Only five of 99 nuclear units remain offline

As of early May 26, only five of the nation’s 99 nuclear power units were not generating power, another sign that the annual spring refueling and maintenance season is winding down.

Some units in the Northeast that had been undergoing refueling outages, and one that had been offline due to a transformer fire, have returned to service following the long Memorial Day weekend.

The FirstEnergy (NYSE:FE) Beaver Valley 1 facility in Pennsylvania was listed at 86% early May 26, according to Nuclear Regulatory Commission (NRC) data. As recently as May 24, the unit was listed at zero generation.

Beaver Valley had only started its refueling and maintenance outage on April 25, according to GenerationHub data.

Likewise, the Entergy (NYSE:ETR) Pilgrim 1 facility in Massachusetts was listed at 98% on May 26. It had gone into a refueling and maintenance outage on April 19. The PPL (NYSE:PPL) Susquehanna 2 facility in Pennsylvania was listed at 38% generation May 28. It had been listed at zero generation as recently as May 23. Susquehanna 2 had started its refueling outage on April 10.

In addition, the Entergy Indian Point 3 nuclear facility in Buchanan, N.Y., is back in service after being offline since a May 9 transformer fire, an incident which saw a significant amount of fluid leak into the Hudson River.

It appears that the only reactors remaining out of service include the Duke Energy (NYSE:DUK) Robinson 2 unit in South Carolina; the Dominion (NYSE:D) Surry 1 in Virginia; the Xcel Energy (NYSE:XEL) Monticello plant in Minnesota; the Energy Northwest Columbia Generating Station in Washington; and the Omaha Public Power District (OPPD) Fort Calhoun nuclear plant in Nebraska remain offline
