GM saves US$5m annually from using renewable energy

All GM's Ohio and Indiana manufacturing facilities, including those building the Chevrolet Cruze, Silverado and GMC Sierra light-duty pickup trucks, are to meet their electricity needs through 100% renewable energy.

GM is buying a total of 200 megawatts of wind energy from Ohio and Illinois wind farms. Once the turbines come online by the end of 2018, renewable energy will power 20% of GM's global electricity use.

"Congratulations to GM on this huge progress leap – a fantastic show of commitment at Climate Week NYC and all achieved in just a year since the company joined RE100," said The Climate Group CEO, Helen Clarkson.

"GM vocally champions the compelling business case for renewables and shares learnings with other companies. It shows other companies what's possible."

The new wind deals are enough to meet the electricity needs of Fort Wayne Assembly, Marion Metal Centre and Bedford Casting plants in Indiana and Lordstown Assembly, Defiance Casting Operations, Parma Metal Centre and Toledo Transmission plants in Ohio.

"Technology is driving solutions for mobility and safety in our vehicles, as well as the new energy solutions that build them," said GMNA Manufacturing and Labour VP, Gerald Johnson.

"This is the way we do business: offering vehicles that serve our customers' lifestyle needs while providing sustainable solutions that improve our communities."

GM is leveraging energy efficiency and a mix of onsite and offsite renewable energy solutions to reach its 100% renewable energy goal. The company's four-part strategy acknowledges how its energy and product strategies intersect.

The company uses EV batteries in tandem with a solar array to power an office building at its Milford Proving Ground in Michigan and is researching the use of fuel cells as energy storage in the future.

"We're helping provide solutions to green the grid through these new renewable energy deals and sharing best practices with other companies so they too can reduce risk and energy costs," said GM global manager of renewable energy, Rob Threlkeld.

"With a pragmatic strategy, companies can turn ambitious renewable energy goals into action and scale quickly."

Altenex, an Edison Energy Company and independent renewable energy adviser, supported GM in the negotiation of the power purchase contracts. GM will be the sole user of the Northwest Ohio Wind farm, a 100 MW project owned by Starwood Energy Group. Swift Current Energy will provide 100 MW from its HillTopper Wind Project in Logan County, Illinois.

GM has used renewable energy for decades, saving about US$5m annually as a result. GM made its first wind purchase in 2014 for several of its Mexico operations, followed by deals supporting Texas wind farms for 30 and 50 megawatts of energy.

The company uses solar power at 26 facilities and generates electricity from landfill gas at two assembly plants.
