FPL Finds New Nuclear Units at Turkey Point Still Economical

Last week, Florida Power & Light, subsidiary of NextEra Energy, submitted their annual filings on the need for two more nuclear units at its Turkey Point station. The units are projected to come online in 2022 and 2023. Below are a few highlights from one of the filings (pdf), p. 4:

assuming the same medium fuel cost, “Environmental II” scenario, FPL expects that Turkey Point 6 & 7 will:

  • Provide estimated fuel cost savings for FPL’s customers of approximately $1.07 billion (nominal) in the first full year of operation;
  • Provide estimated fuel cost savings for FPL’s customers over the life of the project of approximately $75 billion (nominal);
  • Diversify FPL’s fuel sources by decreasing reliance on natural gas by approximately 13% beginning in the first full year of operation;
  • Reduce annual fossil fuel usage by the equivalent of 28 million barrels of oil or 177 million mmBTU of natural gas; and
  • Reduce C02 emissions by an estimated 287 million tons over the life of the project, which is the equivalent of operating FPL’s entire generating system with zero CO2 emissions for 7 years.

And on page 11:

As described by Dr. Sim, Turkey Point 6 & 7 also continues to be a cost-effective addition for FPL’s customers, taking into account all updated assumptions. FPL’s analysis of Turkey Point 6 & 7 was performed by calculating a “breakeven capital cost” - the capital cost amount FPL could spend on new nuclear and breakeven with what it would spend for a combined cycle resource addition on a CPVRR [cumulative present value of revenue requirements] basis - and comparing it to its current project non-binding cost estimate range. The breakeven costs are higher than FPL’s cost estimate (i.e., the results are favorable) in six out of seven fuel and environmental compliance cost scenarios analyzed, and in the seventh, the breakeven costs are within the non-binding cost estimate range.

Accordingly, Turkey Point 6 & 7 continues to be an economically sound choice for FPL’s customers. Additionally, as explained by Mr. Scroggs, the Turkey Point 6 & 7 project remains feasible with respect to other, non-economic considerations.

For their detailed analysis, see FPL’s testimony from Steven Sim (pdf). In it, you can find their updated capital cost assumptions which are $3,483/kW to $5,063/kW in 2011 dollars (page 49 of 107). As well, pasted below are their assumed costs for natural gas in nominal dollars (page 41 of 107).

The capital costs for a new nuclear unit and the fuel price of natural gas are two key factors in determining the competitiveness of nuclear. Even with a huge glut of gas in the country, new nuclear is still found to be economical.

Knowing What You’ve Got Before It’s Gone in Nuclear Energy

The following is a guest post from Matt Wald, senior director of policy analysis and strategic planning at NEI. Follow Matt on Twitter at @MattLWald.

Nuclear energy is by far the largest source of carbon prevention in the United States, but this is a rough time to be in the business of selling electricity due to cheap natural gas and a flood of subsidized renewable energy. Some nuclear plants have closed prematurely, and others likely will follow.
In recent weeks, Exelon and the Omaha Public Power District said that they might close the Clinton, Quad Cities and Fort Calhoun nuclear reactors. As Joni Mitchell’s famous song says, “Don’t it always seem to go that you don’t what you’ve got ‘til it’s gone.”
More than 100 energy and policy experts will gather in a U.S. Senate meeting room on May 19 to talk about how to improve the viability of existing nuclear plants. The event will be webcast, and a link will be available here.
Unlike other energy sources, nuclear power plants get no specia…

Making Clouds for a Living

Donell Banks works at Southern Nuclear’s Plant Vogtle units 3 and 4 as a shift supervisor in Operations, but is in the process of transitioning to his newly appointed role as the daily work controls manager. He has been in the nuclear energy industry for about 11 years.

I love what I do because I have the unique opportunity to help shape the direction and influence the culture for the future of nuclear power in the United States. Every single day presents a new challenge, but I wouldn't have it any other way. As a shift supervisor, I was primarily responsible for managing the development of procedures and programs to support operation of the first new nuclear units in the United States in more than 30 years. As the daily work controls manager, I will be responsible for oversight of the execution and scheduling of daily work to ensure organizational readiness to operate the new units.

I envision a nuclear energy industry that leverages the technology of today to improve efficiency…

Nuclear: Energy for All Political Seasons

The electoral college will soon confirm a surprise election result, Donald Trump. However, in the electricity world, there are fewer surprises – physics and economics will continue to apply, and Republicans and Democrats are going to find a lot to like about nuclear energy over the next four years.

In a Trump administration, the carbon conversation is going to be less prominent. But the nuclear value proposition is still there. We bring steady jobs to rural areas, including in the Rust Belt, which put Donald Trump in office. Nuclear plants keep the surrounding communities vibrant.

We hold down electricity costs for the whole economy. We provide energy diversity, reducing the risk of disruption. We are a critical part of America’s industrial infrastructure, and the importance of infrastructure is something that President-Elect Trump has stressed.

One of our infrastructure challenges is natural gas pipelines, which have gotten more congested as extremely low gas prices have pulled m…
