Light and heat industry in Qinghai is booming

Light and heat industry in Qinghai is booming

The Qinghai region is endowed with unique conditions for the development of solar photovoltaic power generation industry. The annual average sunshine hours is over 3,000 hours. Solar radiation and sunshine are second only to Tibet in the country. It is an ideal place for building solar power stations. In 2013, the National Energy Administration organized a workshop on solar thermal power generation site selection and technical guidelines in Xining City, Qinghai Province, and completed the development of solar thermal power stations in Haixi, Haibei, Hainan, Yushu, Guoluo and Huangnan of Qinghai Province. Census and site selection for the site. Finally, in the six states, the light and heat site is 148 square kilometers, and 2960MW of exploitable capacity. In recent years, Qinghai Province has firmly grasped the major opportunity for the country to implement the new energy strategy, vigorously developed new energy represented by photovoltaics and solar thermal power generation, and continuously and vigorously promoted the advancement of the country's new energy industry.

Solar thermal power generation generates steam by generating steam from a steam turbine, which is the same as conventional thermal power generation. Therefore, it can be used in conjunction with various power sources such as photovoltaic power generation, wind power generation, hydropower, and pumped storage, without adversely affecting the power grid. At the same time, it can also provide reactive power, which is a friendly power generation method of the existing power system. Photo-thermal power generation is a solar power generation technology that can achieve stable and continuous power generation for 24 hours, and can replace thermal power to become the basic load of the power grid. During the five years from 2008 to 2013, the average annual growth rate of global installed capacity of CSP power generation is maintained at around 50%. In a predictable time, China's CSP market will exceed 20 trillion yuan in size, while molten salt materials and storage The thermal system-based energy storage technology will be the core competitiveness of CSP for stable power generation. The investment in energy storage systems is about one third of the total investment for CSP plants.

The scale of CSP has rapidly expanded in recent years, but the biggest bottleneck for CSP is the high cost. Compared with the photovoltaic industry, CSP energy storage devices can achieve continuous and stable power generation. At the same time, the requirements of the light and heat industry for equipment have driven the transformation and upgrading of many industries such as thermal insulation and mining. Therefore, various investment companies are actively preparing for the construction of a CSP demonstration project with independent intellectual property rights.

From the perspective of unclear policies, high prices of photovoltaic modules, and the development of the photovoltaic industry, the CSP generation will be a trend in recent years. Beijing Ji Peng Information Consulting Co., Ltd. undertook the preparation of the “13th Five-Year Plan” new energy development plan in Qinghai Province, involving the overall arrangement and coordinated development of the light and heat projects during the “Thirteenth Five-Year Plan” period, and is now in the stage of project statistics and recapture. We welcome the input of the people with lofty ideals in the preparation of the planning report and contribute to the development of light and heat in Qinghai Province.

LED Spot Light is a led light fixtures, mostly to project a specific project, and low voltage outdoor application. LED spotlighs is different from the LED Flood Light which is smaller can be install in a narrow place. And the 3W Led Spot Light, 6W LED Spot Light is widely use for building and garden lighting decoration.
