  • Cleco Power spent a total of $312 million on upgrades which included the most modern equipment – higher voltage transmission lines, structures that can withstand hurricane-force winds up to 130 mph, four new substations and other necessary equipment.
     
  • The upgrades were completed in three phases. The construction work for phase one began in 2010, and the various upgrades continued until the completion of phase three in 2021.
     
  • By completing the upgrades in phases, the company was able to control expenses.

  • With all three phases of the project complete, Cleco Power now has multiple interconnected transmission lines in the southern portion of its service territory that can withstand hurricane-force winds and meet customers’ growing power needs. 

  • Cleco Power’s entire transmission system also is stronger and more reliable. 

  • The company’s transmission planning group will continue to evaluate grid conditions and produce long-term forecasts of electrical demand to ensure safe delivery of power to customers.
