264 NEWSLETTER 2021 Recent Regulations Regarding Electricity Storage Activity* Can Yıldız Introduction Technology has evolved to the point, today, where we use the energy we obtain from different sources most commonly in the form of electrical energy. Electricity is an ideal form of energy through which to perform our daily tasks due to its ease of transfer and conversion to different energy forms. On the other hand, perhaps the biggest challenge we encounter in the use of electricity is that electricity cannot be stored - it must be consumed as it is supplied to the grid. This is because electricity, itself, cannot be stored on any scale; however, it can be converted to other forms of energy, which can be stored and later reconverted to electricity on demand. Storage systems for electricity include batteries, flywheels, compressed air and pumped hydro storage systems. That being said, any of these systems are limited in the total amount of energy they can store and are significantly inefficient. Thus, although these systems have historically been used on an industrial scale, they have had only a limited role in the general electricity network (i.e. the electricity network covering transmission and distribution networks). In the modern era, it is possible to say that electrical storage systems are designed to provide ancillary services to the transmission system, including frequency control.1 This is the main role of grid-scale batteries/ accumulators. * Article of May, 2021 1 In order for a power station to work, it must be preset. It is equal to the energy used in the power plant in the system. However, it will be related to the spike loads (consumptions). Likewise, large burdens (decrease in consumption) or strong developments also cause the previous one to go. When it is started to be used in a certain way, when it is exceeded, the minimum or possible users of the
