The measures introduced to reduce the greenhouse gas emissions that cause climate change, which is recognized as one of the most important global problems of the 21st century, have brought about a significant transition in energy policies. This transition, based on the pillars of energy efficiency, electrification, and renewable energy sources, is critical not only for achieving climate goals but also for the security of energy supplies and affordable access to energy, thanks to the advances in technologies and declining costs that accompany such a transition. As a result, the transition of energy systems with sustainable energy sources is among the priorities of governments and international organizations around the world. Robust renewable energy targets also require increased flexibility in electricity systems, where supply and demand must always be in balance. Large-scale implementation of battery energy storage systems is expected to contribute significantly to this balancing process.
Various electrochemical materials used in battery energy storage technologies offer different advantages and disadvantages depending on their applications. Therefore, it is essential to plan and design battery energy storage systems to meet the needs of the region and to fit the intended purpose (arbitrage, management of generation plant imbalances, frequency regulation, etc.). In this context, the study aims to analyse the spatial distribution of battery technologies across Türkiye, the services to benefit most from their use, and their effects on the transmission grid so that batteries can be utilised efficiently as an instrument to increase flexibility in a wider effort to maximise the use of renewable energy potential in Türkiye.
