Ironwood’s work for SCE has been completed both on-time and under budget while never causing construction delays. The Red Bluff Substation supported many more biological resources and was constructed concurrently with another nearby substation. Even with a larger number of species and resource concerns, Ironwood’s compliance activities facilitated construction of the Red Bluff Substation with no delays due to biological resources. In contrast, the nearby substation experienced numerous delays and inactive equipment issues related to biological resource Issues.


  • Work completed both on-time and under budget
  • No construction delays due to biological resources
