Negative balances and credits on JCPL bill?

Anyone ever see consistent credits and a negative balance on a JCPL bill monthly? Bought a new house about 8 months ago and have been seeing credits since May...about $50-60 monthly. No solar panels or wind or other energy generating components on the property from what I can see. No budgeting plans or anything, simply a new customer unsubsidized account.

I plan on calling this week but just curious if anyone's had the same experience?
