Northern Indiana Public Service Co. completed its 345-kV Reynolds-Topeka transmission line project, which will enhance system reliability and increase access to wind and solar energy.

The 100-mile transmission line connects NIPSCO's Reynolds substation in Reynolds, Ind.; Burr Oak substation in Burr Oak, Ind.; and Hiple substation near Topeka, Ind., according to a June 29 news release.

The transmission line is one of the 17 priority multi-value projects identified by the Midcontinent ISO. Construction of the project started in mid-2016.

NIPSCO, a NiSource subsidiary, also recently completed another multi-value project, the 765-kV Greentown-Reynolds transmission line in Indiana. The utility and Pioneer Transmission LLC, a joint venture of Duke Energy Corp. and American Electric Power Co. Inc., jointly constructed the project.

The two transmission projects had a combined cost of approximately $600 million.
