NASHVILLE — If you live in Williamson, Wilson, Rutherford or Cannon counties it’s possible you’re donating regularly to several different charities and don’t even know it.

Under something called Operation Round Up, the public Middle Tennessee Electric Membership Corporation rounds off its customers’ monthly bills to the next whole dollar amount and donates the difference to charity. In other words, if your bill is $49.25 you will pay an additional 75 cents for the charity of the utility’s choice.

Wilson County resident Dave Kirkey pays attention to his monthly bill and was already aware of the program when he spoke to Tennessee Watchdog Wednesday.
