Ashtabula Wind I & II Collector Substations
Otter Tail Power Company
Completion Date - November 2009
Contract to Date - Over $ 2 Million
Barnes County and Luverne, North Dakota

The Ashtabula wind farm is the largest wind farm in North Dakota and consists of 250 turbines.

Ashtabula I project consisted of the construction of the Barnes County Collector Substation including pier drilling, excavation, concrete, structural steel supports, high voltage accessories, aluminum bus duct, breakers, switches, arrestor, transformers and ground grid for the 131 turbines.

Ashtabula II is the 230/34.5 kV substation near Luverne, ND and consited of building an entrance road to the substation pad and building up the pad which occupies approximately 5 acres. Work on this project also consisted of pier drilling, excavation, concrete, structural steel supports, high voltage accessories, aluminum bus duct, breakers, switches, arrestor, transformers and ground grid for the 80 turbines.


 

Minnkota Power Cooperative, Inc.
Langdon Wind Energy Center
Hensel, ND Substation Expansion
Langdon, ND Substation Expansion
Contract to Date - Over $ 200,000


This project involved the construction of 2 - 115kV substations for the Langdon Wind Energy Center which consists of 106 turbines and a 35 mile long transmission line. The work included excavation, concrete, structural steel supports, high voltage accessories, aluminum bus duct, breakers, switches, arrestor, transformers and ground grid. The deep cylinder concrete supports were placed with the use of caissons, drill augers and displacement pumps due to the high water table and poor soil conditions.

 

Sugar Hills Substation
East Grand Forks, Minnesota
Contract to Date - Over $ 1 Million


Constructed a new 15,000 kVA, 69-12.47/7.2 kV substation to replace the existing water plant substation. The substation was built on marsh type soil with a high water table. The entire site had to be over-excavated three feet and suitable fill hauled in to accommodate construction. A relatively new slip forming method was used to pour 20’-35’ deep concrete piers. The concrete piers ranged from 2-4 feet in diameter and were placed concurrently with the displacement of the ground water.

“ICS’s professionalism and the skill and hard work of all those involved made for an enjoyable project that was completed on time and on budget. It was a pleasure working with you and hopefully, we can do it again.” Todd M. Forster, KBM
