SPP warns of potential rolling blackouts as 14-state grid nears shortfall

The Southwest Power Pool warned it could order rolling blackouts Monday evening as record electricity demand pushed the 14-state grid to the brink of a shortfall.

"We are operating with razor-thin reserve margins due to several unexpected plant outages," an SPP spokesperson said.

The grid operator issued a level three energy alert at about 6 p.m. EDT for its western territory, deploying some or all of its operating reserves to meet demand. SPP de-escalated the alert a couple of hours later without ordering controlled outages.

The warning shows the strain on a grid stretching from North Dakota to Louisiana as a heat wave drives consumption to record levels. On rare occasions, grid operators order controlled blackouts to prevent cascading failures across a wider area.

The near-miss signals that the central US grid faces mounting pressure as extreme weather and rising power demand test infrastructure capacity. Investors will watch for any regulatory response or capacity additions in the SPP region following the alert.
