Sattva Lake Ridge power backup, what's the actual story?

Sattva Lake Ridge mein power backup ki reality kya hai? Brochures toh 'full flat backup' bolte hain, but actual mein kitna milta hai? Sirf common areas ya AC bhi chal jaata hai? Investor view se, ye tenant attraction ke liye kitna matter karta hai? Lagta hai maintenance mein toh full charge karenge, service kaisi hogi?
