en.Wedoany.com Reported - The Buffalo Campus, located in Twin Buttes, North Dakota, has commissioned its nearly 80-kilowatt (kW) off-grid solar and battery microgrid. The system, introduced with contributions from Shae Mitchell, co-founder of Sun Bear Industries, aims to reduce diesel dependence and enhance energy resilience. The microgrid utilizes JinkoSolar solar panels, Discover Helios battery energy storage systems (with a total capacity of approximately 300 kWh), and a Sol-Ark inverter platform. It is expected to generate around 100,000 kWh annually, saving approximately $50,000 in costs each year.

The system is designed with a rooftop solar array as the core power generation source, paired with large-capacity batteries to enable daytime charging and nighttime power supply. A backup diesel generator serves only as a reserve, activated during cloudy days or extreme weather, significantly reducing fuel consumption. The microgrid controller balances generation and load in real time to ensure a stable power supply. This project offers a replicable model for remote communities, promoting energy sovereignty and sustainable development.

The Buffalo Campus system not only reduces operational costs but also enhances energy reliability and decreases reliance on fossil fuels. Its successful implementation provides a reference for building off-grid microgrids in other similar locations.
