Moreau-Grand Electric Cooperative Today
From its m

eager beginnings in the late 1940's the cooperative has grown into a modern electric utility. Technology has been the largest impact on the utility industry. Modern hydraulics on our service vehicles have saved countless man-hours and prevented numerous injuries. The use of fiberglass in the equipment helps keep outages to a minimum and line crews safe. Electronics is another area where the cooperative has benefited from technology. Computers have changed how we enter member information and keep records. Early record keeping and office work was kept in hand written paper ledgers. Staking sheets and maps were meticulously hand drawn. A card system was followed by 5 computer systems. Some were so loud that it was necessary to carpet the walls to keep the sound down. In the late 1990’s the cooperative migrated from member read meters to a type of meter and computer system that could read member usage and send the reading back to the office on a daily basis. Radio controlled remote switching enables the cooperative to minimize outage time. All of the progress made during the last six decades would not have been possible without the cooperatives most valuable asset, its member owners. From the members who formed and continue to believe in the cooperative spirit, to the board members who make the tough decisions and employees who keep the lights on. Working together we shine as one.
