General Motors (NYSE:GM) will use 100 percent renewable energy to power its global technical center in Warren and a large part of its Detroit-based world headquarters at the Renaissance Center.

About 300,000 megawatt-hours of wind power, enough to power about 30,000 households per year, will come from DTE Energy Co.'s MIGreenPower program, said GM and DTE in a statement. Nationwide, GM said its renewable energy deals to date total 1.71 terawatt hours, more than any other automaker in the region.

"Investing in renewable energy remains an important part of GM's vision for a zero emissions future," said Rob Threlkeld, GM's global manager of Sustainable Energy and Supply Reliability, in a statement. "Our partnership with DTE Energy will help us get closer to achieving our goal of powering all our operations in Michigan with 100 percent clean energy. It helps demonstrate that local and regional industry partnerships are paramount to GM's clean energy future, where renewable sources will account for 100 percent of our global energy footprint by 2050."

Last week, Ford Motor Co. signed a similar deal with DTE for 500,000 megawatt hours through MIGreenPower.

DTE said it plans to build or acquire new wind projects to source the MIGreenPower program that Ford has joined. The Detroit-based company did not say where they would be located as sites are being investigated. The company now has 13 wind parks and 31 solar arrays. The wind parks are in the Thumb and mid-Michigan. The utility said it plans in March to commission its largest park so far, in Gratiot and Isabella counties in Mid-Michigan.

"Knowing that access to more renewable energy is important to our largest corporate and industrial customers, DTE will continue to expand MIGreenPower to help customers meet their sustainability targets," said Trevor F. Lauer, DTE Electric's president and COO, in a statement. "We appreciate GM's environmental leadership and are excited that we can partner with them through MIGreenPower to deliver on their clean energy goals."

In January, the Michigan Public Service Commission approved a special rate structure for DTE to expand MIGreenPower, its voluntary renewable energy program for large corporate and industrial customers.

GM is the second company, after Ford, to take advantage of this new structure. In 2017, DTE launched a slightly different MIGreenPower voluntary program to residential customers in which people pay extra on their monthly bills to support renewable energy capacity. Customers can invest in DTE-owned wind and solar farms by paying about $5 extra per month. Michigan's 2016 energy law mandated utilities to create a green pricing program for customers.

Once the new renewable projects supplying the program are online, GM, Ford and other future industrial customers that subscribe to MIGreenPrower will pay an additional rate charge equivalent to construction and ongoing operation costs, DTE said. Customers also will receive a bill credit based on lower regional projected energy costs.

GM officials also said the company now generates 20 percent of its global energy supply from renewables. Some projects include the following:

Cactus Flats — The Texas-based wind farm helps GM's Arlington Assembly run on 100 percent clean wind energy. The 148-MW facility based in Concho County operates in partnership with Southern Power.

HillTopper — Enel Green Power's first U.S.-based wind farm, of which 100 MW provide 100 percent renewable electricity to all of GM's Indiana and Ohio manufacturing facilities.

GM also is a member of the Renewable Energy Buyers Alliance and an early signatory of RE100, a collaborative global initiative uniting influential businesses committed to 100 percent renewable electricity, working to massively increase demand for and delivery of renewable energy.

DTE plans to double its renewable energy capacity over the next five years, investing in another $2 billion by 2024. It also proposes to build at least 3,000 more megawatts and solar and wind energy over the next 20 years. DTE currently produces about 1,000 megawatts of renewable energy, primarily wind. Each 1,000 megawatts powers about 450,000 homes.

Two thousand megawatts would power about 40 percent of the company's 2.2 million electric customers in Michigan. DTE said it will reduce carbon emissions by more than 80 percent by 2050.

"Our 100 percent renewable energy commitment, along with our pursuit of electrified vehicles and responsible manufacturing, is part of GM's approach to strengthening its business, improving communities and addressing climate change," said Threlkeld.
