Electricity is a set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. When energy saving certain Periods are decided, some metres may measure, demand the maximum use of power in some interval. Record usage during peak high- cost and off-peak, lower cost. Electric utilities use electric metres installed at customers premises typically calibrated in building units.
Commercial use of electric energy become increasingly important than metre, similar to gas metres, required to properly bill customers, instead of billing for a fixed number of lamps per month. The reading of meter was proportional to actual energy consumed.

An early used in UK was the Reason metre. It is a vertically mounted glass structure with a mercury reservoir at top of metre. As current was drawn, electrochemical action transfered the mercury to the bottom, ones the Mercury pool was exhausted, meter become an open circuit therefore necessary for the consumer to pay for a further supply of electricity. Then the suppliers agent would unlock the metre, invert it restoring the mercury to the reservoir.
