95 miles of cable was trenched into the ground to carry electricity from each wind turbine to the collector substation. |
 |
The power generated by the 106 turbines flows into this new collector substation. A cement pad was built to hold the transformer that weighs 353,390 pounds. |
 |
The 115-kv circuit breaker shown here trips on and off to control the output of the entire substation. |
 |
The collector substation transformer steps up the voltage from 34.5-kv to 115-kv before it goes to the Langdon substation, then out to the grid. |
 |
A ten-mile section of 115-kilovolt transmission line was built to carry electricity from this collector substation to the Langdon 115-kv substation. It moves electricity from the wind center onto the regional transmission grid. |
