• Amazon has signed a 20-year power purchase agreement with Constellation Energy to expand and improve Maryland’s sole nuclear plant, which is also the state’s largest source of clean energy, the companies announced Wednesday.Amazon 已签署一份为期20年的与 Constellation Energy 签订的购电协议，以扩建和改进马里兰州唯一的核电站，该电站也是该州最大的清洁能源来源。两家公司于周三宣布了这一消息。
• The tech giant and the energy producer said the agreement will allow for over $3 billion in Maryland infrastructure, including renovations at the 1,790-megawatt Calvert Cliffs Clean Energy Center. The deal will also enable around 190 MW of new generating capacity, expected to come online between 2030 and 2032.这家科技巨头和该能源生产商表示，该协议将推动在马里兰州进行总额超过30亿美元的基础设施建设，其中包括对 1,790兆瓦 Calvert Cliffs Clean Energy Center 的翻新。该交易还将新增约 190 MW 的发电容量，预计于 2030年至2032年间投入运营。
• Constellation — the largest producer of clean energy and largest nuclear energy company in the United States — said in the Sept. 30 release that the investment and revenue certainty from the PPA will allow it to relicense the nuclear plant for another two decades. The company said the extension will allow for the development of new clean energy power plants at the site and enhance Maryland’s supply of carbon-free energy.Constellation——美国最大的清洁能源生产商和最大的核能公司——在9月30日的新闻稿中表示，PPA 带来的投资和收入确定性将使其能够为该核电站再取得20年的运营许可。该公司表示，这一许可证延期将推动在该场址开发新的清洁能源发电厂，并加强马里兰州的无碳能源供应。

Through the agreement, Amazon will receive 690 MW of power from the nuclear plant, including the 190 MW uprate. 通过该协议，Amazon 将从该核电站获得 690 MW 电力，其中包括 190 MW 的功率提升。

The tech and e-commerce company has also entered a separate retail supply agreement with Constellation to support its operations in the 13-state PJM market, according to the release. PJM is the largest power grid operator in the U.S. and centrally dispatches generation and oversees the movement of wholesale electricity in all or parts of Delaware, Illinois, Indiana, Kentucky, Maryland, Michigan, New Jersey, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia and the District of Columbia.新闻稿称，这家科技与电子商务公司还与 Constellation 签订了另一项零售供应协议，以支持其在覆盖13个州的 PJM 市场中的运营。PJM 是美国最大的电网运营商，并在特拉华州、伊利诺伊州、印第安纳州、肯塔基州、马里兰州、密歇根州、新泽西州、北卡罗来纳州、俄亥俄州、宾夕法尼亚州、田纳西州、弗吉尼亚州、西弗吉尼亚州和哥伦比亚特区的全部或部分地区集中调度发电，监管批发电力的输送。

All the electricity generated by the Maryland nuclear plant will flow to the PJM regional grid as usual, Constellation said. The deal demonstrates “how large energy users can support investments in new, reliable generation while strengthening the broader electric system,” the energy company added.Constellation 表示，马里兰州核电厂发出的所有电力将像往常一样输入 PJM 区域电网。该能源公司补充称，该协议展示了“大型能源用户如何能够在支持投资可靠的新增发电容量的同时，强化更广泛的电力系统”。

The companies said the agreement will help Amazon manage its energy costs for facilities located in the region.两公司表示，该协议将帮助 Amazon 管理其位于该地区设施的能源成本。

"Amazon is committed to investing in carbon-free energy to strengthen the grid and benefit the communities where we operate," Kerry Person, Amazon Web Services vice president of global operations and data center delivery, said in the release. "This long-term agreement with Constellation sustains the continued operation and expansion of Maryland's largest source of carbon-free energy, supports hundreds of jobs, and brings significant new generation to the regional grid.”“Amazon 致力于投资无碳能源，以强化电网并惠及我们开展业务所在的社区，”Amazon Web Services 全球运营与数据中心交付副总裁 Kerry Person 在新闻稿中表示。“与 Constellation 的这项长期协议将维持马里兰州最大无碳能源来源的持续运营与扩建，支持数百个就业岗位，并为区域电网带来大量新增发电。”

The Calvert Cliffs plant generates roughly 80% of Maryland’s clean energy, producing enough electricity to power approximately 1.3 million homes, according to the release.据该新闻稿称，Calvert Cliffs 电厂的发电量约占马里兰州清洁能源的 80%，所产电力足以为约 130 万户家庭供电。

Constellation has recently inked deals with several companies that are increasingly turning to nuclear energy to power their operations and make progress on their sustainability goals.Constellation 最近已与多家公司达成协议；这些公司正越来越多地转向核能为其运营提供动力，并推进其可持续发展目标。

Earlier this year, retail giant Walmart entered a long-term PPA with Constellation that will provide the retailer with nuclear energy, environmental attributes and energy capacity to support its Illinois operations.今年早些时候，零售巨头Walmart 签订了一项长期 PPA，Constellation 将向该零售商提供核能、环境属性和能源容量，为其伊利诺伊州的业务提供支持。

That followed a separate nuclear PPA Constellation signed with Meta last year, which gives the social media and tech conglomerate access to zero emissions power for its AI goals, while helping keep an Illinois nuclear facility online. The agreement will give Meta 1,121 megawatts of nuclear energy beginning in June 2027.而在那之前，另有一项Constellation 与 Meta 签署的核能 PPA 已于去年达成，该协议让这家社交媒体与科技集团获得零排放电力以推进其 AI 目标，同时帮助伊利诺伊州的一座核设施继续运营。该协议将从 2027 年 6 月起向 Meta 提供 1,121 兆瓦核能。
