1. Metering apparatus for an electrical energy distribution system having a power generating station and a plurality of consumer stations interconnected by a power line, said metering apparatus comprising:

  • an electric meter at each consumer station, said meter including means for recording consumption of electricity in units of energy, control circuit means for adjusting the meter operating speed to vary the relationship between the number of energy units recorded by said meter and the number of energy units actually used by the associated consumer station;

    control signal generating means associated with said system said control signal generating means comprising means for measuring the aggregate power demand of the consumer stations in the system, means for generating control signals representative of said power demand and means for coupling said control signals into said power line;

    control signal detector means at each consumer station including coupling means connected to said power line, means connected to said coupling means and responsive to said control signal for operating said control circuit means to adjust said meter operating rate in a predetermined relationship to the overall level of power demand in the system; and

    display means for indicating both the level of overall system demand and the rate at which units of electrical energy are being recorded by said electric meter.
