TeraWulf expands Kentucky data center power plan to 1 GW

TeraWulf has expanded its planned Kentucky data center power capacity to 1 gigawatt, doubling the scope of the project described in the source material.

The plan is tied to Kentucky Power's Muskie buildout, and the utility said substation construction would begin in 2027.

The arrangement also includes TeraWulf funding residential bill credits and financing costs related to Big Sandy for customers.

The source does not provide additional project detail beyond the power target, the substation timeline, and the customer cost items.

The information comes from Engineering News-Record, which reported the update on Oct. 6, 2026.

Why it matters for AEC

A 1 GW data center plan with utility infrastructure work already linked to a 2027 start is a material power-and-site milestone for Kentucky projects. The residential bill credits and Big Sandy financing costs also show how large-load arrangements can extend beyond the facility itself into utility customer charges.

What this signal may mean for staffing or delivery capacity

The scale of the Kentucky power buildout may create meaningful operational and technical workload for TeraWulf and the utility partners as substation work approaches in 2027. That warrants monitoring for delivery sequencing and infrastructure coordination, even though the source does not indicate a staffing shortage or any open roles.
