The Southwest Power Pool Inc.'s (SPP) board of directors has approved a near-term transmission expansion plan that it says will result in the construction of $251 million in new transmission projects needed to maintain reliable supplies of electricity across its nine-state region. These projects are expected to be constructed over the next five years.

The board also approved a 10-year transmission expansion plan, with projects estimated at about $1.5 billion of engineering and construction costs that are expected to provide $834 million in net regional savings over 40 years, according to SPP.

The approved suite of projects are a result of SPP's integrated transmission planning (ITP) process, which is an iterative three-year cycle that includes 20-year, 10-year and near-term assessments, and targets transmission expansion solutions that meet reliability, policy and economic needs within the region.

The project portfolio from the ITP 10-year assessment is expected to mitigate more than 61 reliability issues, enable every state within SPP territory to meet its renewable energy goals or targets while reducing carbon-dioxide emissions, and provide regional energy savings that allow utilities to supply their customers' needs more economically.

The plan calls for 786 miles of 345 kV lines, 124 miles of 230 kV lines and 15 transformers.

"A well-planned, robust transmission grid gives us the flexibility to move energy from diverse generating resources to where it's needed across the region and beyond," says Lanny Nickell, SPP's vice president of engineering. "Adding more lanes to the transmission highway will improve our ability to provide the least-cost power to consumers and strengthen grid reliability so power is always there when we need it."
