Mississippi Power sets company record for reliability in 2014
System Average Interruption Duration Index, or SAIDI, is the average duration of an outage for each customer served. In 2014, Mississippi PowerÂ’s SAIDI result was 55.7 minutes, which was better than the companyÂ’s goal of 74 minutes.
System Average Interruption Frequency Index, or SAIFI, is the average number of interruptions that a customer would experience. In 2014, Mississippi PowerÂ’s SAIFI result was 0.798, which was better than the companyÂ’s goal of 1.04 outages per customer.
“Results like this do not happen by accident,” said Jeff Franklin, vice president of Customer Services Organization. “It takes a tremendous amount of hard work, total commitment to our customers and superior performance to achieve success like this.
Both results were better than the Southern Company average of 101.5 minutes for SAIDI and 1.069 outages per customer for SAIFI.
“Investments in system infrastructure like our self-healing network and Smart Grid technology have resulted in fewer and shorter service interruptions,” said Randall Pinkston, Distribution director. “But at the end of the day, it’s the commitment to our customers from the line personnel, engineers and operations personnel that drives these results.”
As part of the Department of EnergyÂ’s Smart Grid Investment Grant, Mississippi Power recently added automation and several self-healing networks to its Distribution system. The automated devices reduce the duration of some outages by allowing operators to isolate problems before field personnel have arrived on-site. The self-healing networks determine where a fault is located and isolate it without any human intervention.
“We work extremely hard to reduce both the number and length of service interruptions,” Pinkston said. “We maintain our system and equipment and aim every day to keep the lights on.”

VANCOUVER - Politicians in British Columbia aren't focused enough on phasing out fossil fuel industries, a new report says.
The report, authored by the left-leaning Canadian Centre for Policy Alternatives, says the province must move away from fossil fuel industries by mid-century in order to meet its climate targets, but adds that the B.C. government is ill prepared to transition to a green economy.
"We are totally moving in the wrong direction," said economist Marc Lee, one of the authors of the report, on The Early Edition Wednesday.
He said most of the emphasis of B.C. government policy has been on slowing reductions…
