Short answer
Yes, a little. Much less than “30 events” sounds.
Most events don't empty your battery, and a part-empty only counts as part of a cycle. Warranties already allow for this kind of use.
One cycle means filling and emptying the whole battery once. An event that uses 70% of your battery counts as 0.7 of a cycle.
6 to 12 events, each using about 70% of the battery
all 30 events, each emptying the battery completely
if your battery empties once every evening
Cycles per year. Even the most a VPP could add is small next to normal daily use.
Two things, working together. A VPP adds to the first one only.
Every full charge and empty causes a small, permanent chemical change inside the cells. A VPP means some extra emptying each year.
A battery slowly wears just by existing, even unused, and faster in heat. Joining a VPP doesn't change this.
Many warranties set a throughput cap: the total energy (kWh) the battery can move over its life. Your cover ends at whichever comes first: the number of years, or that energy total. This matters more than a simple cycle count.

Everyday use matters more
No, it's the opposite.
Charge you hold back for blackouts can't be used in the evening or sent in VPP events. If VPP earnings matter more to you than backup, keep the reserve as low as your outage needs allow.
In a blackout, a battery only keeps your home running with backup-capable hardware and a backup circuit fitted at install. Without both, it does nothing in an outage, VPP or not.
If the remaining limit easily covers the whole sign-up, the extra wear is a known, fixed cost, not an open-ended one. For the bigger picture, see is a VPP right for you?
