Woodbury County REC uses an Automated Meter Reading (AMR) system using the Two-Way Automatic Communications System (TWACS) meter module, which allows all electric meters to be read remotely.
The TWACS meters have an electronic circuit board module installed. The module receives and stores the Kilowatt-hour (kWh) consumption recorded by the electronics in the meter, and is able to transmit this and other data over the power lines to equipment located in the substations. From the substation the data is communicated over telephone lines or by satellite back to the TWACS computer at the Woodbury County REC office.
Using AMR/Twacs is both beneficial to Woodbury County REC and their members. Some of these benefits are:
