The authors regret the data in Tables 2 and 3 of the manuscript have not been captured correctly. The corrected tables are presented below. The authors would like to emphasize that the changes in these tables have no direct impact on the outcome of the solution nor the discussions as confirmed in the code and demonstrated in the following examples: - EWH optimal solution as presented in the corrected table shows t25–t36 and t103–t112, t121, t122, this is in line with the graphically presented results in Fig. 1. Hence it does not affect Fig. 2 results. - The optimal operation status of ‘Dishwasher’ shows the optimal results of t118–t120 and these are also in line with Fig. 1. - ‘Tumble dryer’ has optimal switching status of t118–t120. It has also been confirmed with other appliances that do not appear in the figure. The overall corrections do not have impact on the results of both Figs. 1 and 2. The authors would like to apologize for any inconvenience caused.
