What is energy storage?

Wärtsilä compiled a dictionary that explains key industry terminology. Put simply, energy storage means capturing produced energy and saving it for later, for example in our lithium-ion battery systems, which are very comparable to the batteries in cell phones – just much larger.

What is an energy storage system (ESS)?

Energy Storage System (ESS) As defined by 2020 NEC 706.2, an ESS is “one or more components assembled together capable of storing energy and providing electrical energy into the premises wiring system or an electric power production and distribution network.” These systems can be mechanical or chemical in nature.

What are energy management systems?

Energy management systems are automation systems that collect energy data from the project site, and direct the battery energy storage to store or dispatch (discharge or empty) energy, thus enabling the efficient management of energy resources.

Why is energy storage important?

Energy storage is a critical component to the adoption and advancement of renewable energy sources around the world. When you have both your energy storage and balancing power honed to perfection, you achieve an optimised and flexible power system.

Is energy storage expensive?

In essence, when you have both your energy storage and balancing power honed to perfection, you achieve an optimised and flexible power system– and flexibility is vital in order to make the move to 100% renewable energy sources. One of the most persistent misconceptions about energy storage is that it is very expensive. Historically, it used to be.
