The paper presents analysis of the most important methods for the estimation of the market power in the energy sector. In general, the methods based on concentration of electricity production and more advanced methods based on mathematical programming were assessed. Mathematical formulas of coefficient methods were presented. The methods based on equilibrium models (Cournot, Supply Function Equilibrium) were indicated as the most accurate for the application in the energy sector.
Metody szacowania siły rynkowej w sektorze energetycznym
siła rynkowa, oligopol, modelowanie matematyczne
Artykuł przedstawia analizę najważniejszych metod szacowania siły rynkowej w sektorze energetycznym. Przedstawiono zarówno metody oparte na wielkości produkcji i mocy zainstalowanej podmiotów funkcjonujących na rynku energii elektrycznej jak i bardziej zaawansowane metody wykorzystujące modelowanie matematyczne. Podano najważniejsze formuły matematyczne służące do obliczenia wskaźników. Jako najbardziej adekwatne do zastosowania w analizach siły rynkowej przedsiębiorstw energetycznych wskazano metody oparte na modelach równowagi (Cournot, Supply Function Equilibrium).
