Holders: Prof. Sekavčnik Mihael

Subject description

Prerequisites:

Enrolment in the study year, continuous study, active and continuous participation at the exercises, exam on theory and exercises.

Content (Syllabus outline):

Theory and analysis:

Thermoenergetic analysis: Chambadal, Curzon-Ahlborn, Bejan, thermoeconomics, pinch methods. Exergy analysis, economic analysis: NDT, NSV, ISD. Environmental impact analysis, carbon footprint EROI and LCA approach.

Energy efficiency and availability:

Of energy processes, machines and systems in thermal power plants and industrial energetics. Improving the availability and efficiency of power plants and combined heat and power systems. Operation and annual availability diagrams, internal energy consumption.

Production scheduling:

Central production: base -, mid – and peak-load. Distributed generation, cogeneration, the substitute object method. Production diagrams (chronological and ordered). Mechanisms for balancing the peak demand for electric power, heat, compressed air and natural gas. Determining the backup capacity of systems.

Cost analysis and investment profitability:

Reducing costs through thermoeconomic analysis. Internal energy consumption and specific costs. Energy cost price and price structure. Evaluating investments, investment programs. The environmental protection costs, the cost of removing carcinogenic emissions.

Energy, energy carrier and emission markets: International energy and energy carrier trade. Emission market, forms of emission and carbon credit trade. Qualified production and incentives. Costs of emission reduction, the costs of carbon sequestration.

Case studies:

Carbon credit trade. Economic feasibility of investments, fuel replacements. Examples of energy price formation for power plants and CHP plants. Investment concept and investment program.

Objectives and competences:

Goals:

The objective of this course is to teach the students in detail about the methods of energy management, adopted by the thermo- energetics profession in the field of industrial energy conversion and use. To be able to work sovereignly in the enterprise sector, the mechanical engineers with a degree in energetics must master in addition to the technical knowledge also some specific economic knowledge. The provision of this economic knowledge is the fundamental goal of this course.

Competences:

The subject matter of the Energy management course provides the students with the knowledge necessary to sovereignly and independently master their work related to investments and production in the field of energetics. The students will be able to propose solutions and face the challenges and requirements posed in the field of energy management by the economists, entrepreneurs, environmentalists and other experts of both technical and nontechnical background. The students will:

  • acquire the knowledge for the execution of investment programs and for the evaluation of investments in the energetics,
  • acquire the knowledge for the optimisation of energy conversion system operation,
  • will be capable of doing energy management in the industry,
  • will be able to influence the costs and the formation of the cost price for the produced energy,
  • will be able to improve the efficiency, reliability and availability of energy processes and systems,
  • will be able to operate on the emission, energy and energy carrier markets.

Intended learning outcomes:

Knowledge and understanding

The attained knowledge enables an optimal energy management in the given economic situation and better understanding of the market laws in the field of energy and energy carrier management. The course enables the students to integrate technical and economic knowledge when making decisions on projects, improvements and investments.

Usage

Integrating theory and practice in rational and economic energy use, process optimisation and solving environmental problems. This knowledge is indispensable to management who must make decisions on purchases and investments in this field.

Reflection

The knowledge acquired enables the students to integrate economic and technical rules, as well as to upgrade the knowledge from the other fields of engineering activity.

Transferrable skills – related to more than one course

Understanding the interdependencies between the energy demand, the laws of economy and environmental responsibility. A critical attitude to sustainable energy use and the environment. Shared use of technical and economic knowledge.
