This Earth Day, WEICan is showcasing how energy storage can support a cleaner, more reliable grid.

From January through March 2026, WEICan operated its 111.5 kW / 223 kWh Battery Energy Storage System (BESS) to demonstrate demand peak shifting in support of the local power system.

The system was charged during periods of lower demand, when our wind park was generating renewable energy, and discharged during peak demand windows (6:00–10:00 AM and 4:00–8:00 PM). This approach helps reduce strain on the grid when electricity demand is highest, while maximizing the use of clean energy.

While our BESS is demonstration-scale (i.e., the maximum power output of our battery is just over 100 kW, compared to a peak load on the PEI grid of just over 400 MW in 2026, roughly 4,000 times larger), these systems are scalable and it reflects the same principles used by larger energy storage systems across the country. These systems play a critical role in improving grid stability, enabling higher penetration of renewables, and supporting the transition to a net-zero electricity system.

At WEICan, we’re proud to be testing and demonstrating solutions that help build a more sustainable energy future.
