A new grid capacity map is giving customers a first look at local distribution capacity in AEP Ohio territory, but the Ohio Manufacturers’ Association (OMA) says the development should be viewed as a starting point, not the finish line. The hosting capacity map shows where parts of the distribution system may be able to accommodate new electric load or distributed generation without requiring upgrades. The tool follows language included in House Bill 15, which the OMA supported to require better grid transparency and give customers more information about where electric infrastructure is ready for growth.
Distribution maps are useful, but they are only part of the picture. For major expansions, large-load projects and long-term economic development, transmission capacity is often the bigger question. OMA says the Public Utilities Commission of Ohio should build on this requirement and move quickly to ensure similar transparency for the transmission system.
“This is a useful first step, but it should not be mistaken for the finish line,” said Lindsey Short, managing director of energy and advocacy services for OMA. “The lesson here is not that utilities deserve applause. It is that customers get better information when the law requires it. Ohio needs transparency across the grid, especially on transmission capacity, which is often the bigger question for major manufacturing investments and long-term growth.” 6/1/2026
