As of June 2014, the phone number for the Public Service Company of Oklahoma (PSO) is (888) 776-1366. PSO is a division of American Electric Power (AEP), a company that supports community efforts to save energy.
PSO is a public initiative to help home owners create more efficient homes. It achieves this goal by providing monetary incentives for people to upgrade certain parts of their homes, including adding new insulation, solar screens and duct replacement. Homeowners must choose from a list of approved contractors. It also provides free weatherization to low-income families. PSO will come evaluate the home to assess what types of efficiency upgrades, including weather stripping and attic insulation, it qualifies for. Weatherization can help lower electric bills, as it helps keep cool air from escaping in the summer and warm air from escaping in the winter.
