As clean energy generation becomes more mainstream around the world, its variability and supply fluctuation begin to impact the electricity systems for which energy storage is a key factor. Storage can help even out spikes and dips in solar and wind resource availability and enable energy distribution to be shifted from the time of generation to the time of peak demand. There is no well-defined threshold level of renewable energy supply needed to ensure non-stop supply but in most cases, grid systems operators begin to invest in storage when 10 percent of their overall supply comes through renewable sources of wind and solar.

Over more than a decade, energy storage system vendors and battery manufacturers have been perfecting large-scale battery technology by extending its life cycle, toughening it to harsh environments, evolving management systems and, most importantly, continually driving down the cost. The industry has now reached a pivotal moment, with large storage systems becoming more competitive with other grid assets from a business perspective. The technology has been proven in the markets of North America and Europe, with several vendors offering competing technologies and solutions. What’s more, the capacity for installation and operation already exists. Back-of-the-envelope calculations show more and more cases of clean energy becoming viable in an ever-increasing number of markets. We can see that stationary storage has clearly begun its evolution from a niche solution to a mainstream grid asset.
