Completion of the acquisition of the fourth geothermal project in USA
近日，开山集团股份有限公司全资子公司Open Mountain Energy, LLC的全资子公司Mayacma Geothermal, LLC（“公司”）与Bottle Rock Power, LLC（“卖方”，“交易”）分别签署并完成了资产购买协议和租赁协议，以采购常规地热井场并出租卖方在加利福尼亚州Lake县持有的地热资产和设施，包括 23 口现有的地热井。作为交易的一部分，公司还同意承担与该项目相关的责任并已签订协议，根据未来发电量支付特许权使用费。
Recently, Mayacma Geothermal LLC, the wholly-owned subsidiary of Open Mountain Energy, LLC, a wholly-owned subsidiary of Kaishan Group Co., Ltd (“the Company”), signed and closed an Asset Purchase Agreement and Lease Agreement separately with Bottle Rock Power, LLC (“the Seller” and the “Transaction”), to procure the conventional geothermal wellfield and lease the geothermal assets and facilities that the Seller holds in Lake County, California including 23 existing geothermal wells. As part of the Transaction, the Company has also agreed to assume liabilities associated with the project and has entered into an agreement to pay royalties based on future power generation.
对历史运营和资源状况的评估表明，随着新电厂（100% 空冷的蒸汽 ORC）的建设，利用开山的 ORC 发电设备，现有井场每年能可持续发电约 7.5 兆瓦（净）。该项目将使用风冷冷凝器，这将允许 100% 的冷凝蒸汽被重新注入，这将有助于保持储层的稳定性。
Evaluation of historical operations and resource conditions indicates that with construction of a new power plant (Steam ORC with 100% air-cooling) approximately 7.5 MW (Net) can be sustainably generated from the existing wellfield on an annual basis utilizing Kaishan’s ORC power generation equipment. The project will utilize air cooled condensers which will allow 100% of the condensed steam to be reinjected which will help maintain the stability of the reservoir.Bottle Rock工厂位于Geysers已知地热资源区内，Geysers是世界上最大的地热发电厂综合体，从 350 多口井中抽取蒸汽，并从附近的都会区重新注回处理过的污水。该项目位于加利福尼亚州旧金山以北约 72 英里（116 公里）处，于1985年2月开始商业运营，原计划为55兆瓦的项目。由于缺乏对系统的补给，整个Geysers的资源严重下降，使得电厂规模与可用蒸汽资源之间巨大的不匹配进而导致的运营挑战，该工厂自2015年4月1日起进入非运营状态。
The Bottle Rock plant is located within the Geysers Known Geothermal Resource Area, the world's largest complex of operating geothermal plants drawing steam from more than 350 wells, and reinjecting treated effluent from nearby metro areas. The project is located approximately 72 miles (116 km) north of San Francisco, California. The Bottle Rock plant began commercial operation in February 1985 as an originally planned 55-megawatt project. Because steam resources throughout the entire Geysers region declined severely over this time period due to lack of recharge to the system, operational challenges stemmed from the large mismatch between power plant size and available steam resource. The plant was placed into non-operational status effective April 1, 2015.
The redevelopment of the project will consist of installing a new steam-ORC power plant, and replacing the wet cooling towers with dry cooling, allowing ~ 100% reinjection of the steam condensate to the reservoir, supporting the longer-term sustainability of production from the existing wellfield.公司已对该项目制定了详细的项目进度和规划，在及时获得许可批准的情况下，期望的COD为2023年12月，目前也处于与潜在交易对手就长期 PPA 进行谈判的后期阶段。Mayacma Geothermal, LLC 估计该项目将也有资格获得新可再生能源投资税收抵免。
The Company has made detailed project schedule and planning of the Project, with target COD in December 2023 subject to receiving permitting approvals in a timely manner. It is also in the advanced stages of negotiating with a potential counterparty for a long-term PPA. Mayacma Geothermal LLC estimates that the Project will be eligible for the new renewable energy Investment Tax Credit as well.这将是公司在美国的第 4 个地热特许权（其他为 Whitegrass、Star Peak 和 Fish Lake），也是公司在加州第一个地热项目。环境敏感性和水资源保护是Geysers区域的重中之重，Bottle Rock工厂将就此向Geysers展示独特且可持续的发电厂设计。公司正在探索Geysers其他地方的进一步的发展机会。
This will be the Company’s 4th geothermal project in the US (the others being Whitegrass, Star Peak and Fish Lake) and the first geothermal project in California. The Bottle Rock plant will demonstrate a unique and sustainable power plant design for Geysers resources, where environmental sensitivity and conservation of water resources is paramount. The company is exploring further development opportunities elsewhere in the Geysers.
