Frequently Asked Questions

Which is better for industrial solar — Vijayawada or Vizag?

The bottom line: both are tier-1 AP industrial cities with the same policy framework (AP Solar Energy Policy 2024-29). The answer depends on operational profile: Vizag for steel + refinery + pharma SEZ + port-heavy industrial concentration; Vijayawada for Amaravati admin + Krishnapatnam Port + Auto Nagar + Mangalagiri food/textile. For multi-city AP operations, deploy across both with shared EPC partner.

What's the cost difference between Vijayawada and Vizag solar?

Solar capex is essentially identical: 1 MW industrial rooftop EPC costs ₹3.45-3.95 Cr in Vijayawada, ₹3.55-4.05 Cr in Vizag. The marginal difference reflects Vizag's slightly more industrial-heavy profile requiring more specialty engineering (Ex-zone for HPCL refinery, etc.).

Do both cities require coastal salt engineering?

Yes. Vijayawada's Krishnapatnam Port-adjacent sites require coastal salt + cyclone engineering. Vizag is on the AP coast and fully requires double-coated HDG/aluminium structures + IP66 enclosures + tinned copper. The engineering premium of 5-7% over inland AP applies to both.

Can group captive open access work for both cities?

Yes. AP's flagship Anantapur and Kurnool solar parks (3,000+ MW combined capacity) deliver group captive open access at ₹3.20-3.65/kWh landed cost. Anantapur is 450-700 km from both cities; Kurnool is 300-650 km. AP's 50% cross-subsidy waiver for 5 years on open access applies. See our open access solar India guide.

Should multi-state AP industrial groups standardise EPC partner across both cities?

Yes. Sun Wave's multi-city AP coordination delivers (a) consistent SLD/BoM/EMS, (b) shared O&M routing across Visakhapatnam + Vijayawada + Sri City + Chittoor, (c) consolidated reporting for ESG cascade, (d) bulk procurement leverage on modules and inverters, (e) federation-level monitoring dashboard.

How does AP's 7-year electricity duty exemption work?

AP Solar Energy Policy 2024-29 exempts captive solar consumption from electricity duty for 7 years from COD. This translates to ₹0.55-0.70/kWh of avoided duty on industrial tariffs over the exemption decade. For a 1 MW project consuming 1,400 MWh/year, the 7-year exemption captures ₹55-70 lakh of additional savings beyond standard arbitrage. Among India's longest such exemptions (tied with Himachal Pradesh at 7 years; Uttarakhand at 10 years).

Should Vizag refinery / Vijayawada port operations include BESS?

Voluntary in AP. However, BESS is operationally valuable for (a) cyclone-season grid resilience for coastal sites, (b) Time-of-Day arbitrage, (c) refinery process continuity in Vizag, (d) port operations continuity in both cities. A 500 kWh / 2-hour LFP battery for 1 MW solar adds ₹55-65 lakh capex but delivers ₹4-7 lakh/year combined value. See our DG vs BESS comparison.

Financial Model: 1 MW Industrial Solar in Both Cities

Understanding the full financial picture helps industrial buyers compare both cities on equal terms. Here is a representative financial model for a 1 MW rooftop captive solar project at an industrial facility in either city:

Capital Cost Breakdown (1 MW CAPEX, FY2026 Pricing)

The Vizag premium reflects coastal engineering requirements specific to refinery and port adjacency — higher wind load specifications, salt spray corrosion treatment, and occasional Ex-zone (explosion-proof) electrical requirements near HPCL operations.

Annual Energy Generation Estimate

Both cities receive 1,540-1,640 kWh per kWp annually (based on Global Solar Atlas and local irradiation data). For a 1 MW system:

• Annual generation: 1,400-1,600 MWh (accounting for system losses, shading, degradation year 1)
• Self-consumption rate: typically 80-95% for daytime-heavy industrial loads
• Grid banking: surplus units banked with APSPDCL/APEPDCL, redeemed in morning/evening peak hours

Savings Calculation (₹ per year)

At HT-I tariffs of approximately ₹8.20-9.50/kWh:

• Annual avoided electricity cost: ₹1.15-1.52 Cr (at 1,400-1,600 MWh generation x ₹8.20-9.50)
• Electricity duty savings (7-year exemption): ₹7-10 lakh/year additionally
• Payback period: 3.6-4.4 years (CAPEX basis)
• Project IRR (25 years): 25-29%
• LCOE (Levelised Cost of Energy): ₹1.60-2.20/kWh over 25 years

These figures make industrial solar in both Vijayawada and Vizag among the most attractive investment cases in southern India.

RESCO/OPEX Option: Zero Investment Solar for Both Cities

For industrial facilities that prefer to avoid capital outlay, RESCO (Renewable Energy Service Company) or OPEX solar is available in both cities. Under this model:

• The solar developer (like Sun Wave Technologies) installs, owns, and maintains the solar plant
• The industrial buyer pays only for units consumed at a fixed tariff, typically ₹4.50-5.80/kWh
• Contracted period: 15-25 years
• No capital investment, no O&M responsibility, immediate savings from day one

RESCO vs CAPEX Decision Framework for AP Industrial Buyers

For AP industrial buyers with owned premises and taxable profits above ₹1 Cr/year, the CAPEX model typically delivers higher total value. See our detailed RESCO vs CAPEX vs Open Access comparison for a full decision framework.

Sector-Specific Solar ROI: Vijayawada vs Vizag

Pharma and Chemical Industries

Vizag hosts the Atchutapuram Pharma SEZ — Aurobindo Pharma, Divi's Laboratories, Hetero Drugs, Mylan, and Eisai all have large campuses there. Pharma manufacturing is typically a 24/7 load profile with high energy intensity. Solar ROI is maximized for:

• Daytime utility during clean-room energy-intensive operations
• BESS integration for critical power continuity
• Open access from Anantapur/Kurnool for base load supplement

Vijayawada's Kondapalli industrial cluster has API (active pharmaceutical ingredient) units. Smaller scale than Vizag, but the same financial model applies.

Steel and Heavy Industry

Vizag is dominated by RINL (Rashtriya Ispat Nigam Limited) Visakhapatnam Steel Plant with 7.3 MTPA capacity. Steel plants have enormous captive solar potential (80-150 MW for a major plant), but captive solar competes with the plant's internal power grid. For large steel EPC solar projects, the structured approach involves:

• Dedicated substations for solar integration
• Anti-islanding protection per CEA guidelines
• SCADA integration with plant DCS

Vijayawada's Auto Nagar has engineering and auto component units (typically 200 kW-3 MW scale) with daytime-dominated load profiles ideal for solar ROI.

Food Processing and FMCG

Vijayawada-Mangalagiri hosts rice mills, food processing, and FMCG operations — daytime heavy manufacturing with seasonal production variation. Solar combined with cold storage units in this belt delivers among the strongest ROI cases in AP. See our food processing solar guide.

O&M Considerations: Long-Term Operations in Coastal AP Cities

Both cities require specialized O&M protocols due to coastal conditions. Industrial buyers should ensure their EPC contract or O&M agreement includes:

Preventive Maintenance Schedule (12-Month)

Cyclone season (April-May and October-November) requires pre-cyclone checks in both cities. Vizag sits in the path of Bay of Bengal cyclones and has historically received Cyclone Hudhud-scale events; module mounting at 50-55 m/s wind speed per IS-875 Part 3 is mandatory.

Performance Benchmarks for AP Coastal Projects

A well-maintained 1 MW system in Vijayawada or Vizag should achieve:

• Performance Ratio (PR): 79-84% annually
• Specific Yield: 1,540-1,640 kWh/kWp
• Availability: 98%+ (excluding grid outages)
• Degradation rate: 0.5-0.7% per year (Tier-1 TOPCon modules)

For comprehensive O&M guidance, see our solar O&M guide for India.

How to Choose Between Vijayawada and Vizag

For industrial buyers with operations in both cities — or choosing between them for a new facility — here is the decision framework:

1. Assess your load profile: Is it daytime-heavy (solar maximizes value) or 24/7 (consider open access + BESS)?
2. Check your tenancy: Owner-occupier = CAPEX; lessee = RESCO/OPEX
3. Verify your DG set running hours: High DG hours = faster solar payback and clear economic driver
4. Assess coastal exposure: Refinery/port proximity in Vizag requires stricter engineering specs
5. Check AP DISCOM connection strength: HT connection above 500 kW enables net metering; above 1 MW enables wheeling/open access
6. Review the AP Solar Energy Policy 2024-29 benefits: Both cities access the same benefits — 7-year ED exemption, 50% cross-subsidy waiver for 5 years, banking at 5%
