MATLAB: Reshaping 2d array

As in comment by Sebastian Bomberg's (for MATLAB >= R2016b):

% Let A - your data of energy (150120 x 5 double)
TT = array2timetable(A,'RowTimes',(datetime(2018,1,1,0,0,0):minutes(5):datetime(2018,12,31,23,55,0))');
TT_hourly_mean = retime(TT,'hourly','mean');

if MATLAB <= R2016a:

[y,m,d,h,~,~] = datevec((datetime(2018,1,1,0,0,0):minutes(5):datetime(2018,12,31,23,55,0))');
T = [table(y,m,d,h),array2table(A)];
T_hourly_mean = varfun(@mean,T,'GroupingVariable',{'y','m','d','h'});
