Xcel Energy announced on Friday that it has reached a settlement with the federal government regarding costs incurred by Northern States Power Co. (NSP) and its customers because of the Department of Energy’s failure to begin removing used fuel from the company’s nuclear plant sites by a 1998 deadline. As a result, over $100 million will be returned to NSP customers in five states.

The Republican-led House Appropriation Committee on Monday approved an annual spending bill for fiscal year 2012 that would cut funding for the U.S. Environmental Protection Agency (EPA) to $7.1 billion—18% less than requested. The bill would also suspend existing federal rules that limit greenhouse gas (GHG) emissions from stationary sources, prohibit the agency from issuing any rules limiting GHG emissions from stationary sources, and from issuing permits containing provisions to limit GHGs emissions from stationary sources during the next fiscal year.

The Canadian province of Québec last week issued draft rules for the operations of a greenhouse gas (GHG) cap-and-trade program based on guidelines from the Western Climate Initiative (WCI), of which it is a member. The draft regulation, now open for a 60-day public comment period, covers emissions of more than 25,000 tons of carbon dioxide per year, and it applies to power sector and industrial emitters. If the rules go into effect, the province could have a working cap-and-trade program by Jan. 1, 2012.

New Hampshire’s Gov. John Lynch last week vetoed a bill that would have withdrawn the state from the Regional Greenhouse Gas Initiative (RGGI), a regional carbon trading program whose members include nine other Northeastern and Mid-Atlantic states. The governor said the bill would cost the state’s citizens jobs and hinder economic recovery.

Australia’s coal-fired power plants will have access to emergency federal loans to prevent financial failure and ensure power supplies. The government move is in response to a carbon tax set to be announced on Sunday.

Atomic Energy of Canada Ltd.’s (AECL’s) CANDU reactor division is to be sold to Canadian engineering firm SNC-Lavalin Group Inc. for C$15 million Canada’s natural resources minister, Joe Oliver, announced last Wednesday.

Last Thursday, U.S. Energy Secretary Steven Chu announced offers of conditional commitments for loan guarantees of approximately $4.5 billion to support three alternating current cadmium telluride (Cd-Te) thin film photovoltaic (PV) solar generation facilities.

An explosion and fire at a French nuclear plant and jellyfish clogging Scottish and Israeli cooling water intakes were added to the list of challenges faced by nuclear and coal generators in the past week.

Last Wednesday, worsening flooding conditions along the Missouri River prompted the partial evacuation of nonessential workers from the Iatan Power Plant in Weston, Missouri, 40 miles north of Kansas City. The plant remains in operation.

For the first time in 37 years, the Japanese government ordered large customers to restrict electricity usage if they are in Tohoku Electric Power Co. Inc.’s or Tokyo Electric Power Co.’s (TEPCO’s) service territories, effective July 1. With the exception of essential services and powering cleanup operations at the destroyed Fukushima Daiichi nuclear plant, large energy users are to cut consumption 15% below last summer’s levels.

The U.S. Mine Safety and Health Administration (MSHA) announced last Wednesday that it has determined that Massey Energy officials kept two sets of safety records for the Upper Big Branch Mine (UBB) in Raleigh County, W.Va., site of a deadly explosion a year ago. Additional details, including evidence that miners faced intimidation that prompted them to ignore safety hazards, point to the conclusion that the accident last spring was preventable.

Last week, New Jersey’s Legislature passed legislation that affirmed the state’s involvement in the Regional Greenhouse Gas Initiative (RGGI) and banned the natural gas drilling technique known as hydraulic fracturing, or fracking. Neighboring New York, meanwhile, is poised to lift a moratorium on new shale gas drilling, and France has become the first country to ban fracking.

On June 30, the Nuclear Regulatory Commission (NRC) approved PSEG Nuclear’s request to extend the operating licenses of Salem Generating Station Units 1 and 2 an additional 20 years. The decision was met by protests from environmentalists, who say that PSEG Nuclear has done too little to address leaks at the plant.

This installment of the series continues our review of different conditioning-monitoring techniques commonly in use at power plants using any generation technology. In the May issue we began exploring specific PdM techniques with an examination of electrical surge comparison and motor-current signature analysis.

Eclipse Inc. introduced the TJSR v5 self-recuperative burner for direct-fired furnace heating applications. The advanced burner design combines a high-velocity flame with fuel-saving recuperation. A space-saving integral eductor pulls the furnace exhaust through an internal ceramic recuperator. The recuperator preheats the incoming combustion air to very high levels, which improves furnace operating efficiency to reduce […]

It may seem counterintuitive, but the strategic coupling of simple- and combined- cycle technologies with renewable generation could establish the conditions necessary for adding more renewable megawatts to transmission grids around the world.

Massachusetts-based Cabot Corp. recently introduced Enova, an aerogel that is a new high-performance thermal additive designed specifically for insulation coatings. Enova aerogel is designed for application to surfaces that are not already insulated but ideally should be. Cabot researchers have found that applying a 1-millimeter coating containing Enova aerogel to a 200C metal surface meets […]

Underground coal gasification (UCG) is the gasification of coal in-situ, which involves drilling boreholes into the coal and injecting water/air or water/oxygen mixtures. It combines an extraction process and a conversion process into one step, producing a high-quality, affordable synthetic gas, which can be used for power generation. Still in the early stage of commercialization, UCG is poised to become a future major contributor to the energy mix in countries around the world.

Distributed wind generator supplier Southwest Windpower unveiled a small wind turbine for commercial and residential use, the Skystream 600, which it claims is the “most efficient power grid-connected turbine in its class, providing an average of 7,400 kWh of clean, low-cost energy per year per household in 12 mph average annual wind speeds.” The company […]

Is the term "energy independence" merely an oxymoron, or is it a national imperative? Opinions differ. Either way, the goal is practically impossible to achieve.

When President Obama unveiled his “clean energy standard” in the 2011 State of the Union address in February, and again when he spoke of his administration’s energy policy in late March, one form of electrical energy was conspicuous by its absence: hydropower. Hydro is the forgotten form, the politically incorrect renewable, the invisible generation. To borrow the complaint of comedian and Caddyshack movie star Rodney Dangerfield, hydro projects “don’t get no respect.”

Encorp LLC announced the launch of its Microgrid System Controller, which it says is the industry’s first microgrid system controller to connect onsite synchronous generators with renewable energy assets—such as photovoltaic systems, wind, and microturbines—and then monitor and control the resulting microgrid. The controller has already been successfully installed at a major international defense contractor […]

Both the 1979 Three Mile Island accident and the Chernobyl catastrophe prompted worldwide retreats away from nuclear electric generating technologies. Despite brave rhetoric from nuclear supporters around the world, a number of countries with a large number of nuclear plants are having second thoughts about the future of nuclear power.

Four concrete cooling towers at a coal-fired electrical generation plant exhibited reinforcing steel corrosion that was causing concrete deterioration. This case study follows the repairs to those towers—how the corrosion control solution was selected, how repairs were made, and how follow-up tests found the repairs to be effective three years later.

Thomas & Betts’ Emergi-Lite Nexus Emergency Lighting Management System provides real-time status of the entire emergency lighting and exit-sign system, runs system diagnostics, performs required monthly and annual functional tests, generates maintenance logs, and runs compliance reports from a central control unit. Additionally, the system operates independently of the emergency lighting and exit sign, so […]

How easy is it to hack a generator’s SCADA system? It’s so easy it scares the heck out of the guy who used to run network security for the Bonneville Power Administration. It’s so easy he can’t tell us any details, for security reasons. That’s why we should all be scared.

David K. Owens, executive vice president, Business Operations Group for the Edison Electric Institute, comments on the progress U.S. utilities are making toward a smarter electrical power grid.

At the close of 2009, the U.S. geothermal industry had seen seven new geothermal power plants come online in the previous 12 months. In 2010, only one new power plant was completed.

The Federal Energy Regulatory Commission is starting to sort out the often mysterious and vexing issues surrounding reliability penalties as the federal agency and the North American Electric Reliability Corp. work through their evolving relationship. The case involves an outage at the Turlock Irrigation District in California.

FERC has surrendered jurisdiction over station power in California, putting merchant generators nationwide at risk of disadvantage to utility generators.
