CASF Infrastructure Grant Account Requirements, Guidelines, and Applications Materials

The CASF Infrastructure Grant Account rules and requirements are set in CPUC Decision (D.) 21-03-006 issued March 2021. Specifically, see -

On July 20, 2021 Governor Newsom signed Senate Bill (SB) 156, which made the following changes to Public Utilities Code section 281. 

  • Changed the definition of "unserved area" to "an area for which there is no facility-based broadband provider offering at least one tier of broadband service at speeds of at least 25 mbps downstream, 3 mpbs upstream." See Pub. Util. Code section 281 (b)(1)(B)(ii)(I). 
  • Changed the minimum bandwidth requirements to 100 mbps downstream and 20 mbps upstream for all CASF projects. All infrastructure funded by the CASF program must meet this requirement. See Pub. Util. Code section 281 (f)(5).
  • All grantees receiving CASF funding must report licensed contractor or subcontractor expenditures in excess of $25,000 for work funded by CASF. The CPUC must post this information on a monthly bases. See Pub. Util. Code section 281 (1).

These changes became effective immediately. The CPUC is considering further changes to the CASF program rules in Rulemaking (R.) 20-08-021.  

Prospective applicants and stakeholders - please first consult your local Broadband Consortium first before contacting CASF Infrastructure Staff for information.
