Since the implementation of the dual carbon target, high energy consuming traditional coal chemical industry has always stood at the crossroads of carbon reduction transformation. The rigid electricity demand for continuous production is difficult to balance with the intermittent shortcomings of wind and solar new energy in the long run. The 100000 kW Inner Mongolia Energy Source Network Load Storage Integration Project, which started construction on August 21, 2026 in Bayi Village, Shanghai Temple Town, Etuoke Front Banner, provides a feasible industry sample. As the first project of its kind in Etuoke Front Banner, all the green electricity it generates is directly supplied to the nearby Hengkun Chemical Phase II for on-site consumption, without sending one kilowatt hour of electricity back to the public power grid.

Cracking the two major pain points in coal chemical industry through closed-loop system

The first phase of the project has a total installed capacity of 50000 kilowatts, including 30 megawatts of wind power and 20 megawatts of photovoltaic power. It is equipped with 15% of the total wind and solar capacity and 4-hour electrochemical energy storage, with an energy storage capacity of 7.5 megawatts/30 megawatt hours. It is also equipped with a booster station and a smart operation and maintenance center, and is scheduled to be officially connected to the grid in June 2027. Unlike the traditional logic of grid connection and consumption of ordinary new energy power stations, it deeply binds the power source and load from the beginning of design, completes dynamic scheduling through the smart grid in the factory, and directly supplies power for production when there is sufficient wind and light, stores excess electricity in energy storage, and supplements energy storage when output is insufficient, achieving on-site production and consumption of green electricity throughout the entire process.

This model accurately hits the two core pain points of the coal chemical industry, not only through the low price of green voltage and the low proportion of electricity costs, but also to achieve hard carbon reduction without crowding out the public green electricity indicators, while avoiding the power supply security risks caused by unstable power access to the plant.

Industrial symbiosis breaks free from the dilemma of two skins

The project has landed side by side with the recently completed ignition oven of Hengkun Chemical Phase II coke oven not far away, and behind it is a chain thinking of traditional energy production area transformation. In the past, many regions developed their own traditional and new energy sources, either due to difficulties in absorbing new energy and abandoning wind and solar power, or slow progress in reducing carbon emissions in traditional industries. However, this nearby direct supply system directly integrates high stability chemical electricity loads with green electricity supply, without long-distance transmission losses or occupying public grid peak shaving resources.

The chemical industry provides a definite consumption scenario for new energy, while new energy completes green empowerment for the chemical industry. The two have upgraded from simple physical addition to deep chemical reactions, fully implanting green genes into the traditional coal electrification industry chain.

We do not blindly pursue the scale of wind and solar installations that are detached from reality, but instead turn new energy into a production factor that drives the upgrading of physical industries. The exploration of Etuoke Front Banner provides a practical path for upgrading the stock of a large number of traditional energy production areas across the country.

After the project is connected to the grid in 2027, a continuous stream of green electricity will flow directly into the chemical production line. This transformation practice based on the industrial foundation will also provide replicable reference solutions for the green upgrading of more high energy industries.Editor/Cheng Liting
