Case Study: San Diego Gas & Electric achieves cost savings, compliance, and customer service gains with Davey Resource Group Tree Growth Regulator program

San Diego Gas & Electric cuts annual pruning 80% with Davey

San Diego Gas & Electric faced the challenge of managing approximately 430,000 trees to maintain regulatory clearance around power lines, with a quarter requiring costly annual pruning. Davey Resource Group proposed a solution using Tree Growth Regulator (TGR) treatments to slow tree growth and extend pruning cycles.

The solution implemented by Davey began as a pilot in 2011 and expanded to a system-wide program by 2015, targeting fast-growing species like eucalyptus. The results showed an 80% success rate in reducing annual pruning, leading to six-figure cost savings over three years, improved compliance, and enhanced customer service. Davey's program successfully helped SDG&E meet its cost, compliance, and customer service goals.
