Grid Expansion and Reinforcement Portfolio (GERP)

In 2023 and 2024 BPA announced over 20 new transmission line and substation projects, totaling over $5 billion in estimated costs, which will help improve transmission capacity and reliability throughout the Northwest.

These expansion projects, previously referred to as Evolving Grid projects, have been rebranded to the Grid Expansion and Reinforcement Portfolio (GERP) to reflect the expanded scope and purpose of the work.
