I design control systems for grid scale battery systems that can operate as standalone power plants, or as hybrid power plants with solar, wind, or gas turbines.

Batteries essentially enable planners to increase renewable generation and make it less variable.

For gas plants, they can avoid or reduce the need to run gas turbines as peaking power plants which are typically needed to cover the significant gap between renewable generation and residential loads in the early evenings. The batteries can cover that period with energy shifted from the day to the late afternoons and early evenings.

Of course there is still CO2 emitted in their manufacturing, but I am coming from a previous career in making gas turbine control systems, so it's still an improvement. I'm trying to make the broadest impact I can as an engineer.
