In 2002, Greentec accomplished the first reaching standard comprehensive noise control project of coal-fire power plant boundary in China. In 2006, Greentec became the forerunner of the noise treatment of gas-fired power plant of our country by accomplishing the “Zhejiang Banshan Power Plant EPC Project”. In 2007, Greentec performed technology innovation again, and undertook the acoustic design and match EPC project of Tai Yang Gong In city thermal power plant and Zheng Chang Zhuang In city thermal power plant. In these projects, The grade A level has been achieved both on the plant boundary and on the sensitive point, and refreshed the record of the industry. Greentec has become the most preferred partner of the China five main electricity power groups in the field of noise and vibration control of power plant.

The noise control project of Beijing Guohua thermal power plant was accomplished in 2002, which was the first reaching standard noise control project in thermal power plant of China. After the accomplished of project, Beijing Guohua reach the grade B level of National factory boundary noise standard, and 3 years after the standard reaching, Beijing Guohua was evaluated as the national environmental friendly enterprise.
