<p class="MsoNormal">Hi, Kenji,<o:p></o:p></p>

<p class="MsoNormal">This is a super nice summary.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m getting somewhat different results from the ATB.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">First, we might talk about whether 7% is still the right number for the discount rate.
<o:p></o:p></p>
<p class="MsoNormal">But, when I annualize the ATB numbers, I get substantially lower numbers than you do. I wonder if we are using different versions.<o:p></o:p></p>
<p class="MsoNormal">I see Capex in $/kW for 4 hr battery and 2 hr batteries in cells M10 to AR16.<o:p></o:p></p>
<p class="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.<o:p></o:p></p>
<p class="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.<o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>

<div>
<p class="MsoNormal">I have summarized the battery storage cost projection of NREL ATB 2020 as attached. <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">It would be great if you could skim it before our regular meeting. <o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="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.)<o:p></o:p></p>

<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="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.<o:p></o:p></p>
