AECT Principles! • AECT is an advocacy group composed of member companies committed to: - Ensuring a modern, reliable infrastructure for the supply & delivery of electricity. - Supporting efficient competitive markets that are fair to customers and market participants. - Supporting consistent and predictable oversight and regulation that will promote investment and ensure the stability of Texas’ electric industry. - Promoting an economically strong and environmentally healthy future for Texas, including conservation and efficient use of available resources. • AECT member companies remain dedicated to providing Texas customers with reliable service and are committed to the highest standards of integrity. The Association of Electric Companies of Texas, Inc. (AECT) is a trade organization of investor- owned electric companies in Texas. Organized in 1978, AECT provides a forum for member company representatives to exchange information about public policy, and to communicate with government officials and the public.

U.S. Divided into Eight!Reliability Regions! • The eight reliability regions in the FERC continental U.S. are subject to the oversight and enforcement authority of NERC the North American Electric Reliability Corporation (NERC), which is subject to the Federal Energy Regulatory Commission’s (FERC) oversight. NERC is responsible for developing standards to ensure and improve reliability for delivery of electricity on the bulk power system.• Electric systems in Texas are located within four separate reliability regions: - Texas Reliability Entity (TRE), which oversees participants in the Electric Reliability Council of Texas (ERCOT); - SERC Reliability Corporation; - Southwest Power Pool (SPP); and - Western Electricity Coordinating Council (WECC). (ERCOT) 3

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. 6
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. 7
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. 8
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. 9
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. 10!

Renewable Development:!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 12!
Renewable Development:!Legislative and Regulatory Steps• 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 10,135 MW of installed renewable generation capacity (March 2011). 13!

Federal Production Tax Credit!Set to Expire!• The federal production tax credit (PT) began with the Energy Policy Act in 1992. – PTC is a 10-year inflation-adjusted tax credit that started at 1.5¢/ kWh – Credit based on amount of electricity produced.• Wind PTC set to expire on December 31, 2012• Legislation has been filed to extend the tax credit. 18!
