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.
