Program Overview

Pursuant to Public Utilities Code section 281, moneys in the California Advanced Services Fund (CASF) Broadband Infrastructure Grant Account (Infrastructure Account) are available to the Commission to award grants to subsidize the cost of middle-mile and last-mile infrastructure to expand the State’s broadband network. The program's goal is to encourage deployment of high-quality advanced communications services to all Californians that will promote economic growth, job creation, and the substantial social benefits of advanced information and communications technologies. The Commission is required to give preference to programs and projects in communities with demonstrated low broadband access and in communities facing socioeconomic barriers to broadband access.

Program Updates

    On November 18, 2022, the CPUC issued Decision (D.) 22-11-023 modifying CASF requirements and guidelines for the Broadband Infrastructure Grant Account.


    On July 20, 2021, Governor Newsom signed Senate Bill (SB) 156. The relevant changes to the Broadband Infrastructure Grant Account are as follows:

    • "Unserved area" changed to an area where no facility-based broadband provider serves households (or areas) at a minimum speed of at least 25 mbps downstream and 3 mpbs  upstream (previously 6 mbps/1 mbps). See Public Utilities Code Section 281(b)(1)(B)(ii)(I)
    • Projects funded by the CASF program must deploy infrastructure capable of providing broadband access at speeds of a minimum of 100 mbps downstream and 20 mbps upstream, or the most current broadband definition speed set by the Federal Communications Commission (previously 10 mbps/1 mbps). See Public Utilities Code Section 281(f)(5).
    • All grantees 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 basis. See Public Utilities Code Section 281(l)(1-2).

    These changes became effective on July 20, 2021.
