I know this isn't Volt specific, but this will likely get noticed here vs. a geography specific subforum (mods - move as you see fit). Anyway, I don't have any specifics as the TERp website hasn't been updated as of yet, but Texas had a $2500 rebate a couple of years ago that did not get renewed...until now it appears. I assume the "rules" will be the same as last time (i.e. tiers, leases are eligible, and Teslas are NOT eligible since they are not "sold" in Texas). Some details here:
