[LDES-coremodel] Battery storage cost projections

[Kenji Shiraishi]

Hi Sarah,

Thank you very much for the critical points. I used the "CAPEX" (M10 to
AR16), but I should have used power capital costs (such as AX20 through
something like BT20), instead.
The "CAPEX" that I used is the summary of both battery energy capital costs
and battery power capital costs. I misunderstood the definition of CAPEX.

I will revise the document tomorrow morning and send it to you. Annualized
power capital costs will be much closer to the number of RESOLVE.

Best regards,
Kenji
