The Tennessee Valley Authority is a federally owned corporation in the United States created by congressional charter in May 1933 to provide navigation, flood control, electricity generation, fertilizer manufacturing, and economic development in the Tennessee Valley, a region particularly affected by the Great Depression. The enterprise was a result of the efforts of Senator George W. Norris of Nebraska. TVA was envisioned not only as a provider, but also as a regional economic development agency that would use federal experts and electricity to rapidly modernize the region's economy and society.TVA's service area covers most of Tennessee, portions of Alabama, Mississippi, and Kentucky, and small slices of Georgia, North Carolina, and Virginia. It was the first large regional planning agency of the federal government and remains the largest. Under the leadership of David Lilienthal , TVA became a model for America's governmental efforts to seek to assist in the modernization of agrarian societies in the developing world. Wikipedia.

The American Wind Energy Association will release its much anticipated annual report on April 12, and the group’s CEO Tom Kiernan provided CleanTechnica with some advance insights during a one-on-one phone chat last week. Hint: it’s gonna be big. Kiernan also discussed two recent major milestone developments in the US wind industry, one being the construction of the nation’s first ever offshore wind farm — which will finally open the floodgates to developing the immense Atlantic Coast wind resources — and the other involving the Energy Department in what will be the biggest ever renewable energy project in the US. AWEA has already teased some info for its 2015 annual wind energy report to the press, underscoring the sector’s reduction in carbon dioxide, sulfur dioxide, and nitrogen emissions: Electricity generated by wind in 2015 displaced an estimated 176,000 metric tons of SO2 and 106,000 metric tons of NOx, representing $7.3 billion in avoided health costs last year alone. AWEA provides third-party statistics that suggest wind sector growth has contributed to a total US power sector emissions drop down to 1995 levels, while average electricity rates dropped — yes, dropped — 5.5 percent below 2009. The group also states that “wind energy is the most cost-effective energy source to comply with the Clean Power Plan” put forth by President Obama last summer, and in the interview Kiernan emphasized that wind also provides the US with a pathway for honoring its Paris COP21 global climate pledge. Among other tidbits, AWEA’s 2015 statistics reveal that the US is now #1 in global wind energy production. During his conversation with CleanTechnica, Kiernan provided this additional teaser for the 2015 report: There will be some exciting news about jobs growth…for example wind technicians [maintenance, service and repair positions] is now the fastest-growing profession in the country… The group has also has some big news about private sector, non-utility wind investments and it has scheduled another preview announcement about the report for April 7, so stay tuned for that. CleanTechnica’s conversation with Kiernan began with a discussion of the soon-to-be-completed Block Island wind farm off the coast of Rhode Island. Offshore wind energy development faces some technological challenges compared to onshore, so getting “steel in the water” is a major development for the industry: It’s a very important step to prove the opportunities for offshore wind in the US…it’s beginning to build infrastructure and momentum for the industry… The cost of onshore wind has dropped 66 percent in the last four years according to Kiernan, and he foresees a similar pattern in the offshore sector: Offshore is a very new industry…some of the early pioneering projects will establish ports and supply chains, and attract workers to the industry… As Kiernan sees it, Block Island has finally established the US as a serious player in the offshore sector. That will attract serious global investors such as Dong Energy, and access to global technological improvements will also help to drive down costs. Things won’t happen overnight, but Kiernan does anticipate steady progress for offshore wind in the US, especially after Block Island starts producing clean electricity: There are many steps in the [offshore development] process. It’s a complicated, multi-tiered effort and it’s important to have federal support… This project will inspire even more public support…it’s inspirational and exciting. We’re on the cusp of significant new clean energy development off the East Coast. The other big development is the Energy Department’s announcement that it will get behind the proposed 700-mile megawatt Clean Line Plains & Eastern transmission line, designed primarily to transport electricity from Oklahoma and Texas wind farms through Arkansas to Tennessee and points east. At 4,000 megawatts, Plains & Eastern counts as the biggest renewable energy project so far in US history. By way of comparison, the Hoover Dam hydropower plant clocks in at 2,000 megawatts of capacity. The other striking thing about the project is the Energy Department approval (check out the Tennessee Valley Authority for an idea of the scale and impact of major federally sanctioned energy initiatives). As described by Kiernan, federal involvement provides wind with the same procedural advantages that other conventional forms of energy have long enjoyed: It’s important for building momentum for [wind] transmission projects throughout the country…conventional power has long term, proven regulatory processes that are speedier. This is the first one for clean energy…it’s a very important step for the industry. This is a transformational project. Kiernan also noted that onshore wind energy leases provide farmers and ranchers with a zero-water “cash crop.” That’s a major advantage over conventional power in areas where water resources are stretched thin. According to AWEA’s statistics, wind leases currently pump $220 million per year into the rural economy, making wind energy a significant source of local income as well as a rural jobs generator — all while contributing to a shrinking carbon footprint for the US economy. Those are good points to keep in mind when clean energy projects raise eminent domain and good-neighbor issues as well as environmental issues. No form of energy development is impact free, but a legitimate case can be made that the benefits and consequences of clean energy projects outweigh the impacts. Speaking of impacts, the spectacular growth of the US wind energy industry is all the more spectacular considering what happened before and after 2009. Before 2008, the US wind energy industry was a tiny sector that received strong bi-partisan support for future growth. Beginning in 1992, it was nourished along with a series of routinely passed federal tax breaks, just as other domestic energy sectors — oil, gas, coal and nuclear — were established thanks to supportive federal energy policies. After President Obama took office in 2009, the production tax credit for wind could still claim Republican support thanks to longtime wind advocate and Nebraska Senator Chuck Grassley (yes, this guy), but the renewal of the tax break transformed from a routine transaction to a huge bone of contention thanks partly to a comprehensive state-level campaign against renewable energy spearheaded by the Koch-backed lobbying organization ALEC. Anti-wind efforts along the Atlantic coast were also aided directly by Koch family members in the case of Cape Wind, which would have been the nation’s first offshore wind farm, and indirectly by East Coast governors within the Koch family sphere of influence. Wind industry growth took a stumble a couple of years ago while Republican leadership in Congress dithered over approval of the tax credit, but in the latest development a last-minute agreement in December 2015 is keeping it alive through 2016. That doesn’t necessarily mean it’s clear sailing for the US wind industry from here on out, but between Block Island and the Plains & Eastern line, it’s going to be very difficult to step backwards from here.

The charges against a U.S. citizen come, strangely, just as the Department of Energy is collaborating with China on advanced reactors. In a case that sounds like the plot of an espionage novel, a naturalized U.S. citizen born in China was indicted last week on charges of illegally sharing information on commercial nuclear reactors with a major Chinese nuclear power company. The nuclear engineer, Szuhsiung “Allen” Ho, recruited a ring of nuclear engineers—unnamed in the indictment—to “unlawfully engage and participate in the production and development of special nuclear material outside the United States” and to help develop China General Nuclear Power Company’s ACPR-100, a small modular reactor design, and provide computer codes for modeling reactor operations. The engineers, one of whom was a senior manager at the Tennessee Valley Authority, were paid by China General, through Ho, according to the indictment, but it is not clear whether they understood that Ho was breaking the law. The charges come just two weeks after the White House hosted a summit on nuclear security that was attended by Chinese head of state Xi Jinping. “Budget is no issue,” Ho wrote to one of the engineers in an e-mail quoted in the indictment. China General Nuclear Power is also charged, along with Ho, with violating the Atomic Energy Act. The illegal technology transfers allegedly went on for nearly two decades. Many of the details of this extraordinary case, including just how the U.S. Department of Justice plans to prosecute a Chinese company, are not yet clear. Two aspects, however, are worth highlighting. First, as Bloomberg points out, China General is a state-owned corporation and a key player in China’s drive to become a leading supplier of nuclear reactors and components around the world. China General recently established a joint venture with China National Nuclear Corporation, another state-owned enterprise, to build at least 30 Hualong One reactors, a home-grown design, in Asia and Europe. Secondly, the charges against Ho and China General come even as the U.S. Department of Energy is actively collaborating with the Chinese Academy of Science on advanced reactor designs. Ho’s activities were unauthorized and, as such, illegal. But it’s important to note that even as the U.S. government is prosecuting a citizen for conspiring to “secure an advantage to the People’s Republic of China,” another federal agency is helping China’s nuclear power R&D program.

Integrated Environmental Assessment and Management | Year: 2015
A baseline ecological risk assessment (BERA) was performed for residual ash in theWatts Bar Reservoir following a release of fly ash from the Tennessee Valley Authority (TVA) Kingston Fossil Plant. The site consists of parts of 3 rivers in eastern Tennessee comprising over 32 river kilometers. The purpose of the assessment was to determine if residual ash negatively impacts maintenance and reproduction of balanced communities or populations of potentially exposed ecological receptor groups in these rivers. This introductory article summarizes the site and environmental setting, assessment and measurement endpoints, risk characterization methods, and the study approach. Subsequent articles describe ecological risks to fish, benthic invertebrates, aquatic- and riparian-feeding wildlife, and aerial-feeding insectivores; and the role ecological risk characterization played in determining the most effective management of the residual ash, setting project remediation objectives and targets, and designing long-term monitoring to measure the effectiveness of the selected removal action. © 2014 SETAC.
