CASF Broadband Infrastructure Grant Account supports broadband providers and local agencies in building middle-mile and last-mile networks to expand internet access in unserved California areas.
CPUC removed the requirement to also submit applications to the Public Advocates Office at Cal_Advocates-CASF-Apps@cpuc.ca.gov.

The California Advanced Services Fund (CASF) Broadband Infrastructure Grant Account is administered by the California Public Utilities Commission (CPUC) under Public Utilities Code section 281. It subsidizes infrastructure deployment to extend California’s broadband network into unserved areas, where no fixed facility-based provider offers service at least 25 Mbps downstream and 3 Mbps upstream.
Projects may use wireline or wireless technology and must deliver at least 100 Mbps downstream and 20 Mbps upstream, or the current FCC standard if higher. Middle-mile funding must support last-mile serviceable locations. The program prioritizes areas with no connectivity or very slow service, followed by low-income areas. Its broader goals include economic growth, job creation, and access to the social benefits of advanced communications.
