When combined with existing renewable energy efforts, the building materials provider says the solar initiative will help the plant self-generate 75% of its electric power needs with green energy—an important step toward fulfilling Holcim's pledge to power all of its US operations with 100 percent renewable energy by 2030.
"The solar project on 100 acres of Holcim's Alpena property is another powerful example of the investment we are willing to make to address sustainability with urgency," said Atl Martinez, vice oresident, procurement at Holcim. "With new initiatives launching across the US, Holcim's momentum to transform our operations, lower our carbon footprint and reach net-zero has never been greater."
The announcement follows the recent opening of an innovative tire-derived fuel (TDF) facility at the Alpena plant. Holcim launched the $7.4 million initiative to safely and cleanly convert 22,000 tons of tires per year into energy to help fuel the plant. Built with support from the State of Michigan, the facility will allow the plant to sustainably reduce its reliance on fossil fuels and other natural resources, while diverting tires from landfills and streams.
On the horizon, the plant is planning upgrades to its dock used to barge materials on the Great Lakes. Funded in part through the U.S. Department of Transportation's Maritime Administration's Small Shipyard Grant Program with the City of Alpena, the dock improvements will accommodate larger vessels, which will lead to fewer trips to transport goods and a reduction in CO2 emissions from Lakes transportation.
"As Holcim is showing in Alpena, the path to net-zero carbon emissions requires a blend of proactive solutions," said Michael Nixon, senior vice president, manufacturing at Chicago-based Holcim US. "Whether it's using alternative fuels or implementing renewable energy from solar power, we are committed to reducing our reliance on fossil fuels—a goal that will benefit the environment as a whole and the Alpena community we have called home for more than 115 years."
The solar project's 25 MW solar array will be optimised for maximum energy yield with fixed-tilt high-performance bifacial solar panels that generate power on both the front and back sides.
NorthStar Clean Energy will implement the solar solution, which is anticipated to reduce the plant's CO2 emissions by approximately 25,000 tons annually and produce over 30 percent of its current energy demand. Holcim is expected to receive approximately 35,000 MWh of clean power from the project per year under a Solar Equipment Service Contract with a minimum term of 20 years.
Construction of the renewable energy system will begin this year. Commercial operations are expected to begin in December 2024.
