System scale: 18 kWp solar PV, 24 kWh lithium-iron-phosphate (LiFePO₄) battery storage, 15 kW diesel backup generator, and smart energy management system.
Offshore Oil Platform Emergency Backup Modernization
Modernization of emergency backup power for a North Sea offshore oil platform (UK sector), replacing aging diesel-only standby generators with a certified, ATEX-compliant off-grid hybrid system. Platform supports 120 personnel and critical production & safety systems; peak emergency load: 4.2 MW; existing diesel gensets were 3× 2.5 MW units with 72-hour fuel autonomy.
Wildfire-Resilient Community Shelter in California
A 12,000 sq ft community shelter in Butte County, California—located in a high-fire-risk zone with frequent Public Safety Power Shutoffs (PSPS)—designed to house up to 250 evacuees for 14+ days without grid connection. The facility integrates emergency medical services, communications hub, and food/water distribution; powered exclusively by an off-grid hybrid power system.
Alaskan Remote Research Station Power Resilience Upgrade
Upgraded power infrastructure for a year-round, off-grid scientific research station located on the North Slope of Alaska (70.2°N, 148.5°W). The station supports 12 researchers and automated environmental monitoring systems, with peak load of 42 kW and average daily energy demand of 680 kWh. The original diesel-only system incurred high fuel logistics costs and reliability risks during 6-month winter darkness.
