Tennessee Valley Authority

Compensation Plan

Principles

Authority

The Tennessee Valley Authority (“TVA”) Compensation Plan provides the framework for Management, the People and Performance Committee, and the Board of Directors of the Tennessee Valley Authority (“TVA Board”) to establish and manage compensation for all TVA employees in a manner that is in compliance with the TVA Act as amended by the Consolidated Appropriations Act, 2005. The TVA Board approves the Compensation Plan and ensures that it is consistent with the TVA Act and TVA’s Strategic Plan.

The TVA Act, as amended, provides that the Board will approve and establish a compensation plan for TVA employees which:

• Specifies all compensation (including salary or any other pay, bonuses, benefits, incentives, and any other form of remuneration) for the Chief Executive Officer (“CEO”) and TVA employees.

• Shall be based on an annual survey of the prevailing compensation for similar positions in private industry, including engineering and electric utility companies, publicly owned electric utilities, and Federal, State, and local governments.

• Shall provide that education, experience, level of responsibility, geographic differences, and retention and recruitment needs will be taken into account in determining compensation of employees.

The TVA Act also provides that:

• The Board shall approve all compensation (including salary or any other pay, bonuses, benefits, incentives, and any other form of remuneration) of all managers and technical personnel that report directly to the CEO (including any adjustment to compensation).

• On the recommendation of the CEO, the Board shall approve the salaries of employees whose annual salaries would be in excess of the annual rate payable for positions at Level IV of the Executive schedule.

• The CEO shall determine the salary and benefits of employees whose annual salary is not greater than the annual rate payable for positions at Level IV of the Executive schedule.

The Compensation Plan is continuously reviewed to ensure consistency and alignment with TVA’s mission and Strategic Plan. The Compensation Plan includes the following key elements:

1

Philosophy

TVA’s Compensation Philosophy is based on certain statutory requirements and is designed to attract, engage, and retain the employees needed to accomplish the agency's broad mission. Under the TVA Act, TVA has its own personnel system; however, employees are public servants.

In their service, many employees are called on to accomplish specialized aspects of the mission safely, reliably and efficiently, and must have the requisite education, experience and professional qualifications. These requirements make it necessary for TVA to offer compensation opportunities to its specialized employees that motivate them to stay with TVA in order to provide TVA with the necessary resources to attract highly qualified candidates for positions similar to those in relevant industries.

Performance-based compensation is critical to TVA in achieving its strategic goals. A key component of the Compensation Philosophy is a strong orientation toward "pay for performance" which rewards continuous improvement in TVA’s overall performance as well as that of individual business units and individual participants.

TVA’s Compensation Philosophy is a structured, market, and performance based approach to use when determining pay levels and incentive opportunities. For those positions requiring specialization, compensation is designed to be comparable to the sector from which TVA would recruit and those likely to recruit TVA employees.

• Compensation is targeted at the median (50th percentile) of the labor market for most positions

• Compensation may be targeted above median of the relevant labor market (typically between 50th and 75th percentiles) for certain positions due to market scarcity, recruitment and retention issues, and other business reasons (e.g., Nuclear and Transmission positions)

Competitive compensation levels are determined using relevant labor market data obtained through surveys and proxy reviews and validated through recruitment and periodic supplemental benchmark activities.

Additionally, compensation for TVA trades and labor employees is based on prevailing pay for similar work. Section 3 of the TVA Act requires the prevailing rate of wages for work of a similar nature prevailing in the vicinity be paid to laborers and mechanics whether employed by contractors or directly by TVA. Compensation for other represented employees is based on total compensation levels, market rates, practices, and methods of payment for similar work in the relevant labor market consistent with applicable labor agreements.

TVA’s Employee Benefits program offers a competitive benefits package to attract and retain the workforce required for TVA to achieve its mission successfully while prudently managing costs, ensuring optimum use of benefit dollars, engaging employees and retirees to become informed consumers and partnering in managing benefit costs.

TVA maintains a qualified retirement plan for all employees, which is competitive with the relevant labor market.

Strategy

Compensation Basis

Executives, Management & Specialist, and Excluded Employees

In accordance with the TVA Act, as amended, the level of compensation for Executives, Management and Specialists will be based on annual market survey data that represent prevailing competitive compensation for similar positions in private industry, including engineering and electric utility companies, publicly owned electric utilities, Federal, State and local governments.

Non-management and specialist employees who are not covered by one of our bargaining units due to the sensitive and confidential nature of their work are categorized as Excluded Employees. Compensation for employees in this category will be based on annual market survey data that represent prevailing competitive compensation for similar positions in the relevant labor market. Compensation for Excluded Employees will be targeted, in general, at the median of the relevant labor market for all positions.

Represented Employees

Trades and Labor Represented Employees

TVA annually conducts a wage survey within a specified geographic vicinity and negotiates with the Trades and Labor Project Agreement Council representing contractor employees from multiple building trades unions to establish an agreed upon prevailing wage rate. Any dispute over what the rate should be may be appealed to the Secretary of Labor under the TVA Act for a final decision. TVA contractors are required to pay these prevailing rates, and unions provide craftspersons to the contractor's job at these rates. The same total wage package applies to all work sites.

TVA also annually conducts a prevailing wage survey for work performed by TVA Trades and Labor employees directly. The prevailing wage rate is negotiated between TVA and the Annual Council representing multiple unions and the Teamsters for jobs each represents. Disputes over the prevailing rate may be appealed to the Secretary of Labor.

Salary Policy Represented Employees

As required by Labor Agreements, surveys, published data, and/or other sources are reviewed annually by TVA and the applicable unions to negotiate compensation budgets and pay adjustments. Disputes over monetary issues are resolved through binding arbitration.

Candidate Sourcing and Relevant Labor Markets

External recruiting areas are defined for specialized segments of TVA’s employees based on the most likely sources of qualified candidates and the sectors in which TVA is most vulnerable to external recruitment activities.

External recruitment sources for the most senior levels of Management (CEO, direct reports to the CEO and other select executives) have been determined to be primarily energy services companies (including investor owned utilities of comparable size and business complexity and large public power organizations) due to the criticality of industry-specific knowledge, experience, and professional qualifications in carrying out the duties of these positions.

However, some senior level positions which have less need for industry-specific knowledge and experience may have recruitment areas in general industry and governmental entities in addition to the energy services industry and public power.

External recruitment areas for other segments of TVA employees may include general industry, governmental entities, energy services companies and investor owned utilities.

Relevant labor markets for other segments of TVA employees are continuously reviewed and will reflect consideration of potential recruiting sources, external recruiting threats, geographic scope of recruitment activities, type of business/industry, type of position, etc.

Sources of Competitive Market Compensation Information

Competitive market compensation information is obtained from:

• Published and custom compensation surveys reflecting the relevant labor markets identified for designated positions

• Publicly disclosed information from a custom peer group of energy services companies of comparable size and business complexity as reviewed and approved by the Committee from time to time

The competitive market compensation information is used to:

• Test competitiveness of compensation level and opportunity by position

• Serve as a point of reference for establishing pay packages for recruiting executives

• Determine appropriate adjustments to compensation levels and opportunities to maintain the desired degree of market competitiveness

The development of competitive market references that reflect the primary sources of candidates does not limit the potential candidates to those sources. For example, the fact that the market reference for a position reflects median compensation for energy services companies simply informs as to the likely pay levels necessary to attract and retain talent for that position and should not limit TVA’s recruiting efforts to energy services companies.

Pay for Performance

A key feature of the Compensation Plan is a strong orientation toward pay for performance for all employees. The at-risk, pay for performance elements play a substantial role in executive pay and are guided by TVA's business strategy to ensure appropriate alignment between strategy and motivation/reward. The Plan also seeks to strike the appropriate balance between achieving short-term annual results and ensuring TVA’s long-term success and viability.

The Company’s incentive plans are linked to financial and operational goals (as defined in TVA's Strategic Plan) emphasizing improvements in TVA's overall performance as well as that of individual business units. The range of incentive opportunity for TVA executives is explicitly calibrated to the degree of difficulty in achievement of specific goals as defined in the business plan.

TVA continuously reviews the goals and measures that are used in its pay for performance plans to ensure they support the achievement of TVA's Strategic Plan. Through pay for performance, the Compensation Plan recognizes individual performance and focuses attention on the achievement of business goals that are important to customers, and the people it serves.

The Company’s annual incentive plan achieves this objective through the use of a Balanced Scorecard, while the Company’s long-term incentive program emphasizes a performance orientation by targeting a concentration of approximately 80 percent of long-term compensation in the form of at-risk, performance-based compensation.
