CPUC Issues Decision on Wireline Provider Resiliency Strategies

February 25, 2021

The California Public Utilities Commission (CPUC) issued a decision on February 18 adopting wireline provider resiliency strategies. The decision (21-02-029) requires California’s facilities-based wireline providers to develop comprehensive resiliency strategies to prepare for catastrophic disasters and power outages. These requirements are for wireline facilities in Tier 2 and Tier 3 High Fire Threat Districts (HFTDs). The decision: 

  • Defines resiliency, in the context of emergency services management by the wireline providers, as the ability to recover from or adjust to adversity or change through an array of strategies.
  • Adopts a 72-hour backup power requirement for the wireline providers’ facilities in Tier 2 and Tier 3 HFTDs providing service.
  • Requires the wireline providers to file Communications Resiliency Plans with the CPUC’s Communications Division that detail their ability to maintain a minimum level of service during a disaster or an electric power grid outage.
  • Permits the near-term use of diesel generation as a primary backup power resource but directs the wireline providers to explore ways to transition to renewable generation for backup power.
  • Directs the wireline providers to submit annual emergency operations plans.
