Renewable Power Generation Costs in 2019

Die aktuellste Studie der IRENA zeigt auf, dass über die Hälfte des aus EE-Anlagen generierten Stroms, zu geringeren Kosten generiert werden kann, als bspw. Strom aus den neuesten Kohlekraftwerken. © IRENA 2020, IRENA (2020), Renewable Power Generation Costs in 2019, International Renewable Energy Agency, Abu Dhabi. www.irena.org

LATEST COST TRENDS The growth in deployment of renewable power generation technologies continued in 2019, as costs continued to fall and renewable power generation increasingly became the default source of least-cost new power generation. Since the year 2000, renewable power generation capacity worldwide has increased 3.4-fold, from 754 gigawatts (GW) to 2 537 GW by the end of 2019 (IRENA, 2020a). In 2019, 176 GW of new renewable power generation was added, with solar photovoltaic (PV) capacity increasing by 97 GW, onshore wind power by 54 GW, hydropower by 12 GW, bioenergy by 6 GW and offshore wind by 5 GW. At the same time, geothermal capacity increased by just under 700 megawatts (MW) and concentrating solar power (CSP) by 600 MW. New capacity additions by renewables represented 72% of the net capacity expansion of all power generation sources in 2019. Indeed, renewables have consistently accounted for more than half of all new, net capacity additions since 2015, while accounting for 49% to 53% of the total during the period 2012-2014, inclusive (IRENA, 2020a). Since 2012, IRENAs cost analysis programme has been collecting and reporting the cost and performance data of renewable energy technologies. Having, transparent, up-to-date cost and performance data from a reliable source is vital, given the rapid growth in installed capacity of these technologies. The associated cost reductions mean that data from even one or two years ago can be significantly erroneous. Indeed, in the case of solar PV, in some markets, even data six months old can significantly overstate the costs. The key sources of data for the cost metrics contained in this report are the IRENA Renewable Cost and the IRENA Auctions and PPA databases. The IRENA Renewable Cost Database has grown to include project-level cost and performance data for over 17 000 projects, representing over 1 700 GW of capacity, either installed or in the pipeline for commissioning in the coming years. The IRENA Auctions and PPA Database contains data on 10 700 projects or programme results, where pricing data is not disclosed for individual winners, totalling around 496 GW of capacity. These databases contain significant overlap, which opens up the possibility of directly comparing projects; an area IRENA will explore in greater detail in future work. In recent years, IRENA has expanded the range of cost and performance metrics it tracks and regularly reports, from average onshore wind turbine sizes and rotor diameters by country, to detailed cost reduction breakdowns for utilityscale solar PV. Since 2018 (IRENA, 2018a), IRENA has been publishing detailed data not only on the levelised cost of electricity (LCOE) 1 at the project level, but also on the results of auctions and power purchase agreements (PPAs). 1 Note that “weighted-average LCOE” and “weighted-average cost of electricity” are used interchangeably in this report. 19
