n this episode of "Powering Canada Strong" we talk with retired professional engineer, Randy Stubbings, a man with 45 years of experience in the Alberta electricity industry about what 'line losses' mean. This refers to the fact that as electricity flows down a power line, there is 'resistance' that gradually reduces the amount of power that will be received at the other end of the line. Stubbings discusses, in brief, the difference between and Direct Current (DC) line, which is typically associated with power generated by renewables like wind and solar, or is used for long distance transmission, versus Alternating Current (AC), which is what our grid operates on. Converting power from DC to AC also incurs losses of power, plus many other factors affect line losses.
