Are you talking about battery storage itself being about $126/MW? Yeah, that incorporated into the solar+battery LCOE, because solar itself is $31, battery is $126, and the weighted average of how much energy is expected to come directly out of the solar panels onto the grid (at $31) and how much is expected to be stored for later ($31 plus $126) averages out to $53, presumably because most demand matches the daytime solar curve and doesn’t need to be stored for later.
