Purpose/aim The aim is to explore which price policy of the Chinese wind power is the most suitable for the market. Design/methodology/approach Data has been collected through questionnaires. The analysis includes the statistical test in form of chi-square. Additionally the whole thesis followed the onion process put forward by Saunders. Findings The analysis showed that the price policy which is based on the local price of coal is more suitable for the market than the price policy decided by concession projects. Originality/value An original idea is given the relationship between ages, education levels and two policies. Further, the empirical data is collected from a comprehensive online-forum, so that the samples are randomly selected. The data shows that the businesses which want to enter the Chinese wind power market should choose the price policy which is based on the local price of coal. This choice should be useful in the real life.

Sri Lanka is an island at the Indian Ocean with 65234 km2 and it has a power demand of 2000 MW. The hydro power was the main power source before year 2000, after maximum usage of hydro power Sri Lanka installed fossil fuel power plant to achieve the demand. Then the electricity price gradually increased due to higher increment of fuel price. As the solution for this higher price of electricity the government has to go to new profitable power source the coal power. Finally year 2011 Puttalam coal power plant 300 MW x 1 was installed with the hope of providing the low cost reliable energy supply to Sri Lanka and it will be extended to 300MW x 3 plan in year 2015. Therefore the puttalam coal power plant is the key power plant to the Sri Lankan power generation and it is expected to have the maximum output (base load) to the Power demand of Sri Lanka. Sri Lanka is a tropical country and it has two different weather seasons as rainy season and dry season. The puttalam power plant situated at Kalpitiya peninsula and it has normally dry weather condition, Months of April, October November and December have heavy rain condition (Meteorological Department, Sri Lanka, 2012). The puttalam coal power plant may not achieve full load because of high moisture content at rainy season. So this Thesis carried out to find the capability to achieve the full load with available plant, plant capacity by using different coal qualities. Then find the economical benefits and effect on the environment with the recommended coal for different seasons and also design a storage plan to coal storage at existing coal yard. Based on the historical data and the Meteorological department rain fall data and by doing a technical analysis the recommended coal type was selected and the capability of plant equipment capacity to the recommended coal to achieve the full load was analyzed. Then the coal storage plan was designed according to annual requirement of the different recommended coal and economical benefit was analyzed by considering last year cost for generated power and the generation cost, if recommended coal is used for last year. Finally flue gas analysis was carried out for the recommended coal to find the effect on the environment. The recommended coal for rainy season is with the heating value of 6600 kcal/kg and for dry season it is 6300 kcal/kg. The capacities of main boiler and other plant equipments are capable for the recommended coal to achieve the full load of the plant. Then the design of the coal storage plan was given under figure 4.2 and table 4.1. It was calculated that a profit of 3.932 million US$ can be achieved by using the recommended  coal for the last year and also when compared with the changing price of oil and coal it will be more profitable for the future. Because the oil price increases very rapidly and the increase in coal price is very low compared to the oil price. Finally the SOx and NOx emissions from recommended coal were analyzed and it was within the environmental limits because of the high quality emission reduction plant equipments.

This thesis investigates to what extent coal prices differed globally during the nineteenth and twentieth centuries, and whether those differences mattered for economic development. The backbone of my empirical investigation is a new dataset of annual coal prices spanning the years 1840 to 1960 for, on average, over 30 globally distributed ports. This dataset is complemented by pithead prices for all major coal-producing countries. My analysis includes all major steam coals and I eliminate quality differences by accounting for differences in their carbon content. I construct my argument by examining two major drivers of differences in coal prices. First, I examine trade costs for Welsh steam coals, which were shipped to most regions of the world. Secondly, I estimate the effect of the spread of coal mining, for example to India, on local coal prices by initating competition between coals from different origins. While trade costs declined most during the late nineteenth century, the spread of coal mining led to continued price convergence in the interwar period. And yet, global coal price differences remained significant, especially between producing and importing countries. Arguably, my most interesting finding is on the effect of those coal price differences. More specifically, I calculate the ratio of coal prices to wages, and explore whether countries where this ratio was closer to the British ratio were in the best position to use the most advanced steam technology. My econometric results indeed show that countries with a low coal price/wage ratio experienced higher manufacturing output growth during the period 1870 to 1940. This finding of my thesis highlights one potential way in which different levels of coal prices may have contributed to varying degrees of technology adoption between countries and ultimately economic growth.
