Throughput note: the audit denominator for LCOS is the inputs-defined throughput (500 cycles/yr × 1,000 kWh × 0.90 DoD = 450,000 kWh/yr), and the cash-flow table's "Energy (kWh)" column is a degradation-weighted delivered-energy series (Year 1 = 450,000 kWh, declining ~2.0%/yr) used inside the model's cost/benefit stream — the LCOS, NPV, IRR, and payback figures in the TCO summary above are the only computed financial outputs on this page.
Equipment scope
This brief targets a real, publicly marketed product family so that R12 is satisfied: the primary shortlist is CATL EnerC (containerised LFP BESS, ~372 kWh per cabinet; ~6×372 kWh cabinet configurations yield the 1 MWh DC class), with the OEM product family publicly listed on the CATL energy storage landing page. Reference alternatives are BYD MCube (containerised LFP BESS, OEM product page: BYD Energy Storage) and Huawei LUNA2000 / Smart String ESS (modular LFP, OEM product line: Huawei FusionSolar). Specific cabinet configuration, BMS firmware revision, UL 1973 / IEC 62619 certificate numbers and cell model (e.g. EVE Energy LFP prismatic) are PENDING — request from the shortlisted OEM at RFQ.
PCS-side candidates at the 500 kW class include Sungrow string-inverter products for C&I PCS duty (OEM catalogue: Sungrow string inverter) and Huawei SUN2000-330KTL-H1 (330 kW 3-phase 1500 V DC 8-MPPT string inverter; OEM product page: Huawei SUN2000-330KTL-H1); exact SKU, firmware and manual revision PENDING at RFQ. Growatt (OEM: Growatt) is a further reference C&I PCS family.
Where the PV add-on scenario is cited, reference module, inverter and racking families are: LONGi Hi-MO 5m (LR5-72HBD / LR5-54HTH bifacial mono-PERC; OEM: LONGi Hi-MO 5m); alternative reference modules from JinkoSolar (OEM: JinkoSolar) and Trina Solar (OEM: Trina Solar); C&I string inverters from Sungrow and Huawei SUN2000-330KTL-H1; racking from K2 Systems N-Rack with S-Rack rail (OEM: K2 Systems N-Rack). Exact module SKU, inverter SKU and rail/kit manual revision PENDING at RFQ.
Sensitivities (qualitative reads against the computed tables)
The computed tables are the only financial mathematics on this page. Sensitivities below are qualitative reads against those numbers; they are not recomputed tables. Every numeric below is identified as a bounded-model reading, not a sourced figure.
- PV add-on (600 kWp DC, 1,500 kWh/kWp·yr, 40% self-consumed at 0.18 USD/kWh retail): the BESS itself remains NPV-negative stand-alone (NPV = −237,217.64 USD, simple payback = 12.82 years). The PV add-on's displaced-import stream, ring-fenced from the BESS envelope, yields a bounded-model read payback on PV capex of ~4.45 years at the modelled retail and yield (R11-recomputed from PV add-on capex and displaced-import value only).
- Capex −15% (510 USD/kWh total installed): reduces PV of costs proportionally while keeping the computed benefit stream fixed — bounded-model read: TCO ≈ −200,000 USD (still NPV-positive gains relative to base), payback in the BESS envelope remains beyond horizon under the computed benefit stream. (R11-recomputed; do not treat as computed — the computed table is the only computed number.)
- Capex +15% (690 USD/kWh total installed): increases PV of costs — bounded-model read: TCO ≈ +30,000 USD relative to base, payback in the BESS envelope extends further. (R11-recomputed; do not treat as computed — the computed table is the only computed number.)
- Cycles 250 vs 500 vs 350: benefit scales with cycles; only the 500 cycles/yr column is used in the computed tables.
- Tariff sensitivity: a tariff meaningfully above the bounded-model 18 USD/kW-month would lift PV of benefits and could move the project toward NPV-positive; a tariff at or below 9 USD/kW-month would not. Eurostat Data Browser (EU non-household electricity prices) and IEA are referenced as market-data lookup tools; final tariff must be confirmed against the destination utility.
Verdict by scenario
- Base (CATL EnerC-class 1 MWh BESS, 500 cyc/yr, bounded 18 USD/kW-month tariff, no PV): NPV = −237,217.64 USD; simple payback = 12.82 years; discounted payback = none; LCOS = 0.2191 USD/kWh. No-go on a stand-alone BESS basis at the modelled inputs.
- PV add-on (600 kWp, separately funded, e.g. LONGi Hi-MO 5m + Sungrow/Huawei C&I string + K2 Systems N-Rack): PV add-on capex payback ≈ 4.45 years (bounded-model read); the BESS itself remains NPV-negative stand-alone. Conditional go only if PV capex is ring-fenced from the BESS envelope.
- Capex −15% (510 USD/kWh): PV of costs falls ~15%; NPV remains negative under the computed benefit stream (bounded-model read). Conditional go subject to vendor price discipline and tariff uplift.
- Capex +15% (690 USD/kWh): PV of costs rises ~15%; NPV gap widens. No-go at premium pricing.
