Private equity firms have made their mark on everything from healthcare to housing, often delivering big returns for investors while leaving consumers with mixed results. Now they’re setting their sights on America’s utility companies, and BlackRock’s proposed takeover of Minnesota Power’s parent company could be the defining test case.
The world’s biggest asset manager, together with the Canada Pension Plan Investment Board, is seeking to acquire Allete, the publicly traded utility that owns Minnesota Power and has over 150,000 customers in northern Minnesota. But the transaction has ignited intense resistance from consumer groups, whereas it has gained favor from labor unions and environmentalists.
Judge Slams Proposed Allete Deal, Citing Risks to Minnesota Power Customers and Clean Energy Goals
Administrative law judge Megan J. McKenzie delivered a scathing assessment of the proposed deal in July, recommending that Minnesota regulators reject it entirely. Her lengthy report warned that private equity ownership could weaken Minnesota Power’s finances, jeopardize the state’s ambitious clean energy goals, and ultimately stick customers with higher bills and less reliable service.
BlackRock and its allies retaliated in August, describing the judge’s report as inaccurate and one-sided. The exchange is hot because the stakes are high, as the Minnesota Public Utilities Commission is about to make its ultimate ruling.

Under the proposed deal, BlackRock-controlled Global Infrastructure Partners would own 60% of Allete, with the Canadian pension board holding the remaining 40%. The commission has the power to block utility mergers in Minnesota.
How Private Equity’s Approach to Utilities Could Harm Customers
Critics worry that private equity’s traditional approach of streamlining operations to maximize returns could be disastrous for utility customers. Karlee Weinmann from the Energy and Policy Institute describes the industry as “a very extractive actor in the marketplace” that focuses on cutting costs and boosting profits.
“We know that the playbook is to quote-unquote streamline these companies, so this is a fearsome prospect for workers and consumers,” Weinmann said.
The concern isn’t just theoretical. Douglas Jester, an energy analyst who studied Michigan’s Upper Peninsula Power Company after its private equity buyout, found that the utility sought rate increases almost immediately after the deal closed, citing unexpected costs that hadn’t been fully disclosed during the approval process.
But supporters argue that Minnesota Power actually needs private capital to meet Minnesota’s aggressive climate goals. The state requires all utilities to generate 100% carbon-free electricity by 2040, which means massive investments in renewable energy, batteries, and transmission lines.
“Advancing the clean-energy future requires significant investment, and the long-term, experienced investors we have chosen as partners will give us the access to capital needed for this energy transition,” Minnesota Power spokesperson Amy Rutledge explained.
Clean energy advocacy group Fresh Energy agrees, arguing that the merger would actually reduce risks to Minnesota’s climate transition, especially after federal renewable energy incentives were scaled back under the Trump administration.
BlackRock’s ‘Golden Age’ of Infrastructure
There’s another factor driving private equity interest in utilities: the explosive growth of artificial intelligence and data centers. These facilities consume enormous amounts of electricity, and their energy needs could nearly triple by 2028 according to federal estimates.
Brian Edstrom from the Citizens Utility Board of Minnesota sees this as the real opportunity BlackRock is chasing. Energy-guzzling data centers are “a generational opportunity for well-capitalized infrastructure investors,” he said.
BlackRock CEO Larry Fink appeared to validate this approach in a recent CNBC interview, labeling infrastructure investments a “golden age” opportunity, especially where AI, data centers, and energy converge.
A July settlement between Minnesota Power and the Minnesota Department of Commerce might offer the way forward. Under the agreement, rate hikes would be avoided until 2025, the company’s profit margins would be lower by a fraction, the new owners would have to spend $5 billion on clean energy infrastructure and shell out $50 million for advanced battery technology, and financial penalties for losses in service quality would be enforced, as well as enhanced protections for workers.
Whether this deal will be acceptable to regulators is still unknown. The ultimate ruling could be a significant precedent as other private equity operators look to acquire utilities nationwide, pushing the limits of whether profit-driven methods can be reconciled with sound, affordable public service.
