## Summary

Amends the Environmental Protection Act. In a provision establishing greenhouse gas emission controls, authorizes an electric generating unit or large GHG-emitting unit to continue operating if an emergency, pre-emergency, or conservative operations situation exists. Provides that no variance, adjusted standard, or other regulatory relief that is otherwise available under the Act may be granted from the Act's greenhouse gas emission controls if battery storage resources constitute at least 10% of the total State-installed generation capacity. Provides that, if battery storage resources constitute less than 10% of the total State-installed generation capacity at any time after the effective date of the amendatory Act, the Environmental Protection Agency shall delay enforcement of certain greenhouse gas emission controls. Directs the Environmental Protection Agency to adopt rules to implement these requirements. Defines "battery storage resource" and "total State-installed generation capacity". Makes other changes. Effective immediately.
