“This project officially started on June 25, 2021. After 132 days of intense construction, 7,780 photovoltaic panels were installed. On the afternoon of the first day of grid connection, more than 5,000 kWh of electricity was successfully generated.” On November 23, Festo Pneumatic Jiang Zuolin, general manager of the Co., Ltd. and vice president of operations in the Greater China business area, told reporters that the combination of the automatic scrubbing robot planned in the future and the inverter that converts it into the factory’s usable AC power constitutes the entire photovoltaic system of Festo Jinan factory.


It is understood that Festo, headquartered in Germany, is committed to pneumatic and electric drive automation product solutions. Its global production center set up in Jinan has a total planned area of ​​about 430,000 square meters of factory area, with intelligent production workshops, automation Core areas such as logistics center and dual system training center. This “smart aircraft carrier” uses a huge amount of energy every day. How to make the sustainable development of the enterprise run through the entire enterprise value system, Festo has been practicing.

Jiang Zuolin said that due to the characteristics of sunshine, the peak of photovoltaic power generation is precisely the time when the power supply is the most tense. “The power we store during the day will show a powerful function during the time period of power outage or power shortage. The photovoltaic power station has a great relief effect on the power supply situation around the factory during peak periods.” According to estimates, the project After being connected to the grid, Festo can provide 5 million kWh of green electricity every year, reducing carbon dioxide emissions by about 4,000 tons.


“Low-carbon environmental protection, Festo has been taking action. As the world’s leading supplier of automation technology, Festo has long been committed to climate protection and optimization of carbon footprint. We are also actively studying to further expand the proportion of green energy in the later stage, in order to provide global While reducing carbon emissions and fulfilling social responsibilities, Festo’s energy expenditure has also been reduced, and the power supply security of the Jinan factory has been improved.” Jiang Zuolin said that in addition to the use of solar energy, Festo also deepened its sustainable development practices in other aspects. , Jinan Global Production Center has implemented measures such as rainwater recycling, reclaimed water recycling, and heat energy recycling, and has achieved more than 80% of outer packaging recycling, reducing resource waste.


Strong commercial market willingness


In addition to developing rural photovoltaics in Dezhou, Binzhou and other places, Shandong Lesun Photovoltaic Technology Co., Ltd., which is mainly engaged in the design, installation and after-sales service of distributed photovoltaic power plants, has also served many enterprises and commercial customers.


“There is a local raw chicken slaughtering plant in Zouping. Initially, we considered that we could build solar panels on their breeding plant. The cooperation model is to rent their platform. We also told them that we could sell our electricity to them, but once At the beginning, enterprises were not interested in solar photovoltaic power generation and electricity purchase.” Xu Mingzu, general manager of Shandong Lesun Solar Technology Co., Ltd. told reporters that electricity prices were charged in steps later, and there was a cold storage for raw chicken slaughtering, which required 50,000 kWh of electricity a day. The average price of industrial electricity is 0.85 yuan/kWh, and the electricity bill is as high as 42,500 yuan in one day.


In order to save electricity costs, the factory took the initiative to find Xu Mingzu this time. “After negotiation, we sold it to them at 0.65 yuan/kWh, and due to the increase in the capacity of solar panels, we can now supply 15,000 kWh of electricity to the factory every day, helping them save electricity costs and saving 3,000 yuan a day in electricity bills.”


Using the existing sites of businesses, enterprises or factories to build distributed photovoltaics is now more common in cities, suburbs and even rural areas. According to data from the National Energy Administration, as of August 2021, the cumulative installed capacity of photovoltaics in my country has reached 275.13 million kilowatts, accounting for 12.05% of the installed power generation capacity in the country. From January to August 2021, the newly installed photovoltaic capacity in China was 22.05 million kilowatts, an increase of 6.88 million kilowatts compared with the same period last year, showing a continuous growth trend.


“After years of investment and calculation, we found that if commercial enterprises invest in distributed photovoltaics, they can basically recover the cost in three years, and the service life of distributed photovoltaic equipment is 30 years, which is equivalent to net profit income in the next 20 years. “Xu Mingzu said that the threshold for building own equipment is not high at present, and it can take advantage of the existing building roof. The electricity price of distributed photovoltaic power plants is lower than the industrial and commercial settlement price, which is more attractive to industrial and commercial enterprises with rooftop resources. It can truly provide high-quality photovoltaic power for commercial power customers, greatly reduce energy expenditure, and establish long-term benefits. This is the significance of distributed photovoltaics including self-built power stations in the commercial market.


Encourage self-built photovoltaic power stations


In order to effectively promote the implementation of my country’s “dual carbon” goal, the low-carbon transformation of the energy structure is imperative. In the future, the proportion of clean energy such as wind power and distributed photovoltaics in primary energy consumption will increase significantly, and may gradually become the most important energy sources. source of supply. For commercial and industrial electricity use, how to achieve carbon reduction goals more reasonably and sustainably has become a compulsory course for enterprises.


“The market transaction price of high energy-consuming enterprises is not subject to the 20% limit, which is to make enterprises with more electricity consumption and high energy consumption pay more. The reform plan for on-grid electricity price for coal-fired power generation released on October 15 will help In order to promote energy transformation. After the on-grid electricity price fluctuates greatly, it will promote the market’s willingness to develop new energy to a certain extent, such as some enterprises building distributed photovoltaic power stations by themselves.” said Yu Guangming, deputy director of the Industry Department of China Photovoltaic Energy Industry Research Association. The next step should be to carry out green power transactions, realize direct transactions between users and wind power and photovoltaic power generation projects, guide green power consumption in a market-oriented way, promote the development and consumption of green power, and then better promote the construction of new energy systems.


Zhang Mingsen, chief expert of the Beijing Chemical Research Institute, said that to achieve carbon peaking and carbon neutrality, on the one hand, the consumption of fossil energy must be gradually reduced, and on the other hand, the proportion of renewable energy must be effectively increased. He suggested that relevant incentive policies should be formulated to promote high-power-consuming enterprises to build photovoltaic power stations and wind farms, and to achieve carbon reduction goals by increasing the proportion of renewable energy use.


The reporter learned that there are already many industrial, manufacturing and high-energy-consuming enterprises in Shandong Province that have successively self-distributed power plants or built photovoltaic power stations using the site, which can not only alleviate the power shortage situation of the enterprises themselves, but also can not be used up. Electricity can also be connected to the grid or laid out in advance for corporate green electricity trading, green certification and carbon reduction.


Industry insiders analyzed that the current exploration of enterprises to develop self-built power stations requires the support of relevant policies. For example, the theoretical installed capacity of distributed photovoltaics on industrial and commercial rooftops in my country is not less than 300 GW. %, if the relevant policies are improved, the future development potential will be greater.


Yu Guangming believes that with the continuous advancement of electricity marketization, financing and listing will be more stringent for corporate carbon information disclosure and carbon emission restrictions. In the next step, he suggested that Shandong enterprises can truly make clean electricity a compulsory course for enterprises by building their own power stations or building distributed photovoltaic power stations.
