he 1960s saw advancements in transmitting and pooling electricity. Load dispatchers used the economic loading slide rule, which was the first analog computer at OUC. This helped them determine which units were the most “economical” to run during certain periods of time, based on factors like fuel cost and transmission availability.

As part of a national campaign launched by the electric industry, OUC participated in the Gold Medallion Home program, which touted the built-in advantages of “living better electrically.” Dwellings that were awarded this seal used “low-cost electricity” exclusively for “winter heat, summer cooling, year-around cooking and water-heating, as well as for light and power.”
