GreenPower has developed the “Mega Beast” electric school bus with a range of 300 miles. The company claims that the 387 kWh battery of the bus is the largest among all school buses. The bus can carry up to 90 people and has an autonomous range of nearly 500 miles.

The long-wheelbase Type D model uses a lithium iron phosphate (LFP) battery, which provides high energy density and longer lifespan. However, its initial cost is higher.

Why such a long range when buses usually make only two trips a day? This version is designed for longer routes, such as rural schools or school districts where it is not possible to charge the bus at noon.

It also targets regions with “extreme weather conditions and schools that use all-electric buses for extracurricular activities.” Large electric school buses with a range of about 100 miles can cost between $300,000 and $400,000, which is four times more expensive than a diesel-powered school bus. However, maintenance costs are lower.
