India's EV Boom
Starts With the
Right Infrastructure.
Up to 100% on upstream infra for Govt sites. 80% for commercial. Captured at proposal stage.
What Your EV Chargers Actually Cost Today
The three biggest reasons EV charging India deployments fail to break even - before a single session is counted.
Fixed Charges vs Low Utilisation
A 100 kW sanctioned load carries ₹3-5 lakh per year in fixed demand charges - from day one, before a single EV plugs in. At sub-8% charger utilisation, fixed costs dominate the P&L.
Feeder Upgrades and Sanctioned Load
Multiple DC fast chargers on a weak feeder trigger DISCOM transformer augmentation demands - ₹10-25 lakh before a single charger energises. Oversizing to future-proof means paying excess fixed charges for years.
Slow Charging, Lost Customers
Insufficient grid headroom forces charger throttling. A 150 kW charger delivering 60 kW means 2.5× longer sessions, queues, and negative reviews - revenue lost before the market matures.
The Underlying Problem: Infrastructure Design, Not Charger Brands
Most EV charging station failures trace back to upstream electrical design, not the EVSE. PWRNXT designs the grid connection, infra, and charger stack as one engineered system.
PM E-DRIVE Subsidy - Built In from Day One
Every PWRNXT deployment is proposal-ready for PM E-DRIVE from design stage - maximum subsidy captured, zero compliance risk at disbursement.
Compliant from Upstream Infra to Hub Onboarding
PM E-DRIVE requires commissioning, standards compliance, and Hub live data as subsidy conditions. PWRNXT delivers all three as standard - no gaps at handover.
You focus on your business. PWRNXT manages the regulatory complexity that determines whether the subsidy is realised.
Check Your Site's CategoryBuilt for Real Distribution Networks, Not Lab Conditions
India's distribution network was not designed for EV loads. Every PWRNXT EV charging India deployment is engineered around actual grid conditions - not OEM nameplates.
Grid-Aware Sizing
Full load flow analysis of your sanctioned load, transformer headroom, and feeder constraints. Charger capacity sized to actual grid reality - not OEM nameplate figures.
Protection Against Nuisance Tripping
Full protection coordination - diversity factors, relay settings, earth fault protection. A fault on one circuit never brings down the whole charging station or site supply.
Layout for Fast Fault Isolation
Cable routing, panel location, and bay design engineered for rapid isolation. A tripped charger is restored without impacting adjacent circuits or base site load.
BESS-Ready Architecture
Pre-allocated switchgear bays, cable ducts, and physical footprint for future BESS. The upgrade path is defined and costed before you commission - not designed under pressure later.
National Unified Hub - Live at Go-Live
Hub integration is a PM E-DRIVE subsidy condition. PWRNXT completes it at commissioning - your disbursement claim is never delayed by a data step nobody budgeted for.
CPO-Agnostic Deployment
PWRNXT builds the physical layer. You choose your CPO - or switch later. We integrate with any OCPP-compliant backend at commissioning, with no commercial bias.
Right-Sized for Your Grid. Built for Your Site.
Every site has a different grid reality. PWRNXT matches the charging station design to what your transformer and feeder can actually support - not to a generic brochure.
- For sites where the existing grid connection and transformer capacity can absorb the EV charger load without augmentation
- Full feasibility study confirms load headroom - charger mix sized to available sanctioned load
- Upstream electrical design and turnkey EPC - HT/LT, switchgear, civil
- EVSE selection and installation per MoP Guidelines and IS 17017
- PM E-DRIVE proposal data preparation (Annexure B/C/D) for nodal agencies
- Commissioning, testing, and National Unified Hub live onboarding
- AMC available - 98.5% uptime SLA, 24/7 remote monitoring
- For sites where transformer capacity is sufficient in aggregate but simultaneous EV charging could breach limits
- Dynamic load management curtails individual charger output when the site approaches its sanctioned load ceiling - the Indian approach to maximising value from limited grid capacity
- Every charger delivers as much power as available headroom permits at any moment - no single charger is permanently throttled
- EMS/site controller integrated from day one to enforce power limits automatically
- Pre-allocated switchgear bays and footprint for future BESS addition if load grows
- Structured upgrade pathway to Option 3 with pre-costed BESS scope
- For premium locations where transformer capacity is not available and a new DISCOM connection is unviable or uneconomical
- BESS sized to store off-peak grid power and dispatch during EV charging sessions - chargers run at full rated output without touching the sanctioned load ceiling
- Eliminates the need for sanctioned load augmentation entirely at constrained sites
- ToD arbitrage: charge BESS at low off-peak tariff, discharge during peak sessions - reduces effective energy cost
- Full EMS with SOC management, demand event alerts, and performance reporting
Generic Chargers vs PWRNXT Managed Load
Every parameter your infrastructure, finance, and operations teams care about - side by side.
| Parameter | 🔴 Generic Grid-Only EV Chargers | 🟢 PWRNXT Managed Load |
|---|---|---|
| Sanctioned Load Requirement | Full installed charger capacity - no optimisation Oversized | Diversity-factor sized - 20-35% lower sanctioned load for same EVSE count Right-Sized |
| Fixed Demand Charges | Full load × DISCOM demand rate from day one, regardless of utilisation Maximum Exposure | Reduced by right-sizing; load management logic prevents demand spikes Reduced |
| Simultaneous Fast Charging | Throttling likely when multiple chargers run at full rated output Throttled | Protection coordination ensures rated output within grid constraint Rated Output |
| Grid Overdraw / Penalty Exposure | High - uncoordinated load can trigger DISCOM penalties or disconnection High Risk | Load management logic and protection prevents overdraw events Managed |
| PM E-DRIVE Subsidy Alignment | Typically misaligned - upstream infra costs may not match benchmark eligible items Subsidy Risk | Proposal-ready from design stage - Annexure B/C/D data prepared by PWRNXT Zero Risk |
| Upgrade Complexity When Traffic Grows | Full redesign - switchgear, cable routes, and load calculations all change Major Rework | Modular upgrade: BESS slots into pre-designed bays - no redesign required Plug-In Upgrade |
| National Unified Hub Integration | Often done post-commissioning, risking subsidy disbursement delays | Live at commissioning - zero disbursement delay risk Day 1 Live |
| Uptime SLA | None - charger OEM warranty only, no site-level SLA | 98.5% contractual · 24hr on-site MTTR · 24/7 monitoring Contractual |
| DISCOM Coordination | Site owner responsibility - variable timelines, compliance risk | PWRNXT-managed - applications, demand notes, safety compliance Zero Burden |
Locations Where PWRNXT EV charging station Wins from Day One
EV charging India economics vary sharply by site type. These are the locations where PWRNXT's subsidy-aligned, grid-aware design delivers the strongest outcome.
Malls & High Streets
2-4 hour dwell times mean guests leave fully charged. EV charging converts idle parking bays into a footfall driver and revenue stream.
PM E-DRIVE Category COffice Parks & IT Campuses
Predictable 9-6 occupancy creates bankable utilisation. Managed Load delivers 80% upstream subsidy and a documented ESG outcome from day one.
PM E-DRIVE Category CHospitals & Hotels
Premium demographics, high staff EV adoption, and existing DISCOM infrastructure with headroom for charger addition without a new service connection.
PM E-DRIVE Category CMetro, Rail & Airport Parking
Category B - 80% upstream, 70% EVSE subsidy. High throughput, captive users, standardised multi-site designs. Highest-return Category B deployment type.
PM E-DRIVE Category BOMC Retail Outlets
Existing DISCOM connections, canopies, and land - the three costliest EV charging station inputs. Category B subsidy makes portfolio-scale rollouts immediately viable.
PM E-DRIVE Category BGovernment & CPSE Premises
100% subsidy on upstream infra and EVSE. PWRNXT manages the nodal agency proposal - removing the single largest implementation barrier for public sector EV charging station.

PM E-DRIVE funds up to 80% upstream + 70% EVSE for Category B, cutting payback from 8-10 years to ~2 years on net client investment.
PWRNXT builds, DISCOM connects, Hub goes live - your CPO starts collecting from day one. No rework, no resubmission, no compliance gap.
