Why is shared energy storage important?
Shared energy storage not only increases the amount of new energy power generation and eases the pressure on local power grids for peak regulation, but also assists the energy storage power station to achieve a revenue-generating model that obtains rental fees and profits from increased power generation.
What is shared energy storage & other energy storage business models?
Through shared energy storage and other energy storage business models, the application scope of energy storage on the power generation side, transmission and distribution side, and user side will be blurred. And many application scenarios can realize the composite utilization of energy storage according to demand.
What is the difference between shared energy storage and conventional energy storage?
Conventional energy storage projects serve a single renewable energy power station and the energy storage devices of each power station are not directly connected to each other. But shared energy storage considers all energy storage devices on the power generation side, transmission and distribution side and user side as a whole.
What is the role of energy storage in power generation?
The role of energy storage in the power generation side is mainly to improve economic and social benefits. It can compensate for the cost of building energy storage by reducing losses, reducing costs, and increasing revenue.
What is the difference between power grid and energy storage?
The power grid side connects the source and load ends to play the role of power transmission and distribution; The energy storage side obtains benefits by providing services such as peak cutting and valley filling, frequency, and amplitude modulation, etc.
What is user-side energy storage?
User-side energy storage can not only absorb renewable energy such as solar energy, but also maintain a stable power supply for houses. German energy supply company which called SENEC.IES adopts a “free lunch” energy storage business model. SENEC IES installs energy storage systems for users who own home photovoltaics.
