气电联动机制下油气企业投资燃气电厂项目策略研究

Research on investment strategy of gas-fired power plant project by oil and gas enterprises under gas-electric linkage mechanism

近年来国际局势动荡,天然气价格高企,导致燃气发电成本上升。对此,中国主要省份出台气电价格联动机制,力求平抑天然气发电企业风险。江苏省采取天然气发电上网的两部制电价政策,气电价格存在联动机制。浙江省天然气发电存量机组继续执行两部制电价,电量电价按气电价格联动方式制定。油气公司依托丰富的上游资源,在燃气电厂领域具有天然资源优势,纷纷参与燃气电厂投资建设;与此同时,燃气发电板块作为终端用气设施,将天然气产业链进一步正向延伸,为产业链气量销纳、整体效益、协调发展等做出重要贡献。基于此,本文深入研究了各省份“气电联动”机制,并结合现金流量法分析了“气电联动”机制对燃气电厂项目收益影响,针对研究成果提出油气企业投资、运营燃气电厂的建议,从“气电联动”角度为投资主体项目决策、项目布局、资源配比提供思路与参考。

In recent years,the high price of natural gas due to the volatile international situation has led to a cost increase of the gas-fired power generation.In response,major provinces in China have introduced gas-to-electricity price linkages in an effort to mitigate risks for gas-fired power producers.Jiangsu Province has adopted a two-part tarif policy for natural gas-fred power generation,with a gas-to-power price linkage mechanism in place.Zhejiang Province continues to implement a twopart tariff for natural gas-fired power generation units,with electricity prices set according to the gas-electricity price linkage.Relying on rich upstream resources,oil and gas companies have natural resource advantages in the feld of gas power plants,have participated in the investment and construction of gas power plants,and the gas power generation segment as the terminal gas facilities,have further expanded the natural gas industry chain positively and made the important contribution for the gas sales industry chain,overall efficiency,and coordination of the development at the same time.For this reason,it thoroughly researches the mechanism of"gas-electricity linkage"in each province,and analyzes the impact of"gas-electricity linkage"mechanism on the income of gas power plant projects by combining with the cash flow method,and puts forward the suggestions of oil and gas enterprises to invest in and operate the gas power plants in light of the research results to provide ideas and references for the decision-making,project layout,and resource allocation of the investment entities from the perspective of"gas-electricity linkage".
