History of Rapid Earth Fault Current Limiter (REFCL) in Australia 2009 Black Saturday fires in Victoria, Australia o Burned 1.1 million acres, left 180 people dead, and 414 people injured The government performed over 2,000 separate tests to determine what causes electrical ignition events o Con
Slide 8: EPIC 3.15 Objective
EPIC 3.15 Objective Objective Evaluate methods for rapidly reducing the flow of current and risk of ignition in single phase to ground faults, through the demonstration of REFCL technology at a PG&E substation Net New REFCL technology is relatively new to the world, with application for mitigati
Slide 9: REFCL – Electrical Fire Risk Reduction
REFCL – Electrical Fire Risk Reduction What is REFCL Technology? • Consists of an inductor tuned to the network capacitance installed between the substation transformer neutral and ground o A controller and an inverter supplement the functionality of the inductor o Other terms for this setup are res

Slide 14: EPIC 3.29 Advanced Customer Bill Scenario Calculator
EPIC 3.29 Advanced Customer Bill Scenario Calculator Henry Vuong November 9, 2018 14
Slide 15: Background
Background • As DER penetration continues to increase, more customers will become increasingly engaged and want to optimize their bills • Current tools • Multiple stand-alone, single purpose tools • Targeted towards mass-market, allow simple rate analyses
Slide 16: Objectives
Objectives • Create an online tool for customers to more easily understand how behavioral changes and technology investments affect their bills • The tool would highlight financial and environmental advantages of the different technologies to promote understanding and adoption of DERs • Leverage too
Slide 17: Current Calculators
Current Calculators Solar Electric Vehicle Rate Comparisons Pros: Pros: Pros: • Customizable system • Basic customizations • Provides personalized size, # of panels, savings • Easy to follow rate comparisons based target etc. • Provides comparisons on actual historical • Interactive and simple with
Slide 18: Scenario Analysis Tool
Scenario Analysis Tool We want a tool that can: • Run analysis based on actual customer usage • Perform What-If analysis with one or more DER • Allow more advanced customizations such as targeted load shifting/load reduction • Provide rate analysis and rate recommendations based on selections • Be i
Slide 19: Track Customer Engagement
Track Customer Engagement Based on engagement & selections: • We can better understand geographically where customers are more interested in solar, EV’s, storage etc. • Tailor and target communication and outreach • Enhance distribution planning • Identify strategic locations for EV charging station
Slide 20: Other Positive Outcomes
Other Positive Outcomes The online tool can: • Increase overall awareness of various rate options • Make customers aware of their options and the potential return on their investments • Help customers in Disadvantaged Communities (DACs) understand their options to save energy and money and eligible
