BESS asset life isn't great so a longer paypack period runs up against product life. Without running the actual model (volume, frequence and price differential) its tough to tell how quick it happens though I am sure I could build that relatively quickly if I wanted to (assuming granularity of public data).

My main point is that its a very large asset so you can't external forces come and mess up the financials (such as policy, regulatory changes, or large infra jump in that area) to make good on that bet. Certainly some public dollars being put to work to de-risk the bet.

These standalone batteries are typically privately financed.

Private finance normally lined with some low cost public money, especially at this size.

If it is straight up privately financed even more of a big bet.
