State Grid Zhejiang Electric Power Serves Cross-Border Plastic Enterprises for Sustainable Smart Manufacturing

"Our single machine can produce around 2,000 small accessories per day, and the production line runs continuously for 24 hours." After the Spring Festival, at the new plant of Zhejiang Jinmao Plastic Industry Co., Ltd., 40 intelligent injection machines are operating their mechanical arms. Newly molded plastic household accessories enter the conveyor belt, and about 50 workers are busy quickly assembling them.

Storage boxes, shelves, hand luggage... Searching for household items on various e-commerce platforms, one can find household goods designed, produced, and sold by Zhejiang Jinmao Plastic Industry Co., Ltd.. "We have doubled our equipment investment and increased the production efficiency by at least 50 percent.  An expected annual production of 2 million sets of fashionable household products will achieve an annual output value exceeding CNY 240 million." The company's leader Lin Liguo analyzed.

According to Jinmao Plastic, the company plans to gradually establish overseas product selection centers and overseas warehouses in countries such as Vietnam in Southeast Asia and Kazakhstan in Central Asia in 2025. The company aims to obtain exclusive authorization for domestic stations of major online stores, reach overseas consumers, and leverage the industrial brand products from Taizhou to trade globally.

"Enterprise production should not only achieve 'acceleration' but also wear a seatbelt'." Except for fully ensuring the safety and stability of the power grid, the power supply company has introduced a "physical examination package" for enterprises to resume production, including services such as infrared temperature measurement of equipment and power consumption efficiency diagnosis. Tailored policies for each enterprise help users optimize their power consumption plans.

"It is recommended to change the basic electricity fee calculation method from capacity-based to demand-based. If the current load remains unchanged and no additional power equipment is invested, it is estimated that costs can be saved by around 30,000 yuan per month," explained Guo Weinan, an employee of the power supply company. In addition, a distributed photovoltaic power station has been built on the roof of the factory area, covering about 6,000 square meters and connected to the grid for power generation. With an installed capacity of 1,799.49 kilowatts, it is expected to generate 1.79 million kWh of electricity annually, creating a win-win situation for "solar benefits" and "energy-saving and cost reduction."

Taizhou, Zhejiang, is the origin and distribution center of plastic products in China, with more than 10,000 plastic production enterprises and more than 2,000 mold production enterprises. It is known as the "Kingdom of Plastic Products" and the "Hometown of Molds." After the dual-carbon goals were proposed, many enterprises have transformed towards intelligence and low carbon.

The State Grid Zhejiang Electric Power Company has actively served the enterprises' needs on distributed photovoltaic projects. Not far away, Zhejiang Xinding Plastic Co., Ltd. has formed a virtuous cycle between the increased power demand caused by intelligent and green transformation. The 13,000-square-meter factory roof has become a "solar bank." "Currently, the installed capacity of photovoltaic projects totals 2,717.05 kilowatts, with an annual power generation of 2.67 million kWh last year. This year, additional energy storage installed capacity of 2MW/4MWh is expected to be connected to the grid in the first half of the year, constructing a new power ecology of 'photovoltaic-storage collaboration'."

"The transformer temperature is normal, and there are no discharge traces on the insulator." Wang Yining, an employee of the power supply company, recorded data and focused on "diagnosing" the internal management of electricity use, the main electrical wiring of the distribution room, and the power supply configuration within the enterprise. A comprehensive investigation was conducted on outgoing switches in the production workshops. At the same time, electricity safety knowledge was promoted to enterprises to enhance the safety awareness of production personnel and ensure safe and reliable electricity use for enterprises.

From the mechanical roar of smart workshops to the energy pulsating on photovoltaic panels, from the searchlights of overnight inspections to the data flow of cloud monitoring, in this land of private economy, reliable electricity and quality services are lighting up every production line, which is being converted into the core competitiveness of Made in Zhejiang. Subsequently, the State Grid Zhejiang Electric Power Company will continue to adhere to a customer-centric approach, actively serve the energy needs of enterprises, and contribute to high-quality socio-economic development through precise services, more reliable and higher-quality power supply and services.
