After reviewing the stylized facts about power markets we propose and fit various models to spot prices from german energy market EEX. Afterwards we assess their performance by comparing simulated and market prices. Our empirical study shows that (1) models with MRS are more realistic for spikes and jumps and (2) introducing herteroskedastiсity in the base regime model leads to better spike identification and goodness-of-fit than in MRS models with mean-reverting, constant volatility dynamics.</abstract><trans-abstract xml:lang="ru">Рассмотрены проблемы моделирования и оценивания спотовых цен на электроэнергию на основе марковских процессов с переключением режимов.
