Georgia – Net Electricity Importer Again?

Several years ago the (now former) Georgian government started successful reforms in the electricity sector and was eagerly looking forward to future projects. The improvements made were evident. The rehabilitation of hydroelectric power plants (HPPs) and other structural reforms led to a gradual increase of hydro power generation and to the decrease of electricity imports and thermo power generation. From 2006 this helped Georgia to become a net exporter. By 2010 Georgia exported almost seven times more electricity (1524.3 GWh) than it imported (222.1 Gwh) and thermo power generation was reduced to 682.8 GWh. In 2010 hydro power generation (9374.9 GWh) made up 111% of domestic consumption (8441.1 Gwh).

The data for the last two years is, however, a bit disturbing. While domestic consumption continues to grow (with an annual rise of 9.7% in 2011 and 3.6% in 2012[1]), hydro generation has fallen quite dramatically. In 2011, hydro generation dropped by 15.8% compared to 2010, and in the first nine months of 2012 it continued to decline by 7%, compared to the same period of the previous year.

The growth of consumption and drop in hydro power generation naturally resulted in an increase of thermo power generation and electricity imports, and in a decrease of electricity exports. Thermo power generation increased more than three times in 2011 and, judging by the nine months of available data, it is likely to maintain this level in 2012. Imports increased more than two times (growing by 112%) in 2011 and in the first nine months of 2012 Georgia has already imported 422.45 GWh (a growth rate of 84%, which means that imports are going to almost double again). At the same time, exports decreased by 38% in 2011 and in the first nine months of 2012 Georgia exported only 527.6 GWh (a decrease of 40%). Considering the fact that the three months left in 2012 are winter months, when hydro energy is running on a seasonal low and imports grow accordingly, it is easily possible that, after a period of six years of being a net exporter, Georgia is now going to close the year as a net electricity importer.

At the first sight, it seems that something is wrong with Georgia’s hydro power generation; however, if we look more precisely, the situation might not appear so alarming. In 2011 government officials declared that it was a “dry year” after a “rainy year” (2010), and indeed, it should be noted that 2010 was a clear outlier. Thus comparing 2011 to 2010 is not quite fair. If we compare 2011 to 2009, we could actually say that hydro generation has continued to grow and there is nothing to worry about.

It is, however, the data from the first nine months of 2012 that leaves a disturbing impression. First, if 2011 was just a ”dry year” then what should we call 2012? “Even drier”? In any case, it seems that hydro generation in 2012 will be almost the same level as in 2009, which creates the impression that the existing working capacity of  hydro power has exhausted its ability of improve further.

So, the main challenge for the new government will be to continue the reforms of the electricity system and create incentives for investors to build up new capacities. The country is developing and consumption is growing and the new government’s claim is that they will accelerate this development. Accelerated development means an accelerated growth of consumption.

So let’s hope that the new government, and particularly the (likely) new Minister of Energy, former AC Milan footballer Kakha Kaladze, will be able to meet this challenge. Otherwise, Georgia will not be able to continue its ambition of being a net electricity exporter.

I've undergone a starting phase of depression until I reached paragraph 4. thanks for good post and expecially for its end.

Maybe extensive construction had a (negative) impact on power generation. I suppose there are HPPs that have been rehabilitated, temporarily taking them out of commission.

Michael,
there was not any announcement about such large rehabilitation in last couple years that could cause this. In the contrary, as I know, "Association Green Alternative" (Georgian environmental NGO) has been constantly requesting to rehabilitate old large hydro power plants (Enguri and Jinvali) instead of building new ones, but without any result.

Main reason of dramatic decrease in hydro generation is 2011 was drop of generation by two hydro power plants (HPPs). Total decrease in Enguri & Vardnili HPPs generation in 2011 compared to 2010 was 1186.6 mln which is 80% of total hydro generation reduction. In 2012 (nine months of 2012 compared to nine months of 2011) those two HPPs contributed only about 10% of total hydro generation reduction.

As part of the continuation of the power sector reform, the incoming government should look at the options and costs for diversifying the generation mix. Hydro power is good insofar as they are renewable energy sources, but the article points a key issue: the potential of this type of renewable to make a meaningful contribution to power generation in the winter period.
