The wind power, photovoltaic power plant capacity coefficient changes with the seasons scenery can be 'complementary'

ShuYin puma: the current management situation of coal industry is very serious, percentage of loss-incurring enterprises for more than half, the main reason lies in the coal fuel costs is not effective. The cost of coal accounts for about 70% of coal, coal prices impact on power generation cost of enterprise management is self-evident. Although the coal enterprise and signed some long synergistic with coal production enterprises, but coal purchase price is largely affected by coal market price fluctuations. Thanks to the failure of a feed-in tariff and coal linkage, so coal enterprises face the lack of effective response to a sharp rise in fuel costs. This is the main difficulties of coal enterprise. In addition, also led to the decrease of the electricity price, electricity market dealing coal profit space was further compression.

solar photovoltaic webex: electricity generation capacity coefficient is will generate the total energy of a given time period divided by the factory during this time of the energy generated at runtime. In 2018, for example, the U. S. nuclear power unit ( 93%) And gas combined cycle generator ( 58%) High capacity coefficient, and wind power, 37%) And photovoltaic ( 26%) The capacity of the coefficient is relatively low.

in the nationwide, the wind power plant capacity coefficient tend to be highest in spring, the summer fell about 30%, and increased again in late autumn. In the spring of 2014 to 2019 in winter, wind power capacity coefficient of median: 38 in the spring. 2%, 26 in summer. Fall 4%, 33. 6%, 38 during the winter months. 1%.

because light time longer, the performance of the photovoltaic power station to peak in the summer, and the wind seasonal & other; Complementary & throughout; 。 Photovoltaic power station capacity coefficient of median: spring 27. 5%, 30 in summer. In the fall of 2%, 22. 6%, 16 during the winter months. 7%.
