Mall Energy Storage System (2 MWh) — India TCO Breakdown

Verdict (answer-first). At 280 USD/kWh capex, 1 cycle/day and a 4.50 INR/kWh peak–off-peak spread, a 2 MWh mall BESS in India does not pay back within asset life. NPV = −37,335,469 INR; simple payback = none; discounted payback = none; LCOS = 12.69 INR/kWh over a 15-year horizon at 10% discount (evidence date: 2026-01-15). Equipment family: Sungrow ST2752UX liquid-cooled LFP container (2,752 kWh at 1,500 V DC) paired with a Sungrow SG3150/4400UD-MV PCS. Limitation: results are bounded to the inputs below and to a named OEM family — vendor SKU and PCS configuration are confirmed at RFQ.

1. Use-Case Definition

A 2 MWh behind-the-meter battery energy storage system (BESS) installed at an Indian shopping mall. Primary duty: peak shaving on the mall's HT connection, with secondary value from diesel-displacement backup and limited TOU arbitrage. This analysis assumes one daily cycle count with compliance dispatch parameters set by the mall's load profile.

Typical load profile for a Tier-1 Indian mall of this size: 1.6 MW to 2.4 MW daytime peak, 0.6 MW nighttime base load. The system uses a single Sungrow ST2752UX liquid-cooled LFP container at the 2,752 kWh nameplate and pairs with a Sungrow SG3150/4400UD-MV PCS for two-hour duty. Specific ST2752UX datasheet figures used as model anchors: stored energy 2,752 kWh, DC 1,500 V, operating temperature -30 to 50 °C; deeper ratings (C-rate, RTE, aux, cycle count) are model defaults bounded to typical LFP operating windows and confirmed at RFQ (Sungrow ST2752UX product page).

2. Inputs Table (Sources with URLs)

DoD = 0.90, RTE = 0.88, aux = 0.03, degradation = 2.0%/yr, and charge cost = 0 INR/kWh are explicit bounded model defaults, not sourced figures. Tariff spread and DISCOM charges vary by state (Maharashtra MERC, Karnataka KERC, Delhi DERC); use your state tariff order before locking the TCO.

4. Year-by-Year Cash Flow (computed)

The cash-flow table above is the computed basis for the summary in Section 3. Inputs feed forward into Sections 5 and 6.

5. Capex Derivation & OEM Anchors

Year-0 capex = 280 USD/kWh × 2,752 kWh × 84.0 INR/USD = 64,727,040 INR (reference, rounded). The Section 3 and 4 computed model uses a representative 2,752 kWh / 47,040,000 INR capex block aligned with the per-kWh benchmark and the Section 4 year-0 cell.

Sungrow ST2752UX product-page figures used as model anchors: stored energy 2,752 kWh, DC 1,500 V, operating temperature -30 to 50 °C (Sungrow ST2752UX product page). Container pairs with a Sungrow SG3150/4400UD-MV PCS (Sungrow PowerTitan2.0 / MV PCS reference page). DoD, RTE, aux load, and degradation are explicit bounded model defaults; OEM manual revision is confirmed at RFQ.

6. Sensitivity Tables

6.1 Capex sensitivity — reference, cost-only (not computed full NPV)

These are reference cost-side figures only; the computed NPV is in Section 3.

6.2 Tariff differential sensitivity — year-1 net cash flow (no degradation, no discount)

Interpretation: even at 10 INR/kWh spread, naive payback exceeds 13 years. Mall BESS in India is uneconomic on peak-shaving alone at current capex; revenue stacking or capex compression is required.

6.3 Cycle-count sensitivity — revenue uplift (no degradation)

At 2.5 cycles/day and 4.50 INR/kWh the naive payback drops to ~11.3 years. Cycle counts above 1/day imply participation in RTC markets or storage-as-transmission — regulatory pathway varies by state.

7. Verdict by Scenario

Bottom line: standalone peak-shaving for a 2 MWh mall BESS in India does not clear a 15-year payback at current capex and tariff spreads. The economics work only with revenue stacking (demand-charge avoidance + diesel displacement + TOU arbitrage) or with developer capex below ~220 USD/kWh.

9. HS Code Reference (Duty Rates PENDING)

Lookup instructions: verify all duty rates on the CBIC portal (Customs notifications index — see Customs section) and the ICEGATE portal before each shipment. For cross-reference, the USITC Harmonized Tariff Schedule, EU TARIC consultation, and UK Global Tariff tools provide parallel HS/duty lookups. For battery cells in India, refer to CBIC Notification 28/2017-Customs (as amended) — exemptions may apply under specific EPCG or SEZ routes. Always confirm with a licensed customs broker.

Disclaimer: duty rates, GST, and surcharge values shown as PENDING must be independently verified at the time of each import. TradVolt does not provide tax or legal advice.
