A Focus on Organizational Effectiveness

The TVA Office of the Inspector General (OIG) meets our legal requirement to report to Congress on our results twice a year through our Semiannual Report to Congress (SAR). This SAR edition focuses on the behaviors of the more than 10,000 TVA employees as equal in importance to TVA's operational processes and structure in TVA's capacity to achieve its mission of providing reliable power at affordable rates, environmental stewardship and economic development to the 9 million people of the Tennessee Valley. Additionally, we highlight our audit, evaluation, and investigative work that identified nearly $15 million in funds TVA could put to better use, questioned costs, recoveries and savings as well as opportunities for TVA to improve its programs and operations.

Navigating Risk – A Focus on Contracting

The OIG's latest Semiannual Report to Congress focuses on navigating risk, specifically in contracting. In our feature article, we discuss how our contract audit work helps TVA recover millions of dollars every year from contractors, negotiate better pricing for future contracts and improve contract administration. These results impact TVA's ability to manage its costs and maintain its financial health. We would be remiss if we also did not acknowledge that the strong working relationships Contract Audits and TVA contracting groups have built together over the years are integral to our success in this area.

Whether the focus of our work is contracting, cyber security, governance, operational or cultural risks, our intent is to provide TVA management with an independent and objective assessment of how well the risks are being mitigated and recommend solutions to issues that will help TVA become better.

Making TVA Better

On October 18, 2015, the Tennessee Valley Authority (TVA) Office of the Inspector General (OIG) celebrated its 30th anniversary. In those 30 years, the OIG, like TVA, has evolved. Our office was created as a Board-established office with a Board-appointed Inspector General (IG) during a time when TVA faced a crisis in the building of its nuclear plants. TVA, at the time, had a three-member fulltime Board of Directors (Board), received federal appropriations, and employed more than 50,000 people.

Building a Better TVA ... Together

I am pleased to present our report to Congress for the period October 1, 2014, to March 31, 2015. As discussed in our feature article, "Building a Better TVA ... Together," Tennessee Valley Authority (TVA) continues to face challenges from an operational and financial perspective. In these challenging times, it is especially evident that to best serve the people of the Tennessee Valley, the Office of the Inspector General (OIG) not only needs to provide an independent view of the issues facing TVA, but also work collaboratively with TVA management to identify optimal alternatives and the best solutions. Some may say balancing independence and collaboration is difficult. Our experience says it is not only possible, it is integral to helping TVA management and the TVA Board identify the best solutions to mitigate the risks and address the challenges that lie ahead.

Generating Power Through People

I am pleased to present our report to Congress for the period April 1, 2014, to September 30, 2014. As always, the Office of the Inspector General (OIG) directs its resources to conduct audits and investigations based on the ranking of risks to the Tennessee Valley Authority (TVA). Whether it is cyber security issues, contracts with vendors that pose loss of funds, or TVA employees or contractors engaging in illegal activities, the OIG works with TVA management to reduce the harm to TVA. In our feature article for this semiannual report, we discuss the importance of a healthy organizational culture at TVA and how culture poses a potential risk. We discuss TVA's efforts to assess its culture over the years and the attempts to sustain a more engaged workforce. In this feature article, we also announce the beginning of OIG reviews in January 2015 to assess organizational effectiveness at TVA. These reviews are designed to help TVA management assess how well they are doing both in meeting operational goals and in building a healthy culture. Given the significant challenges TVA faces, knowing how the level of employee engagement is affecting getting the desired results is imperative.

Balancing Mobility With Security

I am pleased to present our report for the period October 1, 2013, to March 31, 2014. Mobile technology advancements have changed the way we work. Because of these advancements, conducting business is no longer constrained to a physical location or a hard-wired computer. Today, collaboration and information sharing occur seamlessly anywhere, anytime from your smartphone or tablet. While this technology can increase operational effectiveness, there are risks. In this semiannual feature, we focus on the Office of Inspector General's (OIG) role in helping the Tennessee Valley Authority (TVA) balance the benefits and risks of incorporating mobile devices into the business.

Making TVA Better

I am pleased to present our report for the period April 1 to September 30, 2013. The fact that the Tennessee Valley Authority (TVA) is facing an environment of declining revenue and rising costs has been widely reported. TVA management and the TVA Board of Directors (Board) are making hard choices that involve cutting costs and at the same time becoming more efficient. Historically, the work of the Office of the Inspector General (OIG) has supported cost cutting and efficiency goals through our audits, evaluations, and investigations. In our feature for this semiannual report, entitled "Making TVA Better," we discuss how our work contributes to helping TVA save or recover money, reduce risks, and improve operations. We share a mutual purpose with the TVA Board and TVA management in making TVA better.

Navigating Risk – Challenges in Maintaining Financial Health

I am pleased to present our report for the period October 1, 2012, to March 31, 2013. As we have said previously, risk is at the heart of everything we do. In the feature for this semiannual report, we continue our focus on navigating risk by discussing the Tennessee Valley Authority's (TVA) challenges in maintaining financial health. In these difficult economic times, it is more important than ever for the Office of the Inspector General (OIG) to illuminate the risks we see and work with TVA management to find solutions to mitigate those risks so that prudent decisions can be made on the best use of TVA resources.

Navigating Risk – a Focus on Cyber Security

I am pleased to present our report for the period April 1, 2012, through September 30, 2012. Once again our theme focuses on navigating risks faced by the Tennessee Valley Authority (TVA) – specifically, cyber security risk. Business leaders and government officials alike recognize the significant risk posed from cyber security threats that are constantly changing. As discussed in the feature article in this semiannual report, given what is at stake, it is imperative that agencies are agile enough to handle not only their identified historical threats, but any future threats as well.

The Challenge of Managing Change

I am pleased to present our report for the period October 1, 2011, through March 31, 2012. The theme of our semiannual is "Managing Change," and our feature highlights the challenges with managing one particular change – the decision to increase the Tennessee Valley Authority's (TVA) reliance on nuclear energy.

Navigating Risk

In this semiannual period, our audit, inspection, and investigation activities resulted in almost $16 million in recoveries, fines/penalties, waste, potential savings, questioned costs, or funds which could be put to better use, as well as numerous recommendations to help TVA become better and recognize areas where additional controls may be necessary to adequately control risks.

Making TVA Better

The theme of this semiannual is "Making TVA Better." As you will see throughout this report, the TVA OIG employees are working hard to do just that. In this semiannual period, our audit, inspection, and investigation activities resulted in almost $35 million in recoveries, fines/penalties, potential savings, questioned costs, and funds which could be put to better use, as well as numerous recommendations to help TVA become better.

Creating an Environment of Change

We continue to monitor the progress TVA is making with both the Kingston coal ash clean-up efforts and TVA's overall record of environmental performance. Our report entitled "TVA's Environmental Performance Results" shows that TVA benchmarked against other utilities ranks in the middle on most environmental measures. This is the fourth in a series of benchmarking reports answering the question, "How is TVA doing." In addition, our Investigations organization remains engaged in investigating significant allegations of criminal and administrative misconduct related to TVA personnel or programs. TVA continues to do the hard work of rebuilding its reputation after the Kingston coal ash spill. In the feature article entitled "Creating an Environment of Change," we highlight TVA's road to redemption. Thus, our cover page is symbolic of TVA envisioning a brighter future on its journey to "2020."

Culture – Asset or Liability?

The Tennessee Valley Authority continues to live under the cloud of the Kingston ash spill of December 2008. The Office of the Inspector General is reminded of this shadow every day through our continuing review of TVA's efforts to return the Kingston area to its former state. We see TVA making steady progress on the physical cleanup; but more importantly, we see signs of an improvement in the TVA culture that contributed to this unfortunate environmental event.

Rebulding the Foundation

Change is coming to TVA and much of it is internally driven. Undoubtedly, the coal ash spill at the Kingston plant on December 22, 2008, set some of those changes in motion, but the TVA Board and TVA management have reacted with a commitment to make the changes necessary to make TVA better. Yes, Kingston was an environmental tragedy, but ultimately the TVA that is emerging is likely to be better able to serve the needs of Valley residents. As we have pointed out in our reports on Kingston, this was a disaster that did not need to occur. That is, however, true of most failures whether personal or, as in the case of TVA, institutional. And as with most failures, there are new opportunities for growth and TVA is seizing those opportunities.

Challenging Times

This report to Congress and the TVA Board comes at a time of historic challenges for TVA. We chronicle some of those recent challenges in the "Special Feature" on page 16 of our report. In many ways, a "perfect storm" has developed that has changed the landscape of TVA forever. As we note, a federal district court in Asheville, North Carolina, has ruled that a number of TVA 's fossil fuel plants have created a "public nuisance" that must be abated in short order. This has significant implications for the composition of TVA 's energy fleet and requires rethinking how TVA will meet the demand for power across the Valley.

Securing I.T.

The United States is facing an energy crisis of historic proportions and when coupled with the recent national economic instability, these two factors present utility companies like TVA with unique challenges. The electric utility industry is a very capital intensive industry requiring TVA to make large scale capital investment decisions. Risk is inherent in the process. How TVA manages those risks is particularly important today. We examined TVA's enterprise risk management program in this semiannual reporting period as part of our continued vigil as to how TVA is coping with challenging conditions.

Twenty Years of an Independent Light

In 1988, Congress established by law the Office of Inspector General at TVA. A fair question is, to what end? If we were judged on the same basis as private sector business units, how would we stack up? Did we pay our way? And perhaps the most important consideration, have we helped make TVA better?

...Resurgence of Nuclear Power...

This reporting period was marked by TVA leading the nation in the resurgence of nuclear power. TVA's commitment to nuclear power was demonstrated by (1) the restart of the Browns Ferry Nuclear Plant (BFN) Unit 1 in North Alabama in May; (2) Board approval in August for completion of a second nuclear reactor at the Watts Bar Nuclear Plant (WBN) in East Tennessee; and (3) Board authorization in September to submit an application to the Nuclear Regulatory Commission (NRC) for a combined construction and operating license for two new nuclear units at TVA's Bellefonte site in Hollywood, Alabama. The anticipated flurry of applications by private sector utilities with the NRC to build new nuclear plants is indicative of the belief within the utility industry that nuclear power is America's best option to meet growing power demands. TVA's successful restart of BFN Unit 1 on time and within budget has sparked renewed optimism that nuclear power is a viable, clean, and efficient source of energy. President George W. Bush recognized the significance of TVA's role in this area by his attendance at a special ceremony at BFN on June 21, 2007.

...Newly Constituted TVA Board...

This report to the TVA Board and to Congress concludes a full year for the newly constituted TVA Board which was sworn in on March 31, 2006. Legislation signed by President Bush in 2004 expanded the Board from three full-time members to nine part-time members with a full-time chief executive officer to run TVA on a day-today basis. As Director Skila Harris recently noted in an address to the TVA OIG, this change amounted to a "reinvention" of the TVA Board. Director Harris noted the differences in her role as one of the previous full-time Board members to her current service with her fellow part-time Board members. She also aptly noted that while most of the new Board members were familiar with independent auditors in private sector corporations, they had not worked before with Inspectors General.

...Diverse and Complex Organization...

I am pleased to present to you our semiannual report for the six-month period beginning April 1, 2006, and ending September 30, 2006. The efforts of the men and women of the TVA OIG resulted in almost $14 million in recoveries, fines/penalties, potential savings, questioned costs, or funds which could be put to better use during this reporting period. Our staff continues to provide wide coverage of the many programs and operations of a very diverse and complex organization. TVA, the nation's largest public power company, produces power through its fossil, hydroelectric, nuclear, and green power facilities for a seven-state region; revenues from power sales total approximately $8 billion. The focus of the OIG continues to be one of promoting excellence across all of TVA's programs and operations.

...Historic Change to the Governance Structure...

This is my first report to TVA's newly constituted Board since the new Board members were sworn in on March 31, 2006. Legislation signed by President Bush in 2004 expanded the Board from three full-time members to nine part-time members, with a full-time chief executive officer to run TVA on a day-to-day basis. As has been noted by many, this is a historic change to the governance structure of TVA.
