Utility Transformation Opportunity
Utilities are at a crossroads…..
According to the DOE Grid 2030 report, in the next 20 years,
the U.S. will spend $450B on electric infrastructure,
just to meet load growth

Advanced Meters Provide Near-term
Options for Texas Consumers
• Real-time pricing will encourage consumers to
monitor and adjust their use.
• Consumers can participate in demand response
programs to reduce peak demand.
• Advanced meters can automate functions for
utilities, such as meter reading and thermostat
cycling programs.
• Pilot program in the Pacific NW garnered
average 10% savings for customers.
• CenterPoint and Oncor Electric have filed
advanced meter deployment plans.
New Systems Required
• Real-time data
management from multiple
AMI systems & sources
• Manage AMI service
levels to required
standards
• Validate real-time data
• Integrate real-time AMI
services with
enterprise applications
• A repository for usage

Providers Requirements
• Retailer consolidated billing – TDSPs don’t bill individual consumers
• TDSP tariffs based on total consumption and some demand
charges
• Retail Energy Providers (REPs) bill consumers based on:
– Non-tariff retail programs and service offerings
– Regulated distribution charges (incl metering charge)
• TDSPs will be required to deliver:
– Register readings
– Interval Data (15 minute)
– Support disconnection & reconnection services

There are three electric grids in the U.S.
• Eastern Interconnection
• Western Interconnection
• Electric Reliability Council of Texas (ERCOT)
AMS is a New Paradigm Which
Requires a Different Mindset &
Enables a New Approach to the Texas Market

• Communication from meter is down
• Computer system problem

Push down data stack – no data overwritten or deleted
• Old data is available
• All updates are date / time stamped
• Extract report data by ESID
– For a given period (Tuesday )
– For all database updates after mm/dd/yy:hh.mm
Quality Meter Reading Data
Bottom Line: When you have a read, 99.x% of
the time, it will be final settlement quality read.
In the rare instance when the read is revised, you
will have a record of the change, the reason, the
date and time the record changed for a given
time slot.
•
Estimated for billing window (DB updated 3/12/2008 12:36:02)
•
Actual read received DB updated 3/14/2008 10:34:52)
•
Revised due to diversion (DB updated 5/12/2008 18:55:35)
Recommended TX Solution
• Texas common data repository and web portal
• Provide 15 minute interval data for all
stakeholders (REPs, consumers, ERCOT, Third
Parties, TDSPs)
• Variable APIs for TDSPs transport to Host
• Open architecture to support future market
design (or incorporate other transactions)
