Narrative:

We flew from ZZZ1 to ZZZ. After landing; as we taxied towards the gate; we shut down the #2 engine and started the APU. Then we got a huge electrical glitch. The airplane entered the 'electrical emergency mode' and the 'loss of all generators mode.' we lost many airplane system; including steering; EICAS indications; ahrs; dc busses; and lots of other system. Basically; the only things that worked were the engine and 1 radio. We then shut the airplane down twice and restarted it. After the second restart; the airplane returned to the normal electrical confign; although we still had many system missing. But we got the steering/hydraulics back and were able to taxi in to the gate. We coordination all our actions with ATC and for a time I think we were declared 'a disabled aircraft on the taxiway.' at the gate; we shut the airplane down again; and restarted it. At this point; everything returned to normal. We did all of our cockpit checks; including first flight items and a thorough preflight. Everything was normal. I discussed this event with dispatch and maintenance control and we all concurred that the airplane was safe to fly. We then loaded up passenger and returned to ZZZ1 uneventfully.

Title: E145 FLT CREW EXPERIENCES MULTIPLE ELECTRICAL SYSTEM ANOMALIES UPON SHUTTING DOWN ONE ENGINE AND STARTING THE APU FOLLOWING LNDG.

Narrative: WE FLEW FROM ZZZ1 TO ZZZ. AFTER LNDG; AS WE TAXIED TOWARDS THE GATE; WE SHUT DOWN THE #2 ENG AND STARTED THE APU. THEN WE GOT A HUGE ELECTRICAL GLITCH. THE AIRPLANE ENTERED THE 'ELECTRICAL EMER MODE' AND THE 'LOSS OF ALL GENERATORS MODE.' WE LOST MANY AIRPLANE SYS; INCLUDING STEERING; EICAS INDICATIONS; AHRS; DC BUSSES; AND LOTS OF OTHER SYS. BASICALLY; THE ONLY THINGS THAT WORKED WERE THE ENG AND 1 RADIO. WE THEN SHUT THE AIRPLANE DOWN TWICE AND RESTARTED IT. AFTER THE SECOND RESTART; THE AIRPLANE RETURNED TO THE NORMAL ELECTRICAL CONFIGN; ALTHOUGH WE STILL HAD MANY SYS MISSING. BUT WE GOT THE STEERING/HYDS BACK AND WERE ABLE TO TAXI IN TO THE GATE. WE COORD ALL OUR ACTIONS WITH ATC AND FOR A TIME I THINK WE WERE DECLARED 'A DISABLED ACFT ON THE TXWY.' AT THE GATE; WE SHUT THE AIRPLANE DOWN AGAIN; AND RESTARTED IT. AT THIS POINT; EVERYTHING RETURNED TO NORMAL. WE DID ALL OF OUR COCKPIT CHKS; INCLUDING FIRST FLT ITEMS AND A THOROUGH PREFLT. EVERYTHING WAS NORMAL. I DISCUSSED THIS EVENT WITH DISPATCH AND MAINT CTL AND WE ALL CONCURRED THAT THE AIRPLANE WAS SAFE TO FLY. WE THEN LOADED UP PAX AND RETURNED TO ZZZ1 UNEVENTFULLY.
