For the first time in a decade, the Alberta Utilities Commission on Friday gave its final approval for building a coal-fired power plant. Maxim Power received approval to build and operate a new 500-MW coal-fired plant at the existing 150-MW H.R. Milner Generating Station in the Grande Cache area. The company had provided "credible evidence" that air emission issues have been addressed through plant design and other mitigation measures, the commission said.

Four research projects that could further carbon capture technologies—helping them achieve at least 90% carbon dioxide removal with no more than a 35% increase in power costs—were on Monday selected for further development by the Department of Energy’s Office of Fossil Energy.

The Department of Energy (DOE) on Monday finalized a $102 million loan guarantee to a 50.6-MW power plant and an 8-mile transmission line, right on the heels of Department of the Interior (DOI) approval for a massive 550-MW solar photovoltaic (PV) facility in California last week.

Sen. Charles Schumer (D-N.Y.) is reportedly floating legislation that could require Federal Bureau of Investigation (FBI) background checks for workers at all power plants and critical infrastructure plants with access to restricted areas.

The Tomari 3, a 912-MW pressurized water reactor (PWR) at Hokkaido Electric Power Co.’s Tomari plant in northern Japan’s Hokkaido region, has resumed full commercial operation. It is the first reactor in the country to be restarted after a periodic inspection following the March 11 earthquake and tsunami that caused the Fukushima nuclear disaster.

By Kennedy Maize Washington, D.C., August 15, 2011 — It’s about those polar bears. You know, the ones endangered by global warming turning the Arctic into Florida, the poster predators of man’s inhumanity to the Earth. Those cute figures who have graced Coca-Cola ads and memorabilia for decades. Well, maybe they aren’t that endangered after […]

By Kennedy Maize Washington, D.C., August 14, 2011 — I don’t often agree with former CIA director James Woolsey. In fact, I can’t think of a time that I have ever agreed with him. Until this week, that is, when Woolsey offered a short, sharp elbow to the policy ribs of the smart grid during […]

Two new AP1000 reactors proposed for the expansion of Plant Vogtle near Waynesboro, Ga., on Tuesday received a Final Safety Evaluation Report (FSER) from the Nuclear Regulatory Commission (NRC). In a major milestone for the project—the first two reactors that will be built in the U.S. in 25 years—the federal regulatory agency concluded there are no safety aspects that would preclude it from issuing a limited work authorization and combined construction and operating license (COL) for the project.

Five U.S. grid operators last week jointly urged the U.S. Environmental Protection Agency (EPA) to reconsider strict compliance deadlines proposed for a suite of rules because they feared "accelerated" generation retirements as owners assessed the costs of complying with them. The grid operators also asked the EPA to consider keeping some plants online if they met certain conditions, because taking them out of service would affect system reliability.

Power demand for the Electric Reliability Council of Texas (ERCOT) control area hit three consecutive records in the past week—reaching 68,294 MW on Aug. 3—forcing the grid operator to cut power to large industrial users to avoid rolling blackouts. It was the second time this year and only the fourth in more than two decades that the grid operator has been forced to implement such measures.

Eight days ahead of schedule, China on Sunday put into commercial operation Ling Ao Unit 4, the second facility of the Ling Ao Phase II nuclear power plant. Unit 4, owned by the state-owned China Guangdong Nuclear Power Co. (CGNPC), brings the number of reactors at the Ling Ao/Daya Bay Nuclear Power Base to six—making it China’s largest nuclear complex to date.

The Tennessee Valley Authority (TVA) on Monday said it would delay construction at Watts Bar Unit 2 and delay commercial operation of the facility from the previously anticipated late 2012 timeframe into 2013, owing to a licensing delay, safety and environmental issues, and a transition in the leadership of its nuclear generation development and construction (NGDC) group.

The Department of Energy (DOE) on Thursday finalized a $967 million loan guarantee for a solar photovoltaic facility in Arizona. On Tuesday, it also awarded $7 million for independent cost analyses supporting research and development for fuel cells and hydrogen storage systems.

Dynegy has restructured to create separate coal-fired and gas-fired power generation units.

On Friday, the Blue Ribbon Commission—Energy Secretary Steven Chu’s 15-member panel assigned to recommend a new plan for managing the back end of the nuclear fuel cycle—released a draft report for public comment. The public comment period is due to end Oct. 31, 2011, and a final report is due to Secretary Chu before Jan. 29, 2012.

The city of Chicago on Thursday reintroduced an ordinance that could shut down two coal-burning power plants in the city owned by Midwest Generation, an Edison International subsidiary.

The UK plans to shutter its Sellafield Mixed Oxide (MOX) plant (SMP) as soon as it is practically feasible because the March 2011 Japanese quake and subsequent nuclear crisis at Fukushima have changed the facility’s commercial risk profile, the Nuclear Decommissioning Authority (NDA) said today.

The Smart Grid Interoperability Panel (SGIP)—a consensus-based group of more than 675 public and private organizations created by the National Institute of Standards (NIST)—has made the first six entries into its new Catalog of Standards, a technical document that is expected to serve as a guide for smart grid–related technology.

The Yucca Mountain fracas last week became more intense as the National Association of Regulatory Utility Commissioners (NARUC) joined a coalition of state and local governments in a suit against the Nuclear Regulatory Commission (NRC). The petitioners claim the agency is “unreasonably delaying” a decision on the proposed—and now-defunct—permanent spent nuclear fuel repository in Nevada.

The share of electricity generated from coal in the U.S. during the first three months of this year was at its lowest first-quarter level in more than three decades—even though the overall total level of generation in the U.S. increased by a little less than 1%, the Energy Information Administration (EIA) reported last week.

Alberta’s provincial government last week signed a final funding agreement for a unique carbon capture and storage (CCS) project that seeks to tap a deep unmineable coalbed and turn the coal into power-generating synthetic gas—or “syngas”—while underground.

Plans have been delayed to build a small-scale coal gasification facility that would have enabled researchers from the University of Wyoming (UW) and GE Energy to understand the conversion of feedstock by gasification into syngas for use in power generation. The delay of at least 18 to 24 months stems from a lack of federal energy policy, Wyoming’s Governor Matt Mead said on Friday.

The Department of Energy on Tuesday announced a $50 million investment over two years for the SUNPATH program, an initiative that seeks to help the U.S. reclaim a competitive edge in solar technology manufacturing.

By Kennedy Maize Washington, D.C., August 1, 2011 — A recent article in the peer-reviewed journal Remote Sensing raises a profound challenge to the conventional wisdom about global warming predictions based on global circulation computer models. The paper by Roy W. Spencer and William D. Braswell of the University of Alabama at Huntsville shows that […]

The Tide Turns for Marine Energy Devices. Siemens Energy recently secured a 10% stake in Marine Current Turbines, the UK company that owns SeaGen, a 1.2-MW tidal power plant, which was commissioned in 2008 on the Irish Sea. Marine Current Turbines is planning to build a larger, 8-MW plant off the coast of Scotland by […]

Longview Power, a 695-MW coal-fired power plant now under construction in Maidsville, W.Va., is scheduled to begin commercial operation later this year. The $2 billion project reached 580 MW in early June, just a month after completing the “first fire on coal” schedule milestone. Testing and tuning of the controls and various systems continue.

Enwave Energy Corp.’s district heating plants in downtown Toronto will be operating cleaner and more efficiently before the fall 2011 heating season begins when boiler upgrades now under way are completed. Enwave hired Benz Air Engineering (BAE) to design and install upgrades to all eight boilers inside Enwave’s Pearl Street Station. When the $20 million project is completed, the retrofits will produce energy savings exceeding $5 million per year. In addition, the company will receive incentives of $100,000 per boiler from Enbridge, its natural gas provider.

Steel piping systems used to convey coarse materials, often over long distances, are under constant attack from abrasion. In power plants, the materials are usually coal and limestone slurry. The common industry solution has been to install abrasion resistant (AR) pipe that is much harder on the Brinnell Scale than standard steel pipe. The harder the inner wall, studies have shown, the better it resists the gouging or plowing action of abrasive sliding particle flow.

The regenerative air heater on a typical steam generator usually accounts for over 10% of a coal-fired plant’s thermal efficiency. A poorly performing air heater will cause an increase in the gas outlet temperature, often reducing the electrostatic precipitator collection efficiency and baghouse reliability. Recent design innovations enable restoration of this lost performance.

It is time for the renewable integration discussion to move beyond simply identifying the challenges of ensuring reliability in a nation increasingly served by intermittent renewable resources and toward developing real-world solutions to these challenges.
