The budget category for SoCalGas' low income and disadvantaged communities customer (DAC) class is oversubscribed. The remaining balance of funds will be allocated to those multifamily and single family low income and DAC applications in the order that they were submitted for review.

At this time, it is not known if any additional funds will be available. Applicants can either be placed on a waitlist, which does not guarantee that any additional low income or DAC funds will be available, or they can submit to the lower single family general market rate. Once the balances for step 1 for single family general market funds or the multifamily general market funds are exhausted, they will each drop to step 2 accordingly. Please note that the step 2 allocation budget for single family general market is $710,000 at the incentive rate of $25.37/therm with the potential maximum incentive that could be received of $3,710.

The step 2 allocation budget for multifamily general market is $2,530,000 at the incentive rate of $17.16/therm with the potential maximum that could be received $800,000 per project site.
