Last week I had the privledge of sitting down with former FERC Commissioner Allison Clements & Rob Gramlich who spoke urgently and persuasively about the need to think bigger, bolder, and innovatively about delivering a power system that meets the nation's strategic imperatives. These conversation inspired my latest, "The Past & Present of Strategic Transmission":
Amid prospects for strong electricity demand growth, a utility transmission planner evaluates the future of the power grid, writing, “Past experience . . . has proved beyond any doubt that the adoption of higher voltage, higher capacity transmission facilities, as they become technologically feasible, is the most effective approach to meet this need . . . such transmission facilities can be provided without economic penalty and will, in fact, contribute to the achievement of future economies, both in investment and in operation.” No, the year is not 2024. It’s 1969, and American Electric Power (AEP) is undertaking pioneering investment in a new network of high voltage 765-kilovolt (kV) transmission lines.
Political, economic, and technology cycles come and go, but the basic physics of the grid holds true. In the present day, December of 2024, the Midcontinent Independent System Operator (MISO) has just approved a $30 billion portfolio of transmission projects centered on a region-spanning 765-kV “backbone” transmission system. The system will stretch from the western reaches of MISO in Iowa, South Dakota, and Minnesota and integrate into the existing AEP 765 kV system farther east in Indiana and Ohio.
