A federal district court judge on Tuesday ruled that the Rural Utilities Service (RUS), an arm of the U.S. Department of Agriculture (USDA), must complete an environmental impact study (EIS) before any approvals or other major federal action can be taken on the $2.8 billion expansion at Sunflower Electric Power Corp.’s coal plant in Holcombe, Kansas. The ruling may delay construction of the 875-MW plant, a politically controversial project in the Kansas Legislature.

The expectation of millions of "green jobs" has disappeared from public debate. Today, the debate is narrowly focused on "jobs" and selecting the best approach to developing permanent jobs, regardless of color. Some look to the government to create jobs through regulation or subsidy, and others trust companies operating under free market principles to create permanent jobs.

Federal Energy Regulatory Commission (FERC) on Monday released a white paper that seeks comment on its proposals to “provide a fair, timely and transparent process” for FERC to advise the Environmental Protection Agency (EPA) on requests for extension of time to comply with its Mercury and Air Toxics Standards rule.

The U.S. Environmental Protection Agency’s (EPA’s) new Mercury and Air Toxics Standards (MATS) rule for power plants has critics’ tempers flaring. Not surprisingly, a number of electric power representatives, industry groups, and elected officials oppose the rule, which was released on Dec. 21, 2011.

The electric power generation system is the backbone of our economy. Recently, however, sudden outages or rolling blackouts have increased.

Handheld smart devices providing custom applications and Internet access at the touch of a virtual button are common today. Hidden beneath their touchscreens is a global network of digital technologies that respond to each command. Will these familiar commercial technologies and apps make their way to industrial digital control systems?

Asset management means different things to different people. But it boils down to converting raw data and observations about equipment and components into information and knowledge that is then used, propagated, and shared by workers and digital components to manage performance. Nuclear plants have special asset management needs, given the level of their safety, reliability, and regulatory requirements.

When then-President George W. Bush signed the Energy Independence and Security Act of 2007, he noted that, “New technologies will help usher in a better quality of life for our citizens.” One provision of the act required an increase in the efficiency of newly manufactured lightbulbs, starting with 100-watt incandescent bulbs in 2012.

The consideration of power supplies has become critical to the success of converting analog instrumentation and control systems to digital control systems (DCSs). Careful planning is particularly necessary for nuclear power plants, where instrumentation systems are required for safely shutting down a reactor, mitigating the consequences of an accident, and performing post-accident analysis.

Of the $35.9 billion in loan guarantees awarded by the U.S. Department of Energy (DOE) since 2009, roughly $26.5 billion have financed nuclear and renewable power projects across the nation through the Section 1703 and 1705 loan guarantee programs.

Brazil’s power industry has long been dominated by its vast hydro resources, which historically have accounted for over 80% of the country’s generation capacity. With engineering marvels like the massive Itaipú dam and the proposed Belo Monte project, the country is a leader in the development and use of hydroelectricity on a grand scale. But as the 2001 energy crisis proved, dependence on a single source leaves the country vulnerable to severe shortages. Thanks to government programs designed to take advantage of the country’s favorable climate, Brazil is committed to diversifying its energy mix while continuing to maintain a renewable energy focus.
