Minimization of Global Adjustment Charges for Large Electricity Customers Using Energy Storage—Canadian Market Case Study
Round 1
Reviewer 1 Report
Dear Authors,
the manuscript presented deals with an interesting topic: i.e., energy storage for the minimisation of the overall utility charges for a large customer. This topic has caught the attention of several researchers resulting in a wide literature review. I suggest to divide the introduction and the literature review (which need also to be extended). Furthermore, the introduction should be more focused on the motivation behind the study and on the main contribution (which can be highlighted also through the proposal of a summarising table underling the existing gap in the literature section). Other comments are listed below:
- in the nomenclature, it could be helpful for the reader the definition of the decision (independent) variables which should be optimised.
- an interesting paper could be ...
- Figure 1 is of a poor quality, please provide a clearer version
- At line 92, the Authors state that '.. a viable investment opportunity can be pursued'. Could you investigate more this concept?
- since the objective function is the minimisation of the overall utility charges, I'll be consistent with the terms (e.g., by avoiding "profit-maximisation" terms).
- The equations provided should be explained more, and references supporting them should be provided
- Is the hour an appropriate time step?
- The battery lifetime is influenced by a calendar raging and a cycling aging. The linear equation is a simplification. Could you provide at least a reference supporting this assumption?
- Could you provide a graph showing the load on a single day in different periods?
- Table 2 is not discussed. Some insights should be provided.
- Why reference [28] has been selected for the comparison?

Reviewer 2 Report
Please, clarify the advantages of the proposed methodology for the optimal sizing of BESS units that minimizes total energy costs, with respect to other works in the literature.
What does "kWh" indicate in "average weighted energy price (kWh)" in Fig. 1?
Provide a reference for the cost data in Table 1.
Improve the quality of Figure 4.
Include all measurement units in Figure 5.
In y-axis of Figure 6 it must be "kW" not "KW".

Round 2
Reviewer 1 Report
Previous comments have been addressed.
However, the format of the paper should be revised (i.e., check equations and figures)

Reviewer 2 Report
The paper still needs minor revision:
1) The authors should better clarify the advantages of their method with respect to the works in the literature.
2) Figures quality is very low.
3) Draw axes in all graphs.
