PT Scores With Energy Efficiency For the third straight year, PTISD earned an incentive check from AEP SWEPCO for energy-efficiency upgrades. Building on last year’s incentive of 37,800, this year PTISD received $12,300 from the utility for lighting, roofing, and air conditioning projects it completed in 2008. The incentive payment came as a result of the district’s continued participation in the AEP Texas SCORE (Schools Conserving Resources) Program.
