What are the main uses of energy storage batteries

Battery energy storage systems (BESS) are transforming the way we utilize electricity. By reducing energy costs and increasing energy independence, solar battery storage improves the way we can generate, distribute, and consume energy. The primary function of BESS is to store energy in batteries and distribute any excess energy for future use.

This is Fortum's second pilot project using batteries as energy storage at its hydropower plant. In Landafors, a number of out-of-service batteries from Volvo Cars plug-in hybrids are used. Even if the batteries no longer have enough capacity to function in a vehicle, they can still be useful in electrical storage.

Battery energy storage systems provide several benefits to individuals and businesses: Cost Savings: Companies and homeowners can significantly lower their electricity bills by optimizing their energy consumption. Alternative energy savings methods such as peak shaving can greatly reduce overall energy costs for facilities or homes.

Energy storage systems allow energy consumption to be separated in time from the production of energy, whether it be electrical or thermal energy. The storing of electricity typically occurs in chemical (e.g., lead acid batteries or lithium-ion batteries, to name just two of the best known) or mechanical means (e.g., pumped hydro storage).

Battery electricity storage systems offer enormous deployment and cost-reduction potential, according to the IRENA study on Electricity storage and renewables: Costs and markets to 2030.

Lithium-ion batteries are preferred because they offer a long-life span, high energy density, and efficient performance during charging and discharging. In 2023, lithium-ion battery prices hit a record low, making battery storage a more reliable and cost-effective option for sustainable energy systems.
