Rainbow Energy Center, LLC is a North Dakota‑based electric power generation company that owns Coal Creek Station, a large power plant in the region. The company took ownership of Coal Creek Station on May 1, 2022, following an acquisition from Great River Energy; at that time, Nexus Line, LLC also acquired the HVDC transmission line, with both entities affiliated with Rainbow Energy Marketing Corporation. The Coal Creek Station is a major local employer, supporting a sizable workforce in the community. The company operates within the electric power sector and is pursuing expansion of its assets and infrastructure through partnerships. In 2025, Rainbow Energy Center announced a strategic partnership with Intensity Infrastructure Partners to develop a natural gas pipeline to bring Bakken gas to eastern North Dakota, signaling ongoing diversification of energy assets beyond the power plant. The base address in Bismarck, North Dakota reflects its primary location, and its corporate structure includes affiliates that manage generation and transmission assets.
