FKEC GENERAL INFORMATION

Florida Keys Electric Cooperative (FKEC) is the private, non-profit power utility for the Upper and Middle Florida Keys. Headquartered in Tavernier, Florida, FKEC provides electricity from the Seven-Mile Bridge to Ocean Reef and the Monroe County Line, and services more than 33,000 meters. FKEC presently has an authorized workforce headcount of 123, with an actual headcount of 120. FKEC recognizes the Union as the exclusive collective bargaining agent for all employees of FKEC working in the Union classified positions. Employees are divided between two work locations: Tavernier and Marathon, and among nine departments: Executive, Finance, Human Resources, Safety, Engineering, Information Technology, Transmission, Distribution, and Member Services.

The Cooperative was formed as a corporation in the state of Florida in 1940, and in 1944 was recognized by the Internal Revenue Service as being federal income exempt tax under section 101(10) of the Revenue Act of 1939 (now section 501 (c) (12) of the Internal Revenue Code). FKEC currently imports all of its power supply and uses local generation for emergency back-up only. The utility relies on power from the mainland because it is far less expensive than local generation.

Today, FKEC maintains a highly respected position within its local community, and within the National Rural Electric Cooperative Association, for its dedication to reliable electric service and forward thinking initiatives.

FKEC and its representatives have exercised due care in preparing this Request for Quote (RFQ). All information contained herein is believed to be substantially correct. However, bidders should verify information independently if desired. FKEC and its representatives do not warrant the accuracy of information contained herein.
