The Pilgrim Nuclear Power Station in Plymouth went back in service late Friday night after being offline since last weekend’s powerful winter storm, according to the Nuclear Regulatory Commission.

The plant, owned by Entergy Corp. of Louisiana, originally went out of service Feb. 8 when the storm knocked out the plant’s off-site power lines. Power was restored on Sunday morning but lost again that afternoon when ice fell on a switchyard line and caused a transformer electrical fault.
