Senior citizens and disabled veterans on a limited annual income once again are eligible for a discounted monthly power bill.

Keys Energy Services this week opened enrollment for the discount program, which is available to residents 62 and older and to American veterans who are "totally or permanently disabled," according to a statement from the utility. Annual household income cannot exceed $30,396, which is a figure based on the maximum benefits paid by Social Security, the statement said.

Once qualified and accepted into the program, customers will receive a $9.53 discount on their monthy energy bills.

Applications for the discount must be received by March 31. Customers who previously qualified and received the discount must apply again, emphasized Julio Barroso, spokesman for Keys Energy.

Applications for the program already have been mailed to previous participants, Barroso said, adding that completed applications must be notarized if they're not completed at the Keys Energy offices.

New applicants may pick-up an application form at KEYS' offices in Key West at 1001 James St. or by visiting www.keysenergy.com or calling 305-295-1090 to request an application be sent by mail.
