6 FAQs about [Energy storage system backup time requirements]

What is a battery energy storage system (BESS) & an uninterruptible power supply (UPS)?

Figure 1: A simplified project single line showing both a battery energy storage system (BESS) and an uninterruptible power supply (UPS). The UPS only feeds critical loads, never losing power.

Why is energy storage important?

Renewable sources of energy such as solar and wind power are intermittent, so storage becomes a key factor in supplying reliable energy. ESS also help meet energy demands during peak times and can supply backup power during natural disasters and other emergencies.

What is an energy storage system?

An energy storage system is something that can store energy so that it can be used later as electrical energy. The most popular type of ESS is a battery system and the most common battery system is lithium-ion battery.

What is the difference between rated power capacity and storage duration?

Rated power capacity is the total possible instantaneous discharge capability (in kilowatts [kW] or megawatts [MW]) of the BESS, or the maximum rate of discharge that the BESS can achieve, starting from a fully charged state. Storage duration is the amount of time storage can discharge at its power capacity before depleting its energy capacity.

What is a battery energy storage system?

A battery energy storage system (BESS) is an electrochemical device that charges (or collects energy) from the grid or a power plant and then discharges that energy at a later time to provide electricity or other grid services when needed.

Can energy storage systems be installed in certain areas?

Energy storage systems can pose a potential fire risk and therefore shouldn’t be installed in certain areas of the home. NFPA 855 only permits residential ESS to be installed in the following areas:
