US Grid Operator Warns of Blackouts Due to Extreme Demand
21 Jul
Summary
- Grid operator warned of potential rolling blackouts due to record demand.
- Several power plants unexpectedly went offline, reducing power reserves.
- A level three energy alert was issued but later reduced.
The regional U.S. grid operator for 14 central states issued a warning on Monday evening, indicating the potential for rolling blackouts. The power system was facing an electricity shortfall due to record demand, exacerbated by several unexpected power plant outages. These events significantly reduced reserve margins at a critical time.
The operator, known as the Southwest Power Pool (SPP), declared a level three energy alert, signifying the use of operating reserves to meet demand. While the grid operator managed to avoid ordering controlled blackouts, the situation highlighted the system's vulnerability during the heat wave. The alert was issued for SPP's western territory before the threat level was subsequently lowered.
