WALTERS – Pennies, nickels, dimes and quarters – set enough of them aside on a regular basis, and the coins add up to dollars. That’s how Operation Round Up works. Most Cotton Electric members participate in ORU, in which power bills are rounded up to the nearest dollar. The amount rounded up can be as little as 1 cent and is never more than 99 cents. On average, each participating member contributes about $6 each year.
