The $140 million investment in 2014 represents about a $55 million increase over the money spent in the 15-county area last year, officials said.
Major projects scheduled for this year include building new circuits, replacing underground cables, inspecting and replacing utility poles and trimming trees that interfere with power lines.
Met-Ed will also install automated and remote control devices designed to enhance its electrical system and reliability.
"The infrastructure projects we have completed in recent years resulted in our 2013 reliability numbers being among the best we have ever reported," said Mike Doran, regional president of Met-Ed. "Whether it's installing equipment that can be operated remotely, or spending on tree trimming, our ultimate goal is to continue to enhance the reliability of our system to benefit our customers."
Met-Ed serves approximately 550,000 customers spread across a 3,500-square-mile service area.
