High-Performance Oil Reduces Varnish and Saves Money for Gas Turbine Power Plant

Varnish buildup in oil systems and components can degrade performance and cause erratic valve operation. Some experts have conducted research and formulated new lubricants that could help solve those problems. One such oil proved highly successful during a five-year run at a gas turbine power plant. By eliminating the need for oil changes and valve maintenance at the site during the trial period, the oil even saved money compared to previously used formulations.

The formation of varnish by turbine oils is not a new phenomenon. However, it has become an intense topic of discussion over the last several years because of the resulting downtime, decrease in reliability, and loss of productivity it causes in the power industry. There are a few significant factors that contribute to this issue.

Dynamics Behind Varnish Formation

Through intense focus on asset reliability and operational efficiency, end users have begun to push limits and increase the performance of their power units. The same focus by original equipment manufacturers (OEMs) has led to higher performing equipment.…

As Trump Takes Over, Who Wields Power?

What do we know as of February 1 about key Trump appointees responsible for administering White House policies affecting the power generation industry? Not much.

As the Trump administration settles in, how his teams at energy and environment agencies will implement his policy agenda remains unclear, as does his agenda. At the end of January, none of the Trump nominees for key energy and environment jobs had won Senate confirmation. The Senate Environment and Natural Resources committee approved former Texas Governor Rick Perry to be Department of Energy (DOE) secretary, by a bipartisan vote of 16–7 (the committee consists of 12 Republicans and 11 Democrats). Ryan Zinke (R-Mont.) got the nod to head the Interior Department by a 16–6 vote. Neither nomination has been scheduled for full Senate consideration.

Rick Perry, a former governor of Texas, is Trump's pick as energy secretary.

Experts: If Clean Power Plan Perishes, GHG Regulation Almost Certain Under NAAQS Program

If the Clean Power Plan is scrapped or weakened, the Environmental Protection Agency (EPA) may be forced to regulate greenhouse gases (GHGs) emitted by existing power plant with wider repercussions under its National Ambient Air Quality Standards (NAAQS) program, experts have warned.

While President-Elect Donald Trump promised to “scrap” the Clean Power Plan during his presidential campaign, the power sector has grappled with regulatory uncertainty since the Supreme Court issued a stay of the rule that establishes the first federal GHG limits for existing fossil fuel–fired power plants in February 2016. The rule, finalized in 2015 under Section 111 (d) of the Clean Air Act, has deeply divided the nation and U.S. power sector.

Eighteen states (plus the District of Columbia) supported the rule in the merits litigation: California, Connecticut, Delaware, District of Columbia, Hawaii, Illinois, Iowa, Maine, Maryland, Massachusetts, Minnesota, New Hampshire, New Mexico, New York, Oregon, Rhode Island, Virginia, Vermont, and Washington. A number of power companies are also participating as intervenors, including Calpine, Pacific Gas & Electric, NextEra, and Southern California Edison Co.…

Natural Gas and Wind Are Cheapest Sources of Power in Majority of U.S.

In a finding that is likely to boost controversy over the future of U.S. energy policy, a comprehensive study of the full levelized cost of energy (LCOE) from various sources of electricity conducted by the University of Texas (UT) at Austin’s Energy Institute found that wind turbines and natural gas combined cycle power plants (CCPPs) provide the least expensive options for new generation across a large majority of U.S. counties.

The study, “New U.S. Power Costs: By County, with Environmental Externalities,” is part of an ongoing initiative at UT that attempts to take a “holistic approach” to calculating both direct and indirect costs of generating electricity.

The Institute has placed the results online in the form of an interactive tool that allows comparison of the LCOE for various options and adjustment of fuel costs. (The tool also makes some assumptions about the suitability of certain generation in various locations; for example, there are areas that would be unsuitable for fossil plants for environmental reasons.)…

Arrests Made After Scaffold Collapse Kills 74 Workers at Chinese Power Plant

Nine people, including the chairman and chief engineer of the Fengcheng power plant, have been arrested following a scaffold collapse that killed 74 construction workers on November 24.

The scaffold platform had been erected to facilitate work on a cooling tower that was being constructed at the plant located in Yichun City, Jiangxi Province. According to a CCTV newscast, more than 60 people were working on the platform, and more than a dozen were on the ground waiting for their 7 a.m. shift to start, when the scaffold collapsed.

China’s state news agency Xinhua reported that the victims ranged in age from 23 to 53 years old, with most under the age of 36. More than 300 rescuers, two drones, four sniffer dogs, and seven cranes were said to have been involved in the search and rescue effort.…
