美国最大的大坝拆除项目的设计仍在继续,但联邦监管机构将其晋升为退役阶段的发展陷入困境,这些监管机构现在对投资者拥有的公用事业所有者之后将对成本超支或其他不可预见的问题表示关注。将结构移交给非营利组织。

联邦能源监管委员会于7月16日拒绝转移加利福尼亚州的克拉马斯水力发电项目的运营许可,并将俄勒冈州从公用事业太平洋地区转移到克拉马斯河更新公司,created in 2016under a settlement agreement to oversee the removal of four dams on the river.

根据协议,PacifiCorp成本消除the dams was capped at $200 million while the state of California would pay $250 million. The non-profit KRRC in March submitted to FERC a guaranteed maximum price of $446 million, which includes a contingency of $50 million, based on 60% design.

将其限制给Pacificorp的成本可以保护其客户免受删除大坝的未知风险,该方法得到了各州的公共服务公司的批准。一位公司发言人告诉ENR,FERC决定将Pacificorp掌握许可证的决定使其客户陷入困境,以解决成本超支和其他不可预见的问题。新利luck

“We are not walking away from the settlement. There could be a way to make this work,” says Bob Gravely, regional business manager for the utility. A meeting is set by July 24 for parties to the 2016 agreement, including officials of California, Oregon, tribal nations, local governments and others.

该组织说,KRRC将于2021年开始撤离大坝,但时机取决于聚会如何使FERC的裁决与和解协议的条款调和。卡鲁克部落主席罗素·阿特伯里(Russell Attebery)在一份声明中说:“我们知道,我们需要重新定居政党并根据需要进行调整以反映Pacificorp的目标。”“我们仍然致力于克拉马斯大坝的去除。”

FERC说,当事各方同意的财务和技术安排可能足以完成大坝的去除,但是与该项目相关的不确定性很大。

该18luck.cub机构说:“成本可能会升级超出预期和意外的技术问题。”他指出,KRRC的财务状况有限,没有水力发电坝运营或大坝去除的经验,并且可能面临无法处理的问题。

PacifiCorp has resources and experience, FERC said. “We believe that the public interest requires that PacifiCorp remain a co-licensee,” the agency said.

根据设计建造合同于2019年4月签名with KRRC, Kiewit Infrastructure West was selected to remove four hydroelectric dams, which will allow the river to flow freely with fish passage restored

Resource Environmental Solutions LLC was added in July 2019 as project restoration designer and McMillen Jacobs was selected in February as program manager.

The dams—J.C. Boyle in Oregon and Copco I, Copco II and Iron Gate in California—were built between 1918 and 1962 and have an aggregate hydroelectric capacity of 43 MW. Three dams on the upper Klamath River in Oregon will remain operating. The Klamath dams produce a total of 169 MW, PacifiCorp said.
