A plane crash into high-voltage transmission lines stressed California's power grid Tuesday as inland areas sizzled in a summer heat wave that raised public health and fire worries. The crash into the San Diego-area electrical lines and an apparently unrelated loss of 1,900 megawatts of generation from several Southern California power plants led operators of the state's power grid to call for statewide conservation into the evening hours.
