US Energy Department orders additional power resources for Western Electric Grid

The U.S. Department of Energy issued an emergency order on Sunday authorizing the grid operator serving parts of 17 states to deploy idle power sources in order to prevent heat wave blackouts. The?U.S.

The order instructed grid operator Southwest Power Pool (SPP) to dispatch generator units as necessary to maintain reliability in a territory home to more than 20 million people, spanning from North Dakota to Louisiana.

The DOE order was issued shortly after SPP warned of the likelihood that emergency conditions will persist during peak demand periods. This highlights the region's vulnerability due to power plant failures, declines in winds generation, and disruptions to imported electricity.

The order also authorized SPP's backup generation to be used as a final resort, before declaring an emergency alert of level three. This can?be a final step before a grid operator decides to rotate outages. DOE stated that it issued the order on SPP's behalf.

In a recent statement, U.S. Energy Secretary Chris Wright stated that the Trump administration was tapping into an abundance of backup generators to provide affordable, reliable and secured power for hardworking American businesses and families.

SPP has seen the risk of rotating blackouts increase over the last week. SPP's reserves were dwindling on Friday after a sudden drop in electricity imports from neighboring grids.

SPP prevented outages on that day by asking for voluntary conservation to maintain reserves. SPP is expecting the highest demand of the week in the western territory on Sunday night as temperatures reach above 90 degrees Fahrenheit.

SPP is usually a net electricity exporter?because it has a large base of wind-generated power. The heat last week meant that neighboring grids couldn't provide as much power to SPP due to the weather-driven demand.

SPP's West Region will remain in a conservative operation?advisory?until 1 August, which was released to raise awareness about?potential threats against the grid reliability.

SPP released a statement saying that "Our West will likely continue to experience advisories, and energy emergency alerts conditions during high demand periods,"
