Saint Joseph Mercy Health System builds on sustainability efforts with DTE Energy’s MIGreenPower program

Detroit, April 21, 2021 (GLOBE NEWSWIRE) --

  • St. Joe’s is the first health care system to enroll in MIGreenPower
  • Clean energy commitment will avoid more than 7,800 tons of CO2
  • Furthers St. Joe’s ongoing efforts to increase sustainability initiatives throughout its operations

Saint Joseph Mercy Health System (SJMHS), part of Trinity Health Michigan, today announced its enrollment in DTE Energy’s MIGreenPower voluntary renewable energy program. Through the program, SJMHS will purchase 10,000 megawatt hours of clean energy, which will offset greenhouse gas emissions equivalent to driving an average passenger car 17.8 million miles.* The clean energy projects that will source this purchase are currently under development and will begin operating in 2023.

St. Joe’s participating hospitals are St. Joseph Mercy Ann Arbor, St. Joseph Mercy Oakland and St. Mary Mercy Livonia.

“For our patients, employees and communities, we know that reducing pollution is important to the health of both our bodies and our planet,” said Rob Casalou, president and CEO, Trinity Health Michigan. “We already have several measures in place to increase sustainability practices across our system. Enrolling in MIGreenPower helps us build on our own environmental targets and support a cleaner Michigan.” 

SJMHS joins more than 300 Michigan businesses and 28,000 residential customers who are using MIGreenPower to reduce their impact on the environment. Prominent business subscribers include General Motors, Ford Motor Company, the University of Michigan and the Detroit Zoo. Launched in 2017, MIGreenPower now ranks among the top three voluntary renewable energy programs in the U.S.

“We appreciate St. Joe’s participation in our MIGreenPower program,” said Trevor Lauer, president of DTE’s electric company. “The tremendous support we’ve received from St. Joe’s and the other businesses and residential customers who have joined this program is accelerating the development of Michigan-made renewable energy. Bringing more wind and solar energy to the grid helps create a clean energy future for all Michiganders. It also strengthens Michigan’s economy, supporting jobs and bringing additional revenue to rural communities.”

With 18 wind parks and 31 solar farms, DTE is Michigan’s leading renewable energy producer and investor. Since 2009, the company has driven investment of $3 billion in renewable energy infrastructure and will invest an additional $2 billion in wind and solar assets over the next three years. DTE’s renewable energy projects have created or sustained more than 4,000 Michigan jobs and generate enough clean energy to power 670,000 homes.
