Why is SDG&E Involved in Transportation Electrification?

• SDG&E has a well-established track record in utility infrastructure development, management, and operations

• SDG&E is already a key partner in local, regional, and state efforts to reduce greenhouse gas emissions

• Given the market for EV charging infrastructure has not proliferated, we can help stimulate the market by making the initial investments

• Power generation accounts for less than 20% of the state’s GHG emissions, whereas transportation accounts for about 40%

VGI Rate

5

• Rate to driver

• Hourly dynamic pricing

• No demand charge

• Cost: Energy (kWh) + adder for top 150 system and 200 circuit hours

• Rate incentivizes charging during low demand periods

Charging App

6

• User friendly app

• Multiple options

• Set it and forget it

7

• 253 Charging stations

• 434 Employees drive electric

• 23 SDG&E non-public sites

Build it and they will come

More employees than chargers

Lessons Learned

8

• People respond to price signals

• Install charging stations where each charger can be accessed by multiple vehicles
