OREANDA-NEWS. December 29, 2011. China ENFI Engineering Corp. (ENFI) announced that, ENFI Ningxia Zhongwei Tianjingshan 30MW Photovoltaic Power Works, which was under full-process planning, investment, construction and operation by ENFI, was successfully combined to the grid and put into commissioning on December 22, 2011.

As a tracking solar photovoltaic power station with the maximum installed capacity at the present in the whole world, it is fully equipped with the intelligent linkage tracking system which is independently developed by ENFI. This system is featured by accurate solar tracking device and stable power generation indicators, which will greatly enhance the volume and quality of photovoltaic power generation and will be easily combined to the grid and operated. Comparing with the traditional solar photovoltaic power station, it will contribute an increase of about 25% in power output and the annual average generated energy will be up to 54 million KWH. On this ground, a total increase of 270 million KWH during the 25-year operation period.

This project is contracted by ENFI on an EPC basis. The construction works under the first phase (10MW) was formally commenced in March 2011 and completed in August in this year; the second phase (20MW) was started in October 2011, and completion acceptance as fulfilled in November 2011, marking a new record in terms of the construction speed of solar photovoltaic power station. In addition, the commissioning and grid connection works for the 30MW solar photovoltaic power station was successfully finished at one go-off, enabling the facility to generate benefit in the same year of construction. Taking advantage of technical R&D, fine design and scientific management, ENFI has stepped onto a new level in terms of the scientific technology and the power generation efficiency in this industry. As a matter of fact, a saving of 20% was realized on the investment costs and a satisfactory EPC benefit was eventually achieved.

Under this project, solar energy is utilized for power generation in a zero-emission manner, which will reduce the same volume of conventional thermal power supplied for the national grid, thus the annual average emission deduction of carbon dioxide will be 51,500 tons, and a total reduction of 1.3 million tons will be realized during the 25-year operational period. Comparing with the traditional thermal power works, the implementation of this project will bring about more favorable results such as: (i) coal saving for coal-fired power station; (ii) reduction of greenhouse gas emission; (iii) increasing of power supply and CDM (Clean Development Mechanism) achievements; and (iv) bringing about perfect economic benefits and long-lasting environmental benefits.
