Hydro resources are one of Georgia''s most important natural riches. Approximately 300 rivers are significant for energy production, with total annual potential capacity of 15 000 MW and production potential of 50 TWh. According to GNERC, however, only 22.5% (3 380.2 MW) are used for hydropower. Georgia''s wind energy potential is estimated

Lead-acid batteries are currently the most mature battery system, with the lowest cost among electrochemical storage technologies. They have been used as backup batteries in power plants and substations for years, performing an extremely important role in the reliable operation of the power systems [61, 62].

Lead-acid (LA) batteries. LA batteries are the most popular and oldest electrochemical energy storage device (invented in 1859). It is made up of two electrodes (a metallic sponge lead anode and a lead dioxide as a cathode, as shown in Fig. 34) immersed in an electrolyte made up of 37% sulphuric acid and 63% water.

The deeper level comes from nuclear power units which provide electric power for EHS to generate heat. In Fig. 5, if the base load operation of the nuclear power plant has backup units, the output power of the backup unit will be provided to the EHS and the generated heat will be supplied to the heat load or stored in the EHS.

There are several unique benefits and challenges when integrating renewable energy sources and battery storage systems into a microgrid. A microgrid transmits and

Small-scale battery energy storage. EIA''s data collection defines small-scale batteries as having less than 1 MW of power capacity. In 2021, U.S. utilities in 42 states reported 1,094 MW of small-scale battery capacity associated with their customer''s net-metered solar photovoltaic (PV) and non-net metered PV systems.
