Two Maryland senators have outlined some of their plans to explore returning to a regulated electricity market in Maryland. Senator E.J. Pipkin, a Republican from the upper Eastern Shore, and Senator Jim Rosapepe, a Prince George’s County Democrat, are sponsoring the Maryland Electricity Reregulation and Energy Independence Act of 2009. They say almost ten years after deregulation, competitive retail electricity markets have not developed as planned. The Maryland Public Service Commission has recommended against full re-regulation. The PSC says the high cost of buying back infrastructure creates too many uncertainties about how beneficial re-regulation would be.
