Electric Reliability

As a community-owned, not-for-profit utility, JEA works hard to provide reliable services in an environmentally friendly way at a fair price. To us, reliability means when you wake up on a cold morning and turn up the heat or take a hot shower, the power is there for you – and everyone else in our four county service territory. It means in August, when the temperature is 95-degrees and the humidity makes it feel higher still, you can relax in air-conditioning with a cool drink to watch T.V.

Electric power takes planning and maintenance on a grand scale. And it requires vigilant compliance with federal rules, laws, regulation and industry standards. Our reliability record is one of the best in the industry, in part because we are diligent about responsible tree trimming. We also employ the latest technologies not just to maintain – but to improve – our reliability record. And we are among the best utilities in the nation when it comes to compliance with Reliability Standards.

The Price of a Power Pole

Utility poles are the backbone of JEA’s electric infrastructure. In FY16, JEA inspected more than 18,000 distribution poles and replaced some 3,500 of them.  Just one wooden pole and the hardware attached to it costs about $1,680. With 120,000 wooden and concrete poles in our city, that amounts to a sizable investment in electric infrastructure and doesn’t even include our investment in high voltage transmission lines!

Wooden poles such as the one above are found on most residential streets in Jacksonville. Match the number to the list below to see how much each pole can cost.

The Price of a Pole
  1. Pole: $300
  2. Transformer: $850
  3. Animal Guard: $6
  4. Animal Guard: $13
  5. Crossarm: $150
  6. Lightning Arrestor: $45
  7. Switch Bracket: $70
  8. Fuse Cutout: $75
  9. Secondary Line: $100

CEMI-5
We use a lot of acronyms in the utility business and CEMI-5 is one of the big ones. It stands for Customers Experiencing More than 5 Interruptions of one minute or more in the past 12 months.   

Vegetation Management
Once we get that CEMI-5 metric in hand, we target a fix to improve a customer’s electric reliability. This often includes tree trimming.

Compliance Standards
JEA must comply with strict federal reliability standards or be fined up to $1 million per day. Understand those standards and why there is a need for them.  

Reducing Outages Due to Lightning

Since 2012, JEA has replaced 70 miles of static wire in approximately 15 high voltage transmission circuits. The static wire protects the phase conductor from direct lightning strikes, which reduces circuit outages and equipment damage. 

Facility Maintenance

JEA's Brandy Branch electricity generating plant improves reliability with planned outages. Planned outages help technicians find small problems before they become big ones.
