Western Grid Integration Could Produce Significant Cost Savings, Environmental Benefits

Combining the electric grids operated by PacifiCorp and the California Independent System Operator (ISO) to create a regional power marketplace could reduce energy costs by billions of dollars and help states meet their environmental goals, including California’s 50 percent renewable energy mark, according to a study released today.

The study, commissioned by PacifiCorp and conducted by Energy and Environmental Economics (E3), finds that integrating the two largest high-voltage transmission grids in the West to create a regional ISO could produce between $3.4 billion and $9.1 billion in shared cost reductions in the first 20 years through better grid management and efficiencies gained by planning for the resource needs of a single, rather than multiple systems.

The study also projects that development of a regional ISO is likely to reduce greenhouse gas emissions through coordinated planning, reduced curtailment of renewable energy, and lower overall costs to build new renewable resources.
