DTE Energy (NYSE:DTE) has initiated a request for proposals (RFP) for 1,000 megawatts of new wind and solar generation capacity in Michigan, setting a tight timeline for developers to deliver power by the end of 2029. The Detroit-based utility announced the solicitation as part of its broader CleanVision Integrated Resource Plan, which aims to significantly reshape its generation portfolio over the next decade.
Michigan's energy legislation, enacted in 2023, mandates that electric providers achieve a 50% renewable energy standard by 2030, increasing to 60% by 2035. Additionally, a separate clean energy rule requires 80% renewables by 2035 and a full 100% by 2040, according to the Michigan Public Service Commission. DTE's RFP is a direct response to these regulatory targets, as the utility accelerates its transition away from fossil fuels.
Under its current integrated resource plan, which has received regulatory approval, DTE plans to retire all coal-fired generation by 2032. To replace that capacity, the utility aims to add 5,400 megawatts of solar and wind power along with 780 megawatts of energy storage by that same year. The new RFP specifically targets projects that will connect to either the Midcontinent Independent System Operator (MISO) grid or DTE's own distribution system.
DTE has scheduled a virtual pre-RFP conference for May 26, with final bid submissions due by August 13. The company expects to finalize contracts during the first quarter of 2027. The utility currently generates enough wind and solar energy to power over 900,000 homes and plans to expand that capacity to serve approximately 6 million homes by 2042, as reported by pv magazine USA.
In addition to wind and solar, DTE is also advancing its energy storage capabilities. Last month, the company launched a separate RFP for up to 480 megawatts of standalone storage projects in Michigan, with an anticipated start date in the first quarter of 2029. DTE's long-term target includes 2,950 megawatts of storage capacity by 2042.
The competitive landscape is heating up, as nearby utility Consumers Energy recently brought its 250-megawatt Muskegon Solar project online in January. Sri Maddipati, president of electric supply at Consumers, noted that the project demonstrates the utility's ability to build reliable and cost-effective renewable projects for its customers. Consumers Energy is a subsidiary of CMS Energy (NYSE:CMS).
DTE's push for clean energy is underpinned by reliability considerations and a commitment to reducing emissions. “Providing safe, reliable and affordable energy to our customers is our highest priority,” said Joi Harris, DTE's president and CEO, during the company's April earnings call. Harris emphasized the utility's focus on modernizing infrastructure and expanding clean energy resources.
However, the 2029 timeline is not without obstacles. Local opposition remains a significant hurdle, as evidenced by Ingersoll Township's recent denial of a special-use permit for DTE's proposed Poseyville Solar Park. DTE is currently evaluating its next steps. Under Michigan's Public Act 233, the state commission has the authority to approve large renewable projects even when local municipalities object, providing a potential path forward for developers facing community resistance.
Industry analysts note that the tight deadline could pressure developers to move quickly on permitting and construction, while also potentially driving up costs. The RFP's outcome will be closely watched as a bellwether for Michigan's renewable energy ambitions and the broader transition in the Midwest power market.
