Wholesale and Retail ElectricCompetition Were Passed !With Broad, Bipartisan Support!• Senate Bill 373, which opened the wholesale electricity market in Texas, passed in 1995 when the Democrats were the majority party in the House and Senate. – The Speaker of the House and the Lieutenant Governor were both Democrats, and the bill sponsors and authors were both Democrats.• Senate Bill 7, which opened the competitive market, passed in 1999. – The Senate and the Lieutenant Governor were Republican, but the House was still majority Democrat. The House sponsor and author of the bill and the House Speaker in 1999 were both Democrats. – Senate Bill 7 passed the House with a vote of 144 Ayes and 4 Nays.• It was a bipartisan measure: 74 of the Aye votes were from Democrats, while 68 were from Republicans. – The bill passed the Senate with a vote of 28 Ayes and 3 nays. 27
Steps to Competition:! Wholesale Competition!• 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. 28!
Steps to Competition:! Retail Competition!• 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. 29!
Steps to Competition:! Transition Period!• January 2002-2006 Transition Period – “Affiliated” generators • Required to make 15% of their power available to non-affiliated retail providers • During first two years, limited to guaranteed market price for power as projected by PUC • Given incentives to install environmental clean-up equipment – Transmission and Distribution Utilities • Initial rates set using estimated/generic costs • Recovery of stranded and other transition costs authorized but delayed until 2004 True-up proceeding – Securitization bonds lower cost to customers – “Affiliated” retail electric providers • Required to lower base rates by six percent (Price to Beat) – Adjustable only for increases in natural gas prices – Price to Beat remains in place until 12-31-06 • No price competition allowed in former service area until 2005 30!
Structural Unbundling!• Incumbents required to separate business activities into the following units. – Power generation company. – Retail electric provider. – Transmission and distribution utility.• Generation and retail businesses are not regulated utilities. – Power Generation Companies must be registered with PUC. – Retail Electric Providers must be certified by PUC.• Transmission and distribution businesses remain regulated utilities.• Methods for separation of business activities. – Creation of separate non-affiliated companies. – Creation of separate affiliated companies owned by a common holding company. – Sale of assets to a third party.• Each ERCOT utility chose different models.• Code of conduct rules enforce separation requirements. 31!
ERCOT: Separate companies provideretail, transmission & distribution andgeneration services! Power Flow Financial Flow Regulated • 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. 32
ERCOT: Separate companies provideretail, transmission & distribution andgeneration services! Power Flow Financial Flow Regulated • Because wholesale electric prices are set by the competitive market, the risks associated with the cost of construction, operations and maintenance of a generation plant are borne entirely by the generator and its investors, not by end-use customers. 33
Outside ERCOT: A single companyprovides retail, transmission & distributionand generation services in each area! Power Flow Financial Flow Regulated • In fully regulated markets, the PUC sets retail rates charged to end-use customers. • Each of these service areas is part of multi-state electric grids, with differing regulations. In many cases, vertically integrated utilities purchase wholesale power from certain unregulated entities. 34
Outside ERCOT: A single companyprovides retail, transmission & distributionand generation services in each area! Power Flow Financial Flow Regulated • New power plants in these regions can be built by both regulated entities and certain unregulated entities or qualifying facilities. • Regulated utility power plants, however, must be approved by the PUC after a rigorous review of need and siting. 35
The Competitive Wholesale Market: ASuccess Story ! 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. – New power plants include modern environmental emissions controls. The competitive market is in the public interest – Operational efficiency of a competitive market helps push wholesale prices downward. – No market structure is more effective at ensuring efficient operations than a competitive one. Policy decisions should be focused on maintaining vibrant competition – Texas leaders should support policies that maintain the competitive market. – The competitive market will bring forward the right mix of technology and fuel type based on environmental choices by policymakers. 37!

Types of Generation: Beneﬁts and Challenges ! 51
Three Key Factors Affecting Choicesfor New Generation Wholesale Market Cost of Construction and Fuels 52!
Coal-Fired GenerationType of Generation+ Coal-fired plants provide baseload generation, by running approximately 90 percent of the time.Environmental Issues- Greater air emissions than natural gas-fired plants, including rate of about twice the CO2 per kWh generated.- Risk of higher costs due to future carbon-capture requirements.Cost of Construction and Fuels+ Currently, pulverized coal generation is economical to build based on current natural gas prices.+ Long-term domestic supply of coal, including lignite.+ Fuel cost is relatively low- High initial capital costs relative to natural gas-fired plants. 53!
Natural Gas-Fired GenerationType of Generation- Natural gas plants, such as combined-cycle plants, can provide baseload generation, but demand conditions in ERCOT result in a lower capacity factor than for coal-fired or nuclear-powered generation.+ Other simple-cycle natural gas plants have quick start-up and shut-down times to allow them to meet peak demand.Environmental Issues+ Lowest air emissions among fossil fuels.+ Newest power plants operate more efficiently, burning less fuel per MWh of generation.Cost of Construction and Fuels+ Low initial capital costs.- When natural gas prices are high, gas-fired power plants are expensive to operate. 54!
Nuclear-Powered GenerationType of Generation+ Nuclear-powered plants provide baseload generation by running approximately 90 percent of the time.Environmental Issues+ No air emissions.- Long-term storage of waste needs to be implemented.- Historic concerns regarding public perception of safety of nuclear power.Cost of Construction and Fuels+ Lowest fuel cost of all large-scale generation.- High capital costs.- Longest permitting and construction times among generation types. 55!
Wind-Powered GenerationType of Generation+ Wind is plentiful in certain parts of Texas.- Wind blows intermittently, making it a less reliable power source.Environmental Issues+ No air emissions.- Can affect migratory birds.- Concerns about aesthetic impact.Cost of Construction and Fuels+ No fuel cost.- Limited ability to replace other generation to satisfy reserve margins.- Imposes other costs on the system, such as increased ancillary service requirements, backup capacity and the need for transmission lines to reach rural wind farms. 56!
Solar GenerationType of Generation+ Solar power is generally reliable, but intermittent, as it depends on certain levels of sunlight.- Plants are generally small in scale.Environmental Issues+ No air emissions.- Large areas of land needed for effective solar arrays.Cost of Construction and Fuels- Can have 15 to 20 times the capacity cost of natural gas-fired generation+ No fuel cost.- Cannot be used to replace other generation to satisfy reserve margins.- Imposes other costs on the system, such as the need for transmission lines, since large-scale solar power plants would be located in areas far from population centers. 57!
Biomass and Landfill GasGenerationType of Generation+ Biomass and landfill gas generation generally operates reliably.- Plants are generally small in scale.Environmental Issues- Plants burning biomass can have high CO2 emissions.+ Landfill gas facilities reduce methane greenhouse gas emissions.- Generation is difficult to permit and site.Cost of Construction and Fuels- Requires high capital and operating costs when compared with fossil fuel-fired generation- Often located far from population centers, requiring high transmission costs 58!
Hydroelectric GenerationType of Generation+ Hydroelectric power is reliable to operate, except during drought.- Texas has very little potential for new hydroelectric power generation.Environmental Issues+ No air emissions.- Can kill fish.Cost of Construction and Fuels+ Once built, hydroelectric power is among the least expensive forms of power, as it has no fuel costs.- High capital costs 59!
Energy Efficiency andDemand-Side ManagementType of Technology+ Several cost effective solutions available.- Success requires broad implementation.Environmental Issues+ Reduces emissions that would otherwise accompany fossil fuel usage.Cost of Construction and Fuels+ Can improve cost levels for residents and customers.+ Reduces need for building new power supply. 60!

CO2 Emissions in Context of Texasʼ Economy!A common refrain is that CO2 emissions generated in Texas are higher than inother states. However, it is critical to view that in the context of other truths:− Texas generates more electricity than any other state; in fact, Texas produces almost 80% more electricity than the next most generating state.1− Much of the CO2 emitted in Texas results from the generation of “products” that are very significant to our state and nation. For example, Texas produces about: − 60% of petrochemicals produced in the U.S. − 30% of gasoline and diesel refined in the U.S. − 10% of electricity generated in the U.S.− The dollars of gross product produced in Texas per ton of CO2 emitted is high, and it increased by more than 1000% between 1963 and 2001.2− The amount of CO2 emitted per MWh of electricity generated in Texas is lower than that of half of the states that have more than a nominal amount of coal-fired or oil- fired electricity generation.31Source: EIA, 2008 State Electricity Profiles2Source: “Global Warming: What Should Texas Do?” Texas Public Policy Foundation, April 20073Source: EPA Acid Rain Database, 2009 67!

Additional Emission Reductions Cross State Air Pollution Rule (CSAPR) − EPA finalized the Cross State Air Pollution Rule on July 7th, 2011. The rule covers 27 states including Texas and requires significant reductions from power plants of Sulfur Dioxide (SO2) and Nitrogen Oxides (NOx). The CSAPR replaces the remanded Clean Air Interstate Rule (CAIR). − Based on the budget allocation, power plants in Texas as a whole will have to make about a 50% reduction from 2010 emissions, in SO2 emissions and an 11% reduction in NOx, by the end of 2012. Regional Haze − Requires reductions in NOx, SO2, and Particulate Matter (PM) emissions based on best available retrofit technology (BART) for different types of facilities, including electric generating units, industrial boilers, and refineries. − EPA has decided that NOx and SO2 emissions reductions made for CAIR will suffice for the NOx and SO2 emissions reduction requirements under Regional Haze. − The TCEQ is developing rules to implement BART. 71!

TDUsʼ Role in the Competitive ERCOTMarket!• Transmission and 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, natural 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 75!
TD Market Design:!ERCOT!• ERCOT Transmission – 1995 amendments to the Public Utilities Regulatory Act (PURA) required PUC to ensure open access to transmission grid, allowing new independent generators to utilize transmission network. – TX76RSB 7 adopted “postage stamp” transmission pricing structure and eliminated impact of location on transmission rates. – Transmission Cost of Service (TCOS) ratemaking structure implemented and billed to distribution service providers (DSP). – DSPs recover TCOS through the TDSP delivery rate and transmission cost recovery factor (TCRF), approved by PUC. – New transmission investment is coordinated through the ERCOT regional transmission planning process and requires PUC facility certification. 76!
Transmission Investment in Texas • Since 2009, TDUs have invested over $2.0 billion in the ERCOT transmission grid. • ERCOT estimates that the electric grid will require adding or improving 5,993 circuit miles of transmission lines at a cost of over $9.0 billion from 2011 through 2016 and beyond. • This investment includes the cost of integrating Competitive Renewable Energy Zones (CREZs) into the competitive ERCOTSource: ERCOT, “Report on Existing and Potential Electrical System market.Constraints and Needs,” December 2010 77!
Continued Transmission and DistributionInvestment Needed Throughout Texas• 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.• Texas must provide regulatory certainty and fair rates of return to ensure appropriate capital investment.• Though not shown here, areas of Texas located outside the ERCOT grid are also growing, both in terms of population and economic development. Source: ERCOT, “Report on Existing and Potential Electric System Constraints and Needs,” December 2010 78!
Challenges of TransmissionLine Construction Example of Transmission Construction Process in ERCOT• 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. 79!
Distribution InvestmentAlso Needed• The need to replace an aging distribution infrastructure to meet population and demand growth will require continued investment.• It is becoming more evident that rising construction material costs are an increasingly important driver contributing to the higher actual and planned utility industry infrastructure investments.• Nationwide, distribution investment is expected to be almost triple the size of projected transmission spending, according to the Edison Electric Institute. Distribution investment is likely to exceed generation and environmental capital spending, as well. 80!
TD Market Design:!Non-ERCOT!• Non-ERCOT Transmission – Wholesale open access transmission rights subject to Federal Energy Regulatory Commission (FERC) jurisdiction. – FERC transmission pricing reflects location of generation. – FERC requires generators to bear higher cost relative to the ERCOT system of connecting with the transmission grid. – Certification in Texas is with the PUC. – Recently adopted PUC rules allows most non-ERCOT utilities to recover transmission investments between rate cases through a transmission cost recovery factor (TCRF). 81!
Competitive Renewable Energy Zones:!Legislative and Regulatory Steps• The Texas Legislature mandated steady increases in renewable power in TX76RSB 7 (1999) and TX791RSB 20 (2005). – Starting Line: 880 MW in 1999 – Old Goal 1: 2,880 MW by 2009 (Achieved by 2007) – New Goal 1: 5,880 MW by 2015 – New Target 1: 10,000 MW by 2025 – New Target 2: 500 MW non-wind renewable generation• TX791SB 20 (2005) also required PUC to: – designate Competitive Renewable Energy Zones (CREZs) in areas in which renewable energy resources and suitable land areas are sufficient to develop generating capacity from renewable technologies; – develop a plan to construct necessary transmission capacity in a manner that is most beneficial and cost effective to customers; and – take into account transmission constraints, the need for generation and the level of financial commitment by generators when defining CREZs.• PUC adopted Substantive Rule 25.174 in December 2006, which creates framework for determining CREZs.• Texas currently has 9,727 MW of installed renewable generation capacity (September 2010). 82!
