“…Nevertheless, currently, ERA5 provides a resolution high enough for wind energy studies, and the authors have successfully used ERA5 for technical purposes, such as for the identification of defective anemometers at wind farms [43]. Additionally, the potential of ERA5 has already been stressed in recent publications with a myriad of applications, such as wind energy resource assessment, economical constraint, or wave-wind interactions in offshore wind farms [8,[44][45][46][47][48][49]. To summarize, ERA5 is widely accepted as a reliable source of data for wind energy assessment studies and was also used in this work.…”

Hywind-Scotland is a wind farm in Scotland that for many reasons is at the leading edge of technology and is located at a paradigmatic study area for offshore wind energy assessment. The objective of this paper is to compute the Capacity Factor ( C F ) changes and instantaneous power generation changes due to seasonal and hourly fluctuations in air density. For that reason, the novel ERA5 reanalysis is used as a source of temperature, pressure, and wind speed data. Seasonal results for winter show that C F values increase by 3% due to low temperatures and denser air, with economical profit consequences of tens of thousands (US$). Hourly results show variations of 7% in air density and of 26% in power generation via FAST simulations, emphasizing the need to include air density in short-term wind energy studying.

“…For the experimental studies, triangular lattice masts of guyed type were chosen, which have a height of about 100 m with side dimensions of 1.2 and 1.4 m, and located in the vicinity of existing ten-meter height masts of meteorological stations. According to the results, which are given in another study [12], these regions are promising for WPPs. Wind measurements at these sites were started on the following dates: Ventspils -21.12.2017, Pavilosta -11.01.2018, Ainazi -21.01.2018. and scheduled to last at least till the end of 2018.…”

Prior to the start of any Wind Power Park construction project, it is necessary to carefully assess available wind potential in the selected area. The cost of such investigative studies is considerable – even with a relatively small 70 m tall mast it reaches several tens of thousands of Euros. In order to reduce costs related to wind speed measurements it is suggested to use the existing cellular communication masts that are widely spread in Europe. The study presents a methodological approach and the results of wind speed and wind shear measurements performed with the use of lattice cellular communication masts at the height of up to 100 m. A CFD model of airflow around a cellular communication mast structure was created in order to explore the impact of mast structure on the quality of wind speed measurements. The paper presents the results of the CFD modelling in the form of contour maps depicting the severity of airflow disturbances around the mast. The study is based on experimental measurements conducted in 2018 in three coastal sites of Latvia. At each site wind speed and direction were measured at several heights along with air temperature, humidity and air pressure. The experimentally obtained data in combination with the analysis of modelled CFD results shows the possibility of using cellular communication masts for accurate measurements of wind speed. Overall, the study shows that the proposed approach to wind speed measurements can result in high quality data and reduced overall expenses.

“…The main gas grid net stretches throughout Latvia; if we combine possible power sources as wind distribution [20] and available major hydro-powerplants on the map (Fig. 2), we can estimate whether the additional transportation is necessary.…”

As EU is steadily moving in the direction of emission reduction, each country must develop plans to decarbonise the transport and energy sectors. In Latvia, transport sector is one of the biggest emission sources. The heating applications come next. Both require carbon containing fuels and a transfer to carbon neutral fuel is necessary; therefore, hydrogen may be the answer to achieve the overall EU targets. As Latvia has renewable energy sources, some production, storage and use of hydrogen are possible. Currently clear guidelines for Latvia have been investigated. The existing natural gas network may be used for two tasks: large-scale hydrogen transportation and decarbonisation of natural gas network. To open the natural gas networks for hydrogen, the first evaluations are made and a possible scenario for hydrogen implementation in network supplying consumers in the household sector is analysed to evaluate decarbonisation with an overarching goal of carbon neutrality.
