On an average a household uses 300 units to 400 units, comparatively the rates have been hiked up to 19-23% (Rs. 200/- to Rs. 395/-). These changes were in action from June 1st, 2016. These changes were made due to the competition between the great providers Tata Power, Reliance Energy & MSEB (Maharashtra State Electricity Board). Somewhere fighting to create monopoly for the electricity provider, they kept on increasing the charges and fluctuating it according to per 100 units every year making it hard for the common man.
RInfra Cable, being the lead cable provider for Tata Power & Reliance Energy charged 120% more on wheeling cost. RInfra states that the quality needs to be improvised to reduce the burning up of the towers. Previously the cables carrying out the supply charged Rs. 0.75/KWh to Rs. 1.23/KWh , now charges Rs. 1.24/KWh to Rs. 2.73/KWh. Providers do state that the households consuming less than or up to 300 units would be paying as they did before.
Wiremen or Meter-men, usually look after the wiring of the location. Some areas have older buildings that have been geared up with same wires for years. Old wires can sometimes cause to affect the meter readings, these wires are usually and mainly provided by the associated wiring provider. So, if your reading with a brand new says that you've used up to 300 units, the old and weathered wiring will show the reading up to 500 units due to overheating.
Similar to wire supply, Meters are fixed up with the agreement of the electricity provider. Meter-men are the ones who takes care of it. They have to provide a meter and record the readings per month, but due to the lack of attention to the meters and their running abilities, the readings are fluctuated. Hence, explains why the bill amounts fluctuates from high to low and vice versa.
The meter-men appointed by the provider company, have been paid with a 10% hike in salary since the new rates have been applied in 2013. Although the increase in salary haven't made them work as efficiently as they were supposed to. Regular check-ups of the meters, wiring, coordinating with the house owners and earthing issues have been ignored stirring things in a bad way.
