I had a Grandfathered certification. Does that get automatically reinstated with my other certifications?

No, once any AEE certification lapses, it requires an individual reinstatement including the reinstatement fee for each certification.  Your certification director or training partner for those outside the US can provide the reinstatement requirements for all your lapsed AEE certifications.  Once your certifications have been reactivated, your Grandfather status can be reapplied to the certification.
