More on Last Week's Florida Power Outage

For those who have not heard what the cause was:
A Florida Power & Light engineer not following proper procedure was the sole cause of Tuesday's massive power outage that left millions without electricity throughout the state for a few hours, FPL officials said Friday.

...

FPL President Armando Olivera said a preliminary investigation found that not one customer would have lost power had proper procedure been followed. The engineer, who Olivera refused to name, disabled two levels of relay protection, while diagnosing a piece of malfunctioning equipment. When the equipment short-circuited, there were no protective measures in place.

...

The engineer was working on a piece of equipment that controls voltage at the Flagami substation in West Miami. While he was diagnosing the problem, an arc -- originally thought to be a small fire -- occurred and melted some of the equipment. Since the protective relays had been disabled, there was nothing in place to contain the problem.

...

Olivera said changes in how protection relays were governed are already in place. He also said that once a full investigation is complete, the North American Electric Reliability Corporation (NERC) would conduct a review of the findings.
According to Annex B of the World Energy Outlook 2006, 25 percent of the world's population had no access to electricity in 2005. While the brief Florida outage was an inconvenience, everyone should recognize that 1.6 billion people live in this world every day without access to the benefits of electricity.

Anyone want to take odds on those who blamed the outage on the Turkey Point reactors going offline coming forward to admit their error? My guess is those would be pretty long odds.

My question is this: who was the supervisor and manager for the engineer who made a mistake? It's easy to find a scape goat. Is that what this is? problems like this usually happen because of lack of procedures, training and management oversight. It's very rare for one lone engineer to go itby himself and "wing it", but if he wasn't nuclear trained, I suppose it's possible. I just want to see his manager take some accountability if there is accountability to be shared. There are too many scape goats.

I wouldn't mind the electric utilities cutting off electricity for a month to radical environmentalists who want to shut down power plants. Both at their homes and their work.

The engineer wasn't working at a nuclear station - he was somewhere out in the power grid at a major switching station. When the slow-clearing fault spread its effects outward into the system, the nuclear reactors went down due to the severe effects on voltage and frequency. It is common to let experienced engineers work on difficult problems - after all, they are the 'experts' and he should have known better than to disable the second 'backup' level of protection.

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…

Nuclear Is a Long-Term Investment for Ohio that Will Pay Big

With 50 different state legislative calendars, more than half of them adjourn by June, and those still in session throughout the year usually take a recess in the summer. So springtime is prime time for state legislative activity. In the next few weeks, legislatures are hosting hearings and calling for votes on bills that have been battered back and forth in the capital halls.

On Tuesday, The Ohio Public Utilities Committee hosted its third round of hearings on the Zero Emissions Nuclear Resources Program, House Bill 178, and NEI’s Maria Korsnick testified before a jam-packed room of legislators.


Washingtonians parachuting into state debates can be a tricky platform, but in this case, Maria’s remarks provided national perspective that put the Ohio conundrum into context. At the heart of this debate is the impact nuclear plants have on local jobs and the local economy, and that nuclear assets should be viewed as “long-term investments” for the state. Of course, clean air and electrons …
