For Your Comfort and Convenience
When the Derecho hit Central Virginia on the last day of June in 2012, the weather was hot and the damage was considerable. People went in search of ice to keep food cool and hauled fuel to power generators for a limited amount of electricity. Living without electricity is difficult and attempting to replace it is expensive and labor intensive.
That is why one of your Cooperative’s top priorities is reliable service. We even have a department of people who work on that every day so that you don’t have to … and they have a pretty good strategy:
1. Keep the lights on by reducing faults.
1. Keeping the lights on by reducing faults:
Most outages on the CVEC system are caused by trees growing outside of the 40-foot power line right of way (ROW) that fall into the ROW and onto or through the power lines. No longer isolated and insulated, the trees provide a path to ground for the electricity, which creates a short circuit.
In addition to our regular ROW maintenance work ($1.6 million annually) CVEC has added some new activities to keep the lights on:
Of the three strategies, keeping the lights on provides the greatest benefit to members, receives the majority of investment, and it is something that we work on every day.
2. Limiting the impact when faults do occur:
With 4,500 miles of power line flowing through rolling to rugged rural terrain, it should come as no surprise that trees are far and away the number one cause of outages, often in combination with a weather event. After trees, outages occur as a result of animals/birds, lightning, equipment failure, and actions by the public (auto accidents, tree cutting, farm equipment, etc.)
CVEC is working to increase the number of protective devices located along the distribution line to isolate faults when they do occur.
While fewer in frequency, when one of the transmission line companies drops the power feed to a CVEC substation, every member is instantly out of service and will be until service is restored by the Investor-Owned Utility that delivers energy to the CVEC distribution system.
3. Respond and repair as quickly as possible:
Too late! Snow falls, winds rage, trees topple, and the lights go out. Despite all of the planning and best efforts, outages will occur, particularly in Cooperative territories that have radial lines. Radial lines stretch from the substation, delivering electricity out to the end of the circuit, branching off as they go, with no alternate source of power. One downed tree may affect hundreds of members or it may affect half a dozen members. After a major weather event, there may also be hundreds of trees down that need to be cleared before all members will have service restored.
CVEC has worked to establish a quick response and repair process, including:
Keeping the lights on . . .
minimizing the impact and responding to outages
so members enjoy the good value of
comfort and convenience powered by electric energy.
