Winter has always been a problem for the Georgian electricity system. Even though Georgia has plenty of hydropower, during this season several HPPs — seasonal and small — either stop or substantially reduce electricity generation. In this season, a significant share of hydropower generation comes from two large-scale state-owned pumped-storage HPPs: Enguri and Vardnili. However, exactly when the generation-consumption gap is the largest, most of the electricity produced is used to satisfy the consumption of the Abkhazia region, which on a yearly basis consumes as much electricity as Tbilisi, something we have mentioned in one of our previous articles.

In February 2019, Georgian power plants generated 939 mln. kWh of electricity (Figure 1). This represents a 0.5% increase in total generation, compared to the previous year (in 2018, total generation in February was 934 mln. kWh). Increase in generation on a yearly basis comes from increase in thermal and wind power generation (+26% and +24%), more than offsetting the decrease in hydro power generation (-14%).

Looking at annual consumption and generation trends, from 2012-2016, it is clear that generation typically exceeded consumption. Consequently, the generation-consumption gap remained positive. However, in 2017 this trend reverted, and the electricity generated by local resources on the Georgian market was no longer enough to supply the local demand. As shown in Figure 1, the gap widened even further in 2018; with the negative gap increasing by 30% (from 344 mln. kWh in 2017 to 447 mln. kWh in 2018).

In January 2019, Georgian power plants generated 1011 mln. kWh of electricity (Figure 1). This represents a 0.3% decrease in total generation, compared to the previous year (in 2018, total generation in January was 1014 mln. kWh.) The decrease in generation on a yearly basis comes from decrease in hydro and wind power generation (-11% and -18%), more than offsetting the increase in thermal power generation (+22%).

In 2018, Georgian power plants generated 12 154 mln. kWh of electricity. This represents a 5% increase in total generation, compared to the previous year (in 2017, total generation was 11 531 mln. kWh) (Figure 1). The increase in generation on a yearly basis comes from increase in hydropower (9%), more than offsetting the decrease in thermal (-5%) and wind power generation (-4%).
