Georgia has made significant strides in the field of electricity generation, with over 80% of its electricity now coming from low-carbon sources. Specifically, between August 2023 and July 2024, hydropower contributed almost 80% to this low-carbon share, highlighting the state's robust reliance on clean energy. However, fossil fuels still constitute nearly 20% of Georgia's electricity mix, with natural gas accounting for this entire portion. As Georgia looks ahead, the next big challenge is electrifying other sectors such as transport, heating, and industry, which will demand even more electricity.
To meet the rising demand while maintaining and even increasing its low-carbon electricity share, Georgia can invest in expanding its current hydropower infrastructure, explore other forms of clean energy like solar and wind, and consider introducing nuclear energy. Nuclear power, in particular, offers a reliable and significant addition to clean energy supplies and can meet large-scale electricity needs without producing greenhouse gases. Furthermore, enhancing the grid infrastructure to better integrate various clean energy sources will be crucial for accommodating future growth and maintaining grid stability.
Reflecting on Georgia's history of low-carbon electricity, fluctuations in hydropower production have marked the past few decades. The early 1990s saw some declines, such as the 0.9 TWh drop in 1992 and the 1.6 TWh reduction in 1995. However, there have also been periods of growth; for instance, 2002 and 2010 witnessed increases of 1.2 TWh and 1.9 TWh respectively. More recent years continued this mixed trend with a notable rise of 1.9 TWh in 2021, followed by consistent but smaller increments. These figures indicate the potential for hydropower to continue playing a significant role in Georgia's clean energy future, though reliability and augmentation with other low-carbon sources like nuclear remains essential.
