In the May issue, we discussed the importance of either preventing copper plating of the high-pressure (HP) steam turbine rotor or finding a good foam or mechanical removal means of restoring lost efficiency. In that article we noted that “copper deposits typically form on the stationary nozzle block or first-stage stationary blades” and that those deposits usually result in a steam turbine loss of capacity at a rate of about 2 to 3 MW per month. We also stated that the “general rule of thumb is that there is a reduction of about 1 MW of generating capacity for each 1 to 2 pounds of deposit that accumulates on the HP turbine.

In the past few years, nuclear concerns, rising oil prices, and a growing understanding of our environmental impact has given energy issues a higher profile worldwide. In this report on the Continental Nordic countries, we look at the efforts being made in much of the Nordic region to secure a sustainable energy supply for the future and at the extent to which the innovative solutions of these countries can be exported around the globe.

Understanding the reliability and failure mechanisms of photovoltaic modules is crucial to understanding how well they will perform over time. But today there are no test standards in place to judge this crucial issue.

This is the fourth in a series of predictive maintenance (PdM) articles that began in the April “Focus on O&M” with an introduction to PdM as a process whereby maintenance is performed based on the condition of the equipment rather than on a predetermined interval. In the May and July issues, we began exploring specific PdM techniques, such as motor-current signature analysis and oil analysis.

One of the great successes of the power generation industry over the past two decades has been the significant increase in nuclear plant reliability and other performance standards. However, there is reason to be concerned that the design, operation, and maintenance practices used by the current fleet of plants do not leverage all the possible advantages from a digital controls upgrade. Perhaps past success is the biggest barrier to future success.

Cloud computing is a growing phenomenon for many businesses, large and small, promising significant efficiencies and cost savings. But, as with anything new, computing in the cloud poses some unforeseen legal issues.

A new rule enacted by the Federal Energy Regulatory Commission (FERC) on Thursday orders organized wholesale power market operators to pay “just and reasonable rates” for providers of regulation service, an ancillary transmission service that protects the grid by correcting deviations in grid frequency and balance on transmission lines with neighboring systems.

An Alberta court on Friday rejected an environmental group’s challenge to the August-issued Alberta Utility Commission approval of a planned 500-MW supercritical coal-fired addition at the 150-MW H.R. Milner Generating Station in the Grande Cache area. The court’s decision paves the way for Maxim Power to begin construction of the controversial unit—the first coal plant built in the province in a decade.

After three years of development, dozens of public workshops, and hundreds of meetings with stakeholders, the California Air Resources Board (ARB) on Thursday adopted a final rule to cap California’s greenhouse gas emissions and put a price on carbon. The cap-and-trade program starts in 2013 for electric utilities and large industrial facilities.

Florida’s Public Service Commission (PSC) on Monday approved cost recovery amounts for construction of new nuclear power facilities and additions to existing nuclear plants planned by Progress Energy Florida and Florida Power & Light Co. (FPL). The decision would help secure “a diversified and stable energy future for Florida,” regulators said.

Surging coal prices have continued to prompt generators to displace some coal used for power generation with natural gas, and gas demand is again expected to jump this winter, which could pose some supply restraints, the Federal Energy Regulatory Commission (FERC) said in its Winter 2011-2012 Energy Market Assessment.

The Department of Energy (DOE) is seeking contenders for a three-year-long funding opportunity for applied scientific research to advance novel concentrating solar power (CSP) technologies. The $60 million investment is part of the DOE’s SunShot Initiative, a collaborative effort to reduce the cost of solar energy 75% and make it cost competitive with other forms of energy by the end of the decade.

A companion bill to the U.S. House’s recently passed Coal Residuals Reuse and Management Act (H.R. 2273) was last week introduced in the Senate by Sens. John Hoeven (R-N.D.) and Kent Conrad (D-N.D.).

The U.S. House of Representatives on Thursday passed The Environmental Protection Agency (EPA) Regulatory Relief Act of 2011 (H.R. 2250) by a vote of 275-42 .The bill, which seeks to limit the federal agency’s rules limiting toxic air pollutants from commercial and industrial boilers and thwart the EPA from proposing a new standard for at least 15 months after enactment, now heads to the Senate, where it is unlikely to pass, industry analysts say.

On Friday, following passage of a bill to delay Environmental Protection Agency (EPA)–promulgated Boiler MACT rules, the U.S. House of Representatives also passed the Coal Residuals Reuse and Management Act (H.R. 2273), legislation that would impede the federal agency from proceeding with its May 2010 proposed rule to regulate coal ash residuals.

An association of 41 European transmission system operators (TSOs) from 34 countries last week warned that adequacy margins in the coming winter could dip dangerously and threaten power supply for most of the continent.

A coalition of seven U.S. manufacturers of solar cells and panels today petitioned the U.S. International Trade Commission (ITC) to investigate whether Chinese manufacturers are illegally dumping crystalline silicon solar cells into the U.S. market and receiving illegal subsidies from China. The measure follows a string of bankruptcy filings by several U.S. solar manufacturers in the past few months.

New variants of Stuxnet—the sophisticated computer virus designed to attack control systems and which was used last year to sabotage the Iranian Bushehr nuclear power plant—has been detected in European computer systems. The malware, dubbed “Duqu” is “essentially the precursor to a future Stuxnet-like attack,” computer security firm Symantec said on Tuesday.

A study conducted by the New York Independent System Operator Inc. (NYISO) to evaluate whether the cost of compliance with the Regional Greenhouse Gas Initiative (RGGI)—a regional cap-and-trade program—has caused an increase in greenhouse gas (GHG) emissions in neighboring non-RGGI areas such as Pennsylvania concluded RGGI has not caused an increase in emissions or significantly affected the pattern of power supply.

The U.S. Department of Agriculture (USDA) on Thursday announced approvals of loans worth $2.1 billion to 43 projects in 27 states that would help rural electric utilities build and upgrade infrastructure in rural America.

Heavy rain in key mining areas in India has caused a critical coal shortage and restricted supplies to several major coal-fired power plants in the nation that fuels 55% of its power capacity with coal.

By Kennedy Maize Washington, D.C., October 18, 2011 — Remember the flap about inconsistencies between the Energy Information Administration and the U.S. Geological Survey over shale gas estimates for the Marcellus formation? Forget about it. According to a new paper from the Washington think tank Resources for the Future, there’s no discrepancy at all: the […]

By Kennedy Maize Washington, D.C., October 17, 2011 – To describe Progress Energy’s Crystal River nuclear power plant on Florida’s west coast as a problem unit is a substantial understatement. Commissioned in 1977, the 838-MW Babcock & Wilcox pressurized water reactor has been one of nuclear’s Poor Pitiful Pearls for the past few years. Currently, […]

The start of operations at the Finnish utility Teollisuuden Voima’s (TVO’s) Olkiluoto 3 nuclear power plant, Europe’s first EPR, which is under construction in Finland, could be postponed until 2014. The $4 billion project, originally due to come online in 2009, is years behind schedule and has been consistently plagued with faulty materials and planning problems since construction began in 2005.

Georgia Attorney General Sam Olens on Thursday filed suit against the Environmental Protection Agency’s (EPA’s) Cross-State Air Pollution Rule (CSAPR), which was finalized by the EPA this summer. On Monday, Xcel Energy also filed suit against the EPA, asking the agency to reconsider its methodology for calculating allowable emissions.

Instead of transferring to the Federal Energy Regulatory Commission (FERC) its authority to conduct congestion studies and establish a process for designating national transmission corridors under section 216 of the Federal Power Act (FPA), as it was considering last month, Energy Secretary Steven Chu said the Department of Energy would work “more closely” with FERC in reviewing new transmission projects.

An analysis released by ISO New England on Thursday identifies several challenges that could dramatically change New England’s grid, including the retirement of generators and the integration of renewable resources.
