What is a self-built energy power plant?
In the self-built mode, it is assumed that the new energy power plant independently owns and manages its energy storage system, with sufficient financial and technical resources to fully cover the investment, construction, maintenance, and operational costs.
Which energy storage mode is best for new energy plants?
Despite the extensive research on energy storage configuration models, most studies focus on a single mode (such as self-built, leased, or shared storage), without conducting a comprehensive analysis of all three modes to determine which provides the best benefits for new energy plants.
What is the difference between self-built and leased energy storage?
In the self-built mode, the new energy power plants themselves are both the owner and the user of the energy storage, meaning the storage system is constructed and operated by the power plants. In the leased mode, the energy storage is owned by an energy storage company, while the new energy power plant acts as the user.
