Interconnection: Overview of Components

Two Primary Components of the Term “Interconnection” (“Interconnection” = “Point of Receipt” + “Pipeline Extension”)

“Point of Receipt (POR)”

Customer Pipeline Utility Pipeline

RNG from biogas conditioning “Pipeline Extension” upgrading plant (cost is site specific)

Interconnection Facilities are Funded by Interconnector and Owned/Operated by SoCalGas

Three Projects are Currently Injecting RNG into a CA Utility Pipeline With Many More Under Development

1. Point Loma Wastewater Treatment Plant (Point Loma CA)

• Capturing more than 1.3 MMcfd of digester gas

• Injecting since 2012 into utility pipeline

• Total project cost of $45 million

2. CR&R Waste and Recycling Services (Perris CA)

Two of the four phases are complete with each phase capable of handling ~83K tons/year of organic waste (~1M DGE/yr of vehicle fuel)

Green/food waste (previously sent to a landfill) is converted to produce fertilizer, soil amendment and RNG

Injecting since mid-2018, into SoCalGas pipeline

Over $100 million total project cost at full buildout

First RNG-to-pipeline project in SoCalGas’ service territory

CR&R - Perris

Three Projects are Currently Injecting RNG into a CA Utility Pipeline With Many More Under Development

3. Calgren Dairy Fuels (Pixley CA)

First dairy digester pipeline cluster project in California and started injecting RNG into SoCalGas’ pipeline in February, 2019

Plan to collect biogas from anaerobic digesters at 12 Tulare County dairies by the end of 2019

The facility will capture the methane produced from more than 75,000 cows

SoCalGas will be capable of adding up to 2.26 Calgren Dairy Fuels billion cubic feet of RNG each year to its pipeline system
