Orsted A/S shares dropped to a six-year low after New York regulators rejected a cost adjustment for offshore wind farms, prompting investor fears about a further writedown for one of the company’s US projects. ...Orsted already warned of impairments of as much as 16 billion Danish kroner ($2.3 billion) to its US portfolio in August. The New York ruling deals another blow to the Sunrise Wind project, which was already being held up by supplier delays. The adjustments sought by Orsted, Equinor ASA and others would have burdened consumers with as much as $12 billion in added costs.
