Section 01
Executive Summary
NextCharge TH3ERV is an independent public EV fast charging operator being established in Tamil Nadu, India, under the TH3ERV group of companies. The company will deploy 3 × 50 kW DC fast chargers integrated with a 20 kW rooftop solar system, targeting urban Chennai and strategic highway corridors where EV adoption is high and public charging infrastructure is critically undersupplied.
Tamil Nadu is India's fourth-largest EV market, with 1.37 lakh units sold in FY2025, yet has only 1,781 public charging stations — a ratio of 1 charger per 316 registered EVs against a healthy benchmark of 1:20. The state has set a target of 24,715 stations by 2030, representing a 14× growth requirement that cannot be met by government investment alone. This gap is the commercial opportunity.
The business is structured as an independent CPO (Charging Point Operator) under a Private Limited Company with MSME registration. Financing is through a bank term loan (60% of net CAPEX, ₹15–20L) from SBI under the EV Mitra scheme, with founder equity covering the remaining 40%. No outside equity is required.
Investment case in brief: Gross CAPEX of ₹52–60L is reduced to ₹18–26L net after combined subsidies of ₹34–42L from TN EV Policy 2023, PM E-DRIVE, and MNRE solar CFA. The station is EBITDA-positive from Month 1 at 30% utilisation, with a payback period of 3–4 years and projected 5-year cumulative cash flow of ₹80–110L.

Tamil Nadu EV Market Overview
Tamil Nadu has emerged as one of India's most active EV manufacturing and adoption states. The state hosts major EV manufacturers including Ola Electric, Ather Energy, TVS Motor, Hyundai (Ioniq 5), VinFast, and major battery component suppliers. FY2025 saw 1.37 lakh EV units sold in Tamil Nadu, ranking it 4th nationally.
The state government has committed to a ₹50,000 crore EV investment target and has designated six cities as EV priority zones: Chennai, Coimbatore, Madurai, Salem, Tiruchirappalli, and Tirunelveli. The Tamil Nadu EV Policy 2023 provides a comprehensive incentive framework covering capital subsidies, electricity tariff concessions, and interest subventions specifically for EV charging infrastructure operators.
| City | e-4W Sales Share | Public Chargers (est.) | Charger Gap | Priority Tier |
|---|
| Chennai | 41.2% | ~800 | High — urban zones empty | Tier 1 |
| Coimbatore | 13.7% | ~150 | High — city centre underserved | Tier 1 |
| Tiruppur | 8.3% | ~40 | Critical — textile fleet converting | Tier 2 |
| Madurai | 6.6% | ~60 | High — BMW corridor node | Tier 2 |
| Salem | 4.1% | ~30 | Critical — almost none | Tier 2 |
| Hosur (Krishnagiri) | High (2W/3W mfg) | ~100 (TVS-owned) | Moderate — OEM-dominated | Tier 1 |
The India EV charging market is growing at a CAGR of 27.7%, expanding from $487M to a projected $1.65B by 2030. Tamil Nadu, with its combination of manufacturing scale, government policy support, and a 14× charger growth gap, represents one of the highest-opportunity state markets for independent CPO entry in 2026.
Critical market insight: 90% of Tamil Nadu's public chargers are located within 1 km of a national or state highway. This means urban residential zones, IT parks, industrial estates, and Tier-2 city centres are almost entirely without public fast charging — the exact locations where EV ownership is growing fastest.
Section 03
Industry Players & Competitive Landscape
The Tamil Nadu EV charging market is served by a mix of national franchise CPOs, OEM-linked networks, government entities, and a small number of independent operators. Understanding each player's model helps frame NextCharge TH3ERV's positioning as an independent with full margin ownership and subsidy control.
| Player | Network Size | Model | TN Presence | Partnership Available |
|---|
| Tata Power EZ Charge | 5,500+ points | DOCO franchise — you invest, they operate, revenue shared 65/35 | Growing in Chennai, highways | Yes — franchise application |
| ChargeZone | 15,000+ points | DOCO — DOCO supercharging focus, 500kW–1.5MW highway hubs | NH-48, NH-16 active | Yes — franchise + SBI EV Mitra |
| Statiq | 8,000+ points | FOCO / outright purchase / white-label CMS | BMW corridor: CBE, Madurai | Yes — FOCO or outright |
| Jio-bp Pulse | 5,000+ points | Petrol pump co-location, Reliance-BP JV | Limited in TN | Via HPCL/BPCL partnership |
| Ather Grid | 2,000+ points | OEM-linked, open to public | Chennai, Coimbatore, Hosur | Limited — OEM-first |
| TNGECL (Govt.) | 500 (target) | PPP — government deploys, private operates | State-wide rollout in progress | PPP tender participation |
| Delta Electronics India | Manufacturer | Charger OEM + deployment support (Krishnagiri plant) | Manufacturing in TN | Buy direct — best local support |
| ThunderPlus | 2W/3W specialist | Fast charger network for 2-wheelers + 3-wheelers | Growing in TN cities | Equipment partnership |
| Magenta ChargeGrid | Solar-integrated | Rooftop solar + EV charging combined | South India expansion | Solar + charger package |
NextCharge TH3ERV's competitive advantage: As an independent operator, the company retains 100% of charging revenue (vs 35% given to Tata Power), claims all subsidies directly, sets its own tariffs (enabling fleet pricing), and can integrate solar without CPO partner approval. The trade-off is higher operational responsibility — mitigated by using OCPI-enabled CMS software (Pulse Energy or Kazam) for remote monitoring and support.
Section 04
Investment & Policy Landscape
Tamil Nadu offers one of the most comprehensive policy stacks for EV charging infrastructure in India as of 2026. The combination of state and central government incentives can recover ₹34–42L of the total ₹52–60L project cost — a 58–70% subsidy coverage ratio that is exceptionally high for an infrastructure investment of this type.
| Scheme | Authority | Benefit | Amount (this project) | Application route |
|---|
| TN EV Policy 2023 — Capital subsidy | GUIDANCE Tamil Nadu | 25% of equipment cost, capped ₹10L per DC fast charger. First 200 stations only. | Up to ₹30L | investingintamilnadu.com |
| MNRE — PM Surya Ghar solar CFA | Ministry of New & Renewable Energy | 40% capital subsidy on rooftop solar system cost | ~₹4L | pmsuryaghar.gov.in |
| PM E-DRIVE — Upstream infra | Ministry of Heavy Industries / BHEL | 50–100% of HT line + transformer upgrade cost (Category A city) | ₹2–5L | pmedrive.heavyindustries.gov.in |
| TN electricity demand relief | TANGEDCO / TN Govt | 75% demand charge cut Yr 1–2; 50% Yr 3–4 | ₹3–4L/yr saved | With HT connection application |
| TN interest subvention | Tamil Nadu Govt / lending bank | 5% interest rebate on term loan for 6 years | ₹4.5L over 6 years | At loan sanction |
| SBI EV Mitra scheme | State Bank of India | Green term loan for EV infrastructure — ₹10L to ₹10Cr, up to 7 years, CGTMSE guarantee | ₹15–20L at ~7% effective | Nearest SBI branch / SBI green finance desk |
Time sensitivity: The TN EV Policy 2023 capital subsidy is capped at the first 200 public fast charging stations. This cap is actively filling in 2025–26 as multiple CPOs expand in the state. Late applications may receive reduced or no capital subsidy. PM E-DRIVE's ₹2,000 crore national budget is similarly first-come, first-served.
Section 05

5-Year Projection Summary
| Year | Utilisation | Revenue | EBITDA | EBITDA Margin | Net Cash Flow | Cumulative CF |
|---|
| Year 1 | 30% | ₹37.9L | ₹20L | 52.8% | ₹10.7L | ₹10.7L |
| Year 2 | 42% | ₹53L | ₹28.5L | 53.8% | ₹16.8L | ₹27.5L |
| Year 3 | 55% | ₹69.5L | ₹37.8L | 54.4% | ₹23.1L | ₹50.6L |
| Year 4 | 65% | ₹82.2L | ₹45.2L | 55% | ₹27.9L | ₹78.5L |
| Year 5 | 72% | ₹91.1L | ₹50.4L | 55.3% | ₹31.2L | ₹109.7L |
Payback analysis: At base-case assumptions, the net CAPEX of ₹25.25L is recovered within 28–34 months of commissioning (2.3–2.8 years from cash flow start). The investment fully pays back including debt service within 3.5–4 years. From Year 4 onwards, the station generates approximately ₹25–30L/year in net free cash flow.
Section 06
Location Strategy
Site selection is the single most consequential decision in the EV charging business. A poorly located station with excellent chargers will fail. An average charger in the right location will succeed. The following framework drives site evaluation.
Site scoring criteria
| Criterion | Weight | Threshold for viability |
|---|
| EV density in 3 km radius | 25% | Minimum 500 registered EVs. Check VAHAN dashboard by RTO code. |
| TANGEDCO transformer proximity | 20% | Within 200m of an HT transformer with ≥150 kVA spare capacity. Farther = ₹3–8L extra CAPEX. |
| Fleet anchor potential | 20% | At least one logistics/e-commerce/taxi operator within 3 km with active EV fleet electrification. |
| Dwell time of typical visitor | 15% | Minimum 25–30 minutes at the venue (restaurant, mall, hospital, IT park). This is how long DC fast charging takes.
| Nearest competitor charger | 10% | Nearest public DC fast charger >1.5 km away. Check e-AMRIT map (niti.gov.in).
| Road visibility and access | 5% | Visible from main road within 200m. Easy entry/exit for 4-wheelers.
| Solar potential | 5% | South-facing roof or canopy with ≥1,000 sq ft unshaded area between 9am–3pm.
Priority site categories for NextCharge TH3ERV
| Site type | Utilisation potential | Lease cost | Recommended model |
|---|
| IT park / tech campus (OMR) | Very high | Medium–high | 3 DC + AC workplace mix. Long-term facility MoU. |
| Industrial estate (Ambattur, Sriperumbudur) | Very high | Medium | Fleet hub. Pre-sign logistics/delivery company contract. |
| Mall / retail complex | High | High | 3 DC fast. 20–40 min dwell aligns perfectly. |
| Petrol pump co-location | Medium–high | Low | Fast to open. HT connection often existing. |
| Highway (NH-48, NH-44) | Medium | Low | 4 chargers, higher kWh/session. Petrol pump preferred partner. |
| Hotel / resort (ECR, city hotels) | Medium | Low–medium | Overnight AC + DC fast combo. Premium customer base. |
Section 07
Regulatory & Compliance Framework
No special licence is required to operate a public EV charging station in India. CPOs operate as standard commercial entities. However, several technical standards and regulatory requirements must be met before commissioning.
| Requirement | Authority | Details |
|---|
| Company registration | Ministry of Corporate Affairs | Private Limited Company via SPICe+ form. PAN, TAN, GST auto-linked. |
| MSME Udyam registration | Ministry of MSME | 10 minutes online. NIC code 35202. Mandatory for TN additional subsidy (20% extra). |
| GST registration | CBIC | SAC code 996921. 5% GST on EV charging services (not 18%). Critical for correct billing. |
| Charger technical standards | Bureau of Energy Efficiency (BEE) | BEE star-rating mandatory. CCS2 connector for DC fast (4-wheelers). OCPP 1.6J or 2.0.1 protocol. |
| TANGEDCO HT connection | TANGEDCO | 150 kVA HT commercial (HT-III category). Form A application + AE inspection + EIG certificate. |
| Electrical Inspector clearance | EIG, Tamil Nadu | Mandatory before TANGEDCO meter installation. Inspects HT panel, earthing, cable sizing. |
| Solar net meter | TANGEDCO | Form B application for grid-connected rooftop solar. Required for MNRE CFA claim. |
| Tamil Nadu Public Charging Guidelines | TN Government (July 2025) | India's first state-level EV charging framework. Covers technical standards, agency roles, and approvals. |
TANGEDCO timeline note: New HT commercial connections in Chennai take 60–90 days from application to energisation under normal circumstances. If a transformer upgrade is required, add 4–6 weeks. Starting the TANGEDCO application immediately upon lease signing is the single most important action to protect your 22-week launch timeline.
Section 08
Risk Analysis & Mitigants
The EV charging station business carries manageable risks at the scale of this project. The main risks are operational and market-timing in nature, not structural — the demand fundamentals (EV adoption, regulatory push, subsidy availability) are firmly in place.
Low utilisation in first 12 months
Risk: Public EV fleet in target zone is still thin in Year 1, leading to below-30% utilisation and cash flow pressure.
Mitigant: Pre-signing one fleet contract (e-commerce, logistics, or taxi fleet) before opening guarantees 15–25% base utilisation from Day 1. The station is EBITDA-positive even at 20% utilisation with solar cost advantage.
TANGEDCO delay extending timeline
Risk: HT connection takes 120+ days instead of 60–90, delaying launch and incurring lease costs without revenue.
Mitigant: File HT application on the same day the lease is signed. Do not wait for subsidy approval before filing with TANGEDCO. If transformer upgrade is needed, negotiate cost into the CAPEX budget before signing the lease.
Subsidy cap filled before application processed
Risk: TN Policy 2023 first-200-station cap is reached before GUIDANCE processes the application, reducing subsidy from ₹30L to near zero.
Mitigant: File with GUIDANCE portal on Week 4 of the project (immediately after incorporation). The subsidy is allocated by application date, not approval date. Simultaneously file PM E-DRIVE to reduce dependence on TN subsidy alone.
TANGEDCO electricity cost increase
Risk: TANGEDCO revises HT commercial tariffs upward, compressing margins. Fixed demand charges are already ₹304/kVA/month (July 2025).
Mitigant: The 20 kW solar system structurally hedges against energy cost increases. After Year 4, the demand charge relief expires — review tariff and consider adding battery storage (BESS) to shift peak load at that stage.
Competition from franchise CPO expansion
Risk: Tata Power or ChargeZone opens a station within 1 km of the chosen site, splitting utilisation.
Mitigant: Select sites with a fleet anchor contract (a competitor cannot easily displace a contracted fleet customer). Urban zones with IT park or industrial estate MoUs create captive revenue that public competition cannot easily erode.
Charger equipment failure / downtime
Risk: DC fast charger failure creates revenue loss (estimated ₹4,000–6,000/day per down charger).
Mitigant: Comprehensive 3-year AMC from charger vendor (Delta/Exicom) with 4-hour response SLA in Chennai. OCPP CMS remote monitoring alerts before critical failures. 3 chargers provide redundancy — revenue impact of one failure is 33%, not 100%.
Section 09
Go-to-Market Plan — 22-Week Timeline
The 22-week execution plan is structured to run multiple workstreams in parallel, with TANGEDCO HT connection as the critical path item that governs the overall timeline.
| Phase | Weeks | Key actions | Critical outputs |

| Phase 6 — Launch | Wk 16–22 | Google Maps, PlugShare, e-AMRIT listings, OCPI roaming enabled, tariff structure set, staff hired + NSDC EV training, AMC contract signed, fleet contract activated, opening-day marketing, 90-day utilisation blitz | Station live, fleet revenue from Day 1, discovery across all CPO apps |
First 90 days utilisation targets
| Month | Target utilisation | Key action |
|---|
| Month 1 | 20–25% | Fleet contract active from Day 1. Walk-in public traffic building via OCPI discovery apps. |
| Month 2 | 25–30% | Second fleet operator onboarded. Google Maps reviews accumulating. Time-of-day pricing adjusted based on peak patterns. |
| Month 3 | 30–35% | First TANGEDCO bill reviewed. MNRE solar output verified. TN subsidy second tranche (post-commissioning) filed. Revenue model validated. |
Section 11
Investment Case Summary
NextCharge TH3ERV is a capital-efficient, subsidy-backed infrastructure play in one of India's fastest-growing EV markets. The investment case rests on five pillars:
| Pillar | Evidence |
|---|
| Structural demand gap | 1 charger per 316 EVs in Tamil Nadu vs benchmark of 1:20. A 14× growth gap cannot be bridged without private operators entering the market at scale. |
| Government co-investment | ₹34–42L in combined subsidies from TN, central government, and MNRE — representing 58–70% of total project cost. The government is already financially committed to this sector. |
| Capital-efficient structure | Net CAPEX of ₹18–26L after subsidies. 60% financed via SBI bank loan at ~7% effective rate. Founder equity of ₹10–14L only. No outside equity required. |
| EBITDA-positive from Month 1 | At 30% utilisation — achievable with a single fleet contract before opening — the station covers all operating costs and generates positive monthly EBITDA. This is not a speculative bet on future utilisation. |
| First-mover subsidy advantage | TN EV Policy 2023 caps subsidies at first 200 fast charging stations. Every month of delay reduces the probability of full subsidy capture. Early movers capture a competitive cost advantage that later entrants cannot replicate. |
This report has been prepared by the founders of NextCharge TH3ERV for the purpose of bank loan applications, subsidy filings, and investor conversations. All financial projections are based on publicly available data, government policy documents, industry research, and conservative operational assumptions. Actual results may vary.
