Around 400-500 customers remain without power in the Western Plains following the storm that left a path of destruction in its wake yesterday.

Essential Energy says its crews worked in "challenging conditions" last night and returned this morning to continue repair and clean-up efforts.

A spokesperson for the company said customers will receive texts with an estimate for when the power comes back on when it becomes available.

"At the height of the storms, more than 17,000 Essential Energy customers were without power in the southern, central and northern regions of New South Wales. At one stage, over 13,000 of those impacted were in Wagga Wagga and the surrounding areas," the spokesperson said.

"As at 11.30am today, the number of customers without power has been reduced to around 2,300 after crews made significant progress restoring power where it was safe and possible to do so."

According to the latest update from Essential Energy, 47 customers in the Collerina area near Bourke can expect the power back on by 10pm tonight.
