The Pennsylvania Public Utility Commission will hold a hearing May 5 at Drexel University on the use of combined heat and power (CHP), a high-efficiency method of generating electricity and thermal energy from a single fuel source.

CHP systems, which are used by businesses like hotels, universities and hospitals, generate about 2,638 megawatts or 7.2 percent of Pennsylvania's total electricity. The PUC says the technical potential for additional systems could quadruple that production.

The hearing from 1 p.m. to 4 p.m. at the A.J. Drexel Picture Gallery, in the university's Main Building at 3141 Chestnut St., will include discussions by experts, vendors and representatives of local natural gas utilities.
