The need to store electrical energy from renewable sources for use when a fixed power source is unavailable has led to many technological developments in the design of batteries over the years.
Sodium-sulphur (NaS) batteries are long-duration stationary batteries for many large-capacity grid applications. NaS provides superior functions and performance features possible only from decades of research, design, testing, demonstration, advanced manufacturing and over 20 years of proven commercial operation.

COVID-19 has led to lockdowns. That, in turn, has led to less energy use, creating an opportunity for renewables to shine. They are becoming the lowest-cost energy source on sunny days, although during the evening when electricity demand is high, power prices are spiking. (Forbes)
