It’s integral to understanding the long-term value of a solution, including flow batteries. Diving into the specifics, the cost per kWh is calculated by taking the total costs of the battery system (equipment, installation, operation, and maintenance) and dividing it by the total amount of electrical energy it can deliver over its lifetime.
Another development that can boost battery storage in Bulgaria is a recent update of national legislation to include battery energy storage systems as a component of the grid.
Bulgaria has installed between 40 MWh and 50 MWh of battery energy storge capacity to date. However, new national legislation as well as funds provided through the European Union’s Recovery and Resilience Facility (RRF) could add another 1 GWh of storage capacity over the next two years.
Battery Energy Storage Systems (BESS) are becoming essential in the shift towards renewable energy, providing solutions for grid stability, energy management, and power quality. However, understanding the costs associated with BESS is critical for anyone considering this technology, whether for a home, business, or utility scale.
