Smart Microgrids for Solar Energy Storage Helps Conserve Energy and Reduce Carbon Emissions to Achieve Dual Carbon Targets
To build an efficient low-carbon energy system, China has set dual carbon targets of peaking carbon emissions by 2030 and achieving carbon neutrality by 2060. Whether the industrial and commercial sectors in China, whose electricity consumption accounts for 64.8% of total electricity consumption, can succeed in low-carbon transformation is instrumental to the energy revolution that is taking place across the world. The government therefore encourages industrial and commercial electricity consumers to install solar energy systems and implement a two-part tariff for widening the peak-to-valley electricity price difference. The ultimate objective is to balance grid demand and supply by making factories’ energy self-sufficient and by lowering peak-hour electricity consumption. However, solar energy is intermittent, as it is not produced at all hours of the day, and its use is occasionally restricted by regulations.
Enhance Energy Efficiency with Smart Microgrid
Because of these issues, industrial and commercial sectors often experience challenges in energy transformation, such as an unstable power supply, increased cost of consumption, and inefficient operation. To combat the challenges in energy transformation, Delta Electronics installed smart microgrids for solar energy storage in two of its manufacturing plants in China, one located in the Wujiang Economic and Technological Development Zone (Suzhou City, Jiangsu Province) and
the other in Dongguan (Guangdong). The installed microgrids are adapted to regional seasonal conditions, electricity usage behaviors, and geological environmental conditions.
They are configured to first generate renewable electricity to support the power demand of the plant. The microgrids are integrated with a flexible energy storage-charging strategy to achieve peak-shaving and valley-filling and reduce demand, thereby lowering the cost of electricity consumption and improving energy efficiency.
Delta Electronics Plant in Wujiang:
Saves almost 1M RMB in Monthly Electricity Costs: Leveraging Demand Response for a Brighter Economic Outlook
Delta Electronics’ Wujiang Plant was built in flatland Suzhou in 1999.With an area covering 214,000 m2, it is the company’s largest R&D and manufacturing base in China, housing nine sub-plants and more than 30,000 employees. The plant usually consumes a considerable amount of electricity during peak hours, from 8 am to 7 pm, which is while peak-hour prices are in effect. With the smart microgrid system for solar energy storage (energy storage capacity: 3 MW/15.552 MWh;solar energy: 7.9 MWp), the plant saved nearly 1M RMB in electricity costs in August 2023 alone.
Furthermore, in July 2023, Wujiang Plant participated in a demand response service provided by a local power company. When the smart grid detects peak electricity consumption, the power company can condition the plant’s energy storage system for compensatory peak-shaving, thereby dynamically increasing grid capacity. In doing so, grid resilience is strengthened and the plant also generates an additional source of income from the demand response service. A brighter economic outlook can be anticipated as the government ramps up policies on energy storage system subsidies and electricity price adjustments.
Delta Electronics Plant in Dongguan:
Stored solar energy is almost sufficient to meet whole-plant electricity demand at specific times of the day, with surplus energy still available on weekends being leveraged to generate an extra source of income.
Whereas Dongguan Plant is located in a region with a vast hinterland, Delta Electronics’ Dongguan Plant sits on a narrow hinterland in Dongguan City, Guangdong, where sunlight is available for longer hours. Thus, a smaller energy storage system featuring roof-mounted solar panels was selected for the Dongguan Plant to occupy less space. During daytime production activities, some parts of the plant can be entirely powered by solar energy and by the energy storage system during peak hours. When demand is reduced on weekends, electricity generated from the solar energy system can be stored either in the grid to generate additional income or in the energy storage system to avoid wastage, thereby improving the efficiency of the solar energy storage system.
