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

RENEWABLE POWER

RENEWABLE POWER GENERATION COSTS 2019 In the rest of Asia, this figure rose 10%, from USD 1 488/kW to USD 1 630/kW, over the same two periods. Yet, it is not just a question of costs rising within countries/regions, but also of a slowdown in deployment in China, notably in 2019. Given China still has the lowest installed costs, any decline in that country’s share raises the weighted average. Thus, part of the growth in the global weighted average in recent years is due to the fact that in 2019, China accounted for 31% of new hydropower capacity additions, down from 48% in 2010. The full dataset of hydropower projects in the IRENA Renewable Cost Database for the years 2000 to 2019 suggests that the total installed costs of smaller projects spans a wider range than larger projects, but in terms of deployment, the weighted-average installed cost is not materially lower for large projects, except for sizes beyond around 700 MW. At the same time that total installed costs were trending upwards, so too were capacity factors. Between 2010 and 2013, the global weightedaverage capacity factor of newly commissioned hydropower projects rose from 44% to 50%, while between 2014 and 2019 it varied between 46% and 51%. In 2019, the global weighted-average capacity factor was 48%, one-tenth higher than in 2010. Hydropower is somewhat unique, in that depending on the site characteristics and the ability to store water behind the dam, a project can take a flexible approach to designing for different capacity factors. So for instance, systems can be designed with relatively high capacities relative to inflows, resulting in lower average capacity factors, but with the ability to generate large volumes when that is most valuable. Alternatively, generation could be more constant and result in higher capacity factors for a smaller electrical capacity. This diversity is evident in the data for the 5 th and 95 th percentiles of project-level capacity factors, which have ranged from around 23% to 71% for the last four years. In 2019, the global weighted-average LCOE of hydropower was USD 0.047/kWh – 6% higher than in 2018 and 27% higher than in 2010. The increase in LCOE since 2010 is lower than the 38% increase in global weighted-average total installed costs due to the moderating influence of O&M costs, as well as the one-tenth increase in average capacity factors. Despite the increase in global weighted-average LCOE since 2010, hydropower remains a competitive, low-cost source of the electricity, with its global weighted-average LCOE still comfortably below the cheapest fossil fuel-fired source of new electricity generation.

LATEST COST TRENDS Bioenergy Bioenergy for electricity generation offers a suite of options, spanning a wide range of feedstocks and technologies. Where low-cost feedstocks are available – such as by-products from agricultural or forestry processes onsite – they can provide highly competitive, dispatchable electricity. For bioenergy projects newly commissioned in 2019, the global weighted-average total installed cost was USD 2 141/kW (Figure 1.9). This represented an increase on the 2018 weighted-average of USD 1 693/kW, which is itself a revised figure, substantially lower than the USD 2 150/kW published in 2019. Due to the heterogeneity of bioenergy feedstock and technology costs – and the typically higher technology costs in OECD countries – annual global weighted-averages are strongly influenced by the technology mix and geographical location of where plants are commissioned. Outside the OECD countries, the combustion of sugar cane bagasse wood waste and other vegetal or agricultural wastes uses proven, low-cost technologies. As a result, non-OECD countries typically have lower average installed costs. For instance, the weighted-average total installed cost of bioenergy projects in the IRENA Renewable Cost Database is USD 1 578/kW for China and USD 1 368/kW for India, while it is USD 3 179/kW for Europe and USD 4 329/kW in North America. Capacity factors for bioenergy plants are very heterogeneous and are typically driven by the availability of low-cost feedstocks. Between 2010 and 2019, the global weighted-average capacity factor for bioenergy projects varied between a low of 64% in 2012 to a high of 86% in 2017. The widest variation in capacity factors is observed where feedstocks are agricultural or forestry wastes or residues, with the variation for bagasse being notable for ranging from 24% (5 th percentile of projects) to 89% (95 th percentile). With a greater share of projects commissioned in non-OECD countries utilizing waste streams, where availability is often low outside certain seasons, weighted-average capacity factors in Europe and North America (81% and 84% respectively) are higher than in China (64%), India (68%) and the rest of the world (66%). The wide range of bioenergy-fired power generation technologies, feedstock costs and their availability results in a broad range of observed LCOEs for bioenergy electricity generation projects.
