In the prefecture-level city of Taizhou in East China's Zhejiang province, the Qianjin Chemical Co Ltd — which focuses on high-performance environmental protection dyes and related intermediates — has grown into an enterprise with a leading production scale and market share in the world.

As one of the city's green and low-carbon factories for the year 2023, the company — set up in February 2002 in Jiujiang district — has led the formulation of five national standards, 12 industry standards and one "Made in Zhejiang" group standard during its development.

But its operating cost is also very high, said Xu Zhiyong, director of the firm's electricity department, noting that now, they can save at least 200,000 yuan ($27,805) a year after making some scientific readjustment in production.

The local branch of the State Grid — the world's largest utility which shoulders a dual task of safeguarding the country's energy security as well as its economic lifeline — is offering the help.

Cao Yajia, a staffer from State Grid Taizhou Electric Power Co, said that to boost industrial development, electric power must come first, so her agency is trying to bring more optimized services to enterprise workshops and production lines, injecting strong impetus into their high-quality development.

On March 7, some of Cao's colleagues visited Qianjin Chemical for a thorough investigation of its electricity use, trying to aid in bolstering its production efficiency and elevating its energy saving.

"We came to explain our new policy of electricity prices determined by different periods, help analyze your energy bills and put forward suggestions for optimizing your electricity consumption," Chen Hanhan told the company staffers greeting them.

In the power distribution room, members of the service team carefully examined the power supply facilities, power equipment operation, distribution transformer load, switching of protective devices and insulation equipment.

"The switch temperature is normal," said Wang Jiangjie, while holding an infrared thermometer to inspect a bid to safeguard its safe use of electricity for production.

Meanwhile, another teammate issued a written rectification notice to the company, urging its staff to rectify some hidden dangers, such as the "replacement of fire extinguishers in the distribution room", to ensure safe electricity use.

After the check-up, Chen explained to the company staff that the 24 hours a day can be usually divided into peak periods —the period with high electricity demand — and valley periods — the period with low electricity demand.

"At present, your proportion of electricity consumption in the valley period is less than 50 percent, which is unreasonable. You can save 200,000 yuan each year in electricity consumption if you make minor adjustments to the 15,000-metric-ton production of the KN-R products," Chen said.

Chen also helped the company staffers to better forecast the electricity consumption in subsequent months and improve its forecasting accuracy, to help it reduce costs and raise efficiency.

"After listening to your explanation of the new policy, the adjustment direction of our production plan for a large industrial production like us is now clearer, and we thank you for your comprehensive consideration for us," said Xu Zhiyong.

Cao Yajia added that in the future, they will try to let the local enterprises clearly understand the better use of electricity, and save money, to aid their progress.

Administering three districts of Jiaojiang, Huangyan and Luqiao, three county-level cities of Linhai, Wenling and Yuhuan in addition to three counties of Tiantai, Xianju and Sanmen, Taizhou has over 6.06 million residents.

The prefecture-level city, which borders the East China Sea, is a well-known region for its prospering economy and rich culture.
