PGE Customer Actions Resulted in the Largest Electricity Demand-shift in Company History During Multi-day Heat Wave Small energy conservation efforts added up to big results Portland General Electric (PGE) customers worked together this week to reduce energy use during Portland’s first heat wave of the summer. Coupled with PGE’s ongoing system upgrades and preparedness efforts, customers’ collective energy conservation actions supported reliable power delivery and grid stability during a time of extremely high power demand. Customer actions this week reduced electricity demand by nearly 109 megawatts (MW) during peak demand hours on Monday, July 8, and 100 MW on Tuesday, July 9; that is enough electricity to power over 90,000 homes for a four-hour period. Participation in PGE’s energy shifting programs, avoiding running large appliances during evening hours, and energy conservation efforts like adjusting the air conditioner by a few degrees or making energy-saving upgrades to their homes all added up to the significant energy-demand reduction. PGE has several voluntary energy shifting program options for customers and the company typically employs one or two at a time, as needed throughout the year. On Monday and Tuesday, PGE activated its entire portfolio of energy shifting programs, which approximately 200,000 customers participate in, to help alleviate strain on the grid due to record-breaking hot weather. This is only the second time in company history that PGE has called upon all the programs for multiple, consecutive days; the first time was during last August’s heat wave.
