Energy-saving demonstration project: Tianji Power Plant

Invested by SPIC subsidiary Shanghai Electric Power (SEP), Phase I (2 × 660 MW) of Tianji Ultra-supercritical (USC) Power Plant in Anhui Province won the Luban Prize in 2008 and was listed in 2014 as one of the 100 classic projects during the past 35 years since the reform and opening up policy was implemented.

Phase II (2 × 660 MW) of Tianji USC Power Plant won the Gold Award for National Quality Engineering in 2015. The project has adopted several energy-saving technologies with reheat steam temperature 20 °C higher than standard USC power plants. Unit 3 was awarded as the Most Optimal Coal Consumption Unit by State-owned Assets Supervision and Administration Commission (SASAC) in 2015 with a lowest net coal consumption of 274 g/kWh, 10 g/kWh lower than the average level of plants of the same type in China, which leads to a reduction of 62,700 tons of standard coal consumption, 166,800 tons of CO 2 emission and 1,300 tons of SO 2 emission each year.

 
 
“Triple-thousand engineering” demonstration project:Pingwei Power Plant

Invested by SPIC subsidiary China Power International Holding (CPIH), Pingwei Power Plant is the world’s first project with 1,000 MW capacity per unit, 1,000 kV main transformer and 1,000 kV ultra-high voltage (UHV) transmission line. With a total capacity of 4,540 MW, it is the largest thermal power plant of SPIC.

 
 
Clean emission demonstration project: Caojing Power Plant

Caojing Power Plant of SEP is SPIC’s first thermal power plant with 1,000 MW units. It won the Gold Award for National Quality Engineering in 2011 and was listed as one of the classic projects during the past 30 years since the award was established. The clean emission project of Unit 2, identified by the National Energy Administration (NEA) as one of the 13 demonstration projects for environmental protection rehabilitation on coal-fired units, was put into operation in February 2015. After the renovation, the emissions of flue gas, SO 2 and NOx have reached 1.8 mg/m 3 , 13.9 mg/m 3 and 21.6 mg/m 3 respectively, which were superior to those of gas-fired units.

 
 
Representative project of circular economy:Huolinhe National Demonstration Industrial Cluster

Huolinhe Circular Economy Demonstration Project is listed as a national demonstration project. It takes efficient and circular utilization of resources as the core, “reduction of quantity, re-utilization and recycle” as the principle, and sets up the circular economy industrial cluster of coal, power, heat, aluminum, railway and port.

Classification of coal use. Low-grade coal is consumed on site to generate electricity for aluminum smelting; medium-grade coal is supplied to mine-mouth power plants, replacing coal transport with power transmission; high-grade coal is transported to fuel power plants near ports or railways. In this way, CO 2 emission and loss of resources caused by coal transportation are sharply decreased.

Comprehensive utilization and conservation of water. Establish the three-level complementary way of water consumption:massive utilization of urban reclaimed water as the core consumption, maximum utilization of coal mine drainage as auxiliary consumption and minimum utilization of surface water as backup consumption, so as to reduce water consumption and protect the environment. The usage of urban reclaimed water and coal mine drainage is 3.65 million m 3 and 1.5 million m 3 per annum respectively.

Cogeneration. Thermal power plants generate electricity for aluminum smelting by consuming the low-grade coal while cogenerating, supplying and selling heat and power. With a heating area of 4.5 million m 2 , cogeneration plants have replaced more than 40 inefficient coal-fired small boilers supplying heat to residents in the Huolinhe region, preventing air pollution caused by the boilers.

Storing energy in aluminum. Aluminum smelting transforms low-grade coal on site into energy that is effectively stored.The 810,000 t/y aluminum smelting capacity can store the energy of 10 million tons of lignite and 1 TWh of wind power into aluminum products.

Joint operation of coal, power, railways and ports. SPIC realized the joint operation of coal, power, railways and ports through eastern Inner Mongolia’s Tongliao–Huolinhe Railway, Chifeng–Daban–Baiyinhua Railway, Jinzhou–Chifeng Railway and auxiliary ports. Coal mining, transport and sales have been integrated and equilibrium has been achieved in both directions. The great passage for exporting the coal from eastern Inner Mongolia has been established with the flows of logistics, information and funds synchronized.
