After blocking in; the pilots obviously shut down the ground power upon their departure from the aircraft. I was in the aft galley saying goodbyes to our customers and a couple of people had to use the lav's before deplaning and said to me 'there is no light in the lav' when the door was closed and locked. It was also stifling hot in the back where we were congregated. NO AIR!! I went to call the Flt Deck and the purser and there was no way to use the intercom. Then I tried to use the PA. Of course NOTHING. This has happened to me a number of times before when the ground power has been shut down; the airplane was still at least 3/4's full from my vantage point. My concern is/was; what if there was a medical emergency? What if there was a fire? Many situations could potentially happen and there is/was no way to communicate with the front of the aircraft; to the Flt Deck or the FAs in the forward cabin. I don't think a megaphone would handle the communication needed for an emergency!
Air carrier Flight Attendant reported a complaint with company procedures that permit pilot crews to shut down all power after parking at the gate with passengers still deplaning.
