AK SB105

Creates the Railbelt Electrical Transmission Authority as a division of the Regulatory Commission of Alaska to manage the electric transmission system in the Railbelt area and optimize electrical generation output to meet system load at the lowest possible cost.

Establishes a 13-member board appointed by the commission consisting of six utility representatives (one from each designated region), at least one independent power producer representative, at least one consumer representative each from Interior and coastal areas, at least one renewable energy sector representative, and at least one Alaska Energy Authority employee.

Authority may adopt rules governing a unified transmission system, establishing transparent tariffs, implementing open access nondiscriminatory transmission services, setting reliability and interconnection standards, and authorizing transmission projects, subject to nine or more affirmative votes and commission approval.

Prohibits the authority from owning assets exceeding $100,000 and requires the commission to provide staff support for the authority.

Exempts utilities with board representatives on the authority from certain Regulatory Commission of Alaska provisions that have been explicitly superseded by authority provisions.
