About The Project

Reliable and Affordable Power for the Future


The construction of the Greentown-Reynolds project—an approximately 70-mile electric transmission line from Greentown to Reynolds, Indiana—is a joint project between Northern Indiana Public Service Company (NIPSCO) and Pioneer Transmission (a joint venture of Duke Energy and American Electric Power).

Electricity is a vital part of our life, and our major power lines work like a highway system to deliver that electricity. But our existing electrical system was constructed decades ago and is in need of some improvements to ensure the continuous and reliable delivery of power. The Greentown-Reynolds project will modernize and expand our energy delivery system and improve access to regional power supplies.

A MISO Required Project

The Greentown-Reynolds project is one of 17 priority projects required by the Midcontinent Independent System Operator (MISO). The MISO controls and operates the transmission grid for all or parts of 12 Midwest U.S. states, including Indiana, and the Canadian province of Manitoba. Studies conducted by the MISO determined that improvement projects such as Greentown-Reynolds are necessary to maintain the reliability of the transmission grid while meeting local energy and reliability needs.

Project Facts

  • New approximately 70-mile electric transmission line will connect Duke Energy’s Greentown substation (East of Kokomo, Indiana) to NIPSCO’s Reynolds substation (in Reynolds, Indiana)
  • 200 ft. wide right-of-way (ROW) will be needed for the project.
  • Typical steel lattice structure height of 135ft. with an average 1250ft. between structures.
  • 765kV lines carry more electricity with less land disturbance than any other type of transmission line.

Benefits to Customers and the Community

A number of direct benefits to customers and the local economy will be attributable to the Greentown-Reynolds Project, including:

  • Improved reliability of our overall electric delivery system.
  • Increased access to regional sources of power, which can lower electricity costs.
  • Increase new construction related jobs and purchasing of services, goods and materials in the project area, stimulating local economies.
