The law didn't require EmPOWER to continue past 2015 after meeting the energy savings goal. But the state's Public Service Commission has supported the program and asked utilities to lay out plans to invest more in energy efficiency. The bill puts the force of law behind the PSC's actions.
A report in January found that for every $1 spent in the program, the state has saved $1.81 through reduced energy prices.
A coalition of about two dozen companies —including MGM Resorts, Gaylord National and several energy companies — wrote that the EmPOWER program will help reduce electricity costs, benefiting both companies and consumers.
"A commitment to continuing EmPOWER Maryland would help give the business community the confidence to invest and grow," the companies wrote in their letter to the Republican governor.
Hogan's office did not immediately respond to a request for comment.
