India's First
BESS as a Service.
PWRNXT owns, installs and insures the BESS — your organisation contributes ₹0*, with deployment beginning within 6–10 weeks of lease signing.
The Problem With Buying a BESS
Capital locked up, maintenance on your books, technology risk you didn't sign up for. Three problems no business case easily solves.
CapEx Approval Cycle
A ₹1–5 crore BESS investment requires board approval, capital budgeting cycles and competition against core business investment priorities. The approval process alone typically takes 6–18 months — during which your facility continues paying ₹25–30/kWh for diesel backup and absorbing every production outage event.
Technology Obsolescence Risk
Battery technology is advancing rapidly. An organisation that buys a BESS today owns an asset that will be technically inferior within 3–5 years — while continuing to depreciate it over a 10-year accounting life. You carry the stranded asset risk, not the technology provider.
Hidden Operations Burden
Owning a BESS means staffing or contracting for EMS operation, preventive maintenance, State-of-Health monitoring, critical spares inventory and fault response. Most C&I enterprises are not in the battery operations business — and this hidden OpEx rarely appears in the original ownership business case.
What Zero-Capex BESS Means in Practice
We carry the asset, the risk, and the maintenance. Four things change on your P&L from day one.
Zero Capital Investment*
PWRNXT purchases, finances, installs and insures the BESS asset. Your organisation contributes ₹0* to the installation. No CapEx approval required. No impact on your capital employed. Deployment begins within 6–10 weeks of lease signing — not after a 12-month budget cycle.
100% Tax-Deductible OpEx*
Operating lease payments are expensed as OpEx under Indian accounting standards — 100% tax-deductible in the period incurred. No capitalisation required, no depreciation schedule, no IND AS 116 balance sheet recognition under most operating lease structures. Your CA firm reviews the structure before you sign.
Off Balance Sheet*
The BESS asset sits on PWRNXT's balance sheet, not yours. Your capital employed, ROCE, debt covenants and leverage ratios are completely unaffected. For enterprises with balance sheet constraints, this is frequently the deciding factor — world-class infrastructure without touching your financial ratios.
Technology Risk Transferred
PWRNXT bears all technology obsolescence risk. If superior battery chemistry emerges during your lease term, we absorb the impact. At lease renewal, you can upgrade to the latest available system — not extend a depreciating old one. You are always accessing current-generation, warranted technology.
Owning BESS vs PWRNXT Lease
Every financial and operational dimension — ownership vs lease — compared side by side.
| Dimension | ⬜ Buy / Own BESS | 🟢 PWRNXT Zero-Capex Lease |
|---|---|---|
| Capital Required | ₹1–5 Cr upfront CapEx High Barrier | ₹0* — PWRNXT-owned and financed Zero Barrier |
| Balance Sheet Impact | Asset + depreciation on your books. Affects ROCE and capital employed. | Off-balance-sheet* — zero impact on ROCE, debt covenants or leverage ratios Clean Books |
| Tax Treatment | Depreciation over 5–10 year accounting life — deferred benefit | 100% expensed as OpEx immediately* — full Year-1 tax deduction Immediate Benefit |
| CapEx Approval | Board approval, budgeting cycle — 6–18 months typical | No CapEx approval — OpEx decision at business unit level Fast Decision |
| Technology Risk | You depreciate a 10-year asset as battery tech advances past it | PWRNXT bears all obsolescence risk — upgrade at lease renewal Zero Risk |
| Maintenance Cost | Variable — contract separately — ₹4–10L/yr hidden OpEx | Included in fixed quarterly lease — zero additional cost Predictable |
| Performance Guarantee | No SLA — performance degrades at your risk | Contractual 98.5% uptime SLA with defined remedies Enforceable |
| Cost Predictability | CapEx + variable maintenance + energy costs — unpredictable total | Single fixed quarterly payment — 100% cost predictability Fixed Cost |
| Asset Disposal | You manage end-of-life — recycling, salvage, accounting write-off | PWRNXT handles all end-of-life — zero residual obligation Clean Exit |
What This Looks Like On Your P&L
The ledger opposite shows a typical 500 kVA facility. Your current backup power spend — diesel, maintenance, operator, AMC — is replaced by a single quarterly PWRNXT lease line item on your P&L.
The key insight for most CFOs: the quarterly BESS lease is structured at or below your current quarterly all-in diesel spend. Cash flow impact on your P&L is neutral or positive from month one — before counting maintenance savings, production loss prevention or ESG compliance value.
For facilities also benefiting from Time-of-Day tariff arbitrage — cold storage, hospitals, campuses — the BESS generates additional value by peak-shaving during high-tariff windows, improving the economics further beyond pure backup replacement.

Feasibility Study
Share your energy bills and DG operational data. Our engineers conduct a techno-economic study — baselining your load, outage profile, and costs to right-size the BESS and quantify the financial case.
P&L & Lease Proposal
We model your complete P&L impact — lease cost, energy savings, maintenance savings, production loss prevention — alongside the lease term sheet. Fully auditable assumptions, nothing hidden.
Legal & Commercial Review
Standard 5–7 year operating lease. Your finance and legal teams review the SLA, exit provisions and performance guarantee terms. We disclose every clause transparently — no surprises at signing.
EPC & Go-Live
PWRNXT manages the full installation — design, procurement, civil works, commissioning and Site Acceptance Testing. System live within 6–10 weeks. PWRNXT operates everything from go-live.
The Commitments Behind Every Lease
A lease is only as good as the organisation behind it. Here's what you can hold us to.
Tier-1 OEM Components
PWRNXT systems are built on Tier-1 battery cells from CATL, BYD and EVE Energy, and power electronics from Sungrow and Delta — certified to UL 9540A, IEC 62619 and CE standards. LFP chemistry exclusively — no thermal runaway risk. This is what backs the 98.5% uptime SLA.
Contractual SLA, Not Best-Effort
The 98.5% uptime guarantee is a contractual obligation with defined remedies — not a marketing claim. If PWRNXT misses the SLA, the lease agreement specifies the applicable credit or remedy. Your finance team can model a worst-case scenario and it is covered in writing.
Proven in Live Deployments
Our Haryana auto ancillary deployment has operated across 200+ annual outage events with zero production impact. The operating lease model, SLA and EMS operations are all live, verified and auditable — not a concept proposal or pilot project.
Full Transparency on Lease Terms
Exit provisions, renewal options, technology upgrade paths, performance credit calculations — every clause is disclosed before you sign. We provide full documentation to support your auditors' IND AS assessment. Nothing is buried in the fine print.
24/7 Remote EMS Operations
Our Energy Management System monitors every BESS parameter continuously. Predictive fault detection flags our engineering team 2–4 weeks before any potential failure. Your facility team has zero BESS operational workload — ever. All included in the lease.
ESG and BRSR-Ready Reporting
PWRNXT EMS generates complete, auditable energy and emissions data. Every kWh dispatched, every outage prevented, every tonne of CO₂ avoided is logged and exportable for your annual ESG and BRSR reporting — directly from our system, no manual calculation required.
Zero-Capex BESS Lease FAQ
The questions CFOs and Finance Directors ask us most.
Is the PWRNXT operating lease truly off-balance-sheet under IND AS?
For most operating leases structured below the IND AS 116 recognition threshold, lease payments are expensed as OpEx without balance sheet recognition. PWRNXT provides full documentation of the lease structure to support your statutory auditors' assessment. We strongly recommend your CA firm reviews the specific structure before signing — and we make that review straightforward by disclosing every clause upfront.
How does zero-capex BESS work — who actually owns the equipment?
PWRNXT purchases, finances, installs and insures the BESS asset entirely. It sits on PWRNXT's balance sheet, not yours. You access world-class battery energy storage and pay a fixed quarterly operating lease. Your organisation contributes zero capital*, carries zero depreciation and bears zero technology risk throughout the lease term.
What happens at the end of the lease term?
At lease end you have three options: renew at a typically reduced rate reflecting the depreciated asset; upgrade to a new-generation BESS under a fresh lease — giving your facility the latest technology; or allow PWRNXT to remove the equipment cleanly. There is no residual value obligation, no balloon payment and no write-off risk on your side in any scenario.
How does the quarterly lease compare to current diesel generator costs?
For most clients, the quarterly BESS lease is structured at or below their current quarterly all-in diesel expenditure — covering fuel, maintenance, operator and AMC costs together. Given that BESS also eliminates production losses from the 10–30 second switchover gap, most clients see positive net cash flow from month one without heroic assumptions.
Can we terminate the lease early if our situation changes?
Yes. The lease agreement includes clearly defined exit provisions that we discuss openly before you sign. Early termination is possible subject to a termination fee that reduces progressively over the lease term. We design exit terms that are commercially fair — the goal is a long-term partnership, not a contractual trap.
Is the zero-capex model available for multi-site enterprise deployments?
Yes. PWRNXT can structure an enterprise-wide operating lease framework across multiple facilities — single master agreement, unified SLA and consolidated quarterly billing. Multi-site portfolios typically benefit from improved lease economics due to portfolio scale and reduced per-site commercial overhead. We have built this model for enterprise clients with 3–10 sites requiring BESS.
