Renewable Energy — GST Framework

Solar Energy — 12% GST (Concessional)

SOLAR PANELS & MODULES: Solar PV modules (crystalline/thin film): 12% (HSN 8541). Solar cells (unassembled): 12%. Solar panel mounting structure: 18% (steel/aluminium — not concessional). Pre-October 2021: solar modules were 5%. October 2021: increased to 12% (to support domestic manufacturing under PLI scheme). WHY INCREASE FROM 5% TO 12%: Government logic: (1) India imports 80%+ solar modules from China. (2) At 5% GST: Chinese imports too cheap — kills domestic industry. (3) At 12%: slight cost increase but: BCD (Basic Customs Duty) on imports also added (25% on cells, 40% on modules). (4) Combined: domestic manufacturing becomes viable. Tata Solar, Adani Solar, Vikram Solar: supported. SOLAR EPC (Engineering, Procurement, Construction): Solar plant installation (EPC contract): COMPLEX. If supply of goods + installation = COMPOSITE SUPPLY. Tax: 12% (if solar panel is principal supply — goods > 70%). If predominantly service (design, engineering): 18%. Notification 11/2017: 'Composite supply of works contract as defined in section 2(119) for solar power plant': 12%. ROOFTOP SOLAR: Residential rooftop solar: 12% on panels + 18% on installation labor. Total effective rate: ~13-15% (blended). For homeowner: no ITC (residential = personal use). For commercial building: ITC available (business use). NET METERING: Excess solar power sold to DISCOM (grid): Power sale is EXEMPT from GST (electricity is exempt). But: solar equipment procurement: 12-18% (non-refundable for residential). SOLAR WATER HEATER: Solar water heater (domestic): 12% (HSN 8419). Solar cooker: 12%. Solar lantern: 12%. Solar pumps (agricultural): 12%. PM-KUSUM scheme: subsidized solar pumps — farmer bears 12% GST on their contribution. SOLAR INVERTERS & BATTERIES: Solar inverter (grid-tied): 12% (concessional rate). Solar battery (lead acid for solar): 18% (not concessional). Lithium battery for solar storage: 18%. Charge controller: 12%. Solar cables & connectors: 18%.

Wind Energy — 18% GST

WIND TURBINES & COMPONENTS: Wind turbine generator (WTG): 18% (HSN 8502). Wind turbine blades: 18%. Nacelle: 18%. Tower (steel): 18%. Gearbox: 18%. Yaw system: 18%. Control panel: 18%. WHY 18% (NOT 12% LIKE SOLAR): Wind industry is more mature than solar in India. India: 4th largest wind installed capacity (45+ GW). Companies (Suzlon, Inox Wind, Siemens Gamesa India): well-established. No need for concessional rate — industry can bear 18%. Solar needed 12% because: domestic manufacturing was non-existent. Wind: most components already manufactured in India. PRE-GST: Wind turbines had: 0% excise (exempt) + 5% VAT (some states). Post-GST at 18%: significant increase for wind industry. Industry protested: no rate reduction achieved. ITC BENEFIT: Wind projects: large capital investment (₹500-1000 crore per project). ITC on 18% = ₹90-180 crore recoverable. Against what output? Electricity sale is EXEMPT — so ITC is STRANDED. This is the BIGGEST issue for wind developers. STRANDED ITC — HOW DEVELOPERS COPE: (1) Sell power under OPEN ACCESS (B2B): power sold to industrial consumer at negotiated rate. Power sale: exempt. ITC on equipment: stuck (cannot offset against exempt output). (2) Request REFUND of ITC: Section 54(3) — refund of ITC on inputs for exempt supplies. But: proviso excludes 'nil rated and exempt goods' from refund. Wind power developers: CANNOT get ITC refund (electricity is exempt, not zero-rated). (3) Result: ITC becomes cost — added to project cost → increases per-unit cost of power. (4) Industry demand: either zero-rate electricity (allow refund) or reduce GST to 5% on wind equipment. Government: no change since 2017. WIND-SOLAR HYBRID: Hybrid projects (wind + solar): Solar portion: 12% on panels. Wind portion: 18% on turbine. Common infrastructure (substation, cables): 18%. Overall project: blended rate depending on component split.

Electric Vehicles & Batteries — 5% / 18%

ELECTRIC VEHICLES — 5% GST: Electric cars (BEV — Battery Electric): 5% (HSN 8703). Electric two-wheelers (e-scooter, e-bike): 5%. Electric three-wheelers (e-rickshaw): 5%. Electric buses: 12% (not 5% — different classification). Compare with ICE vehicles: Petrol/diesel cars (< 4m, < 1200cc): 28% + 1% cess = 29%. Petrol cars (> 4m or > 1200cc): 28% + 17-22% cess = 45-50%. Diesel SUV: 28% + 22% cess = 50%. EV at 5%: MASSIVE tax advantage (5% vs 29-50%). WHY 5% ON EVs: India's EV policy: accelerate adoption to reduce: oil imports (₹12-15 lakh crore/year), urban air pollution, and carbon emissions. 5% GST = one of lowest auto tax rates globally. Combined with FAME II subsidy + state subsidies: EVs becoming price-competitive. EV COMPONENTS — RATES: Lithium-ion batteries: 18% (HSN 8507). Lead acid batteries: 28% (for ICE vehicles) vs 18% (for EV use — separate entry). EV charger/charging station equipment: 18%. Charging cables: 18%. BMS (Battery Management System): 18%. Electric motor (for EV): 18%. BUT: ITC for EV manufacturer: Input (batteries, motors): 18%. Output (EV): 5%. INVERTED DUTY — manufacturer pays 18% on inputs, charges only 5% on output. ITC accumulation: significant. Refund: available under Section 54(3) (inverted duty refund). This is why: EV manufacturers (Tata, MG, Ola, Ather) claim regular ITC refunds. EV CHARGING SERVICE: EV charging station: charges customers for electricity + service. Classification dispute: If ELECTRICITY sale: exempt. If SERVICE (providing charging facility): 18%. Clarification (2019): EV charging = SUPPLY OF SERVICE: 18% GST. But: many argue it should be electricity sale (exempt). Current practice: most public chargers charge 18% GST. Home charging: electricity bill (exempt). BATTERY SWAPPING: Ola, Sun Mobility model: swap empty battery for charged one. Classification: supply of service (battery-as-a-service): 18%. If battery sold separately: 18% (goods). Swap subscription: 18% (service). Government considering: reduced rate for swapping (not implemented yet).

Biogas, Biomass & Biofuel — 5% / 12% / 18%

BIOGAS & BIO-CNG: Biogas (raw): 5% (HSN 2711). Bio-CNG (Compressed Biogas): 5%. CBG (Compressed Bio Gas — SATAT scheme): 5%. Biogas plant/digester: 12% (HSN 8405 — classified as gas generator). Biogas purification equipment: 18%. Bio-manure (byproduct of biogas): EXEMPT (organic manure). GOBAR-DHAN scheme: promotes biogas — equipment at 12% (concessional). BIOMASS: Biomass fuel (agri residue — rice husk, bagasse): EXEMPT (agricultural produce). Biomass pellets/briquettes: 5% (HSN 4401). Biomass power plant equipment: 18%. Biomass boiler: 18%. Combined Heat & Power (CHP): 18% on equipment. ETHANOL & BIOFUEL: Ethanol (for blending with petrol): 18% (denatured alcohol). But: ethanol used for fuel blending: effectively outside GST (petroleum products excluded). Biodiesel: 5% (HSN 3826). Bio-jet fuel (SAF — Sustainable Aviation Fuel): evolving (not fully classified). Ethanol for industrial use: 18%. Ethanol for potable alcohol: outside GST (state excise). WASTE-TO-ENERGY: Municipal solid waste (MSW) to energy: Plant equipment: 18%. Waste collection: 18% (service) or exempt (municipal service). RDF (Refuse Derived Fuel): 5%. Waste plastic to fuel (pyrolysis oil): 18%. Power generated: exempt (electricity). CNG from waste: 5%. CARBON CREDITS: Sale of carbon credits (CER/VER): Interesting: no specific GST classification. Industry practice: treated as 'intangible goods' — 18% GST. Some argue: carbon credit is neither goods nor service under GST Act. Recent: GST ruling in some states = 18% on carbon credit trading. International carbon markets: if exported = zero rated. HYDROGEN (GREEN): Green hydrogen: currently no specific GST rate (product too new). Equipment for electrolysis: 18%. Solar power for green hydrogen: 12% on panels. Water (input): exempt or 18% (depending on source). National Green Hydrogen Mission: ₹19,744 crore allocated. Expected: specific concessional GST rate (5-12%) to be announced.

Hydropower & Other Renewables — 18%

HYDROPOWER: Hydro turbine: 18% (HSN 8410). Generator: 18%. Penstock (pipe): 18%. Dam construction: 12% (works contract — immovable property for government). Transmission lines: 18%. Small hydro (< 25 MW): same rates as large. Micro hydro (< 100 kW): equipment 18%, some subsidized. POWER OUTPUT: Electricity from hydro: EXEMPT (all electricity is exempt from GST). ITC issue: same as wind — equipment at 18%, output exempt, ITC stranded. Hydro developers: same problem as wind developers. GEOTHERMAL: Geothermal plant equipment: 18%. Heat pumps: 18%. Very small sector in India — mostly Ladakh, Gujarat pilot projects. TIDAL/WAVE ENERGY: Ocean energy equipment: 18%. Very nascent in India — Gujarat/Tamil Nadu coastline exploration. No specific concessional rate (market too small for policy intervention). ENERGY STORAGE (Grid Scale): Lithium-ion BESS (Battery Energy Storage): 18%. Pumped hydro storage: 18% on equipment. Flywheel storage: 18%. Vanadium flow batteries: 18%. Sodium-ion batteries: 18%. Thermal storage: 18%. ALL storage: 18% — no concessional rate. Industry demand: reduce to 5% for grid-scale storage (critical for renewable integration). Government: 'under consideration' (no action taken). TRANSMISSION & DISTRIBUTION: HT cables for renewable parks: 18%. Transformers: 18%. Switchgear: 18%. SCADA systems: 18%. Smart meters: 18%. Green energy corridor (dedicated transmission for renewables): 18% on equipment. Solar park infrastructure (road, water, office): 18%. INVERTERS & POWER ELECTRONICS: Solar inverter: 12% (concessional). Wind inverter: 18% (no concession). Grid-tied inverter (generic): 18%. UPS/power backup: 18%. Voltage stabilizer: 18%. Energy meter: 18%.

Government Incentives & Policy Interface

RENEWABLE ENERGY + GST INCENTIVE MATRIX: (1) ACCELERATED DEPRECIATION: 40% AD on wind/solar assets. This is INCOME TAX benefit — independent of GST. GST paid on equipment: not affected by AD claim. Both can be availed simultaneously. (2) CUSTOMS DUTY EXEMPTION: Solar cells/modules: BCD 25% on cells, 40% on modules (April 2022). Before: 0% BCD (complete exemption to promote solar). Now: BCD imposed to support domestic manufacturing. Wind: most components have 5-7.5% BCD. (3) CONCESSIONAL GST vs REGULAR GST: Sector-wise rates: Solar panels: 12% (concessional, reduced from 18%). Solar inverters: 12%. Wind equipment: 18% (no concession). EV: 5% (most concessional). Biogas plants: 12%. All other renewable: 18% (standard). (4) PLI (Production Linked Incentive): Solar PLI: ₹24,000 crore for domestic module manufacturing. Battery PLI (ACC): ₹18,100 crore for battery gigafactories. Green hydrogen PLI: ₹17,490 crore. PLI benefit: independent of GST (it's a cash incentive based on sales). But: PLI manufacturer still charges 12-18% GST on output. (5) VIABILITY GAP FUNDING (VGF): Government pays VGF to make project viable. VGF receipt by developer: NOT subject to GST (it's a subsidy, not consideration for supply). But: equipment bought using VGF: GST applies normally (no exemption). (6) STATE INCENTIVES: Some states: SGST reimbursement on renewable equipment. Example: Gujarat reimburses SGST portion for solar manufacturing units. Andhra Pradesh: industrial incentive (electricity cost reimbursement, not GST). Tamil Nadu: capital subsidy (not GST related). (7) RPO (Renewable Purchase Obligation): Obligated entities must buy renewable power or RECs. REC trading: 18% GST (on trading service). Green certificates: 18% (intangible goods). (8) OPEN ACCESS: Third-party sale of renewable power: Power: exempt. Transmission charges: 18%. Cross-subsidy surcharge: outside GST (regulatory levy).

Frequently Asked Questions

Why is solar equipment at 12% but wind at 18% — isn't this unfair to wind energy?
SOLAR 12% vs WIND 18% — THE RATIONALE: HISTORICAL CONTEXT: 2017 (GST launch): Solar: 5%. Wind: 18%. 2021 (October): Solar increased to 12%. Wind: remained 18%. So the gap NARROWED (from 13% to 6%) — but not eliminated. WHY SOLAR GOT CONCESSIONAL RATE: (1) DOMESTIC MANUFACTURING GAP: In 2017: India had ZERO significant solar cell/module manufacturing. 95%+ imported from China. 5% GST = cheap imports = fast solar deployment. Government priority was INSTALLATION first, manufacturing later. Wind: India already had Suzlon, Inox Wind, Siemens Gamesa India. 60%+ components domestically manufactured. No need to subsidize imports. (2) NATIONAL SOLAR MISSION: Target: 500 GW renewable by 2030 (280 GW solar). Solar needed aggressive cost reduction. 5% GST (later 12%) helps: reduces project cost. Feeds into lower tariff bids (solar tariffs: ₹2-3/unit — among world's cheapest). Wind: already mature — tariffs settled at ₹2.5-3.5/unit. (3) EMPLOYMENT vs AUTOMATION: Solar installation: labor-intensive (millions of rooftop jobs). Lower GST → more installations → more jobs. Wind: capital-intensive (fewer jobs per MW). Less social pressure for concessional rates. WHY WIND INDUSTRY IS UPSET: (1) Unfair competition: solar + wind compete for same PPAs (Power Purchase Agreements). Solar at 12% GST: lower capital cost → lower tariff bid. Wind at 18% GST: higher capital cost → higher tariff bid. Result: solar wins most auctions. (2) ITC stranding: wind at 18% = more ITC stuck (output electricity is exempt). Solar at 12% = less ITC stuck (lower input tax). (3) Industry decline: Indian wind additions dropping (from 5-6 GW/year to 2-3 GW/year). Multiple reasons (land, policy, grid) — but GST disparity is one factor. WIND INDUSTRY'S DEMAND: Reduce wind GST to 12% (parity with solar). OR: allow ITC refund for power generators (treat electricity as zero-rated, not exempt). Government response: 'under review' for 7+ years. No change implemented. GST Council position: revenue considerations prevent reduction.
How does the ITC stranding problem work for renewable energy developers — and is there any solution?
ITC STRANDING IN RENEWABLE ENERGY — THE CORE PROBLEM: THE MECHANISM: Developer buys equipment: pays 12-18% GST (input tax credit). Developer generates electricity: sells at 0% (electricity exempt from GST). Developer's ITC: CANNOT be offset against output (no output tax). ITC becomes COST: added to project economics. SCALE OF THE PROBLEM: 1 GW Solar project: Cost: ~₹4,000-5,000 crore. GST on equipment (12%): ₹480-600 crore. This ITC: completely stranded. Absorbed in project cost → increases per-unit generation cost by ₹0.20-0.30/kWh. For 500 GW national target: ₹2-3 lakh crore of stranded ITC across the sector. 1 GW Wind project: Cost: ~₹6,000-7,000 crore. GST on equipment (18%): ₹1,080-1,260 crore stranded. Even worse for wind (higher rate + higher cost). ATTEMPTED SOLUTIONS (ALL FAILED): (1) Treat electricity as 'zero rated' instead of 'exempt': If zero rated: ITC refund possible (like exports). But: electricity is CONSTITUTIONALLY under state list. States collect electricity duty. Moving to GST: states lose revenue. Political impossibility — states will NEVER agree. (2) Reduce GST to 5% on ALL renewable equipment: Reduces stranding (5% stuck vs 18%). But: government loses revenue + domestic manufacturers lose protection. (3) Allow ITC refund even for exempt output: Requires law change (Section 17(2) specifically blocks this). No indication of amendment. (4) GST exemption for RE equipment: Revenue loss: ₹15,000-20,000 crore annually. Political will: absent. WHAT DEVELOPERS ACTUALLY DO: (a) Include GST cost in project viability calculation. (b) Bid higher tariff to recover GST cost (but this makes bids uncompetitive). (c) Negotiate with DISCOM: sometimes GST pass-through allowed in PPA. (d) Use 70:30 debt structure: debt portion helps amortize GST cost. (e) Some developers: set up separate trading entity to create taxable output (complex structuring). THE REAL IMPACT: India's renewable tariffs would be 5-8% LOWER if ITC issue resolved. ₹2.50/unit solar could become ₹2.30/unit — making India's renewables even more globally competitive. The ITC problem is India-specific: most countries either exempt RE equipment from VAT/GST or allow refunds for power generators.
What's the GST situation for residential rooftop solar — and can homeowners claim any benefit?
RESIDENTIAL ROOFTOP SOLAR — GST FOR HOMEOWNERS: WHAT HOMEOWNER PAYS: Solar panel (3-10 kW system): 12% GST. Inverter: 12% GST. Mounting structure: 18% GST. Wiring, cables, connectors: 18% GST. Installation labor (if separate): 18% GST. Net meter: 18% GST (provided by DISCOM usually). TOTAL EFFECTIVE GST: On ₹3-6 lakh system cost: approximately 13-15% blended rate. GST amount: ₹39,000-90,000 depending on system size. CAN HOMEOWNER CLAIM ITC?: NO — residential consumption is PERSONAL use. GST law: ITC available only for business purposes. Homeowner installing rooftop solar: no ITC claim possible. The 12-15% GST: permanent cost for homeowner. IF HOMEOWNER SELLS EXCESS POWER: Net metering: excess power exported to grid. Payment by DISCOM: for units exported. GST on power sale: EXEMPT (electricity is exempt). So homeowner: pays GST on purchase (12-15%), gets nothing back. Sells power: no GST implication (exempt output). BUSINESS vs RESIDENTIAL: Company installing rooftop solar on factory: ITC AVAILABLE. Can offset GST on solar equipment against: GST on goods manufactured, GST on services provided. Effective solar cost: lower by 12-18% for businesses (ITC benefit). This creates DISPARITY: Business solar: effectively 0% GST (full ITC). Residential solar: 12-15% GST (no ITC). Result: commercial/industrial solar adoption faster than residential. SUBSIDY INTERACTION: PM Surya Ghar (free electricity scheme): Government subsidy: ₹30,000-78,000 per household. Subsidy DOES NOT cover GST portion. Homeowner: pays ₹3-6 lakh system cost. Gets: ₹30,000-78,000 subsidy (central) + state subsidy (varies). Net cost after subsidy: ₹2-5 lakh. GST on ₹2-5 lakh: ₹26,000-75,000. This GST: not subsidized, not refundable. WHAT WOULD HELP HOMEOWNERS: (1) Reduce residential solar to 5% (like EV): would save ₹15,000-45,000 per installation. (2) GST exemption for rooftop solar (up to 10 kW): complete relief. (3) Subsidy covering GST: government absorbs GST cost. None of these are currently planned. Government stance: 12% is already concessional (standard rate is 18%).
How is GST applied to Electric Vehicle charging — is it electricity (exempt) or service (18%)?
EV CHARGING — THE CLASSIFICATION CONTROVERSY: THE QUESTION: When you charge your EV at a public charging station: Are you BUYING ELECTRICITY (exempt from GST)? OR are you PAYING FOR A SERVICE (18% GST)? GOVERNMENT'S ANSWER (2019 CLARIFICATION): EV charging = SUPPLY OF SERVICE (not supply of goods/electricity). SAC: 998714 (Electricity distribution services). Rate: 18% GST. Logic: Charging station provides a SERVICE (use of infrastructure, equipment, parking space, maintenance). They don't sell electricity as a commodity. WHY NOT 'ELECTRICITY SALE'?: (1) Legal: Charging stations don't have electricity DISTRIBUTION license. Only DISCOMs (BSES, Tata Power, etc.) can sell electricity. Charging stations: buy electricity from DISCOM → provide charging service. (2) Value addition: station provides: equipment, connectors, software, space, maintenance. This is more than mere electricity resale. (3) Comparison: Petrol pump sells petrol (goods — outside GST). But: battery charging = service (not a tangible good being transferred). Analogy: hotel charging your phone: it's accommodation service, not electricity sale. IMPACT ON EV ADOPTION: PETROL/DIESEL: effectively 50-60% taxed (excise + VAT — outside GST). CNG: 5% GST (composite supply). EV CHARGING: 18% GST. Per-km running cost comparison: Petrol car: ₹8-10/km (including fuel tax). EV (home charging): ₹0.8-1.2/km (electricity exempt). EV (public charging): ₹1.5-2.5/km (including 18% GST on charging). Home charging: cheapest (no GST on domestic electricity). Public charging: more expensive due to 18% GST + operator margin. This creates: incentive for HOME charging, disincentive for PUBLIC charging. Problem: India needs public charging INFRASTRUCTURE for EV adoption. 18% GST on public charging = barrier. INDUSTRY DEMAND: Reduce EV charging to 5% (same as EV vehicle). Logic: if EV at 5%, why is charging at 18%? Charging is ESSENTIAL to EV use — should be at same concessional rate. International comparison: UK: 5% VAT on EV charging (reduced rate). EU: varies 5-21% (many countries have reduced rates). India at 18%: among highest in world for EV charging. BATTERY SWAPPING: Swap station (Ola, Sun Mobility): provides charged battery, takes empty. Classification: SUPPLY OF SERVICE (battery rental/swap): 18%. Battery purchase (if buying outright): 18% (goods). Swap subscription fee: 18%. Same 18% problem as charging. WORKAROUND USED: Some charging networks: bundle charging with parking (parking is exempt in some cases). Or: membership model (annual fee + per-unit cost — service element at 18%). Fast charging premium: 18% on entire amount (no split billing). Home charging solution: buy electricity from DISCOM (exempt) → charge EV. Zero GST. This is why: 85%+ EV charging happens at HOME in India.
