The 115,000 volt Tri-State transmission line coming from Ogallala feeding our Arthur and Hyannis substations lost to structures between Arthur and Hyannis last night. Tri-State is working on this problem. Tri-State was able to re-energize to north of Arthur which allowed Arthur Substation to come online but still left Hyannis Substation off.


We at PREMA attempted to backfeed Hyannis from Lakeside but the line would not hold. We are patrolling this subtransmission line by ground and by air to determine the amount of damage. We know of at least two poles on the ground.


We also tried to feed the Hyannis area from Arthur but discovered we have at least 25 poles on the ground which kept us from doing so.


The Lakeside substation has two circuits with problems and we are patrolling these circuits to look for for them.


If you see any downed lines please stay away from them and call PREMA at 762-1311. We appreciate your patience!
