When the pioneer of science and technology meets photovoltaic and storage integration, what kind of green benefits will it create? A high-tech company in the South China Science and Technology Innovation Board has joined hands with a professional energy storage service provider, Homsun Electric Storage, to create a demonstration project of "photovoltaic + energy storage", using data to interpret what "every kilowatt-hour counts" in smart energy management.
A listed high-tech company in the Science and Technology Innovation Board in South China has put forward strict requirements for the stability and cost control of electricity for its large-scale intelligent manufacturing base:
Cost Reduction and Efficiency Improvement: The need to effectively reduce electricity costs, increase economic benefits, and improve the return on investment;
Backup Power Supply Demand: There is a rigid demand for backup emergency power supply to deal with emergencies and protect key equipment;
Expansion Limitation: Traditional power grids can hardly meet the dynamic expansion needs during the production peak season;
Dual Carbon Goal: As an industry leader, it needs to actively assume social responsibility and promote the low-carbon transformation of the industrial chain by building a green energy system.
Installation Scale: A 2.023MW distributed photovoltaic system covers 90% of the factory roof area.
Economic Benefits: The average annual power generation reaches 2.1005 million kWh, with a total power generation of 52.5118 million kWh in 25 years. The first-year revenue is 1.9834 million yuan, and the total revenue in 25 years reaches 47.2764 million yuan. It can break even in less than 2.5 years.
Environmental Benefits: The project uses idle rooftops to build photovoltaic power stations, which not only reduces the emission of carbon dust by 14,000 tons, carbon dioxide by 51,200 tons, sulfur dioxide by 1,500 tons, and nitrogen oxides by 770.75 tons, but also has the effect of keeping warm in winter and cooling in summer, extending the service life of the factory roof.
Equipment Configuration: 5 Homsun SP-215kWh energy storage cabinets (total capacity 1075kWh), equipped with lithium iron phosphate batteries and liquid cooling systems.
Economic Benefits: Through the implementation of a peak shaving and valley filling strategy, the electricity cost expenditure has been further optimized. The energy storage system (ESS) stores energy during off-peak hours (valley pricing periods) and discharges it during peak hours (high pricing periods), achieving load-shifting optimization. This strategy delivers an annualized revenue of RMB 389,300 and is projected to generate cumulative total revenues of RMB 7,786,200 over a 20-year lifecycle. The return on investment (ROI) for Years 1–10 reaches 41.53%, with the payback period not exceeding 2.5 years, ensuring full capital recovery within this timeframe.
Backup Power Supply Function:The energy storage cabinet always has 60 degrees of electric quantity as the emergency power supply for the enterprise, replacing traditional diesel generators, and is used for enterprise fire protection, emergency, and lighting purposes. The energy storage cabinet has a large capacity and high power, and can switch to the power supply state in 0.002 seconds, ensuring the continuous power supply of key loads and protecting precision equipment.
Optimizing Charging and Discharging Strategies: Extending battery life and improving economic benefits.
Smart Peak Shaving and Valley Filling:Dynamically optimizes charging/discharging operations to minimize electricity costs.
Real-time Fault Detection and Protection: Warning of hidden dangers, automatically cutting off faults, and ensuring safety.
Smoothing Power Fluctuations: Offsetting the intermittency of photovoltaic power generation and stabilizing power grid output.
Choosing Homsun Energy Storage is not only driven by the high efficiency, superior quality, and safety of their PV (photovoltaic) and energy storage products, but more importantly, by their EMS (Energy Management System), which enables seamless integration with production lines for intelligent control and management. This system achieves unmanned operation and remote monitoring/control, embodying the synergistic energy management model essential to modern manufacturing.
