Phase Change Electricity Usage + Monopolized Electricity Pricing？

2026-2-04

    This is a customer operating a Tesla repair shop in Zhuhai. Their electricity usage involves a special "phase change" consumption method, while local power resources are monopolized by the village, resulting in electricity prices that lack market fairness, reaching as high as 1.5 RMB per kWh. The high electricity costs have become a heavy burden on the business operations, severely compressing profit margins.

    To solve this challenge, the customer independently invested in and installed a distributed photovoltaic system, paired with a 261kWh large-capacity energy storage system, creating an integrated "solar + storage" power supply solution. Additionally, the customer set up household charging stations to meet daily electricity needs and employee charging requirements. Through the implementation of this combined solution, the customer's monthly electricity costs were directly reduced by half, effectively lowering operational expenses and enhancing business profitability.

   Given the significant success of the current solution, the customer plans to further expand the PV installation capacity after the New Year and add an additional 261kWh energy storage unit. This will further enhance energy storage capacity and power self-sufficiency, ultimately achieving "energy independence"—fundamentally breaking free from high electricity costs and minimizing reliance on the external grid.
