In a move that some are calling a big step toward a future powered by clean energy, the MISO Board of Directors unanimously approved on July 25 the Tranche 1 Long Range Transmission Planning (LRTP) portfolio of new transmission projects.
The $10.3 billion investment includes 18 transmission projects in MISO’s Midwest Subregion. The grid operator found a benefit-to-cost ratio of at least 2.6, where benefits well exceed costs.
The portfolio of what MISO calls “least-regrets” projects will mean more than 2,000 miles of additional transmission lines will be built. The portfolio is the most complex transmission study efforts in the organization’s history, the grid operator said. Altogether, the new transmission will allow up to 53 GW of new generation capacity to connect to the transmission grid.
