“…We included into the model the following regressors (Davidson et al, 2009): trend (t), dummies for the days of week (z (1) -z (6) ) and holidays (z (7) ), the share of working turbines at SayanoShushenskaya power station (essential due to the 2009 year catastrophic accident) (z (8) ), average day temperature (x (1) ) and light day duration (x (2) ) (The Weather Schedule, 2015), adjusted oil (x (3) ) and natural gas (x (4) ) prices (Market and analytics "Finam", 2015), dollar (x (5) ) and euro (x (6) ) exchange rates (Central Bank of Russian Federation, 2015), Russian GDP (x (7) ) (Rosstat, 2015). Some other regressors were excluded from the model due to their insignificant impact on electricity prices.…”
