Andhra Pradesh & Gujarat Power Discoms Expand Subsidized ₹1.50/Unit Aqua Power Slab to High-Density Commercial Farms

In a landmark regulatory reform for the Indian aquaculture sector, the Andhra Pradesh Electricity Regulatory Commission (APERC) and the Gujarat Electricity Regulatory Commission (GERC) have officially gazetted comprehensive amendments to their respective retail supply tariff orders. The revised regulations dismantle long-standing acreage and connected load caps that previously excluded medium and large-scale commercial aquaculture farmers from subsidized agricultural power slabs.

Under the previous tariff regime, the highly subsidized ₹1.50 per kilowatt-hour (kWh) agricultural aquaculture rate was strictly capped at smallholder farms operating under 5 acres with a maximum connected motor load of 10 Horsepower (HP). Any commercial farm exceeding these thresholds was automatically classified under expensive commercial and industrial (LT-III / HT-II) tariffs, paying between ₹6.50 and ₹7.80 per unit.

Recognizing that intensive modern shrimp culture (stocking 50 to 80 PL/m²) requires 30 to 45 HP of continuous paddlewheel aeration per hectare to sustain dissolved oxygen levels above 4.5 mg/L, the power commissions have harmonized power classifications. All Coastal Aquaculture Authority (CAA)-registered brackishwater and freshwater aquaculture holdings are now legally recognized under the subsidized agro-power category across Andhra Pradesh and coastal Gujarat.

The expanded tariff framework establishes clear, objective compliance rules to ensure subsidized power directly benefits bona fide commercial farmers while preventing unauthorized power diversion.

To qualify for the ₹1.50/kWh tariff slab, the aquaculture farm must hold an active, valid registration certificate issued by the Coastal Aquaculture Authority (CAA) under the Coastal Aquaculture Authority Act. For inland freshwater fish and scampi farms, a registration certificate issued by the State Department of Fisheries serves as valid authorization.

Under the amended orders, the connected load ceiling has been expanded up to 100 HP per service connection under the Low Tension (LT) Category V(B) tariff schedule. Farms requiring over 100 HP can now access dedicated High Tension (HT 11kV) agro-aquaculture connections at a subsidized base rate of ₹2.10/unit, saving hundreds of thousands of rupees annually on transformer transmission tariffs.

Tariff affordability is only half the battle; power continuity is a life-or-death operational necessity in intensive aquaculture. A 45-minute power outage during early morning hours in an intensive shrimp pond can trigger complete dissolved oxygen depletion, wiping out millions of rupees in standing crop biomass.

As part of the infrastructure upgrade, state distribution companies—APSPDCL (Southern AP), APEPDCL (Eastern AP), and DGVCL (South Gujarat)—have completed the segregation of dedicated 11kV aquaculture feeder corridors across the coastal belts of SPSR Nellore, Bapatla, Kakinada, Surat, and Navsari.

DISCOM operational guidelines now mandate a minimum of 20 to 22 hours of uninterrupted, balanced three-phase power supply on dedicated aqua-feeders. By eliminating frequent voltage fluctuations and daily brownouts, commercial farms can phase out their reliance on expensive diesel generators (which operate at ₹32 to ₹38 per kWh based on diesel @ ₹95/liter), delivering immediate operational cost savings of ₹1,20,000+ per month on a 10-acre farm.

In alignment with India's national renewable energy targets, the Ministry of New and Renewable Energy (MNRE) in partnership with state fisheries departments has unlocked Component C of the Pradhan Mantri Kisan Urja Suraksha evam Utthaan Mahabhiyan (PM-KUSUM) scheme for commercial aquaculture.

Under PM-KUSUM Component C (Feeder-Level & Individual Farm Solarization), aquaculture farmers can install grid-tied solar photovoltaic (PV) microgrid arrays to power their paddlewheel aerators, blowers, and water pumps. The central and state governments provide a combined 40% direct capital subsidy on total project CAPEX, with the remaining 60% financed through low-interest (7% with 3% subvention) Kisan Credit Card (KCC) loans from commercial banks.

Under net-metering regulations, solar electricity generated during sunny daytime hours directly powers farm aeration. Any surplus power generated between 11:00 AM and 3:00 PM is automatically exported back to the state power grid, earning power credits that offset nighttime grid consumption and reducing monthly electricity expenditures by an additional 55% to 70%.

Commercial aquaculture operators can migrate existing commercial power connections or apply for new subsidized connections through a simplified digital process:

1. Document Preparation: Collate digital copies of your valid CAA Farm Registration Certificate, Land Title Deed / Registered Lease Agreement (minimum 3-year term), electricity service connection number (USC No.), and Aadhaar card.

2. Online Portal Submission: Log into the state DISCOM digital portal (e.g., APSPDCL Spandana / APEPDCL Consumer Portal / DGVCL Solar Gateway) and navigate to 'Category Conversion to LT-V(B) Aquaculture' or 'New Agro-Aqua Service Connection'.

3. Field Verification: The local Assistant Divisional Engineer (ADE) and Village Fisheries Assistant (VFA) will conduct a joint physical inspection within 7 working days to verify connected motor horsepower, aeration grid layout, and meter calibration.

4. Tariff Activation: Upon ADE digital approval, the subsidized ₹1.50/unit billing rate is activated from the subsequent billing cycle.
