Switzerland-based ABB today announced that it has developed the world’s first circuit breaker for high voltage direct current (HVDC), solving what it says has been “a 100-year-old electrical engineering puzzle and paving the way for a more efficient and reliable electricity supply system.” The breakthrough holds promise not just for renewables development but also for all types of generation that nations and regions wish to transmit over long distances, including under large bodies of water.

Tuesday saw the re-election of President Barack Obama, Democrats boosting their numbers in the U.S. Senate, and Republicans retaining their majority in the House. Voters in several states also cast ballots to decide a variety of environmental and energy issues at state and local levels. The results included rejection of a proposed raising of Michigan’s renewable energy standard (RES) to 25% by 2020 and passage of closing a tax loophole for out-of-state corporations in California to fund clean energy and energy efficiency projects.

An explosion at a 600-MW coal/biomass power plant in the eastern Netherlands city of Nijmegen early on Thursday morning sent steam clouds into the sky, scattered ceramic wool in the vicinity, and prompted police to advise nearby residents to keep their windows and doors shut. No casualties were reported, and all workers are accounted for, said GDF Suez, whose subsidiary Electrabel owns the plant.

South Korea’s government on Monday shut down two nuclear reactors at the Yeonggwang nuclear complex owned by the state-owned Korea Hydro & Nuclear Power Co. (KHNP), which it said were equipped with thousands of parts allegedly linked to forged quality and safety warranties.

Several nuclear power plants in the path of Hurricane Sandy, the "superstorm" that devastated parts of the East Coast last week, endured the hurricane-force winds and storm surges without significant impact, the Nuclear Regulatory Commission (NRC) has said.

Dominion Virginia Power on Friday asked the Virginia State Corporation Commission (SCC) to approve construction of a 1,358-MW combined cycle natural gas-fired power plant to replace power from aging coal plants that the company has deemed are not economically or environmentally sound to continue operating.

The International Trade Commission (ITC) on Wednesday unanimously determined that imports of crystalline silicon photovoltaic cells and modules from China materially injured the U.S. industry, clearing the way for the Commerce Department to issue antidumping and countervailing duties on billions of dollars of products from China for the next five years. However, the ITC’s determination finds no critical circumstances were present, which means duties on Chinese solar module imports won’t apply retroactively.

By Kennedy Maize (@kennedymaize) Washington, D.C., 7 November, 2012 — With Barack Obama given another four-year lease on 1600 Pennsylvania Avenue, the policy and regulatory landscape for the electricity business is largely unchanged. But the roadmap may be somewhat different. Obama’s reelection represents neither an endorsement nor a repudiation of his policy initiatives on such […]

A “who’s doing what” addendum to "THE BIG PICTURE: Advanced Fission" in our November 2012 issue.

Renewable energy projects installed on potentially contaminated lands, landfills, and mine sites have increased by 40% since 2008, a new list released last week by the Environmental Protection Agency (EPA) shows. Solar photovoltaic (PV) systems make up the bulk of about 184.7 MW installed at 60 sites in 25 U.S. states.

Surging supplies of natural gas have led to serious discussions of exporting this resource. The head of APGA explains how this threatens the U.S.’s long-term interests and energy security.

The power-hungry ERCOT region is getting an upgrade, as Siemens and Bechtel are building two advanced combined cycle plants in central Texas.

When the Albany area needed a new power plant, pulling water from the Hudson River would have been the easy choice. But the plant owners chose to get creative, drawing on a convenient but unconventional source for their cooling water.

When you’re building a natural gas pipeline, running pipe from Point A to Point B is only the final, most obvious step. You’ve got to jump through a lot of hoops to get there, in a process that can take years and that involves a lot of foresight.

Bigger isn’t always better, but when you’ve got big power needs in a remote location, your options are often limited. A new mobile gas-fired generator aims to change that, offering both big capacity and a small footprint.

The shale boom has run well ahead of the infrastructure needed to handle all the production. When there’s nowhere to put associated gas, much of it is being flared. But this common industry practice is starting to draw some uncommon attention.

This year’s healthy growth in global gas-fired power generation continued in the third quarter, with significant projects being planned in Turkey and Japan.

The Electric Power Research Institute and several partners—including the Southern Research Institute, Southern Co. subsidiary Georgia Power, and Southern Research—are testing a new technology that could reduce the amount of water needed for power plant cooling.

On Tuesday morning, half a day after Hurricane Sandy made landfall in New Jersey, the enormous storm, now being called a superstorm or a post-tropical cyclone, was still causing destruction far inland while as many as 6 million electric customers from Maine to North Carolina and west to Pennsylvania and West Virginia were without power.

Four coal and two oil generating units at two of the oldest power plants owned by Santee Cooper are to be retired. South Carolina’s state-owned utility said last week that the decision was reached by its board of directors after considering generation resource needs and the cost of complying with new environmental regulations.

Global Companies Take on Nigeria’s Newly Privatized Plants. Nigeria’s $1 billion liquidation of five government-owned thermal and hydropower generation companies—part of a wider privatization effort that includes transmission and distribution assets to encourage investment in the power shortage–stricken country’s electricity sector—has attracted a number of global companies and investors. Eight firms bid a total of […]

Natural gas–fired generation gave up some ground to coal during the third quarter, and coal producers are optimistic that higher natural gas prices will benefit coal, especially coal sourced from the Powder River Basin in Wyoming. Even so, at least one Midwest utility expects natural gas to power what could be as much as 1,500 MW of new generating capacity it may add over the next several years.

In a bid to encourage construction of new power plants in power-strapped Texas, the state’s Public Utility Commission (PUC) last week voted to double the wholesale price cap for electricity prices by the summer of 2015.

When a nuclear power plant experiences ground motion due to an earthquake, an evaluation may be needed before allowing the plant to continue operating or to resume operating if it has been shut down, as was the case after the seismic event that shut down both units at Dominion’s North Anna Power Station on August 23, 2011.

Hitachi announced on Tuesday that it had acquired Horizon Nuclear Power in a deal expected to be completed by the end of November. In another example of the global nature of the nuclear business, the Japanese firm purchased Horizon, which was developed by the UK to build new nuclear plants, from German companies RWE and E.ON.

The first quarterly update from the Tennessee Valley Authority (TVA) reporting construction progress of the Watts Bar Unit 2 nuclear reactor suggests that the project is on track for completion between September and December of 2015 and is within its budgeted cost range of $4 billion to $4.5 billion.

All turbo machinery is subject to degradation that, over time, will affect the system’s efficiency and operational performance. Precise monitoring of turbo machinery performance with continuous torque-monitoring systems can be used to identify gradual efficiency loss. That, in turn, allows a more focused maintenance scope to be developed that can return the system to its optimum operation and efficiency.

China regards nuclear energy as a critical part of its strategic goal of achieving sustainable economic development while reducing environmental pollution. An analysis by North China Electric Power University predicts that the pace of nuclear power development may slow for a short time as a result of the Fukushima accident, but nuclear power is still a top development priority.
