Part 1

The purpose of preparing cost-benefit analyses in relation to measures for promoting efficiency in heating and cooling as referred to in Article 14(3) is to provide a decision base for qualified prioritisation of limited resources at society level. The cost-benefit analysis may either cover a project assessment or a group of projects for a broader local, regional or national assessment in order to establish the most cost-effective and beneficial heating or cooling option for a given geographical area for the purpose of heat planning. Cost-benefit analyses for the purposes of Article 14(3) shall include an economic analysis covering socio-economic and environmental factors. The cost-benefit analyses shall include the following steps and considerations: Establishing a system boundary and geographical boundary The scope of the cost-benefit analyses in question determines the relevant energy system. The geographical boundary shall cover a suitable well-defined geographical area, e.g. a given region or metropolitan area, to avoid selecting sub-optimised solutions on a project by project basis. Integrated approach to demand and supply options The cost-benefit analysis shall take into account all relevant supply resources available within the system and geographical boundary, using the data available, including waste heat from electricity generation and industrial installations and renewable energy, and the characteristics of, and trends in heat and cooling demand. Constructing a baseline The purpose of the baseline is to serve as a reference point, to which the alternative scenarios are evaluated. Identifying alternative scenarios All relevant alternatives to the baseline shall be considered. Scenarios that are not feasible due to technical reasons, financial reasons, national regulation or time constraints may be excluded at an early stage of the cost-benefit analysis if justified based on careful, explicit and well-documented considerations. Only high-efficiency cogeneration, efficient district heating and cooling or efficient individual heating and cooling supply options should be taken into account in the cost-benefit analysis as alternative scenarios compared to the baseline. Method for the calculation of cost-benefit surplus The total long-term costs and benefits of heat or cooling supply options shall be assessed and compared. The criterion for evaluation shall be the net present value (NPV) criterion. The time horizon shall be chosen such that all relevant costs and benefits of the scenarios are included. For example, for a gas-fired power plant an appropriate time horizon could be 25 years, for a district heating system, 30 years, or for heating equipment such as boilers 20 years. Calculation and forecast of prices and other assumptions for the economic analysis Member States shall provide assumptions, for the purpose of the cost-benefit analyses, on the prices of major input and output factors and the discount rate. The discount rate used in the economic analysis for the calculation of net present value shall be chosen according to European or national guidelines The national discount rate chosen for the purpose of economic analysis should take into account data provided by the European Central Bank. . Member States shall use national, European or international energy price development forecasts if appropriate in their national and/or regional/local context. The prices used in the economic analysis shall reflect the true socio economic costs and benefits and should include external costs, such as environmental and health effects, to the extent possible, i.e. when a market price exists or when it is already included in European or national regulation. Economic analysis: Inventory of effects The economic analyses shall take into account all relevant economic effects. Member States may assess and take into account in decision making costs and energy savings from the increased flexibility in energy supply and from a more optimal operation of the electricity networks, including avoided costs and savings from reduced infrastructure investment, in the analysed scenarios. The costs and benefits taken into account shall include at least the following: Benefits Value of output to the consumer (heat and electricity) External benefits such as environmental and health benefits, to the extent possible Costs Capital costs of plants and equipments Capital costs of the associated energy networks Variable and fixed operating costs Energy costs Environmental and health cost, to the extent possible Sensitivity analysis: A sensitivity analysis shall be included to assess the costs and benefits of a project or group of projects based on different energy prices, discount rates and other variable factors having a significant impact on the outcome of the calculations. The Member States shall designate the competent authorities responsible for carrying out the cost-benefit analyses under Article 14. Member States may require competent local, regional and national authorities or operators of individual installations to carry out the economic and financial analysis. They shall provide the detailed methodologies and assumptions in accordance with this Annex and establish and make public the procedures for the economic analysis.
