Abstract. The continuing transition to renewable energy will require more wind turbines to be installed and operated in many new locations on land as well as offshore. The need to have geographic diversity, as well as limited availability of land in historically "good" locations for wind energy, means that wind turbines will also need to be deployed in hilly or mountainous regions, often known as "complex terrain". These areas can also experience challenging weather and climate conditions and may experience instrument- and blade icing that can further impact their operation. This paper – a collaboration between several IEA Wind Tasks and research groups based in mountainous countries – sets out the research and development needed to improve the financial competitiveness and ease of integration of wind energy in hilly or mountainous regions and in regions subject to icing. The focus of the paper is on the interaction between the atmosphere, terrain, land cover, and wind turbines, and covers all stages of a project lifecycle. The key needs include collaborative research and development facilities, improved wind and weather models that can cope with mountainous terrain, frameworks for sharing data and a common, quantitative definition of site complexity.

Short summary
The transition to low carbon sources of energy means that wind turbines will need to be built in hilly or mountainous regions or in places affected by icing. These locations are often called "complex" and have historically been challenging to develop. This paper sets out the R&D needed to make it easier and cheaper to harness wind energy there. This includes collaborative R&D facilities, improved wind and weather models, frameworks for sharing data and a clear definition of site complexity.
