3. Electric storage heaters vs. gas heating systems. Storage heaters have advantages of their own: the pirrice and installation costs are low when compared with those of central systems, and its installation is far easier and inexpensive. Besides, compared to gas central heating systems, storage heaters have very low (next to zero) maintenance
In general, the initial cost of an energy storage power station mainly includes the investment cost of the energy storage unit, power conversion unit, and other investment costs such as labor and service costs for initial installation.

With increased energy planning needs and new regulations, environmental agencies, state energy offices and others have expressed more of an interest in electric power sector models, both for (a) interpreting the results and potential applications of modeling from other groups, and (b
Operation and cost of electricity purchase have a high influence on storage cost. • The ratio of charging/discharging unit power and storage capacity is important. • PSH and CAES are low-cost technologies for short-term energy storage. • PtG technologies will •
3. Types of storage and recent developments. Storage has played an important role in balancing electricity supply and demand since the beginning of electricity systems. Depending on the characteristics of a specific type of electricity storage, it can be used for different purposes and provides various services.
