Earlier in 2012, the shareholder advocacy group As You Sow filed a resolution asking Duke Energy to prepare a plan to reduce exposure to the costs and risks associated with continued reliance on coal.
The resolution also asks Duke to report back to shareholders at the utility's annual meeting on May 3 regarding the progress that has been made in meeting the risk-reduction goals in the plan.
Investors will also vote on the resolution at this time. Once Duke's merger with Progress Energy is completed, the company will depend on coal for 42 percent of its generating capacity.
