Low incoming voltage

Any way to increase incoming voltage?. I am constantly at 109-111V during most of the day. I just happen to be on a leg with many Cannabis factories here in Mich and my local electric service provider (DTE) says this is the main reason. 
I do not think I will get any relief from them and will probably be ok when the weather cools, but very frustrating when I don't have enough juice to efficiently run a pair of monoblocks in a room I just built for listening.
Any ideas on how to increase voltage?.  I have  native 200 amp service.  
Thanks for any input,
Russ
