The cost of peaker electricity from battery farm storage is 30% less costly, including the new capital costs, than power produced from natural gas or diesel peaker plants - and that cost comparison is using costly Tesla battery pack mass-storage which can be built-out within a couple of months. Lithium-phosphate storage is even less costly but require a longer initial construction period, with redox-flow batteries becoming less costly still in use cases where power is routinely stored for more than 7 hours.

After several hours of continuous usage, newer gas/diesel turbine peaker plants can switch over to the cleaner and less costly high-efficiency burn mode used by plants in continuous operation. It's the lower temperatures achieved during short runs which make them more costly and higher emitting.

Decades older turbine or diesel engine plants produced more costly electricity with higher emissions no matter how many hours they are operated. If the hours of usage of this type of plant in Texas become too routine, most utilities would quickly replace these with newer turbines to lower electrical costs - but buying these turbines now come with multi-year lead-times due to demand which outstrips expanded production of new turbines.
