Spark EV newly LEED-certified motor plant 6% powered by renewables

The electric motor and drive unit for the Chevrolet Spark EV are being manufactured in Maryland under a rooftop solar array in a newly LEED-certified building. The greening of the General Motors Baltimore Operations complex included the addition of 580 kilowatts of solar to the roof of its e-Motor building. Together with a 1.23-megawatt solar array on its grounds, 6% of the facility’s electricity comes from renewable sources.

The US Green Building Council certified the building as LEED Silver for environmental upgrades such as the solar array, installing LED exterior lighting and using compact fluorescent lighting in production areas.

Employee efforts to further reduce the building’s carbon footprint led to its surpassing the voluntary US Environmental Protection Agency’s ENERGY STAR Challenge for Industry, which requires a 10% reduction in energy intensity within five years. Baltimore joins 70 achievers in GM, which is the global leader of the challenge.

Maryland Energy Administration recognized Baltimore Operations with its Game Changer award for a smart microgrid charging technology created and managed in partnership with TimberRock Energy Solutions and OnStar. A solar array and solar EV charging canopy traps the power of the sun to create energy, which is used to charge the facility’s fleet of Chevrolet Volts or stored in an integrated storage system that can support the grid.

The facility also supports community-based organizations committed to advancing environmental awareness and education. Employees mentor local students in watershed quality and improvement projects and Baltimore Operations maintains a wildlife habitat certified by the Wildlife Habitat Council.



You would think they could get it to 25% without much of a problem, just add a load of solar equal to say 80% of the normal daytime load.
Maybe as high as 30% with solar alone.

A good bit more with wind+solar to say 55%.

After that, it starts to get hard (and expensive) - you need storage, or just use the grid as a huge battery.

This applies globally (in sunny places) - getting to 25% should be easy: then add wind, then it gets hard.


WOW:..a big 6% after 100+ years of operation.
