BESS Energy Storage from 1 MWh to 1000 MWh
Short answer
We deliver containerised energy storage systems ranging from 1 MWh to over 1000 MWh. Base block: 1 MW power / 2 MWh capacity in a liquid-cooled 20 ft container with LFP cells. Modular configuration lets you scale the installation without changing the system architecture.

What project scale are you interested in?
You are not choosing a model — you are choosing a scale. We match container configuration, power and C-rate to the MWh you need.
1–3 MWh
manufacturing plants, EV charging stations, 0.5–2 MW PV farms
1 × 20ft container · 0.5–1.5 MW · 0.5C (2h) or 0.25C (4h)
3–10 MWh
2–5 MW PV farms, large industrial plants
2–3 × 20ft containers · 1.25–2.5 MW · 0.5C standard, 0.25C for shifting PV output
10–50 MWh
IPPs, grid-scale projects, capacity market auction participants
4–8 × 20ft containers · 5–25 MW · 0.5C for the capacity market, 0.25C for ancillary services
50–200 MWh
IPP developers, infrastructure funds
16–20 × 20ft containers · 25–50 MW · 0.25C (4h) most commonly, 0.5C for a capacity profile
200–1000+ MWh
utilities, public tenders, infrastructure fund portfolios
150–200 × 20ft containers in 50 MWh blocks · 125–250 MW · 0.25C (4h), optionally 0.125C (8h)

Architecture
Base block: 1 MW / 2 MWh in a 20 ft container
Every project, regardless of scale, is built from the same repeatable blocks. This means scaling up never requires redesigning the system.
20 ft container
6.06 × 2.44 m, weight 30–38 t, 5.0–6.9 MWh per unit. Transport without oversize permits.
Liquid cooling
Cell operating window of 15–35°C regardless of weather. Own consumption of 1.5–2.5% of throughput energy.
LFP cells
CATL, EVE Energy, Hithium, BYD. 8,000–11,000 cycles, 10–12-year guarantee at 70% SOH.
PCS and EMS
1.25–2.5 MW PCS at 98.3–98.8% efficiency, EMS integrated with SCADA and the balancing market.

Applications
The same architecture, a different revenue model. Choose the scenario that fits your asset.
2–40 MWh
Solar Farm
No more negative prices and curtailment — shift production to the evening peak.
1–10 MWh
Manufacturing Plant
Peak shaving and capacity-fee reduction for contracted capacity of 1–10 MW.
10–100 MWh
Capacity Market
A standby capacity agreement for a storage unit in a 2h configuration.
10–200 MWh
Ancillary Services and DSR
aFRR, mFRR and demand-side response (DSR) as a second revenue stream from the same installation.
1–3 MWh
EV Charging Station
A 300 kW charger on a 100 kW connection without grid expansion.
1–20 MWh
Limited Grid Connection
Storage instead of connection upgrades — faster and cheaper than new connection terms.
5–100 MWh
Wind Farm
Smoothing the production profile and operating within a limited connection point.
5–50 MWh
Data Center
Backup power and arbitrage from a single asset.
Numbers, not adjectives
LFP cells: CATL, EVE Energy, Hithium, BYD
The cell manufacturer matters more than the logo on the container. Our quotes always specify the exact model and cell capacity.

| EVE Energy | LF628 | 628 Ah | 10,000 | 10 years / 70% SOH |
| Hithium | MIC 1130 | 1,130 Ah | 11,000 | 12 years / 70% SOH |
| BYD | Blade 2 | 710 Ah | 10,000 | 10 years / 70% SOH |
| REPT Battero | Wending 320 | 320 Ah | 8,000 | 10 years / 70% SOH |
| CALB | L500 | 587 Ah | 10,000 | 10 years / 70% SOH |
