Pewaukee-based American Transmission Co. unveiled a 10-year plan to revamp Wisconsin’s electrical grid, featuring more than $3 billion in transmission system improvements.
“Future projects will address economic and public policy benefits, along with local and regional reliability,” said John Flynn, ATC’s executive vice president of strategic planning and project development.
The expenditures include $1.2 billion in improvements and additions to the transmission network, $1.1 billion in maintenance and $0.5 billion in regional projects, the costs of which will be shared across the Upper Midwest. Other capital projects will range from $0.2 billion to $0.8 billion.
The report also notes that as regional planning efforts evolve and become more sophisticated, the economic benefits of transmission improvements become more evident. Easing congestion and providing access to sources of lower cost energy will help keep electricity prices in check. ATC estimates that, over the past three years, 99 percent of the cost of its transmission projects will be offset by savings in energy prices over the life of the projects.
The 10-Year Assessment, available online at www.ATC10YearPlan.com, lists more than 70 projects across the ATC service area.
