SECO News, April 2019



At year-end 2018, your not-for-profit cooperative served 205,644 members with reliable, safe, affordable power. The communities SECO Energy serves in our seven-county area are growing. You and your fellow members consumed over 3.14 billion kilowatt hours (kWh) last year – an increase of 184 million kWh over 2017.

SECO News Duncan's Digest 2019


We welcomed 5,161 new members in 2018. SECO invested over $3.3 million per month to maintain, inspect and build new infrastructure to reach new members and improve system reliability. The total investment in facilities tops $878.7 million.


Much of our growth can be attributed to The Villages expansion in Sumter County but other counties are prospering as well. 23% of last year’s new growth occurred in Marion County and 32% was attributed to Lake County. 43% of the growth falls in Sumter County, and SECO’s 2019 work plan aligns with that ongoing development.


This month, I’m highlighting a noteworthy system improvement project – the $3 million Federal substation expansion in Sumter County along County Road 501. Federal’s expansion is impressive – tripling its size – making it the largest in SECO’s territory to keep pace with growth in The Villages of Fenney, Southern Oaks and the Turnpike area.


The existing substation was rebuilt in 2017. A new control house was installed. The high and low side bus work was rebuilt, the sub was completely rewired and expanded foundations were poured.


In this state-of-the-art substation, we are adding two 56 MVA power transformers for a total of three, and building eight new distribution feeders for a total of 12 to serve more members. Federal serves 3,000 members – my home included. After expansion, capacity will increase ten-fold to potentially power 30,000 members’ homes.


Safeguarding this multi-million-dollar investment is a relay protection scheme programmed to protect the substation and power transformers to keep the sub operational. SECO Relay Technicians like Travis Taylor (who you’ll read about as this month’s SECO Champion) compute the limits feeders can distribute and the amount of fault current feeders can absorb and continue to operate safely.


Power transformers provide the proper voltage to members served by the substation. When unexpected outages occur, a car hits a pole or a tree falls on the line, relays operate and try to clear the fault/interruption detected on the line. A power blink is the relay scheme in action, interrupting power and restoring quickly. If the fault still exists after the blink, the relay shuts the power flow to protect the transformers as well as the downline breakers and equipment.


Like the substation itself, the relay scheme is high-tech. Federal will be equipped with an auto-restore scheme. If a power transformer is nonoperational, a transformer in the substation will automatically pick up the load in less than a minute. Thus, members may see a blink instead of a full outage. The transmission lines will be fully looped – meaning if a fault occurs on one side of the transmission line, another side will automatically pick up the load and members won’t know a problem occurred.


SECO’s 48 substations are inspected monthly. Crews visually inspect all material, run diagnostic tests and view equipment through an infrared camera that detects temperature variations. Equipment that is out of normal temperature ranges is inspected and replaced or repaired.


Along with monthly maintenance, substations undergo a major overhaul every eight years. Our techs test relays, breakers and transformers. Test records help build trends over time. Every year, a dissolved gas analysis is conducted on all substation power transformers. Techs take a sample of the oil found in the transformers and test for arcing, which is the first sign of failure. Samples are tested in-house at our mini lab and sent away for further analysis if dangerous gases are present and degradation is suspected.


Federal is one of many system improvement projects scheduled this year. The Marion Oaks substation is being completely rebuilt, and we’re upgrading the Ocala Park substation. Major maintenance is happening at the Clermont, Haines Creek, Inverness, Linadale, Mount Dora and The Villages substations.


Improving reliability and keeping power affordable for you and your family are top priorities at SECO.
