Containerised 5.015 MWh BESS
Turnkey 5.015 MWh utility-scale battery energy storage in a standard 20ft ISO container.
High-density 314Ah Prismatic LiFePO₄ technology with closed-loop liquid cooling. Fully compliant with Indian CEA grid codes, VGF tenders, renewable solar/wind time-shifting, and industrial peak shaving.
The CLN Containerised 5.015 MWh Battery Energy Storage System (BESS) represents the pinnacle of high-density utility-scale energy storage in India. Housed within a standard 20ft ISO container, it integrates 12 modular battery clusters powered by high-capacity 314Ah Grade-A Prismatic LiFePO₄ cells.
Engineered specifically for harsh Indian operating conditions (from Rajasthan summer heat to coastal humidity), it utilizes industrial closed-loop liquid cooling, multi-gas fire detection, automated clean-agent suppression, and full CEA grid-code compliance for solar farm time-shifting, frequency regulation, and mega-industrial peak shaving.
Utility-Scale Engineering Highlights
Closed-Loop Liquid Cooling
Maintains inter-cell temperature variance strictly under ΔT < 2.5°C across all 12 clusters, extending operational cell life by up to 25% in 50°C summer ambient heat.
Multi-Hazard Safety & Fire Suppression
Early-warning CO/H2 gas detection, aerosol / Novec-1230 gas flooding, roof deflagration venting panels, and IP67 pack-level environmental sealing.
Ultra-High Energy Density (20ft ISO)
Delivers over 5 MWh in standard 20ft container footprint, minimizing civil foundation land footprint and simplifying road transport logistics across India.

Frequently Asked Questions — Containerised 5.015 MWh BESS
How much energy and power is housed within a single 20ft container?
A standard CLN Containerised BESS houses a nominal energy capacity of 5.015 MWh (5,015 kWh) within a standardized 20ft High Cube ISO shipping container. Depending on customer C-rate requirements (0.5C or 0.25C), it delivers between 1.25 MW to 2.5 MW of continuous AC active power discharge.
Why is liquid cooling superior to traditional air cooling for utility-scale BESS in India?
In extreme Indian climatic conditions where ambient summer temperatures exceed 45°C–48°C, air-cooled containers suffer from severe thermal gradients (temperature differences of 8°C–12°C between cells), causing rapid uneven cell degradation. CLN's closed-loop industrial Liquid Cooling system circulates coolant directly through internal pack cold plates, maintaining inter-cell temperature variance strictly under ΔT < 2.5°C. This boosts round-trip efficiency, prevents derating, and extends battery cycle life by up to 25%.
What multi-level fire suppression and safety mechanisms are integrated?
Safety is engineered into every layer: (1) Pack-level IP67 water/dust seal with aerogel thermal barrier between cells; (2) Multi-gas sniffer detection sensing carbon monoxide (CO), hydrogen (H2), and VOCs before smoke appears; (3) Clean-agent aerosol / Novec-1230 total flooding fire suppression; (4) Standardized roof-mounted explosion/deflagration pressure relief venting panels; and (5) External dry-pipe fire department water connection.
Is this system compliant with Indian Central Electricity Authority (CEA) and DISCOM grid codes?
Yes. CLN Containerised BESS units and integrated Power Conversion Systems (PCS) comply with CEA Technical Standards for Connectivity to the Grid, IEEE 1547, IEC 62933 (electrical energy storage systems), UL 9540A (thermal runaway fire propagation testing), and standard Indian Grid Code regulations for frequency support and reactive power control.
Can CLN BESS qualify for Viability Gap Funding (VGF) tenders in India?
Yes. CLN Energy designs and manufactures systems compliant with SECI (Solar Energy Corporation of India) and State DISCOM Viability Gap Funding (VGF) technical specifications, including domestic value-addition, high round-trip efficiency (>88%), and strict 6,000+ cycle guarantees.
What is the standard delivery, commissioning, and warranty support timeline?
Standard containerized units are pre-assembled, factory tested (FAT), and shipped ready for site connection. Turnkey commissioning typically requires 2 to 4 weeks upon civil foundation completion. Systems are backed by a 5 to 10-year performance and capacity retention warranty, supported by CLN Care engineers across India.
