在美國完成第四個地熱項目的收購
Completion of the acquisition of the fourth geothermal project in USA
近日，開山集團股份有限公司全資子公司Open Mountain Energy, LLC的全資子公司Mayacma Geothermal, LLC（“公司”）與Bottle Rock Power, LLC（“賣方”，“交易”）分別簽署并完成了資產購買協議和租賃協議，以采購常規地熱井場并出租賣方在加利福尼亞州Lake縣持有的地熱資產和設施，包括 23 口現有的地熱井。作為交易的一部分，公司還同意承擔與該項目相關的責任并已簽訂協議，根據未來發電量支付特許權使用費。
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.
對歷史運營和資源狀況的評估表明，隨著新電廠（100% 空冷的蒸汽 ORC）的建設，利用開山的 ORC 發電設備，現有井場每年能可持續發電約 7.5 兆瓦（凈）。該項目將使用風冷冷凝器，這將允許 100% 的冷凝蒸汽被重新注入，這將有助于保持儲層的穩定性。
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工廠位于Geysers已知地熱資源區內，Geysers是世界上最大的地熱發電廠綜合體，從 350 多口井中抽取蒸汽，并從附近的都會區重新注回處理過的污水。該項目位于加利福尼亞州舊金山以北約 72 英里（116 公里）處，于1985年2月開始商業運營，原計劃為55兆瓦的項目。由于缺乏對系統的補給，整個Geysers的資源嚴重下降，使得電廠規模與可用蒸汽資源之間巨大的不匹配進而導致的運營挑戰，該工廠自2015年4月1日起進入非運營狀態。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.
公司已對該項目制定了詳細的項目進度和規劃，在及時獲得許可批準的情況下，期望的COD為2023年12月，目前也處于與潛在交易對手就長期 PPA 進行談判的后期階段。Mayacma Geothermal, LLC 估計該項目將也有資格獲得新可再生能源投資稅收抵免。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.
這將是公司在美國的第 4 個地熱特許權（其他為 Whitegrass、Star Peak 和 Fish Lake），也是公司在加州第一個地熱項目。環境敏感性和水資源保護是Geysers區域的重中之重，Bottle Rock工廠將就此向Geysers展示獨特且可持續的發電廠設計。公司正在探索Geysers其他地方的進一步的發展機會。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.
