Idaho Power and its customers broke their record for power demand Thursday.
Thge utility that serves 500,000 customers in southern Idaho and Oregon hit 3,245 megawatt overall peak-hour average system load. It could have been higher but it used 65 MW of its demand response programs which manage air conditioners, irrigation pumps and other uses.
Thursdy's peak tops the previous record of 3,214 MW from June 2008.
Idaho Power’s new Langley Gulch Power Plant helped satisfy the record electricity demand during this week’s triple-digit heat, including Thursday, when temperatures in Boise reached 108 degrees, its hottest day this year.
The 300-MW natural gas-fired plant near New Plymouth, Idaho, went into commercial production on June 29.
“Langley Gulch has come online at the perfect time to help us meet some of the highest loads we have seen in several years, including yesterday’s record demand” said Mark Stokes, Idaho Power’s Manger of Power Supply Planning.
