar paybacks there run longer than in the DISCOM areas where grid charges approach ₹7-8/kWh.
