Sector 110: RWA and power backup reality check?

Sector 110, Noida Extension mein ek flat dekh raha tha. Builders bahut baatein karte hain power backup aur maintenance ki. But real picture kya hai? Kya yahan power cuts zyada hote hain? Honestly not sure if builders ki baaton pe trust kar sakte hain. Aur RWA charges kitne hain, are they worth it? Koi resident apna experience bata sakta hai?
