Punjab State Power Corporation [PSPCL] — fluctuating electricity/low load of electricity

Address: Jalandhar, Punjab, 144005

Sir our house/societies electricity fluctuates a lot mainly at night and at mid time of the day. This affect the appliances badly and can damage them seriously. The meter is working fine and bill is also justified i. E bill is of proper amount as per the electricity consumed but the electricity is really dim most of the time. Sometimes, large appliances like ac don't even turn on. Please take a appropriate step to solve this problem. (As per my knowledge solution could be reached by either increasing the load or by changing the current wire by higher voltage wire).
