Gov. Charlie Crist and his Cabinet on Tuesday gave the green light for the siting of Progress Energy Florida's nuclear power units in Levy County.

The governor and Cabinet served as a siting board in the long process of approval leading to the actual construction of the sites.

This portion of the approval process involved the company's site certification application (SCA). The SCA includes a detailed analysis of the potential environmental impacts of the proposed plant and related transmission lines. Yesterday's vote was the second of three major approvals needed before the company can begin building the nuclear plant.

In July 2008, the Florida Public Service Commission approved the "needs case" for the plant. The last remaining major decision is from the Nuclear Regulatory Commission (NRC), which is expected by early 2012.

Progress Energy Florida owns about 5,100 acres in southern Levy County for the potential construction of two nuclear reactors. If built, the new plant would employ approximately 800 full-time, high-paying positions, generate another 1,000 to 2,000 indirect jobs and employ about 3,000 people at the height of construction, the company says.

Progress Energy filed the SCA with the Florida Department of Environmental Protection in June 2008. After review by the Department of Enviornmental Protection and a series of public hearings, an administrative law judge supported approval in spring 2009.

Earlier this year, the company announced an adjustment to the construction schedule for the Levy plant that shifted the timetable from the original in-service date of 2016 by a minimum of 20 months. The company is continuing to pursue the Levy County project. A new project timeline depends on negotiations currently under way with the engineering, procurement and construction vendors.

Progress Energy says despite what is expected to be a short-term economic downturn, the company's service area in Florida remains one of the fastest-growing regions in the country. As the fourth-largest state, Florida ranks third nationally in per-capita energy consumption. Over the past three decades, the average size of a new home has grown by nearly 50 percent and uses 30 percent more electricity. Since the Crystal River nuclear plant came online in the mid-1970s, the company's customer base has more than doubled, the company says.

If approved and built, the project would be among the first nuclear plants in the country to be constructed on a greenfield site in more than 30 years, and would involve development of one of the single largest transmission infrastructure projects in Florida's history.

For it's part, Progress Energy is happy about Tuesday's outcome. "This is an important milestone for the proposed Levy plant," said Vincent M. Dolan, Progress Energy Florida's president and chief executive officer. "Carbon-free nuclear power is a strategic asset in our statewide effort to become energy-independent, to reduce our reliance on more volatile-priced fossil fuels, and to provide a balanced approach to meet the challenges of growth and climate change."
