It's an excellent summary. Can you please tell me how you calculated the annualized cost for RESOLVE. I did some calculations, and I found the attached data. You might take a look!</div>

N.B. I have considered the discount factor 7% and lifetime 15 years.</div>

<p class="x_MsoNormal">Hi, Kenji,</p>
<p class="x_MsoNormal"> </p>
<p class="x_MsoNormal">This is a super nice summary.</p>
<p class="x_MsoNormal"> </p>
<p class="x_MsoNormal">I’m getting somewhat different results from the ATB.</p>
<p class="x_MsoNormal"> </p>
<p class="x_MsoNormal">First, we might talk about whether 7% is still the right number for the discount rate.
</p>
<p class="x_MsoNormal">But, when I annualize the ATB numbers, I get substantially lower numbers than you do. I wonder if we are using different versions.</p>
<p class="x_MsoNormal">I see Capex in $/kW for 4 hr battery and 2 hr batteries in cells M10 to AR16.</p>
<p class="x_MsoNormal">Then, I see that someone has used those numbers to derive both $/kWh and $/kW with those being listed in cells AX10 through something like BT22.</p>
<p class="x_MsoNormal">If I use the 4 hr battery numbers I get something like what you get, but if I use the $/kWh and $/kW that are on the far right, I get different numbers.</p>

<p class="x_MsoNormal">Hi all,</p>
<div>
<p class="x_MsoNormal"> </p>
</div>
<div>
<p class="x_MsoNormal">I have summarized the battery storage cost projection of NREL ATB 2020 as attached. </p>
</div>
<div>
<p class="x_MsoNormal">It would be great if you could skim it before our regular meeting. </p>
</div>
<div>
<p class="x_MsoNormal"> </p>
</div>
<div>
<p class="x_MsoNormal">Based on their scenario description, Moderate scenario seems appropriate as the base case scenario of SWITCH. Costs in Moderate scenario is about 2/3 of current SWITCH model. It is partly because of the difference in lifetime (ATB assumes
15 years, while SWITCH assumes 10 years.)</p>
</div>
<div>
<p class="x_MsoNormal"> </p>
</div>
<div>
<p class="x_MsoNormal">The costs inputs of RESOLVE are much lower than those in Advanced scenarios of ATB. I would like to talk about the units of the cost inputs in the next meeting.</p>
