A Persistent Negative Generation-Consumption Gap, a Puzzle to Be Explored

Looking at consumption and generation trends, it is evident that since August 2018 consumption typically exceeded generation. The negative generation-consumption gap also remained throughout April, amounting to 45 mln. kWh, with a total power generation of 966 mln. kWh and a consumption of 1,012 mln. kWh. Yet why has the generation-consumption gap remained negative since August 2018? Should we also expect the negative gap to persist over the following months? Figure 1. Generation-Consumption Gap A negative generation-consumption gap in April is a relati...

Does Your Smartphone Make You an “Unconscious” Villain?

Our dependence on smartphones can hardly be described as anything other than addictive. We invariably use them to document trips and thus to have the world at our fingertips. Though, these precious little gadgets have a dark history that we, as consumers, unconsciously support. Unfortunately, we will not be able to discuss in detail all the negative impacts within the supply chain of smartphones. Nonetheless, we wish this article to serve as an awakening, and a reminder, of what we as consumers are promoting. Moreover, what we - and governments - could d...

What Can Be Learned from the Experiences of the Khadori 3 HPP Project?

News of the conflicts between the local population and the construction company involved in the construction of a small HPP in the Pankisi valley (Khadori 3) has recently made it into the headlines. Khadori is a small HPP with an installed capacity of 5.4 MW and an estimated annual generation of 27.5 mln. kWh. Construction of the Khadori 3 HPP started on 21 April, however, the local population resisted the project, and consequently its company involved law enforcement officials to ensure its secure implementation. This further increased tensions between ...

Net-Metering: A Realistic Green Solution to the Generation-Consumption Deficit?

In February 2019, Georgian power plants generated 939 million kWh of electricity, which compared to the previous year represents a 0.5% increase in total generation. On the demand side, consumption amounted to 1,037 mln. kWh, a 2% decrease on an annual basis. Although the negative gap between generation and consumption decreased by 22% (from -126 to -98 mln. kWh), compared to the corresponding month of the previous year, it remained substantial. It is worth highlighting, once again, that this negative gap does not wholly reveal the extent of dependence o...

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...

William Nordhaus’ Models – a Dubious Equation for the Climate Debate

In preparation for the COP24 climate change conference in Poland, in December 2018, researchers published a report from the Intergovernmental Panel on Climate Change (IPCC) outlining how significant the consequences of climate change would be following a global increase in temperature of just a half degree, from 1.5 to 2 degrees C. In the wake of the newly released IPCC report, alongside William Nordhaus’ Nobel Memorial award, this year’s winner in economics, a heated debate has surfaced. This has come about not only with the instigators in Sweden publis...
