Turkey’s Power Grid
The electricity grid systems include three distinct components, often hundreds or thousands of miles apart—generation, transmission, and distribution. In many cases, the location of the generation and the concentration of the consumption of power are quite distant from each other. This has been the case in Turkey particularly when the country was hugely dependent on...
Assessing Spain’s Power Grid
The Spanish power grid is considered a legal oligopoly, with the most significant five large companies dominating 84.9% of the market in 2019.
