As utilities generate more electricity from natural gas, the potential is emerging for freak weather or other events to cause problems for both delivery systems and create a cascading regional disaster.
That was the conclusioon industry officials and regulators reached after a "stress test scenario" played out in Washington, D.C.
Planning to avoid such events, in which problems in the gas system aggravate problems in the electric system and vice-versa, is complicated by the two energy systems' significantly different regulatory structures, officials said.
