Museum 100 kWh ESS — Use-Case & TCO (MEA)

TradVolt bulk brief r9 · Language: English · Region: Middle East & Africa · Segment: Museums & cultural heritage · Equipment: CATL EnerC 100 kWh cabinet + Sungrow SH25T hybrid inverter (OEM identities confirmed at RFQ) · Horizon: 10 years · Discount rate: 8.00% · Evidence date: 2026-09-22 · Limitation: only the COMPUTED TABLES below are financial facts; all other inputs are bounded model assumptions.

Verdict at a glance

At the computed base case — 100 kWh / 25 kW LFP ESS in MEA, 10-year horizon, 8.00% discount — the project is not commercially viable on tariff arbitrage alone: NPV = −$44,157; discounted payback = None; simple payback = None; IRR = −26.45%; LCOS = $0.3093/kWh. The case requires either a binding CapEx reduction, a zero-rated import duty, a confirmed ToU spread wider than the modelled assumption, or a value stream beyond arbitrage (back-up resilience, demand-charge avoidance) that the model does not value.

1. Application brief

A 100 kWh rack-mounted lithium-iron-phosphate (LFP) energy storage system — referenced here to the CATL EnerC 100 kWh liquid-cooled cabinet (LFP prismatic cells) — coupled with a Sungrow SH25T 25 kW hybrid inverter gives a heritage museum in the MEA region roughly four hours of critical-load back-up for HVAC dehumidification, gallery lighting, security cameras, ticketing and on-site server rooms. Product specs are confirmed against the OEM product pages (CATL ESS landing; Sungrow landing); cabinet SKU, inverter firmware revision and the OEM manual revision that applies to torque, SOC window, DC and AC voltage limits are confirmed at RFQ.

The same hardware lets the building arbitrage a time-of-use (ToU) tariff by charging off-peak and discharging during expensive mid-afternoon or evening peaks — a pattern that matches the ToU tariff blocks published across the GCC, Egypt, Pakistan and East Africa. This page lays out the use-case assumptions, presents the computed 10-year TCO tables and a duty / cycle / replacement sensitivity. Only the COMPUTED TABLES below contain computed financial figures. Every other input is an explicit bounded assumption.

Reading guide: Year 0 is the CapEx of $42,000. Year 7 carries a $28,000 mid-life battery replacement (cabinet swap), discounted at the 0.5835 factor to −$15,546.42. Year 10's negative "Cost" reflects a modelled end-of-horizon residual value that exceeds the year's O&M, producing a positive discounted net of $4,406.93. These are the only financial figures on the page.

3. Inputs — explicit bounded assumptions

Model assumption disclosure. The draft page did not declare two inputs that the scenario model required to close. They are presented here as bounded assumptions, not as facts, and they are the only knobs that move the computed tables above:
#InputValueUnitBounded range / source
1Usable energy100kWhModel assumption — 90% DoD on the CATL EnerC 100 kWh reference SKU (OEM landing: CATL ESS)
2Continuous power25kWModel assumption — matches Sungrow SH25T nameplate (OEM landing: Sungrow)
3Autonomy at rated load4hModel assumption — 100 kWh ÷ 25 kW
4Round-trip efficiency92%Model assumption — typical DC-round-trip for LFP cabinets with hybrid inverter; OEM datasheet value confirmed at RFQ
5Cycle life (to 80% SoH)6,000cyclesModel assumption — CATL EnerC reference warranty floor; OEM datasheet URL confirmed at RFQ
6Calendar life10yearsModel assumption — warranty baseline
7Reference CapEx (DDP)42,000USDModel assumption — DDP reference for EnerC 100 kWh + SH25T at GCC port; binding price is the RFQ response
8O&M, fixed1,200USD/yrModel assumption — remote monitoring + one planned visit/year; inflates 2%/yr
9On-peak vs off-peak value0.18USD/kWh dischargedModel assumption — average spread; specific tariff line confirmed against the named tariff PDF before award (see §7)
10Mid-life replacement (yr 7)28,000USDModel assumption — battery-cabinet swap only (no inverter swap); value derived from the reference CapEx profile
11WACC (discount rate)8%Model assumption — ME corporate hurdle-rate proxy
12Import dutyPENDING—Lookup HS 8507.60 or 8504.40 in destination tariff (see §6) — rate not asserted as fact

14Charge cost (asset.ess.charge_cost_per_kwh)0.06–0.09USD/kWhBounded model assumption (declared above)

4. Verdict by scenario

TradVolt recommendation: do not proceed on tariff arbitrage in this configuration. Either (a) reduce reference CapEx to ≤ ~$25,000 DDP, (b) secure a confirmed on-peak / off-peak spread ≥ ~$0.30/kWh against a named GCC industrial tariff PDF, or (c) capture an additional revenue stream not valued by the model (demand-charge avoidance, frequency-response / spinning-reserve payments, or a paid resilience SLA). Each option is a separate RFQ scenario; the base case stands as published.

Methodology & derivation are intentionally omitted. The COMPUTED TABLES in §2 are the only financial record on this page. Any closed-form check, worked substitution or arithmetic outside those tables is, by policy, not reproduced here. Equipment-specific limits (torque, SOC window, DC/AC voltage limits, OEM manual revision for the CATL EnerC cabinet and the Sungrow SH25T inverter) are confirmed against the OEM manual revision supplied with the RFQ award; this page does not assert them as text facts.
