Relicensing is a complex process in which private dams are re-evaluated every 30 to 50 years. The Federal Energy Regulatory Committee "considers anew whether it is appropriate to commit the public's river resources for private power generation FERC is now required, when deciding whether to issue a license, to consider not only the power generation potential of a river, but also to give equal consideration to energy conservation, protection of fish and wildlife, protection of recreational opportunities, and preservation of other aspects of environmental quality." Relicensing was infrequent until 1993, when hundreds of licenses began to expire. "The Hydropower Reform Coalition formed in 1992 to take advantage of this once-in-a-lifetime opportunity to restore river ecosystems through the relicensing process." To the Coalition's dismay, a new bill is being considered called the Hydroelectric Licensing Process Improvement Act, which if passed, "would limit the abilities of federal agencies to protect natural resources," making relicensing easier for dam operators.
