“North Dakota’s largest coal-fired power plant was recently approved by the McLean County Commission for re-zoning of 800 acres of agricultural land to commercial near Rainbow Energy Center’s 1,151 MW Coal Creek Station.”
This approval would pave the way for Rainbow Energy’s Coal Creek to power new AI data centers. “Rainbow Energy has previously said its plans for the area include construction of new data centers that would source power from Coal Creek.”

Will the integrated circuit (IC) chip manufacturers be able to maintain AI’s ever-increasing demand for new data center facilities?
London Economics produced a report stating that, “AI demand forecasts have alarmed utilities that are rushing to add energy resources, despite concerns over impacts on power bills. Projected data center demand from the U.S. power market would require 90% of global chip supply through 2030, where such a scenario is unrealistic.”

Since aluminum conductor steel reinforced (ACSR) technology took over nearly all of power utilities’ transmission lines and overhead distribution lines, there has not been many advancements in newer and more feasible power delivery conductors. The ACSR technology has been around for over a century, but a new conductor technology is shaping up as an optimal replacement.
“AECC (Aluminum Encapsulated Carbon Core) technology represents a natural evolution that combines advanced conductor performance with traditional conductor safety and reliability. The design uses a pre-tensioned carbon fiber core protected by a seamless aluminum encapsulation layer, paired with annealed aluminum trapezoidal outer strands.”
“Advanced conductor technologies are gaining acceptance with utilities and grid operators. Reconductoring with advanced conductors can put a huge dent in the transmission capacity shortage”
Copper prices for all imported copper into the U.S. are expected to rise as much as 50% or more due to the threat of new tariffs that are expected to begin as early as August 2025.
The electric power and electronics industries will be impacted the most with paying nearly double for copper related materials needed for new construction, new assembly, power grid improvements, maintenance replacements, and necessary repairs.

Over the last several months, artificial intelligence (AI) has gained increasing popularity and remains dependent upon large server farms for processing AI’s big data requirement, at essentially, the speed of light. Planned new construction for enormous data centers are emerging nearly in every large city across the nation.
With America’s goal of becoming the “global leader in the AI race,” power utilities at both the generation and power delivery levels, struggle to maintain AI’s swift and vast desire for power. New electric generating plants and power delivery system upgrades remain behind the challenge while presenting a new dilemma: a more vulnerable electric grid with predictive power interruptions, brownouts, and potential blackouts.
