Amrapali Silicon City: Power backup ki kya situation hai?

Amrapali Silicon City projects are still a big question mark for many, honestly. I'm currently in a 2BHK in Greater Noida West, thinking of upgrading to a 3BHK or a small villa. Hearing mixed things about older projects. Full flat power backup ka kya scene hai? Common areas mein sab dete hain, but andar bhi reliable hai kya? Water supply ka issue toh nahi rehta wahan? Matlab, tanker pe depend hona padta hai kya? Elevators ka maintenance kaisa hai, response time kitna hota hai? Already home loan chal raha hai, need to be sure premium is justified. Real experiences, please share.
