Duke Announce Plans for Utility-Scale Solar Investments in Florida

LCG, April 2, 2015--Duke Energy Florida plans to add up to 500 MW utility-scale solar power in Florida by 2024. The proposal is included in Duke's 2015 Ten-Year Site Plan provided Tuesday to the Florida Public Service Commission (FPSC). Construction of the first site will begin later this year.

"Innovative investments in solar energy will provide customers with more options to use this resource, while diversifying our energy mix and continuing to meet the needs of Florida's growing economy and population," said Duke Energy Florida???s state president.

The initial project will be up to five MW, with 35 MW expected to be completed by 2018. Duke Energy Florida will use these initial solar projects as a basis to evaluate costs and monitor the effects of this resource on the electric grid infrastructure.

In addition to the solar investments, Duke Energy Florida plans to install a 1,640-MW combined-cycle natural gas plant in Citrus County. The first 820 MW block of capacity is expected to come online in spring 2018, and the second 820 MW block is scheduled to commence operations by the end of 2018. In addition, the company will upgrade its combined-cycle Hines plant in Polk County and purchase Calpine's 590-MW, gas-fired Osprey plant (also in Polk County). The investments will enable the company to meet needs for additional generation beginning in 2018 and to retire half of its Florida coal-fired fleet in 2018.??

The utility-scale solar investments by Duke Energy are not new. Over the past eight years, Duke Energy stated that it has invested more than $4 billion in wind and solar facilities in 12 states, including the company's Stanton Solar Farm located in Orange County. The company plans to invest $2 billion to $3 billion in renewable energy in the next five years.
