Coal

After more than a decade debating whether to pass a carbon-limiting law, Australia’s Senate in November voted in a landmark bill that will impose a price on carbon emissions. The country, which accounts for just 1.5% of global carbon emissions, but which is the world’s highest emitter per capita because 80% of its power comes […]

Over the past 11 years, the Powder River Basin Coal Users’ Group (PRBCUG) has grown to become the voice of North American generating companies that are dedicated to the safe and efficient use of PRB coal. POWER, the group’s media sponsor, has reported on the PRBCUG’s annual meetings, which are colocated with the ELECTRIC POWER Conference & Exhibition each year. POWER also reports annually on the group’s coal plant of the year award. For 2011, in the large plant category the award went to Kansas City Power & Light’s Iatan Unit 2 (see our August 2011 issue); the small plant category winner, Muscatine Power & Water, is profiled in this issue, beginning on page 56.

U.S. optimism has been restored by reports of abundant, reasonably priced natural gas to fuel most new generation; however, huge gaps in the fuel delivery system (thousands of miles of pipelines are needed) will soon challenge gas plant development. Meanwhile, the cloud of sovereign debt hangs over all major capital projects in Europe, where the UK moves ahead with new nuclear projects while many of its neighbors shut the door on nuclear and struggle to finance their commitment to renewables.

The Five-Year Plan is the expression of the centralized planning goals for China’s economy. The 12th Five-Year Plan, approved by the Chinese Government on March 14, 2011, established many social and economic goals, including significant expansion of the country’s power generation industry in many new directions.

The EPA’s proposed rules on limiting greenhouse gas emissions from new, modified, and existing power plants has taken another step forward.

After three years of development, dozens of public workshops, and hundreds of meetings with stakeholders, the California Air Resources Board (ARB) on Oct. 20 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.

ICF International, a consultancy group that earlier this year had predicted 68 GW of coal-fired power plants could retire by 2030 as a result of finalized and proposed regulations from the Environmental Protection Agency (EPA), downgraded its retirement projections to 50 GW this fall.

Ditching the only project remaining in its £1 billion ($1.60 billion) carbon capture and storage (CCS) competition, the UK government declined to back the much-watched CCS project at the Longannet power station in Fife, Scotland, in October. The decision balances the UK’s low-carbon ambition with the need to ensure that taxpayer money is invested in “the most effective way,” the nation’s Department of Energy and Climate Change said. The funds are now expected be used to “pursue other projects” in both Scotland and England.

A Romanian lignite-fired power station wanted to minimize the operating cost of the flue gas desulfurization (FGD) system by placing the booster fans in the "wet position," between the wet FGD scrubber and the wet stack, where they would consume significantly less power. A number of combined environmental effects must be considered in this design.
