The wind swept across the Great Plains early Wednesday, and electricity customers across the region benefited from it again.

The Southwest Power announced Friday on Twitter that it met its load requirement on the regional transmission grid it operates using a record 73.67% of energy generated by renewable resources at 2:14 a.m. on Oct. 9.

The grid had a load for needed energy of about 22.5 gigawatts at the time, and renewable sources in play, consisting of mostly wind with some hydro-generation, supplied about 16.5 gigawatts of that, officials said.

Wednesday’s record is just the latest in a string of wind and renewable milestones observed by the grid operator during the past decade.
