Why is Longpan Hydropower Station delayed?

The Hutiaoxia Hydropower Station, which first attracted serious media attention, was abandoned by relevant parties, but soon after the media was immersed in cheers, the dismounted project "appeared in BLACKPINK" under the new economic situation. In order to avoid public doubts, they renamed "Hutiaoxia Hydropower Station" as "Longpan Hydropower Station". The content of the project has changed, and the exploration tunnel and "three links and one leveling" (electricity supply, access, water supply and land leveling) projects are currently under way. If the dam site in the reservoir area is selected in Longpan, 654.38+10,000 people in the upper reaches of Jinsha River will be forced to emigrate, resulting in the inundation of 200,000 mu of cultivated land. This huge hydropower project with a static investment of 40 billion yuan directly impacted the red line of 65.438+0.8 billion mu of cultivated land set by the central government. We are very concerned about how to evaluate the impact of hydropower projects on the environment.

Regarding the site selection of the leading reservoir in the middle reaches of Jinsha River, many schemes have been compared and selected.

In Hutiaoxia reach, the first is the comparison of eight dam sites.

Wang Qiguo, the Yangtze River Geotechnical Engineering Corporation of the Yangtze River Water Resources Commission, wrote that according to the current level of dam construction technology in the world, dams should only be located on the overburden, and the minimum dam height of eight dam sites is 250 meters. The technical requirements for building high earth-rock dams have reached or even exceeded the world's leading level, and it is difficult to build dams.

Why did the reservoir choose here?

There have been two schemes for the normal water level in Longpan, namely, 20 12m and 1950m. There are no obvious restrictions. It should be determined according to the comprehensive analysis of the energy benefit of cascade compensation regulation, reservoir flooding loss, upstream connection, technical and economic conditions of the project itself, engineering quantity and investment.

When the normal storage level of Longpan is 1.950m, the total storage capacity is1795 million cubic meters and the storage capacity coefficient is 0.3 1. When the water level is 2012m, the total inventory is 37.4 billion cubic meters, the storage capacity is 28.4 billion cubic meters, and the storage capacity coefficient is 0.64. Can be adjusted for many years. Head from Longpan to Yibin1500m. Gezhouba will reach 1.700 meters, and the high dam scheme will reach 28.4 billion cubic meters. The storage capacity is equal to 65,438+0,000-65,438+0,654,38+0,000 billion kWh of stored energy.

Longpan, as a "leading reservoir", has a great compensation and regulation effect on downstream cascade hydropower stations. When the normal storage level of Shanglongpan is 20 12m, the downstream cascade power stations (excluding Shanglongpan Power Station itself, including the middle and lower reaches of Jinsha River (1 1), Three Gorges, Gezhouba, Yalong River Estuary, Jinping I, II, Guandi and Ertan Power Stations) will guarantee 46.04 million kilowatts. If there is no Longpan Reservoir upstream, the combined operation of downstream cascade hydropower stations can ensure an output of about 32.25 million kilowatts, with an annual power generation of about 465.438+052 billion kWh. Compared with the two, the guaranteed output increased by 65.438+03.79 million kilowatts, and the electricity consumption increased by 34.6 billion kWh. Among them, the Jinsha River cascade increased the guaranteed output by 6.5438+0.045 million kilowatts, and the electricity consumption increased by 32 billion kilowatts. When the Three Gorges Project increased the output of 2.86 million kilowatts and the electricity consumption of 23.5 billion kilowatts, the benefits were very remarkable.

Summary: Earthquake risk can be avoided by seismic design, and the state now stipulates that the first-degree fortification should be raised. If the earthquake intensity is 8 degrees or 7 degrees, the standard of one-degree fortification should be increased. After the Wenchuan earthquake, the hydropower industry adopted stricter standards than other industries.

Legal basis: the legal basis of environmental protection law;

Article 59 If an enterprise, institution or other producer or operator illegally discharges pollutants and is fined and ordered to make corrections, and refuses to make corrections, the administrative organ that has made the punishment decision according to law may impose continuous penalties on a daily basis according to the original fine amount from the day following the order to make corrections.

The fines and penalties specified in the preceding paragraph shall be implemented in accordance with the provisions of relevant laws and regulations, and determined according to the operating expenses of pollution prevention and control facilities, direct losses or illegal gains caused by illegal acts and other factors.
