Tianjin Energy Investment Group Co., Ltd. was established on May 30, 2013. With approval, it was reorganized by Tianjin Jinneng Investment Company and Tianjin Gas Group Co., Ltd. It is a wholly state-owned company invested and supervised by the Tianjin State-owned Assets Supervision and Administration Commission with a registered capital of 10.045 billion yuan. As the main body of investment, construction and operation management of Tianjin's energy projects, the group takes "four sources", namely power supply, gas source, heat source and new energy as its main business, and undertakes the important task of ensuring the safe and stable supply of Tianjin's energy and promoting the adjustment and optimization of the city's energy structure.

In the field of power generation, Holdings has built the largest gas thermal power plant in China - Tianjin Chengnan Gas Thermal Power Plant. It has cooperated with large power generation companies to invest in the construction of Tianjin's main power generation project, and the Nanjiang Thermal Power Plant is under construction. As of the end of 2016, the group had invested in the construction of a total installed capacity of 11.793 million kilowatts, accounting for more than 80% of Tianjin's adjustable installed capacity.

In the field of gas supply, a gas industry chain has been formed that integrates planning and design, gas source development, engineering construction, pipeline transmission and distribution, sales and supply, with 3.49 million gas users, accounting for 92% of the city. The gas supply pipeline network is 14,455 kilometers, covering 16 districts in the city. The gas supply in 2016 was 4.225 billion cubic meters, accounting for 70% of the city's total natural gas supply. Gas transmission and distribution projects such as Dagang Gas, northern Shaanxi Gas, Boxi Gas, North China Gas, and Lingang LNG have been built, and projects such as 4 billion cubic meters of coal-to-natural gas in Keshketeng Banner, Inner Mongolia, Datang.

In the field of centralized heating, we actively promote and improve the construction of a "one network" for heating supply in the city, create a networked and peak-shaving heating system with cogeneration of heat and power and gas heating as the main body, and vigorously promote the development of clean heating. We have formed a relatively complete industrial chain covering the production and supply of heat sources, heating project planning, design, construction, supervision and cost consultation, heating insulation pipelines, heat exchange equipment manufacturing and system integration, as well as heating production operation and management. Several large-scale cogeneration heating networks have been built, and the Nanjiang Heat Network is under construction, with a centralized heating capacity of 147 million square meters. The actual heating area in 2016 was 107 million square meters. It undertakes the heating tasks of 750,000 residents, government agencies, enterprises and institutions in the city, and achieves 100% clean heating.

In the field of new energy, we actively promote the development and application of solar power generation, wind power generation and geothermal energy. The Dashentang wind power project has achieved a breakthrough in Tianjin's zero wind power generation. Tianjin West Railway Station Photovoltaic Power Station, as a large domestic amorphous silicon roof photovoltaic building integration demonstration project, has been successfully connected to the grid to generate power.

The group actively promotes the integration of industry and finance, and owns Jinran Utilities Co., Ltd., a company listed on the main board of Hong Kong; it is the second largest shareholder of Datang International Power Generation A-shares and the third largest shareholder of H-shares; it participates in financial businesses such as Bohai Securities, Bohai Industrial Investment Fund, and TEDA International. We have established a solid bank-enterprise cooperation relationship with financial enterprises and institutions, providing strong financial support for the development of main business and project construction.
