8. Investment and building generation capacity added reliability to the system. On hot days, electricity demand in the ERCOT area can threaten to overload both generators and transmission lines, blacking out large areas of the state. An example of this occurred on April 18, 2006; rolling blackouts affected much of southeast Texas. Additional generators provide back up against system shortfalls.
