Its the delivered cost on your utility bill that counts; the capital cost of the plant itself is only a single component. Large, central power plants provide the reliability and flexibility utilities require for baseload, cycling, and on-demand situations. They can be strategically located near load centres or along transmission corridors and provide the economy of scale needed to minimize the cost of…...

...Bandi Mohit Sai Kumar MBA-IB, Sec: A 1226112109 The World's Greatest Coal Arbitrage: China's Coal Import Behavior and Implications for the Global Coal Market Summary China is home to the world’s second largest proven coal reserves after the United States. In addition, prior to 2009, China was a net coal exporter. Coal is a cornerstone of the Chinese economy, representing 77 percent of China’s primary energy production and fueling almost 80 percent of its electricity. Moreover, China is the world’s top coal consumer, accounting for nearly half of global consumption in 2010. Over the past decade, China’s domestic coal output has more than doubled while its coal imports have increased by a factor of 60—the country’s dependence on other nations’ coal exports is growing. In 2009, the global coal market witnessed a dramatic realignment as China burst onto the scene, importing coal from as far away as Colombia and the United States. With 182 million tons (Mt) of coal sourced from overseas suppliers in 2011, China has overtaken Japan as the world’s top coal importer. Moreover, as the world’s top coal consumer, China’s imports could rise significantly again by 2015. China’s recent move from being a net coal exporter to a net coal importer portends significant changes on the global stage, especially in terms of climate change. Understanding China’s rising coal imports is crucial for managing their global impact. Introduction In 2009 the global coal market witnessed one of...

... reason, coal-fired boilers are required to have control devices to reduce the amount of emissions that are released. Water Resource Use Large quantities of water are frequently needed to remove impurities from coal at the mine. In addition, coal-fired power plants use large quantities of water for producing steam and for cooling. When coal-fired power plants remove water from a lake or river, fish and other aquatic life can be affected, as well as animals and people who depend on these aquatic resources. Water Discharges Pollutants build up in the water used in the power plant boiler and cooling system. If the water used in the power plant is discharged to a lake or river, the pollutants in the water can harm fish and plants. Further, if rain falls on coal stored in piles outside the power plant, the water that runs off these piles can flush heavy metals from the coal, such as arsenic and lead, into nearby bodies of water. Coal mining can also contaminate bodies of water with heavy metals when the water used to clean the coal is discharged back into the environment. This discharge usually requires a permit and is monitored. How electricity is generated through coal First the coal is ground to a fine powder and put into the boiler, where it is burned, converting its chemical energy into heat energy. Grinding the coal into powder increases its surface area, which helps it to burn faster and hotter, producing as much heat and as little waste as possible. As well as heat...

Also, another issue was that the IT did not meet with the management team to discuss what drives the employees should have access to. All employees should not have access to the finance drive and payroll. “Quality control focuses on monitoring the activities and results of the project to ensure that the project complies with the quality standards. Once the project’s standards are in place, it is important to monitor them to ensure that the project quality objective is achieved.” (Marchewka p.343) During the PC Swap there should have been better quality control. Because there was no procedure in place, there were issues with this project. “Pareto diagrams are useful for identifying and investigating the most significant problems in ranking problems in descending order from left to," (Marchewka p327) The IT department could have use the Pareto diagram.

Quality Control and Tqm

... certification, this norm must be seen as a way towards TQM. A minor group of researchers has compared the joint effects of TQM and ISO 9000 and they agree in pointing out that TQM implementation leads to better results in more aspects than ISO 9000 certification (Terziovski et al., 1997). However, one of the benefits attributable to the standard is that it constitutes a good first step towards a TQM system, raising awareness on quality amongst workers and creating a good climate to implement it (Taylor, 1995; Tummala and Tang, 1996; Baena López, 1998; Skrabec, 1999; Sun, 2000; Escanciano et al. , 2001). There is even another group of researchers that affirm that the ISO 9000 certification has more impact on company performance when it is implemented with the objective of continuing and finally implementing a TQM system (Brecka, 1994; Meegan and Ta ylor, 1997; Huarng et al., 1999; Hughes et al., 2000; Sun, 2000; Gotzamani and Tsiotras, 2002). It is important to point out that the literature shows that the TQM dimensions that best influence companies’ results (the soft variables) are those that have a lesser weight in ISO 9000. Moreover, the points of TQM with more importance for ISO 9000 (basically process control) do not have a significant positive effect on company results. After having classified and revised the literature regarding TQM/ISO 9000 in company performance the following hypotheses regarding the effect of TQM and ISO 9000 have been tested...

... believe that effective regulation in these sectors will attract foreign investors as well as encourage export of locally produced foods, cosmetics and pharmaceutical products. Regulation is a public policy that controls private behavior for public good. Effective regulation assures the quality and safety of our regulated products and also stimulates growth in the industry. Under regulation often results in low quality products that cannot compete favorably in the market while over regulation results in stifling of enterprises and investments. NAFDAC regulatory activities strive to strike a balance so that quality is maintained while investments are protected and promoted. Effective regulation is one of the keys to strengthening and unlocking Nigeria’s latent development potentials in the food and pharmaceutical industry as well as other sectors of the economy. It was in a bid to strengthen the local industry, position it for growth and development as well as encourage foreign investment that NAFDAC was established with the mandate to regulate the products and activities of the industries.
