Technical FAQs 4

Why do we need a grid-scale energy-storage system?

Under some conditions, excess renewable energy is produced and, without storage, is curtailed 2, 3; under others, demand is greater than generation from renewables. Grid-scale energy-storage (GSES) systems are therefore needed to store excess renewable energy to be released on demand, when power generation is insufficient 4.

Are battery energy-storage technologies necessary for grid-scale energy storage?

The rise in renewable energy utilization is increasing demand for battery energy-storage technologies (BESTs). BESTs based on lithium-ion batteries are being developed and deployed. However, this technology alone does not meet all the requirements for grid-scale energy storage.

What is a grid-connected battery system?

The use of energy stored in a grid-connected battery system to meet on-site energy demands, reducing the reliance on the external grid. The gradual loss of stored energy in a battery over time due to internal chemical reactions, even when it is not connected to a load or in use.

What are energy storage systems?

Energy-storage systems designed to store and release energy over extended periods, typically more than ten hours, to balance supply and demand in power systems. Reduction of energy demand during peak times; battery energy-storage systems can be used to provide energy during peak demand periods.
