6 FAQs about [Self-built energy storage power plant]

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.

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.

What is the configuration model of energy storage in self-built mode?

According to the above model, the configuration model of energy storage in the self-built mode is a mixed integer planning problem, which can be solved directly by using the Cplex solver. In the leased mode, it is assumed that the energy storage company has adequate resources to generally meet the new energy power plant’s storage needs.

How much does self-built energy storage cost?

For the self-built energy storage, the investment cost λ o w n p of unit energy storage power capacity and the investment cost λ o w n e of unit energy storage capacity are set as 3500 and 1000 RMB/kWh, respectively. The maintenance cost λ m of unit energy storage energy capacity is set as 40 RMB/kW. The service life L is set as 10 years.

Are self-built and leased energy storage modes a benefit evaluation method?

This paper proposes a benefit evaluation method for self-built, leased, and shared energy storage modes in renewable energy power plants. First, energy storage configuration models for each mode are developed, and the actual benefits are calculated from technical, economic, environmental, and social perspectives.

Which energy storage mode is best for new energy plants?
