ConEdison & PG&E/Marin – InteroperabilityJames McCray – COO/CMONovember 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 Use ConEdison/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 - MarinSpot 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

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 61850 – Substations and Renewables Management– National Standards - NIST, GridWise, et.al. Configurations
