Little Bay Power Station in Yunnan, \
During the flood season (June-October) and dry season power (11 May) the proportion of electricity from the free time of 62.0:38.0 Xiaowan improve 52.4:47.65 ensure total annual power consumption the proportion of the time by the non-Xiaowan 46.4% to 85.6%. Joint optimization of inter-basin through the system operation, the operation Xiaowan Yunnan Electric Power System will improve the regulation performance of hydropower stations, with years and years to adjust the capacity of hydropower hydropower capacity of the province by the total volume of the pre-production won WaterPowerVo1 .30. No. 1012.5% or so increase to 68.5%, and hydropower stations flood, dry season the proportion of electricity generation by the non-Xiaowan improve 49.6:50.4 64.3:35.7 time to ensure that electricity accounts for proportion of electricity when no Xiaowan 52.8% to 86.0%,[link widoczny dla zalogowanych], will reverse the long-standing existence of Yunnan Electric Power System \As the regulating role of Little Bay Reservoir, Yunnan Power Grid systems can enhance the peaking capacity utilization rate during the non-Xiaowan 88.5% to 98.7%, which brought huge economic benefits for the system. The system power consumption balance calculation, the small Hydropower Station in Yunnan can also make the system effective net charge of about 6.2 billion kW · h. With the social and economic development, industrial structure adjustment and improvement of living standards, \h, the average growth rate of 7.5%; \Expanding west to east and flexible marketing strategy phased power,[link widoczny dla zalogowanych], and further to effectively stimulate the Yunnan Electric Power Market, driving the rapid growth of electricity demand across the province. 2001 the province's electricity consumption was 34.53 billion kW · h, an increase of 9.2%. 2002 reached 38.99 billion kW · h, the growth rate up to 12.9%. Load forecasting based on the results of Yunnan Province: 2010,2015 electricity demand in the whole society in Yunnan Province were 72.5 billion, 100.8 billion kW · h; 2010,2015 Yunnan Province in the highest power load of the whole society will reach l250 million, l744 million kW. 3 has significant economic and social benefits both Little Bay hydropower station in Yunnan Province, \The mechanical and electrical construction industry can lead the province, building materials industry, transport and the development of tertiary industry, to achieve expansion of domestic demand and stimulate economic growth, the goal to provide more employment opportunities, thereby stimulating economic development in Yunnan Province,[link widoczny dla zalogowanych], to accelerate poverty reduction in border areas rich. It is estimated that about 30% to 40%, or consumption of 100 billion investment project in the province. Little Bay Power Station is completed, the whole community to create an annual economic benefit of about l000 million, to accelerate the training of Yunnan hydropower-based electricity to the pillar industries and to promote the development of superior resources,[link widoczny dla zalogowanych], the Yunnan province by the resource becomes strong economy, a very important role in promoting. Hydropower is renewable, clean energy and Little Bay Power Station was completed in a year to replace coal-fired thermal power capacity of about 25.24 billion kW-h, saving coal equivalent of about 86o million t, which can reduce the number of SO, CO and other emissions, and waste water and waste emissions and improve the environmental quality of human life. The environmental benefits are substantial. Little Bay Reservoir dam storing more than the average annual suspended load and bed load sediment l50 million,[link widoczny dla zalogowanych], 48 million t and t, so that has been built downstream Manwan and Dachaoshan Hydropower Station, over machines to reduce the volume of sand, thereby reducing the turbine wear and tear, so to maintain a high efficiency turbine operation; but can also extend the useful life of reservoirs; also allows the Jinghong Hydropower Station in Nuozhadu building of the reservoir water level before the operation to improve the flood season, thereby increasing the generating capacity of nearly 500 million kW · h. Little Bay Reservoir can be combined to provide flood storage capacity Hennessy l3.18 million in, storing more than Jinghong dam nearly 50% of the sediment, thereby reducing sediment deposition Simao Port; also cut 12% of the peak, thereby enhancing the downstream Manwan, Dachaoshan Hydropower flood protection standards; reduce hydropower stations downstream Nuozhadu reservoir backwater reservoir and construction of temporary diversion flood losses and other expenses. Little Bay Power Station which is not currently navigable river, the reservoir can be formed after the completion of main river area of deep water channel 178km, black-Hui Jiang Reservoir tributaries deep channel 123km, to create the conditions for the development of shipping the reservoir area; by Little Bay reservoir regulation, the Lancang River increase dry season river flow downstream shipping conditions will be improved significantly.
