Elevating our Transmission Operations Gregg Lemler Vice President, Transmission Operations

i-PCGRID Workshop

March 27, 2014

Rapidly changing network structure requires more transmission and complicates regulatory choices.

Improved Reliability – Weather related outages alone cost the

economy between $18 and $33 billion annually. – DOE estimates all outages cost up to $125

billion Renewables Integration

– Interconnecting generation facilities timely – California’s 33% renewables by 2020

Micro-Grids – Adding operational & integration complexity

New Technologies – Storage and other technological solutions

require new approaches to integration FERC Order 1000

– Creates a competitive process for system improvements

– Requires an open planning process

Emerging Trends & Drivers

Grid Resiliency • Cost of Major Outages • Public Safety & Security • Critical Cyber Asset Protection • Geomagnetic Disturbances

Emerging Trends & Drivers Physical Vulnerability • Security Assessment • System Assessment

– Selecting critical substations • NERC Standard

STAR tool(s) and asset health indices

3 a) Ensure common language is used to describe/quantify risks

b) Escalate overlooked risks (for dev. of mitigation plans)

c) Ensure completeness of risk register

d) Confirm that final portfolio sufficiently mitigates key risks
