Tamil Nadu Electricity Board [TNEB] — unnecessary power cut during night time

We are facing frequent unnecessary power cuts during day and night time. Day time we can manage somewhat, but how come during night time. There are aged person and new born baby at our home who are suffering a lot without proper sleep. Govt says that we have excess power in our state, then why these power cuts are happening. I'm writing this post during power cut in the midnight. There are two different distribution points in our area. The area which is nearby (Not more than 300mtrs) will not have such power cuts. We are also paying the same amount of bill amount like them for which we have utilised. Then why this partiality is shown. If somebody from the concern authority takes necessary action we will be very thankful.
