Abstract: Analysis of time-series of power loads in Europe is performed. Firstly, we detrend oscillations that naturally exhibit in the datasets then Multifractal Detrended Fluctuation Analysis is executed. We also performed additional tests -- shuffling of datasets and surrogated datasets -- to obtain valuable information regarding the autocorrelation function, the distribution function as well as robustness of the results with respect to non-linear affects. All datasets exhibit multifractality in the distribution function and the autocorrelation function. The difference is present in the width of multifractal spectra, where almost all states posses narrow multifractal spectrum with only few examples with the wide multifractal spectrum. We state a hypothesis that the width is entangled with structure of sources of electric energy.
