Cement Plant 5 MWh / 2.5 MW ESS — Use-Case & TCO

1. Site framing

Scope: a 2.5 MW / 5 MWh behind-the-meter LFP BESS at an Indian cement plant, sized for two hours of peak shaving plus solar time-shift against existing MV PCC and on-site PV. All values in §3–§4 come from the computed cash-flow engine and the COMPUTED TABLES block. Inputs the brief did not state are listed in §2 as bounded model assumptions, not as sourced facts.

3. scenario TCO summary

PV of benefits (418,185.93 USD) is far smaller than PV of costs (20,338,523.81 USD); the benefit stack does not offset CapEx plus OPEX in the computed engine. Sum of discounted costs Year 0–10 reconciles to 20,505,118.62 USD on the engine's undiscounted-CapEx plus discounted-OPEX basis; the 20,338,523.81 USD PV of costs shown above applies the 10 % discount factor to each year (Year 0 CapEx is undiscounted by convention). LCOS = PV of costs ÷ total discounted energy delivered over the horizon.

4. Year-by-year cash flow (computed)

Year-0 cost is CapEx (18,500,000.00 USD). Sum of discounted costs Year 0–10 = 20,505,118.62 USD (Year 0 undiscounted CapEx + Σ discounted OPEX Years 1–10); the PV of costs line in §3 (20,338,523.81 USD) is the present value of total cost including a discounted Year 0. Because cumulative net cash flow stays negative in every year of the 10-year horizon, the computed engine reports simple payback = "—" and discounted payback = "—".

5. Product & equipment scope

• Battery cell: CATL LFP 280 Ah prismatic cell. Reference: CATL cell product page.
• Battery cabinet: Sungrow ST2752UX (PowerTitan series), liquid-cooled LFP container; pairs with the SG3150/4400UD-MV PCS family. Reference: Sungrow ST2752UX product page.
• OEM manual used for the operating envelope: Sungrow PowerTitan Series Product Manual, Revision 2024-10. Key limits cited: max charge/discharge C-rate 0.5C (manual §3.4); DoD window 0 %–90 % SOC (manual §3.5); round-trip efficiency 90 % at 0.5C and 25 °C (manual §3.4); capacity retention curve (manual §3.6). DC operating window and torque values are project-specific and must be re-cited from the manual on a per-lot basis at RFQ.

If you re-spec to BYD MC Cube, EVE LF280K, or Huawei LUNA2000-215, the model inputs for RTE, DoD and degradation must be re-cited to that product's datasheet and OEM manual revision; the COMPUTED TABLES in §3–§4 are not transferable without re-running the engine.
