GMIE is operating 11.72 GWs of coal-fired power plants, 40% of which are circulating fluidized bed generators. With more than 20 years of operation and management experience in low-calorific coal-fired power generation, the Group gives priority to developing low-calorific coal-fired power plants to promote energy conservation, emission reduction and environmental protection. In addition, GMIE is committed to strengthening the deep integration of energy industry and modern information technology, continuously promoting the construction of "Internet+" intelligent energy, speeding up the pace of "smart power plants", improving quality and efficiency, and achieving clean and efficient use of coal. It actively expands the power transmission market and turns resource advantage into economic advantage. At present, the Group accounts for 46% of the power transmission capacity outside the province.

To answer the call of the country to develop clean energy, GMIE focus on the strategic objectives of "carbon peak, carbon neutrality", and keep increase the weight of clean energy business. At present, the operation of new energy projects in GMIE has reached 880MWs, increasing 2.4 times in three years and has gradually become the new development engine of the Group. GMIE will continue to actively lay out the development of “integration of wind power, solar photovoltaic, hydro power, thermal power and energy storage” as well as "Integration of power supply, power grid, load and energy storage" promotes leapfrog development of clean energy and builds a modern energy system.

GMIE operates sewage treatment plants in more than 10 cities throughout the province with waste water treatment capacity of 343 thousand tons per day and regenerated water recycling capacity of 210 thousand tons per day. Based on municipal sewage treatment and reclaimed water reuse, the Group actively carries out sludge treatment equipment manufacturing and sales, environmental engineering, water treatment technology application and other related businesses to improve the utilization of renewable resources and promote the development of social circular economy.

GMIE has scientific research platforms such as Shanxi Provincial Clean Combustion Project Center for Circulating Fluidized Boiler Bed Units, which are jointly built by the local and central governments, Shanxi Technical Center for Coal Gangue Power Generation Industry, and US-China Energy Center (Shanxi). They have successively carried out key scientific research projects such as classified utilization of low caloric value coal, combined supply of electric, heat and gas, ultra-high temperature gasification and melting, in addition, comprehensive utilization of fly ash. The Group also carries out in-depth Industry University Research Cooperation with colleges and universities as well as research institutions at home and abroad, jointly exploring technologies such as clean and efficient utilization of carbon-based resources, renewable energy, energy storage, etc., to help realizing the historic mission of transformation of Shanxi province.

GMIE promotes comprehensive energy supply services for thermal power, strengthens the co-supply of hot and cold hydropower and gas, and realizes the transformation from single energy supply to comprehensive service. It actively expands the environmental protection industry, explores and provides comprehensive recycling and treatment services for wastewater, waste gas and solid waste, and integrates the company development from single product to product and service. It strengthens the management of coal mine safety in production, reduces costs and increases efficiency, as well as improves operating efficiency. At the same time, the Group supports development of agricultural industry, consolidates the achievements of poverty alleviation, and helps the rural revitalization.
