High efficiency and large capacity to promote energy utilization. SPIC has a total installed capacity of 7145.69 MW from thermal power. Currently SPIC owns eight 1,000 MW class units, and forty-seven 600 MW class units, accounting for 56.89% of the total thermal power capacity, ranking the first among China’s top five generators.
Committed to clean development of thermal power. 100% of thermal power plants in operation are installed with De-SOx and De-NOx devices. Ultra-low emission rehabilitation projects are being carried out with the target of reaching or even exceeding the emission standards of gas-fired power plants.
Invested by SPIC subsidiary Shanghai Electric Power (SEP),Phases I and II of Tianji Power Plant successively won the Luban Prize, Classic Project of 35th Anniversary of China’s Reform and Opening Up and the Gold Award for National Quality Engineering. The project utilizes several energy-saving technologies with the reheat steam temperature 20 °C higher than that of standard ultra-supercritical (USC) units, effectively boosting energy-efficiency.
Invested by SPIC subsidiary China Power International Holding (CPIH), Pingwei Power Plant (Phase III) 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 at the same time. With a total capacity of 4,540 MW, it is the largest thermal power plant of SPIC.
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.
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, CO2 emission and loss of resources caused by coal transportation are sharply decreased.
Comprehensive utilization and conservation of water. SPIC establishes 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 m3 and 1.5 million m3 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 m2, 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.
Highly efficient utilization of clean energy by smart grid. With the goal of consuming all wind power, SPIC builds environment-friendly, economical, safe and reliable modernized smart grid, where peak load is regulated by thermal power plants along with the participation of aluminum load, while security and stability control, automatic dispatch, real-time monitoring and closedloop control system operate jointly. Up to date, wind power penetration rate in the smart grid has reached 38.25%, exceeding that of Denmark, which has the highest utilization ratio of renewable energy in the world.
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.
SPIC holds national Grade A qualifications for power plant construction, supervision, commissioning, engineering design and overseas EPC contracting. Besides, SPIC is also capable of providing engineering consultancy and bidding agency services, as well as supervision in equipment manufacturing, building construction engineering, port and navigation projects, mechanical and electrical installation and petrochemical projects. SPIC creates an EPC management model focusing on the design, establishes and optimizes a project manage system complying with international standard and combining with advanced management concepts for nuclear power. SPIC is the EPC contractor for more than 160 thermal power units with a total capacity of over 57,000 MW.
SPIC takes a leading position in the application of high-efficient coal-fired technologies in China, and holds the top-level design qualification in China, i.e. Class A Comprehensive Engineering Design Qualification, covering all types of generator units, all parameter levels and engineering conditions of thermal power generation. It possesses the capability of key technology research on 1,000 MW class ultra-supercritical units with high parameters as well as capabilities of planning and consulting, survey and design, technical modification and lifetime service. It also has top-ranking technologies and profound experience in operation optimization of power stations, energy saving and consumption reduction, and in boosting ecological environment protection level.
SPIC is the major designer of UHV grid in China and a primary technology supplier for State Grid Corporation of China with comprehensive design capabilities for power transmission and transformation in various areas such as highlands, plains and different voltages including UHV, EHV, HV and LV distribution projects. SPIC undertook the design of China’s first ±1,100 kV, 1,000 kV UHVAC and ±800 kV UHVDC transmission lines and multiple 750 kV EHVAC, ±600 kV EHVDC, 500 kV EHVAC lines. SPIC has designed a total of 22,000 km of 1,000 kV and lower voltage transmission lines.
