Did you know there are 3 trillion trees on Earth? They are critical to our health because they absorb carbon dioxide and remove air pollution. Trees also provide shade, a home for wildlife, and beauty.
Yet vegetation around power lines is the No. 1 cause of fires and power outages worldwide.
Effective vegetation management is critical to maintaining sustainable, reliable, and safe electric transmission and distribution. Unfortunately, without the right technology, it’s time-consuming and expensive.
According to the Environmental Protection Agency, in the United States, there are 157,000 miles of electric power lines serving more than 131 million customers. With this much to oversee, proper vegetation management is vital.
What is vegetation management?
Vegetation management is the systematic oversight and removal of unwanted vegetation, including branches, trees, bushes, and weeds, around power lines. When vegetation interferes with power lines, it can cause fires and widespread power outages.
Based on Federal Energy Regulatory Commission (FERC)’s North American Electric Reliability Corporation’s FAC-003-4 standard, utilities must adhere to minimum requirements for vegetation management to prevent outages, including trimming trees and other vegetation encroaching on power lines. Additionally, they are pruned beyond the minimum clearance distance to allow for swaying in wind and growth. Power lines might also sag due to ice/snow build-up, heat, or high usage, so vegetation management plans must account for this reality.
Every utility develops its vegetation management plan to comply with federal, state, and local regulations in their services areas. FERC drives the electric transmission regulations, and local regulatory entities regulate distribution lines.
Why is vegetation management important?
Outages caused by vegetation aren’t just an inconvenience, they can be dangerous and costly. The largest blackout in U.S. history impacted 50 million people but also cost the American economy an estimated $7 to $10 billion. Proper vegetation management also:
Why manual inspection isn’t enough for vegetation management
Traditionally, vegetation management consisted of manually inspecting vegetation around critical network infrastructure quarterly to determine which vegetation needed to be cut. However, with an electrical grid as expansive as we have today, it’s impossible to catch all trees that need trimming before an incident occurs.
These traditional methods are ineffective and outdated.
Smart, efficient, and cost-effective vegetation management with technology
Vegetation management is one of the biggest expenses for utilities – it’s estimated utilities spend $6-$8 billion a year clearing vegetation from overhead lines. With technology and better insights from data analytics, utilities can reduce risk, increase visibility, and automate actions in their vegetation management programs.
One case study done by T&D World found these results when utilities transitioned from a time-based trimming approach to a risk-based one supported by drones, satellites, LiDAR, AI-driven technology, and big data analytics:
