Power demand surges throughout PNW….it’s hot out there!!

BPA strengthens backbone of West Coast transmission

The Bonneville Power Administration’s electric power and transmission experts are working together to keep the electrons flowing to millions of Northwest consumers and businesses during the expected heat wave this week, which they anticipate will break BPA’s record for peak summertime electricity consumption.

The previous BPA summertime record was set on July 16, 2014. During that week, when the mercury soared, air conditioners and fans were humming and electricity peaked at 7,861 megawatts at 6 p.m. Compare that peak to a typical 80 degree summer afternoon when electricity consumption may be 600 MW less.

With the region yet again facing a potential multi-day summer heat wave above the 100-degree mark, BPA is preparing for extremes.

“As we take a number of steps BPA-wide to get ready, it’s also important to note that in the utility business, unforeseen issues can emerge at any time,” said Janet Herrin, BPA’s Chief Operating Officer. “The goal is to be as prepared as possible so if something does occur we can quickly restore delivery of power where needed to meet demand, whether from wholesale power generated at federal dams or power coming from other sources.”

One variable BPA’s experts are monitoring closely are the wildfires burning near electrical transmission corridors in multiple locations in the Northwest. Winds can intensify or shift in a matter of seconds, which drive the path of flames in any direction. In addition, excessive heat over multiple days places additional stress on all parts of the grid and can cause power lines to sag, sometimes by a factor of several feet, which is why BPA works hard to keep rights-of way beneath high voltage transmission lines clear of vegetation and debris.

BPA’s preparedness steps range from delaying certain maintenance activities that can be safely scheduled for another week to working with federal dam operators to ensure the water intakes for hydro turbines are free of debris and optimized for power generation. The agency has also stepped up its non-wires efforts. These are tools and processes that can be employed as an alternative to building transmission lines and can increase reliability during times of extreme weather and high power demand.
BPA has also reached out to its workforce throughout the Northwest to take the proper steps in staying hydrated and reducing heat exhaustion. “A stronger, healthier workforce has fewer safety incidents and also is better prepared to respond to unplanned events,” said Brad Bea, BPA’s chief safety officer.

At the conclusion of this summer heat event, BPA will share with the public whether or not a new summer peak was recorded.

BPA also encourages consumers who are interested in energy savings tips and heat wave preparations being made in their communities to plug into their local utility provider.
