It reports service to approximately 17,012 customer accounts and generated about $0.05 billion in annual electric revenue, with a service footprint spanning 10 ZIP codes.

In 2023, the average City of Holyoke - (MA) customer experienced 105.4 minutes of power interruptions, the industry-standard SAIDI metric (System Average Interruption Duration Index).

Over the same period, SAIFI (outage events per customer) was 1.21, putting the typical customer at roughly 1 distinct interruption that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 105.4 minutes; the difference from the headline 105.4 shows how much of the outage total came from weather rather than everyday grid issues.
