The recent heat wave has pushed state electricity demand to record levels, but officials said Texans shouldn't fear a repeat of April's rolling blackouts.

"We are prepared for hot temperatures and high demand in the summer," said Dottie Roark, spokeswoman for Electric Reliability Council of Texas, which oversees the power grid for most of Texas. "We don't expect any problems."

Electrical demand is at all-time highs, with last Monday's peak-hour electrical demand breaking all records for July. Then Tuesday and Wednesday each broke the previous day's record. Temperatures again surpassed 100 degrees Thursday across much of Texas, but Wednesday's record was not broken.

The blazing heat is expected to effect the state for at least the next 10 days, prompting the Texas Department of State Health Services to warn people to cool their homes and seek air-conditioned public places.
