345kV International Transmission Line – Orrington to Baileyville

To meet the reliability and economic needs for electric power that have developed in New England, Bangor Hydro Electric Company (BHE) is pursuing the construction of an 84-mile long, 345kV tie-line from Maine to Canada. This line will connect with another 64-mile section in New Brunswick, Canada to reach its final destination. SGC staff have been at the forefront of this project since its inception. They supported and managed the entire study process to secure New England regional approval. The high complexity of the project study was a function of the multiple and inter-Area electric systems involved as well as the marginal electrical system in the service area. SGC staff was instrumental in coordinating the design effort among all parties and submitting successful applications for reliability and economic support from NEPOOL and ISO-NE.
