2. Power purchase and sales business: Providing safe and stable power services is the core business of power sales companies. The difference between the purchase and sale of electricity by a power selling company is profit. Using the competition in the power generation market to reduce the cost of electricity purchase and using marketing strategies to attract more power customers are the fundamental methods for power sales companies to enhance their core competitiveness.
3. The same electricity sales company can sell electricity in multiple power supply business areas. There can also be multiple power sales companies in the same power supply business area, but only one company has the right to operate the distribution network. This company needs to provide guaranteed power supply service, that is, to provide guaranteed power supply to users who do not participate in the electricity market bidding.
