In December 2019, the CPUC implemented an Incentive Reservation System for the Biomethane Injection Monetary Incentive Program (BIMIP) established in Decision 15-06-029. The BIMIP provides up to $3 million for non-dairy clusters and $5 million for dairy clusters that successfully interconnect with the natural gas pipeline system and operate by December 31, 2026. The Incentive Reservation System allows project developers to reserve incentive funds during the development phase of a project and receive the funds once the project is interconnected and operating. Applications for the Incentive Reservation System are designed to ensure that only viable projects can secure a spot on the reservation list.
