Right, so that means that to produce 300MW reliably from the solar or wind farms you'd need about 900MW nameplate capacity. I'd be really curious about the solar side of it too and whether that 30% is overall or just during daylight. Either way, you end up having to overprovision the unreliable sources such that you have enough capacity to both charge your battery pack and provide power to the grid.
30% overall, including night time. Honestly seems high to me and makes me wonder if they have overprovisioned panels vs the maximum allowable injected power to get a better capacity factor.
