A typical ESS project is designed and estimated to work for 10 to 15 years. However, the services it is supposed to provide are profitable for only a few months or in good cases, up to two to three years. After that, either the market gets saturated and very low income can be expected or the policy makers introduce a new grid service with a
China''s distribution network system is developing towards low carbon, and the access to volatile renewable energy is not conducive to the stable operation of the distribution network. The role of energy storage in power regulation has been emphasized, but the carbon emissions generated in energy storage systems are often ignored. When

Pumped hydroelectric energy storage stores energy in the form of potential energy of water that is pumped from a lower reservoir to a higher level reservoir. In this type of system, low cost electric power (electricity in off-peak time) is used to run the pumps to raise the water from the lower reservoir to the upper one.
