Trung Quốc trúng thầu $1.3 tỷ nhà máy điện Trà Vinh
Bị cáo buộc ‘kém năng lực’ và ‘chậm trễ’ nhưng vẫn trúng thầu: Nhà cầm quyền Hà Nội vừa cho một tổ hợp công ty của Trung Quốc trúng thầu xây dựng một nhà máy nhiệt điện chạy than ở tỉnh Trà Vinh với tổng vốn đầu tư lên khoảng 1.3 tỉ USD.
Theo bản tin hăng Reuters hôm Thứ Sáu, Tập đoàn Điện Lực Việt Nam (EVN) đă chọn một tổ hợp của Trung Quốc để thực hiện dự án nhiệt điện Duyên Hải 3 đặt tại tỉnh Trà Vinh.
Chinese firms get $1.3 bln power plant deal in Vietnam
Fri Aug 5, 2011
State utility Vietnam Electricity (EVN) group has awarded a $1.3 billion contract to a consortium of Chinese companies to build a coal-fired power plant in Vietnam's southern region, the official Vietnam News Agency reported on Friday.
EVN signed the engineering, procurement and construction contract with the Chengda-Dec-Swepdi-Zepc consortium on Friday to build the 1,245 megawatt Duyen Hai 3 thermal power plant in Tra Vinh province, 250 km (155 miles) south of Ho Chi Minh City, the report said.
Chinese banks will provide loans worth 85 percent of the plant's investment, and the remaining 15 percent will come from EVN's funds, the report said without giving specific details on Chinese companies and banks involved.
The plant with two generators will start operation in the third quarter of 2015, using 3.5 million tonnes of anthracite coal annually from the northern province of Quang Ninh, Vietnam's coal hub, to generate 7.5-8 billion kilowatt hours of electricity per year.
Duyen Hai 3 plant is part of the Duyen Hai coal-fired power complex, which has a total capacity of 4,200 megawatt. EVN began construction of the $1.5-billion, 1,245-megawatt Duyen Hai 1 plant last September.
Coal will take over from hydro power as the leading fuel for new generators in Vietnam in the next five years, EVN has said.
A power master plan projected that thermal plants in Vietnam will need 67.3 million tonnes of coal a year by 2020, when the fossil fuel may account for almost half its power mix.
In a separate development, Japan's Marubeni Corp said on Friday it had agreed in principle to sell up to 2 million tonnes of Australian or Indonesian coal a year to Vinacomin, Vietnam's top coal mining group, and hopes shipments can start in 2015-16.

CCCEH Research in China
Begun with support from the V. Kann Rasmussen Foundation, the Center conducted a prospective molecular epidemiology study from 2001-2008 to determine the risks to children’s health from air pollution generated by burning coal and other fossil fuels. The study site was located in Tongliang County, Chongqing, China, where a coal-fired power plant was located in the center of town. Until recently, the Tongliang Power Plant was the only major source of air pollution in this urban area. It consumed more than 20,000 tons of coal per year and was not equipped with pollution reduction technology. The power plant was scheduled to be closed in 2004, making Tongliang an ideal site to study the health effects of energy-related air pollution because these effects could be studied before and after the shut down. The aim of the study was to determine the health benefits to newborns of reducing in utero exposure to toxic air pollutants generated by coal burning.
This was the first molecular epidemiologic research study in China to examine the effect of exposure during pregnancy to air pollutants from coal burning, and document the health benefits to babies and children of reducing fossil-fuel related air pollution. Data from the study in China have also been analyzed with results from parallel studies in the United States and Poland, allowing for international comparison and confirmation of findings regarding children’s health and air pollution. Information about health risks to children, as a sensitive population, is urgently needed to make sound decisions about energy use and health policy in China and worldwide.
Background
Like many rapidly developing countries, China has relied heavily on coal-burning for low-cost energy production. Coal-burning accounts for 70 percent of total energy production and releases large amounts of PAHs (polycyclic aromatic hydrocarbons), particulate matter, sulfur dioxide, and mercury. Coal burning power plants are also a major source of carbon dioxide, the most important global warming gas. Coal-fired power plants in China currently produce 75 percent of the country’s electricity and the majority of new plants are being built to burn coal.
Study Methods — CCCEH scientists documented exposure, biomarkers, and health outcomes in three groups of babies and children whose mothers were enrolled into the study during pregnancy. One group of pregnant women, or “cohort,” was enrolled before the Tongliang power plant in the center of the city was shut down. The other two cohorts were enrolled after the the plant was shut down by the local government. Our study compares the health of children born to mothers who were exposed to high levels of air pollution during pregnancy when the plant was active, and mothers exposed to much lower levels of air pollution during pregnancy after the plant closed. Between birth and 5 years of age, children’s exposure to pollutants was measured repeatedly with air and biological samples, and children’s health is monitored biannually. Data collection in the study has ended, but data analysis continues.
Research Findings
Research results to date are demonstrating a critical health need for cleaner energy solutions.
* Newborns with high levels of prenatal exposure to air pollution from coal burning have smaller head circumference at birth. Such early exposures can set the stage before a baby is even born for increased cancer risk, and cognitive development delays, the effects of which can play out over an entire lifetime (Tang et al, 2006).
* Newborns in the first cohort (those who were in utero during operation of the coal burning power plant) had higher levels of DNA damage due to prenatal exposure to PAHs than newborns in either New York City or Krakow, Poland (Tang et al, 2006).
* Head circumference size was significantly improved among the 2005 cohort, born after the power plant shutdown, compared to the 2002 cohort (Tang et al, in prep).
* Children with the highest estimated exposure to PAH from power plant emission had significantly worse performance on neurodevelopment tests at age two years (Perera et al, 2008).
* Our monitoring and biomarker analyses show significant reductions in air contaminants of concern (PAHs, mercury) since the plant shutdown in December 2004. Air monitoring collected as part of the CCCEH project prior to final plant shutdown showed that ambient concentrations of benzo[a]pyrene in Tongliang were reduced by about 20% after the power plant closed. (Tang et al, in prep).
* CCCEH investigators and NRDC have co-authored an article in the Woodrow Wilson China Journal (China Environment Series 2007, Woodrow Wilson International Center for Scholars).
These results demonstrate a critical health need for cleaner energy solutions. Our study results are informing policy initiatives worldwide that are substituting cleaner energy alternatives for fossil fuels in order to better sustain natural resources, slow global warming, and improve human health.
