Electric Market Structures in Texas
25
Pre-1975• Cities regulated electric utility service and rates.• Generally, a declining cost industry – rate applications most often filed to decrease rates.
1975• Inflation, construction costs and fuel costs drive electricity rates up.• 64th Texas Legislature enacts Public Utility Regulatory Act (PURA) to implement state regulation of
electric utility service and rates (Cities permitted to retain original jurisdiction).– Service area, transmission line and generating plant certification.– Rate regulation (based on cost of service plus reasonable return on investment).– Rates based on historical test year costs and original costs of infrastructure, less depreciation.– Service quality regulation.– Customer protection.
History of Electric Utility
Regulation in Texas
26
1976-1995
• 1978 U.S. Fuel Use Act required utilities to discontinue use of natural gas and encouraged the use ofcoal and nuclear for fuel.
• Inflation, volatile fuel costs and the need to add new generating capacity continue to increaseelectricity rates.
• Rate proceedings at PUC become increasingly adversarial.– Consumer groups concerned about frequency and amount of rate increases.– Utilities concerned about increasingly large PUC cost disallowances that are at odds with the
regulatory compact and erode rates of return.
• Large customers tire of subsidizing other ratepayers seek opportunities to by-pass regulated rates andobtain choice of suppliers.
– Cogeneration/self-generation.
– Advocate wholesale competition and transmission open access.
– Advocate “retail wheeling”.• Natural gas was favored again when the 1978 U.S. Fuel Use Act was repealed in the 1990s.

Wholesale and Retail Electric
Competition 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 theHouse 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 theHouse 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.
29
• 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-basedprices in ERCOT.
– Deregulated electric cooperative distribution rates.
Note: Non-ERCOT areas are subject to FERC jurisdiction for wholesaleservices, including transmission services.
Steps to Competition:
Wholesale Competition
30
• ERCOT market restructuring legislation, Senate Bill 7, passed in1999– 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 by50%, and sulfur dioxide emission from coal-fired facilities by 25%.
• Utilities required to fund energy efficiency programs equal to at least 10% of eachyear’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.

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
32
• Incumbents required to separate business activities into the followingunits.– 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.
Structural Unbundling
33
ERCOT: Separate companies provide
retail, transmission & distribution and
generation services
• 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 thePUC sets transmission and distribution rates.

34
ERCOT: Separate companies provide
retail, transmission & distribution and
generation services
• Because wholesale electric prices are set by the competitive market, therisks associated with the cost of construction, operations and maintenanceof a generation plant are borne entirely by the generator and its investors,not by end-use customers.

and generation services in each area
• In fully regulated markets, the PUC sets retail rates charged to end-usecustomers.
• Each of these service areas is part of multi-state electric grids, withdiffering regulations. In many cases, vertically integrated utilities purchasewholesale power from certain unregulated entities.

Texas’ Wholesale
Electric Markets
38
The Competitive Wholesale Market: A
Success Story
Competition has brought greater efficiencyto 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 onmaintaining 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.

Market Management
• System Reliability– ERCOT oversees system reliability.– ERCOT is part of national reliability council.– ERCOT protocols, approved by PUC, mandate system reliability standards that all
market participants must follow.
• Statute and Rules Address “Market Power” and Generation Merger Issues– Independent Market Monitor oversees wholesale market operations.– Generating capacity owned and controlled by a Power Generation Company limited to
20% of installed generating capacity capable of delivering power to a power region.– Administrative penalties for market power abuse were reviewed and updated during the
79th Regular Session.– Mergers of Power Generation Companies subject to PUC review.
• Market Design– ERCOT will transition to a Nodal Market in 2009 as a result of PUC rulemaking.– The change is expected to bring cost-savings and additional efficiency to the market by
enhancing market transparency and allocating costs more accurately to marketparticipants.

ERCOT Generation Mix
48
ERCOT Generation Mix
• The generation technology mix is an outcome of a robust competitive wholesalemarket and environmental policy decisions.
• In addition to the price of fuels and the cost of technology, environmental and sitingissues impact choices made by generation developers.
• Coal, including lignite, is an important fuel in the ERCOT electric generation mix.
– Coal is the most abundant fossil fuel in the United States, with an estimated200 year supply remaining (per the Energy Information Administration (EIA)).
– Electricity produced from Texas lignite exceeds the entire generation of 28states individually.
• Texas lignite accounts for about 45% of the coal used in the state for electricity.• Texas’ lignite mining industry is a key part of the state economy, providing over
33,000 permanent jobs and contributing about $10.5 billion in annual TotalExpenditures.
• The existing framework of Texas’ competitive wholesale electric market has helpedlead generators to invest in and announce plans for over 27,000 MW of newgeneration, including natural gas, coal, nuclear and renewable power.

Gas on the Margin in ERCOTYear-Round
Examples are purely illustrative
• There are multiple types of power plants with different operations in ERCOT that are operatedon different schedules.
– Because of their lower marginal costs, nuclear and coal-fired power plants in ERCOT operateapproximately 90 percent of the time.
– In contrast, natural gas-fired power plants are ramped on and off, depending upon demand.– Wind-generated electricity is only intermittently available, depending on wind conditions.
• Some natural gas-fired generation is required to operate at all times in the ERCOT region tomeet demand.
– Natural gas-fired generation sets the market price of wholesale electricity in ERCOT.– Natural gas-fired units that are used to meet peak demand tend to be older units that cost more to
operate.
52
Business Climate for Generatorsin ERCOT
• In ERCOT, generation companies assume all of the financial risk included in a new generationprojects.
• The decision to build new generation thus depends upon whether the generator believes theelectricity can be sold at a price to recoup construction costs, cover operations andmaintenance costs and achieve a profit.
• Market forces have been effective in bringing new generation to the state, with over 37,063MW of generation constructed since the advent of wholesale competition in 1995. Another4,433 MW of new generation is under construction, according to the PUC.
• While not all is expected to the built, the PUC reports 25,756 MW of new generation has beenannounced:
– 6,389 MW of new coal-fired generation– 6,002 MW of new nuclear generation– 8,012 MW of new wind-powered generation– 5,253 MW of new natural gas-fired generation
• Though such news is positive, market forces and legislative and regulatory certainty willultimately dictate how much of the announced new generation is actually built.

Cost of Construction and Fuels
Type
of G
ener
atio
n
55
Coal-Fired Generation
Type 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.
56
Natural Gas-Fired Generation
Type of Generation- Natural gas plants, such as combined-cycle plants, can
provide baseload generation, but demand conditions inERCOT result in a lower capacity factor than for coal-firedor nuclear-powered generation.
+ Other simple-cycle natural gas plants have quick start-upand 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.
57
Nuclear-Powered Generation
Type 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.
58
Wind-Powered Generation
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 ruralwind farms.
Type 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.
59
Solar Generation
Type 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 populationcenters.
60
Biomass and Landfill GasGeneration
Type 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
61
Hydroelectric Generation
Type 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
62
Energy Efficiency andDemand-Side Management
Type 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.

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 almost80% more electricity than the next most generating state.1
− Much of the CO2 emitted in Texas results from the generation of “products” that arevery 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 itincreased by more than 1000% between 1963 and 2001.
− The ratio of the amount of CO2 emitted per MWh of electricity generated in Texas islower than half of the states that have more than a nominal amount of coal-fired or oil-fired electricity generation (see previous slide).

Federal Clean Air Interstate Rules (CAIR)− Requires additional NOx and SO2 emissions reductions from power plants in
2009, 2010, and again in 2015, with a cap and trade program.− The NOx and SO2 emissions from all new units must “fit” under the 2009, 2010,
and 2015 caps; such emissions are not in addition to those caps.− TCEQ has recently revised its rules to implement CAIR.
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 willsuffice for the NOx and SO2 emissions reduction requirements under RegionalHaze.
− The TCEQ is developing rules to implement BART.

mercury emissions from power plants− Would have required a 70% reduction of mercury emissions from
power plants in all 50 states− If EPA has to set a Maximum Achievable Control Technology
(MACT) standard:− the new emissions standard for each existing and new facility needs to
be set according to fuel type− Different coals will require different controls and considerations.

Transmission and Distribution Utilities
77
• 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 nuclearfacilities
TDUs’ Role in the Competitive ERCOT
Market
78
• ERCOT Transmission– 1995 amendments to the Public Utilities Regulatory Act (PURA) required PUC to
ensure open access to transmission grid, allowing new independent generators toutilize transmission network.
– TX76RSB 7 adopted “postage stamp” transmission pricing structure and eliminatedimpact of location on transmission rates.
– Transmission Cost of Service (TCOS) ratemaking structure implemented and billedto 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 regionaltransmission planning process and requires PUC facility certification.

Transmission Investment in Texas
• Since 2006, TDUs haveinvested about $2.5 billionin the ERCOT transmissiongrid.
• ERCOT estimates that theelectric grid will requireadding or improving 2,888circuit miles of transmissionlines at a cost of about $3billion from 2009 through2013.
• In addition, the integrationof Competitive RenewableEnergy Zones (CREZs) intothe competitive ERCOTmarket will requireadditional investment ofabout $4.9 billion.

Continued Transmission and DistributionInvestment Needed Throughout Texas
• According to the Texas State DataCenter, 5 million new residents areexpected in Texas by 2020.
• New generation must be deliveredeffectively and efficiently topopulation centers of the state.
• Texas must provide regulatorycertainty and fair rates of return toensure appropriate capitalinvestment.
• Though not shown here, areas ofTexas located outside the ERCOTgrid are also growing, both in termsof population and economicdevelopment.

81
• While certain types of generation can be constructed quickly -- often as short as 12-18months -- transmission lines typically take between three and five years. Generation can bebrought into the market more rapidly if the siting takes advantage of the existing transmissioninfrastructure.
• Building long transmission lines can affect many landowners, often requiring a lengthy andextensive easement acquisition effort.
• The transmission line siting process must take into account the impact of those lines onenvironmentally sensitive and historically significant lands.
• Utility is not typically allowed to begin recovering costs until year 5 or 6.
Challenges of TransmissionLine Construction
Example of Transmission Construction Process in ERCOT
82
Distribution InvestmentAlso Needed
• The need to replace an aging distributioninfrastructure to meet population and demandgrowth will require continued investment.
• It is becoming more evident that rising constructionmaterial costs are an increasingly important drivercontributing to the higher actual and planned utilityindustry infrastructure investments.
• Nationwide, distribution investment is expected to be almost triple the size ofprojected transmission spending, according to the Edison Electric Institute.Distribution investment is likely to exceed generation and environmental capitalspending, as well.
83
• 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 ERCOTsystem of connecting with the transmission grid.
– Certification in Texas is with the PUC.
– Recently adopted PUC rules allows most non-ERCOT utilities to recovertransmission investments between rate cases through a transmission costrecovery factor (TCRF).

Competitive Renewable Energy Zones:
Legislative and Regulatory Steps
• The Texas Legislature mandated steady increases in renewable power inTX76RSB 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 capacityfrom renewable technologies;
– develop a plan to construct necessary transmission capacity in a manner that is mostbeneficial and cost effective to customers; and
– take into account transmission constraints, the need for generation and the level offinancial commitment by generators when defining CREZs.
• PUC adopted Substantive Rule 25.174 in December 2006, which createsframework for determining CREZs.
• Texas currently has 8,976 MW of installed renewable generation capacity (Oct2009).

Energy Efficiency in Texas:
Overview
• Texas continues to be an energy leader through policies designed to improve the state’s
energy efficiency programs and bring improved technologies to the electric market.
– Utility programs have reduced customer consumption that has allowed existing resources to meet
new customer load, reducing the need for new generation.
– Advanced metering can help customers better manage their electric usage by providing information
and opportunities that enable customer to take control of their energy consumption and bills.
• The Texas Electric Choice Act requires electric utilities to provide energy efficiency
programs and incentives, including low-income energy efficiency programs.
– TX80RHB 3693 raised the energy efficiency goal for electric utilities from 10% of annual demand
growth to 15% in 2008 and 20% in 2009.
• ERCOT competitive retailers are developing innovative plans and products that will help
customers use less energy (e.g., customer education programs, energy audits, Internet-
controllable thermostats, etc.)
90
Energy Efficiency Programs
Have Exceeded Goals
• In 2008, utilities in Texas exceeded their statewide legislative energy efficiency goals for thesixth straight year. Utilities achieved 202 MW of peak demand reduction in 2008, which was76% above their 115 MW goal.
• Energy savings from standard offer programs and market transformation programs resultedin an equivalent reduction of 882,519 pounds of nitrogen oxide emissions per year.

TX80RHB 3693:
Enhancing Energy Efficiency
TX80RHB 3693 included a host of programs designedto help reduce electricity usage in Texas.
• Raises energy efficiency goal for electric utilities from 10% of annual demand growth to 15%
in 2008 and 20% in 2009.
• PUC will study energy efficiency programs by January 15, 2009, and submit a report to the
legislature.
– The study shall address whether utility energy efficiency programs should continue and whether
energy efficiency programs are best provided by the competitive market.
– The findings of the study will determine whether a goal increase to 30 percent is achievable by 2010
and 50 percent by 2015.
• PUC will work with ERCOT to develop a method to account for projected energy efficiency
impacts in ERCOT’s forecasts of future capacity, demand, and reserves.
92
TX80RHB 3693:
Enhancing Energy Efficiency
• The bill also includes:
– an energy efficiency cost recovery factor;
– a utility financial incentive for exceeding goals; and
– the ability for utilities under a rate freeze to defer recognition of these costs.
– Provisions aimed at reducing energy consumption by schools and government
buildings.
– Stronger, more energy-efficient building standards for low-income housing.
– Creates an annual sales tax holiday during Memorial Day weekend for energy efficient
products that bear the designation of the nationwide “Energy Star” program.

Advanced Metering Activities
in Texas
• CenterPoint Energy and Oncor have received approvals from the Public Utility Commissionof Texas (PUC) to deploy advanced metering systems (AMS) across their respectiveservice territories.
• The approved deployment plan for CenterPoint Energy calls for installation of advancedmeters over five years beginning in March 2009. Through mid-September, CenterPointEnergy has installed over 76,500 advanced meters and expects to install a total of 145,000meters by year-end.
• Oncor’s approved deployment plan initiated in late 2008 will have installation of advancedmeters completed by the end of 2012. To date, Oncor has installed 294,000 meters.
• The cost for the meters will be recovered through a monthly surcharge, which may beadjusted over time to reflect both the inclusion of AMS costs in future base rates andvariances between the estimated versus the actual cost of implementing the deploymentplan. The respective surcharges for both Oncor and CenterPoint Energy take into accountthe savings advanced meters are expected to bring each company.
• AEP Texas has filed its deployment plan with the PUC and anticipates approval by thefourth quarter of this year.

97
The ERCOT Competitive Retail Electric
Market is Providing Strong Customer
Benefits
Key Takeaways– Since the start of retail competition, more than four out of five eligible ERCOT customers
have chosen a new REP or a new product with their existing REP.– Costs and prices have risen in competitive areas, in areas served by municipally owned
utilities and in areas served by electric co-ops.– Natural gas influences wholesale electric prices in Texas, and, due to natural gas
increases over the past several years, wholesale electricity prices have increased -- butonly about half as much as natural gas prices.
– Retail electric prices have grown far less than other energy commodities, such asgasoline, crude oil, natural gas and coal.
– Available prices in the ERCOT competitive electric market are falling significantly, a starkcontrast to the national average which is rising and projected to keep rising. In fact, theaverage U.S. residential power price is expected to increase 9.4 percent in 2009,according to the federal government.
– Natural gas prices reached an all-time high in July, but they’ve subsequently fallen overthe past few months. Because of the robust competition among multiple viable retailelectric providers (REPs), residential electric price offers have fallen by over 28 percent.
– The System Benefit Fund (SBF) provided benefits for low-income Texans during thesummer. Several retailers, including AECT member companies, also offer additional low-income customer assistance programs, so customers should also contact their REP tolearn more about the options that might be available to them.

Benefits for Qualified
Low-Income Customers:
The System Benefit Fund
• The System Benefit Fund (SBF) was enacted as part of the TexasElectric Choice Act in 1999. It is intended to provide funding specificallyfor:– assistance to low-income customers through reduced electric rates;– weatherization programs; and– administrative funding.
• The PUC approved the utilization of the $80 million of SBF fundsauthorized by the 80th legislature.– These funds will be used to provide a discount to low-income customers in
the competitive areas of the state.– During the months of May through September, eligible low-income customers
will receive an approximate 20 percent discount through the “LITE-UP Texas”electric discount program.
109
Benefits for Qualified
Customers: REP Programs
• Several retail electric providers across the state also provide additional, voluntaryprograms to assist low-income customers. Examples of programs include:
– Since May 2003, the Neighbor-to-Neighbor program has helped tens-of-thousands of Direct Energy,CPL Retail Energy, and WTU Retail Energy customers with their home energy expenses. The programwas created to assist families experiencing financial emergencies with up to $200 in bill paymentassistance, as much as twice during a calendar year. The program is administered by more than 30community action agencies across the state.
– The Care to Share Fund provides bill payment assistance to eligible First Choice Power residentialcustomers in need of emergency funding. Customers can donate to the Care to Share Fund and assistresidential customers who need a little extra help by providing extra emergency assistance through theCare to Share Fund.
– The CARE Energy Assistance Program was created by Reliant Energy to help Reliant customersduring a difficult time. Customers who qualify may receive this one-time annual assistance through non-profit social service agencies in communities that are served by Reliant Energy. These agencies reviewcustomer cases and qualify them based upon the agency’s designated hardship criteria.
