MD HB928

Expands certificate of public convenience and necessity (CPCN) requirements to apply to all transmission lines exceeding 69,000 volts, not just overhead transmission lines

Requires the Public Service Commission to consider cost impacts on ratepayers and environmental effects when determining whether to grant good cause waivers for construction on existing transmission lines

Repeals the automatic waiver provision that previously exempted construction on existing overhead transmission lines from CPCN requirements when no new property acquisition or larger structures were needed

Allows emergency construction on existing transmission lines without prior approval only when necessary to avoid imminent safety hazards or reliability risks, with a report due within 30 days

Requires the Public Service Commission to adopt regulations by July 1, 2027 establishing specific criteria for good cause waiver determinations; takes effect October 1, 2026
