NE LB1259

Establishes a framework for "large-load customers" (100+ megawatt demand) to receive electric service from public power utilities or alternative "large-scale generation providers" that register with the Nebraska Power Review Board

Requires large-load customers to pay all incremental costs for service, including generation resources, distribution upgrades, transmission improvements, and infrastructure, ensuring existing ratepayers are not burdened by costs of serving large customers

Creates two pathways for large-load service: "connected generation systems" that link to public utility transmission, and "closed private generation systems" that operate independently from public utility infrastructure

Allows large-load customers to contract with alternative generation providers if the public utility fails to complete an evaluation within 6 months or cannot reach contract terms within 90 days of evaluation

Directs the Nebraska Power Review Board to approve large-load contracts within 60 days, adopt transmission cost allocation rules by January 1, 2027, and conduct triennial reviews of the act beginning in 2029
