Senate Bill No. 373 enacted in May 1995
– Required utilities to provide non-discriminatory open access transmission to support wholesale competition in ERCOT.
– Recognized new, unregulated participants in ERCOT wholesale market.
Exempt wholesale generators
Power marketers
– Allowed non-utility wholesale market participants to offer market-based prices in ERCOT.
– Deregulated electric cooperative distribution rates.
Note: Non-ERCOT areas are subject to FERC jurisdiction for wholesale services, including transmission services.

ERCOT market restructuring legislation, Senate Bill 7, passed in 1999– Initiated competition in ERCOT retail markets beginning January 2002.– Municipally-owned utilities and electric cooperatives allowed to “opt-in”.– Included environmental and energy efficiency provisions.
• Required reduction of nitrogen oxide (NOx) emissions from older power plants by 50%, and sulfur dioxide emission from coal-fired facilities by 25%.
• Utilities required to fund energy efficiency programs equal to at least 10% of each year’s annual growth in demand.
– 1999 - 2001 – Preparation for retail competition.• Electricity rates frozen.• ERCOT develops systems required to support competition.• PUC promulgates competition rules.• PUC determines rate unbundling cases.
– July 2001 – Retail competition pilot project begins.

ERCOT: Separate Companies Provide Retail, Transmission & Distribution and Generation Services
www.aect.net (512) 474-6725

• In competitive markets, consumers have multiple retail electric providers (REPs) and service plans to choose from.
• Wholesale and retail prices are set by competitive market forces, while the PUC sets transmission and distribution rates.

Outside ERCOT: A Single Utility Provides Retail, Transmission & Distribution and Generation Services In Each Area
www.aect.net (512) 474-6725

• In fully regulated markets, the PUC sets retail rates charged to end-use customers.• Each of service area is part of a multi-state electric grid, with differing regulations. In
many cases, vertically integrated utilities purchase wholesale power from certain unregulated entities.

Key Facts on the Competitive Retail Market in ERCOT
– Price offers are substantially lower than prices available just before competition began
– Texas’ national electric price ranking has improved since the market opened in 2002
– Every competitive area in ERCOT has variable and 1-year lock offers available that are far lower than the national average price and nearly all state averages
– Among states like Texas that depend heavily on natural gas for power generation, Texas prices compare favorably, with even lower prices available to those in the competitive market

Transmission & Distribution Utilities Provide Reliable Delivery of Electricity
www.aect.net (512) 474-6725
19
Role of Transmission & Distribution Utilities
– Provide reliable delivery of electricity on a 24-7 basis.– Invest in and build infrastructure (e.g., transmission lines, Smart Grid) to support the
needs of Texas’ growing economy.– Manage their transmission networks under the direction of ERCOT; coordinating with
ERCOT on transmission planning activities.– Respond to outages (e.g., storms and disasters) that affect the grid and restore service as
quickly as safely possible.– Provide key market information, such as premise information and metering services to
facilitate successful operation of the ERCOT deregulated market.– Provide regulated transmission and distribution services to facilitate operations of
wholesale and retail business entities.
– Charge regulated delivery rates to REPs Rates based on a historical cost of service including a PUC-established return on capital
investment
Allocation of ERCOT-wide transmission costs
Non-bypassable charges include the cost to deliver electricity, System Benefit Fund, recovery of true-up costs and nuclear decommissioning expenses for existing nuclear facilities

Timeline of Transmission Line Construction
www.aect.net (512) 474-6725
20
• While certain types of generation can be constructed quickly -- often as short as 12-18 months --transmission lines typically take between three and five years. Generation can be brought into the market more rapidly if the siting takes advantage of the existing transmission infrastructure.
• Building long transmission lines can affect many landowners, often requiring a lengthy and extensive easement acquisition effort.
• The transmission line siting process must take into account the impact of those lines on environmentally sensitive and historically significant lands.
• Utility is not typically allowed to begin recovering costs until year 5 or 6.
-
Transmission Line Routing Process
www.aect.net (512) 474-6725
21
1. The utility files an application with the PUC to obtain a Certificate of Convenience and Necessity (CCN), which is assessed by the PUC
• Consideration include: the need for service; whether the route uses existing rights-of-way; parallels other rights-of-way; follows property lines; and conforms with the policy of prudent avoidance to limit overall impact of the line
2. Landowners who would be affected by a new line receive notice; landowners can informally file a protest or formally participate in the case as an intervenor
3. An administrative law judge (ALJ) holds a prehearing conference to set a schedule for the case
4. Parties to the case conduct discovery to gather facts on the case
5. An ALJ hearing is held, with cross-examination of witnesses. The ALJ and the PUC will rely on factual information submitted as evidence filed in the docket and presented during discovery
6. The ALJ makes a recommendation to the PUC, which is called a proposal for decision
7. The PUC Commissioners rule on the case and may approve it, modify it, request further action by the ALJ or deny the case. After the PUC’s ruling, parties may appeal the decision

Continued Transmission & Distribution and Generation Investment Needed Long-Term
www.aect.net (512) 474-6725
22
• According to the Texas State Data Center, 5 million new residents are expected in Texas by 2020.
• New generation must be delivered effectively and efficiently to population centers of the state.
• Though not shown here, areas of Texas located outside the ERCOT grid are also growing, both in terms of population and economic development.

The Competitive Wholesale Market in ERCOT
www.aect.net (512) 474-6725
23
Competition Has Brought Greater Efficiency to the Wholesale Market
– Generators shoulder the risk of building new power plants, bringing efficient, cost-effective generation to consumers.
– New power plants produce more electricity per unit of fuel.
– Operational efficiency of a competitive market helps push wholesale prices downward.
– The competitive market will continue to bring forward the right mix of technology and fuel type based on environmental choices by policymakers.

Strong Environmental Performance by Electric Generators in Texas
www.aect.net (512) 474-6725
28
Electric Generators in Texas Use Fuel Efficiently and Effectively Capture Emissions
– Texas is one of a minority of states with NOx, SO2 and CO2 emissions rates below the national average for electric generation
– Texas electric generators have the lowest rate of NOx emissions when compared with neighboring states
– New power plants include modern environmental emissions controls.
Maintaining Access to Cooling Water is Important to Continued Generation Reliability
– Dependable water supplies are essential to the reliable generation of electricity because most electric generation units require the use of water for system cooling.
– AECT member companies represent the largest private owners, builders, and operators of private reservoirs in Texas.

How Texas’ Steam Power Plants Use Water
www.aect.net (512) 474-6725
30
• The graphic above is a simplified example of a power plant’s use of water for steam generation.
• Most power plants heat water in a closed system until it becomes steam, then pressurize that steam to turn a generating turbine.
• The steam is then routed to a condenser, where the water is condensed and reused in the steam cycle.
