LEGISLATION

New Bill Offers 30% Tax Credit for Hydro Dam Upgrades Aiming for Clean Energy Boost and River Health

This proposed legislation, the Maintaining and Enhancing Hydroelectricity and River Restoration Act, introduces a significant financial incentive for upgrading existing hydroelectric dams. Specifically, it establishes a 30% tax credit for the costs of qualifying improvements placed into service after December 31, 2022, provided they get the nod from regulators like FERC or relevant state/local bodies before January 1, 2032. The core idea is to encourage investments that boost clean energy generation while also addressing environmental concerns and dam safety.

Powering Up and Cleaning Up: What Qualifies?

So, what kind of projects get the green light for this 30% credit? The bill defines "hydropower improvement property" pretty broadly. We're talking upgrades that help fish navigate past dams (think fish ladders), improve water quality downstream, manage sediment flow better for habitats, or bring older dams up to current safety and security standards. It also covers projects that enhance public access to waterways affected by dams or even remove old, obsolete river blockages entirely. While encouraging needed upgrades is positive, the somewhat open-ended definition raises a practical question: how will regulators ensure the credit targets truly impactful environmental or energy-boosting projects, rather than just routine upkeep?

Spotlight on Remote Power

A specific part of the bill carves out support for what it calls an "approved remote dam." This targets smaller hydroelectric facilities (20 megawatts or less) licensed before the end of 2020 that are the sole power source for communities not connected to the major U.S. electrical grids (like ERCOT in Texas or the Eastern/Western Interconnections). Think isolated towns potentially in places like Alaska or remote islands. For these specific dams, adding generation capacity or making other qualifying improvements could also snag the tax credit, potentially helping stabilize power for these off-grid communities.

The Dollars and Sense: Credits or Cash?

Beyond just offering a tax credit, the bill provides flexibility in how dam owners can benefit. They can choose to take the credit directly against their taxes, or they can opt for a direct payment from the government instead. This direct pay option is key because it means even entities without a large tax liability (like certain public utilities or non-profits) could still access the funding. The credit can also be transferred or sold to another taxpayer. While this flexibility makes the incentive more accessible, it's worth remembering that tax credits and direct payments ultimately draw from public funds, meaning taxpayers broadly support the cost of these targeted investments in hydroelectric infrastructure.
