I was not thinking about oversupply into the retail market. I was thinking of have a higher percentage of their average MWh available to sell as C&I contracts as they can do more of that without penalty risks when there is a battery available. So if they contract say 80% instead of 60% for a given field and the wind dips below the (higher) contracted energy value on a given day, the battery can supply the power as contracted.
This would allow for more of the power to be confidently sold and at least provide a basis for improved credit rating if nothing else.
