World Energy Council 2013 Cost of Energy Technologies The World Energy Council (WEC) and Bloomberg New Energy Finance (BNEF) have partnered to produce a comprehensive comparative study of the costs of producing electricity from a wide range of conventional and non-conventional sources. The aim and the unique value prop- osition of the study is to provide reference costs based on real project data, focusing on the leading renewables and conventional technologies across a range of regions worldwide. This is a joint BNEF/WEC report prepared for presentation at the 22nd World Energy Congress in Daegu, Korea (Rep. of). The report covers utility-scale wind, solar PV and solar thermal, marine, biomass, hydro and geothermal. Costs of producing electricity vary significantly around the world and across different energy sources. Any quantitative report or study is as good as the data and other information used for its production. To ensure that this report stands out in the crowded market space of energy related studies, it was very important to have access to the best data available in WEC Member Committees and their member companies. For further work on this topic, stronger support of WEC membership in procuring the required data will be crucial. It could make this project a sustainable top class reference source serving the needs of the entire WEC community. This should be considered a pilot study for upcoming studies with BNEF. We expect that this report will contribute to encour- aging more utilities to participate in the next surveys by demonstrating that the benefits of having access to relevant cost information are much higher than the hypothetical risk of confidentiality. Finally, one technical remark on the Levelised Cost of Electricity (LCOE) values. LCOE demonstrate electricity generation costs only, and thus do not represent the total cost of electricity supply such as grid connection or balancing costs for integration of volatile and intermittent RES (wind, PV). Neither does it include the costs of required back-up capacity based on conventional thermal plants, occasional capacity shedding and other additional system costs. Technology coverage The study aims to reflect both the relevant cost ranges for producing electricity from each renewable energy technology as well as the key drivers of projects costs. These include the cost of financing as well as equipment, installation, operating and maintenance and fuel costs where applicable. Four cost metrics are presented for each technology (see Methodology) u Capital expenditure (CAPEX). This includes the total cost of developing and construct- ing a plant, excluding any grid-connection charges. u Operating expenditure (OPEX). This is the total annual operating expenditure from the first year of a project’s operation, given in per unit of installed capacity terms. u Capacity factor. Also referred to as load factor, this is the ratio of the net megawatt hours of electricity generated in a given year to the electricity that could have been generated at continuous full-power operation, or 8,760 full hours. u Levelised cost of electricity (LCOE): a USD/MWh value that represents the total lifecycle costs of costs of producing a MWh of power using a specific technology. Note that the analysis only covers projects greater than 1MW in capacity, as the econom- ics of smaller distributed generation – like rooftop PV for example – differ substantially from those of larger projects and the collection of high quality data becomes problematic.
