13

Regulated rate of return

• Regulated price for customers

• Approved through “rate case”

• Based on utility’s cost plus reasonable profit margin

“Captive” customer base

Multiple control areas with limited power flows between utilities

Basic characteristics

Vertically Integrated Utilities – Structure

14

Allowed for wholesale deregulation

Opened the doors to competitive wholesale producers

Ensured open access to transmission system

Texas Legislature amended the Public Utility Regulatory Act (PURA)

Called for “the establishment of a fully competitive electric power industry”

Ordered functional unbundling of Investor-Owned Utilities

• Generation companies sell into the competitive wholesale market

• Retail Electric Providers buy wholesale power and re-sell to retail customers

• Transmission and Distribution companies move power from generation to customer and remain regulated

Texas Legislature passed Senate Bill 7 (SB7)

Late 1990s – Restructuring

17

Retail Market Changes

• Retail Electric Providers responsible for customer interaction

• Retail customers allowed to choose between competing providers

System Operational Changes

• ERCOT responsible for transmission grid operations

• Establishment of single control area

Not all Utilities were investor-owned

• Municipally Owned Utilities• Electric Cooperatives

Exempt from unbundling

Can choose to opt-in to Retail Deregulation

Not all Utilities were required to unbundle


Munis and Co-ops who choose not to opt-in are called Non-Opt-In Entities, or NOIEs

20

Outside of ERCOT footprint

• El Paso Electric• SWEPCO• Xcel Energy• Entergy Texas

Some investor owned utilities did not have to unbundle


21

So, what areas have Retail Competition?

22

Price to Beat

Renewable Portfolio Standard

Governance for ERCOT

Other provisions of Senate Bill 7


23

Residential and small commercial customers only

Six percent lower than rates on January 1, 1999.

Requirement expired January 1, 2007

To foster competition, the affiliated REP of each Investor-Owned Utility had to offer a “Price-to-Beat”

Price to Beat

24

Set targets for installed renewable generation capacity

Established Renewable Energy Credits (REC) program

Required Retail Electric Providers to purchase RECs

SB7 established mandates for renewable generation

Renewable Portfolio Standard

Impacts of Advanced Meter Technology on the Retail Market


Overview

Meter Technologies

108

Measuring electrical usage

Meter – A device that measures electrical usage over a period of time.

109

Meter Technologies

Non-AMS Meters

• Scalar/Analog **• Interval Data Recorder (IDR) Meters **• Non-IDR meters **

* “Standard” meter as defined in TDSP Tariffs (PUCT §25.214)** “Non-Standard” meter as defined in TDSP Tariffs (PUCT §25.214)

Advanced Meter System (AMS) Meters

• AMSR – remote (R) connectivity *• AMSM – manual (M) connectivity **

110

Usage is recorded in 15 minute intervals (96 intervals per 24 hrs)

Data is already shaped for 15 minute Wholesale Settlement

Remote capabilities

• AMSR (≤ 200 amp)

− Remote / automatic reading− Remote connect / disconnect

• AMSM

− Remote / automatic reading− Manual connect / disconnect

Advanced Meter System (AMS) Meter Characteristics

Meter Technologies

Also known as a “Smart Meter”

111

Usage is measured in15-minute intervals (96 intervals per 24 hrs)

Data is already shaped for 15 minute Wholesale Settlement

Typically reported monthly through 867 transactions

Predominantly installed on large customers > 700 kW/kVA demand

May require manual field activities

Interval Data Recorder (IDR) Meter Characteristics

Meter Technologies

ERCOT Settles the Real-time Wholesale Market in 15-minute intervals

112

Known as a “Traditional” Meter

Usage is a scalar measurement for an entire month

Data must be shaped for 15 minute Wholesale Settlement

Requires manual field activities

Non-IDR/Scalar/Analog Meter Characteristics
