CA AB550

Allows renewable electrical generation facilities with existing incidental take permits to continue operating without additional authorization if an "at-risk species" later becomes listed as endangered, threatened, or candidate species, provided the potential listing was anticipated in the original permit

Defines "at-risk species" as species proposed for listing or those the Department of Fish and Wildlife determines may soon become candidates for listing, distinct from already-listed endangered, threatened, or candidate species

Authorizes the Department of Fish and Wildlife to partner with permit applicants to develop research projects evaluating impacts of facility siting, design, and construction on at-risk species, with approved research potentially counting toward mitigation requirements

Requires the department to report to the Legislature by January 1, 2030, on projects that included at-risk species in take authorizations, the effectiveness of the new provisions, and staff resources required for implementation

Aligns endangered species protections with California's clean energy goals, including the 100 Percent Clean Energy Act requirement for 60% renewable electricity by 2030 and 100% zero-emission retail sales by 2045
