## Summary

**30% investment tax credit for hydropower improvement property.** This bill would create a new credit to fund upgrades at qualified dams to increase clean hydropower, improve grid resilience, and restore fish and river habitat. - Hydropower owners and developers would be eligible for a 30% credit for hydropower improvement property, covering upgrades like turbines, safety repairs, interconnection work, and certain progress expenses claimed before the property is placed in service. - Off-grid and small dam communities could benefit because the bill covers approved remote dams licensed by the Federal Energy Regulatory Commission before December 31, 2020 that have a maximum net output of 20 megawatts. - Projects that add or improve fish passage, enhance water quality, promote downstream sediment transport, remove obsolete river obstructions, or expand public access qualify, and tax-exempt and governmental entities can elect the credit as a payment while the credit may also be transferred or sold to raise cash.
