RED BLUFF, Calif. - PG & E is taking to the skies to inspect its vast network of natural gas transmission pipelines, partnering with PJ Helicopters to conduct aerial surveys aimed at saving time, cutting costs and improving safety. PG & E has more than 50,000 miles of gas transmission pipelines across the country, but some sections can be difficult and dangerous to access from the ground. The utility is now using helicopters and drones equipped with technology originally developed for missions to Mars to inspect hard-to-reach areas. PJ Helicopters, based in Red Bluff, is conducting the aerial surveys using lidar sensors from Bridger Photonics to check pipelines for leaks. The effort is expected to save PG & E $1 million this year and reduce surveying time from months to weeks. "With this new operating model and really this partnership with PJ Helicopters and also Bridger Photonics, which is the sensor, if that helicopter has to go down for maintenance, whether it's hundred hour, two hundred hour, four hundred hour maintenance, then they literally bring in a fresh helicopter, we swap out the sensor, and we lose no time," Scott Farrell, PG & E Leak Survey Program Manager said. PG & E is now using 20 helicopters as part of the program. The LiDAR sensors use lasers that can detect methane leaks and the height they are at. "So we're able to then say exactly where the leak is...
