Combined Heat and Power Plant Instalation at Oil and Gas Fields: Is It Cost-Effective?

The paper presents an economic feasibility analysis which is applied to assess the cost effectiveness of implementing a combined heat and power system at oil and gas fields. The applicability of the proposed approach is illustrated in a real case study of the Serbian energy system, i.e., at one of the oil/gas fields operated by Petroleum Industry of Serbia. The purpose of this paper is to present a generic methodological framework so as to investigate the economic benefit and to calculate the payback period at the plant’s installed capacity. The findings of the analysis demonstrate that the mode of operation with sale of electricity at feed- in tariff and supply of excess heat to third parties is the most cost-effective because of its shortest payback period of 2.81 years. This method helps rationalize energy consumption and mitigate environmental impact in terms of CO2 emissions on the grounds that it uses a resource, i.e., fossil fuel originating from oil production (associated- dissolved gas), which has not been utilized so far. The paper demonstrates that the methodological framework can provide important insights into the strategic long-term and challenging decisions to be made by investors and/or policy designers at a national and/or regional level, highlighting potential risks and providing the roadmap and appropriate price signals on critical energy projects under real market operating conditions.
