UGI Utilities, Inc is an investor-owned utility operating in Pennsylvania under EIA identifier 19390. It reports service to approximately 61,450 customer accounts and generated about $0.13 billion in annual electric revenue, with a service footprint spanning 31 ZIP codes. Because it is investor-owned, the state public utility commission oversees its rate cases and reliability performance rather than a local board.
In 2023, the average UGI Utilities, Inc customer experienced 119.0 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). That is comfortably under the 120–180 minute national benchmark range, a sign of solid grid resilience and quick outage response. SAIFI, the average number of outage events per customer, was 0.83 for the same period, so customers statistically faced roughly 1 distinct interruption that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 85.0 minutes; the difference from the headline 119.0 shows how much of the outage total came from weather rather than everyday grid issues.
With 4 consecutive years of EIA data (2020–2023), UGI Utilities, Inc's reliability record can be judged on trend rather than one isolated year. SAIDI climbed from 67.0 to 119.0 minutes over that window, a shift that can point to worsening weather exposure or delayed grid modernization.
