Drivers for SCE’s Emerging Technologies Work

• State and federal mandates for GHG reduction, energy efficiency,demand response, and renewable energy integration.

• Customer expectations for superior reliability and power quality at a reasonable cost.

• Interaction between emerging technologies to help control power delivery in an efficient, safe and reliable real-time mode.

• Development of smart transmission and substation technology solutions because of PMU technology.

• The increased speed, intelligence and computation of real-time monitoring equipment.

Types of Electric Vehicles (EVs)• Hybrids (EV)

– Ford Escape, Prius, etc.• 10 – 20 miles equivalent EV range• Blend electric-only and hybrid operation• Engine is often on, but mpg can be 100+ for

urban driving

• Plug-In Electric Vehicles (PEVs)– Nissan, Tesla, Mitsubishi, Subaru

• 100 – 200 mile EV range• Large battery, high charge power• There is no engine – home-based and public

charging of the batteries is needed

• Extended Range EV (EREV) – Chevy Volt

• 20 – 40 miles of EV range• Distinct electric-only operation until battery is

depleted• Engine is rarely on – even on the freeway except

on longer trips
