100MWh-Level 24-Hour Off-Grid in the USA
Project Overview
BESS for Data Center in the USA showcases a 100MWh-level off-grid solar-and-storage solution built to power a high-reliability data center 24/7 in a remote desert environment with extreme temperature swings and heavy dust exposure.
In response to the rapid expansion of AI data center development in the United States, FFD POWER deployed an off-grid solar-plus-BESS solution to power a high-reliability data center. Engineered for extreme temperature swings and high dust exposure in the desert, the system provides continuous, resilient power without grid connectivity.
Project Background
High-availability data centers require stable, high-quality power, but remote desert locations often lack dependable utility infrastructure. This project was developed as a fully autonomous energy system, combining high-performance solar generation with large-scale battery storage and environmental hardening to sustain 24-hour operation in harsh conditions.
Project Challenge
- Off-Grid Requirement: The site operates without utility grid access, requiring full-time autonomous power supply.
- Harsh Environment: Wide temperature fluctuations and persistent dust/sand exposure demanded robust thermal management and enclosure protection.
- Reliability Target: Data center uptime requirements necessitated redundancy and fault-tolerant battery architecture.
FFD POWER Solution
FFD POWER implemented a desert-ready off-grid “Power Sation” that integrates solar generation, large-scale BESS, and protected computer housing within the cabinet system, backed by a parallel battery-pack configuration for resilience.
System Specifications
- PV installed : Multi-MW-class solar array
- BESS POWER : 4 MW
- BESS capacity : 100 MWH
- Product used : Galaxy 215 All-in-one Cabinets
- Architecture: Fully off-grid solar + BESS microgrid with redundant parallel battery packs and desert-grade environmental protection
Operational Logic: 24-Hour Off-Grid Resilience
The system is optimized to maintain uninterrupted data center power under variable solar conditions and component-level faults:
- Daytime Supply and Storage: Solar generation directly supports the data center load while charging the BESS with surplus energy.
- Nighttime and Low-Solar Operation: The BESS discharges to sustain continuous power delivery when solar output is insufficient.
- Fault-Tolerant Continuity: Parallel battery-pack configuration, cabinet-level thermal control, and dust-resistant design maintain operation even if a single pack is isolated.
