Hull Street Energy is currently at the center of the largest hydroelectric transaction in Michigan’s history. Understanding their strategy is essential if you are looking to enter this space, as they have effectively written the “playbook” for private equity ownership of these assets.

Hull Street Energy is currently at the center of the largest hydroelectric transaction in Michigan’s history. Understanding their strategy is essential if you are looking to enter this space, as they have effectively written the “playbook” for private equity ownership of these assets.

​The “Confluence Hydro” Playbook

​In late 2025, Hull Street Energy formed a subsidiary called Confluence Hydro specifically to acquire 13 hydroelectric dams from Consumers Energy. This deal is expected to close in 2026 pending regulatory approval from the MPSC and FERC.

​How the Deal is Structured (The “70/30” Real Estate Parallel)

​Hull Street isn’t just “buying a dam”; they are executing a classic Value-Add infrastructure play:

1. ​Low Acquisition Cost: They are reportedly acquiring the dams for a nominal price (reportedly as low as $1 per dam) because the assets are over 100 years old and carry massive maintenance liabilities.
2. ​Guaranteed Revenue: To make the deal viable, Consumers Energy has agreed to a 30-year Power Purchase Agreement (PPA). They will buy the power at a premium rate to ensure Hull Street has the cash flow to repair and modernize the dams.
3. ​Modernization: Hull Street will deploy its own private equity capital to upgrade turbines and safety structures, extending the life of the assets past their 2034 license expirations.

​The Risks Hull Street is Managing

​If you were to crowdfund a similar project, your Risks & Disclosures would need to address the same “Red Flags” that critics have raised about the Hull Street deal:

• ​The “Flip” Risk: Private equity firms typically have a 5- to 7-year horizon. Critics point out that Hull Street has previously acquired dam portfolios and sold them within three years. This “liquidity risk” is something your investors must understand.
• ​Maintenance vs. Profit: Unlike a utility, a private owner like Hull Street (or your corporation) doesn’t have “captive ratepayers” to cover cost overruns. Every dollar spent on a crumbling concrete spillway is a dollar taken directly out of the 70/30 split.
• ​The “Edenville” Factor: Michigan is highly sensitive to dam safety after the 2020 failures. A private owner must maintain massive Environmental & Liability Insurance, which can be a significant “leakage” in your pro-forma.

​Can You Copy This Model?

​While the “13 Dams” are spoken for, you can apply this same logic to Micro-Hydro or Retired Mill Sites in Michigan:

1. ​Acquisition: Find a decommissioned mill or private dam (look for “Brownfield” listings).
2. ​The PPA: Negotiate a “Qualifying Facility” contract with DTE or Consumers Energy to buy your power.
3. ​The Crowdfund: Use the 70/30 model to raise the “CapEx” (Capital Expenditure) needed to install modern, high-efficiency turbines.

​Current Market Status (January 2026)

• ​The Big Deal: The Consumers/Hull Street transfer is currently in the “Regulatory Review” phase.
• ​The Opportunity: Smaller dams (under 5MW) are often overlooked by big firms like Hull Street, leaving a “Blue Ocean” for smaller private corporations and crowdfunding groups.
