TECO has been deeply involved in the energy industry for many years. In recent years, it has expanded the intellectualized system construction for energy harvesting, energy storage and energy and has focused on three core green energy businesses which include solar energy, energy storage and offshore wind power. In addition to energy industry, we also oriented to various scopes with intellectualization as core; such as modulized Internet Data Center (IDC) and providing various solutions for smart communities through system integration, to become provider of solutions for intellectualization and system integration from traditional equipment manufacturer. As we built the Hukou factory as green energy demonstration factory, we have integrated construction team and product equipment resources to optimize product efficiency and strive to promote clean energy and sustainable social development.
