The power supply station applied for increasing the store capacity, and the property was not proved.

When the power supply station applies for increasing the store capacity, if the property does not issue a certificate, it can try the following methods:

1. Submit the expansion application directly to the local power supply company and pay the corresponding expansion fee. In this case, no proof of real estate is needed.

2. If the reason why the property refuses to issue the certificate is that it is worried that the transformation of power facilities may have an impact on the property, you can try to communicate with the property to understand their concerns and try to solve them.

3. If the above methods are not applicable, you can consider seeking legal help or complaining to the local electricity regulatory agency.

Please note that specific practices may vary from region to region and specific circumstances. It is recommended that you know the local power management policies and regulations before taking appropriate measures.
