Maryland became the 10th state to adopt the Advanced Clean Trucks rule, which sets targets for the delivery of zero-emissions medium- and heavy-duty vehicles that gradually increase every year.

In addition to the POWER Act, Maryland also approved bills aimed at growing markets for energy storage, community solar and zero-emission heavy-duty trucks.

The Maryland legislature passed legislation raising the state's offshore wind target to 8.5 GW while calling for coordinated transmission planning with PJM.
