In recent years, international manufacturers have successively joined the RE100 initiative, committing to 100% renewable energy, while driving the green energy transformation of the supply chain. Delta has built an industrial and commercial grade energy storage system for the Pingtung chemical solvent recycling and treatment plant, complemented with an energy management platform for control and monitoring, successfully reducing the power contract capacity, maximizing the benefits of green electricity, and further assisting the client in building a green supply chain.

The chemical solvent treatment plant took advantage of its geographical advantages and set up a 2MW ground-based photovoltaic plant in the open space next to the plant for commercial operation. A 140kW solar energy system was subsequently built on the roof of the plant and carpark to generate green electricity for use by the waste solvent recycling facilities in the plant. After the construction of the solar energy system, Sanhsin Industry set its sights on the energy storage system, making good use of green electricity and optimizing the utilization rate of solar energy.

Delta integrated solar energy systems, energy storage systems with energy management to optimize power consumption in the plant

Delta provided one-stop service from the early stage system planning and evaluation to the maintenance and education training post construction. Supplemented by DeltaGrid® energy management system for integrated energy control and monitoring, Delta's industrial and commercial grade energy storage system solution included two 125kW power conditioning systems, three 176 kWh energy storage battery cabinets, which can store a total of 528 kWh of electricity. The application load transfer of this energy storage system improves the utilization rate of solar energy and optimizes the peak shaving of the plant, while the Delta DeltaGrid® energy management system integrates the municipal electricity, solar power generation, plant load and energy storage system, and converts all power supply and power consumption information into data.

This energy storage system was officially launched in May 2022, and coupling solar energy with energy management to control electricity consumption within the plant has yielded results. The contract capacity of the plant, which was set as 600kW, has now been reduced to 400kW through solar power generation and energy storage control. Over and above total avoidance of peak demand penalties, the monthly basic power expense was also lowered without affecting the operations of the plant.

At present, the production capacity of the plant is not fully loaded. Anticipating an increase in domestic demand for semiconductor waste solvent treatment, the client plans to expand the rooftop photovoltaic system to 300kW device capacity, and expand the energy storage system to 500kW/1056kwh, so as to generate more green power for use in the plant, and gradually become a 100% green power enterprise, progressing towards a goal which is aligned with RE100.
