Enguri and Vardnili Hydropower Plants (HPPs) and Abkhazian Demand. A Difficult (and Costly) Puzzle for Georgia

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 co...

Water Losses and Operational Efficiency in the Water Sector: Observations and Proposed Policy Interventions

The large and chronic water losses characterizing distribution networks constitute one of the major challenges faced by Georgian water utilities. The water supply generates approximately 700 million cubic meters of non-revenue water (NRW) each year1, considering just the urban centers. High water loss rates create excessive operational costs for the utilities and result in undesirable operational inefficiency in the water supply sector. This creates obstacles — from a financial point of view — to the achievement of full cost recovery and to the appropria...

Do We Need to Worry About the Generation Deficit in the Electricity Market? And What Can Be Done About It?

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). This significant reversal has motivated us to explore ...

Why Everyone Should Pay to Use Water, and How This Could (and Probably Will) Be Done in Georgia

“At least we have a lot of water - why should I pay for it?” One can frequently hear this phrase in Georgia. This popular saying is based on the relative abundance of water resources the country has: roughly 15,597 cubic meters of renewable freshwater resources per capita a year, well above the 2,961 cubic meters per capita in the European Union (World Bank 2014). However, having a resource does not mean being able to use it, nor being able to do so in a sustainable manner. Georgia lacks infrastructure both for water supply and sanitation, providing drin...

Is There Need For a More Competitive Electricity Generation Market?

Why do we care about competitiveness in energy markets? And, what are the benefits of increased competition from the supply side of the electricity market? The main reason for the additional social surplus derives from increased energy consumption at lower prices. Increased competition in the electricity market is expected to translate into fewer market distortions – be they simply due to the abuse of market power or to the survival of inefficient firms – and, therefore, increased efficiency. Increasing the level of competitiveness in the electricity mar...

Increasing Electricity Imports and Jumping Import Electricity Prices: a Worrisome Development or Data Glitch?

  After the generation deficit of September, the decreasing trend in generation continues, while the gap between consumption and generation keeps widening. Chiefly, compared to September, total electricity generation has decreased by 8% in October 2018, while in contrast with the previous October, 2017, electricity generation has decreased by 5%. This reduction in generation on a yearly basis is specifically due to the decrease in hydropower (-1%) and thermal power generation (-17%), which more than offsets the increase in WPP generation (+4%). Wher...
