There are three ways to sign up for electric service with GreyStone Power, online, by phone and in person at a GreyStone office. Please keep in mind that GreyStone connects and disconnects service Monday through Friday, excluding holidays.

Residential GreyStone members have a choice of two ways to pay, prepaid or post paid.

  •  Imagine prepaid like filling up your car with gas. The car goes until it runs out of gas, and it is filled up again.
    - Prepaid members pay for their electricity up front, and add money to their account as needed.
    - If the funds on the account are depleted, the electricity is turned off, but there are no reconnect or late fees.
    - The member puts more money on the account (enough to bring the balance to at least $10 above zero) to get it turned back on.
    - Prepaid members also get the added benefit of not having to pay a deposit.
    - To set up a prepaid account, please complete the online application.
  • Post paid is the traditional way to pay for power.
    - Residential or business members use electricity one month, and then pay for the amount they used the following month.
    - These members may be required to pay a deposit up front.
    - If the electricity is turned off due to non-payment, reconnect fees are required before service will be reconnected and additional deposits may result.
    - Members may set up new service online for post-paid service, or call 770.942.6576.
    - The deposit is returned after 18 months with no late payments.
