The reality is much more complex than "batteries replace gas" -
> Developers can no longer use financial modelling that assumes gas power plants are used constantly throughout their 20-year-plus lifetime, analysts said.
> Instead, modellers need to predict how much gas generation is needed during times of peak demand and to compensate for the intermittency of renewable sources that are hard to anticipate.
> "It does become more complex," Nigel Scott, head of structured trade and commodity finance at Sumitomo Mitsui Banking Corporation, said.
> Investors are putting increased scrutiny on the modelling, he added.
- so basically, maintaining a large-scale grid is an optimization problem. And batteries merely shift the answer to "how much of which each type of equipment should we have?" around some. Kinda like someone architecting a DC-scale system has to understand trade-offs between L1 cache / L2 cache / L3 cache / local-to-core RAM / more-distant RAM / SSD / HD / Tape - vs. what equipment is actually available - at what prices, lead times, configuration limitations, ...
