NEW YORK—The largest U.S. power-grid operator is probing why suppliers were unable to deliver needed power during a late December storm when customers narrowly avoided outages as freezing temperatures descended, officials said on Thursday.

Generators that were unable to deliver increased electricity during three peak demand days in late December could face about $2 billion in penalties, stakeholders and analysts said.
