ConEdison & PG&E/Marin – Interoperability James McCray – COO/CMO November 13 Grid-Interop T&D Session

Today’s Discussion Current Projects Network Designs What our Utility Partners are saying Integration and Interoperability Expectations Field Experiences – ConEdison – PG&E Future Vision

Infotility – Current Projects PG&E / Marin Renewables – Mixed UseConEdison/Innoventive – Verizon Data Centers Boulder – Eco-Community ConEdison – Urban Microgrid

Marin County Civic Center Collaborating with the Marin County Sustainability Office on using the Civic Center Campus, and near-by municipal facilities for early stage demonstrations. – PV already installed – Access to EMS systems with capabilities to embed GA intelligence. – Potential DR with lights and HVAC – Nearby schools, water district, and theater appear to be on the same PG&E feeder – Politically attractive site for Marin in illustrate what they are doing in this area.

Spot Networks and Radial Feeders Radial Feeder - Marin Spot Network - NYC

Expectations Everything Magically Links Together – Smart Metering/AMI – Renewables Availability and Performance – Storage – SCADA Transformer Loading and Temperature – Other Grid Conditions – Demand Response – Local Contingencies and Emergencies – Market Pricing – Market and Local Curtailment Signals

The Reality - The Interoperability Void SCADA AMI DR DER VOID

Preliminary Metering Plan

Field Experiences – Growing Pains ConEdison – 3G System of the Future – Recently Installed Transformer Monitoring – System Wide – Demand Response – Totally Manual – AMI – Initial Pilots and Meter Testing PG&E – Distribution Operators and Demand Response – Web-based Transformer and Network Loading – Most Substations – Demand Response – Siloed Systems – AMI – Initial Installations, New Systems Marin – Sustainable Community – Massive Influx of Renewables – No Performance Visibility – Major Storm Reliability Issues – Renegade Islanding – Community Based Management of Energy Supply – No Systems

Future Vision – Customer Experience Interoperability is an evolutionary process. Start out small, with custom interfaces. Build and implement software applications with – Open interfaces with limited or no proprietary constraints. – Consistent with current understanding of UCA, IEC 61850, etc. Longer-term evolution of field test and production implementations as standards are completed and accepted. – IEC – Substations and Renewables Management – National Standards - NIST, GridWise, et.al.
