System for accumulating verifiable energy demand data from remote electricity meters

A system for accumulating energy demand data from an electricity meter, comprising:

• memory means for storing demand data accumulated during predetermined time intervals;
• means for transmitting stored demand data from said memory means to a central computer over a telephone line;
• control means for rendering said transmitting means operative at a preselected time to initiate a communication to said central computer and to transmit said stored demand data to said central computer;
• command means for receiving control commands from said central computer over said telephone line during a communication between said system and said central computer;
• and
• override means for overriding said control means and for rendering said system responsive to receive said control commands in response to a communication initiated by said central computer.

A system for accumulating energy demand data from an electricity meter, comprising:

• memory means for storing demand data accumulated during predetermined time intervals;
• means for transmitting stored demand data from said memory means to a central computer over a communication channel at periodic time intervals;
• command means for receiving control commands from a central computer over said communications channel;
• an auxiliary battery power supply for supplying power to said system during power outages;
• low battery circuit means for detecting when said auxiliary battery power supply is failing and for providing a low battery signal to signal a low battery condition;
• and
• means for transmitting said low battery signal to said central computer over said communication channel.
