“…Over subhourly to hourly time scales, wind variability is a concern for voltage and frequency regulation 18 and the capacity for the grid to manage rapid changes in supply 19 particularly in conditions where renewable energy production is high and demand is low, due to the low system inertia provided by wind turbines and solar photovoltaic cells 20 . This may lead to increased curtailment of wind farm output in future as the proportion of variable renewable energy sources in the grid increases 21 .…”

The growing reliance on intermittent sources of renewable energy poses challenges for developing reliable electricity networks. This study has analysed the spatial and temporal characteristics of the UK's offshore wind energy production based on reanalysis of offshore wind speeds between 2000–2017, considering both the 2019 and future distribution of offshore wind farm capacity in UK waters. The extent and frequency of low wind power events are assessed, which are shown to vary seasonally. The correlation in output from offshore wind farm pairs reduces with increasing distance between them, albeit at a slower rate than has been observed for onshore wind farms. The conditional probability between regions of low energy production is also evaluated, which reveals that regions such as the English Channel are much more susceptible to simultaneous periods of low wind energy production if there is limited wind energy production in south‐west England or in the North Sea. Nevertheless, aggregating energy production from all offshore wind farms has a positive effect in reducing the likelihood of prolonged periods of country‐wide very low energy production. Comments are made on the possibilities for regional distribution of installed capacity to reduce the overall variability of wind energy and the relevance of these findings to electricity networks with increasing penetration of wind‐generated electricity.

“…25 In other countries such as the UK the curtailment percentage is expected to reach almost 4.8%. 26 In Italy and Spain, as well as in many other countries, the curtailment share is laying low, around or even below 2%. However, in a number of western countries where electricity grids are already mature, it is observed that the more the renewables share increase in the energy mix, the higher the curtailment level is.…”

The present study discusses alternative ways of achieving optimum energy efficiency for historic buildings in areas where sustainable energy projects are planned. About 25% of Europe’s building stock was constructed before the mid-20th century and despite EU’s strenuous efforts for the protection and conservation of historic buildings and complexes, achieving energy efficiency with the minimum or preferably no intervention remains as a requirement. The settlement of Monemvasia, has been selected as our case study. A model building was chosen, its special characteristics are presented, and four solutions to the energy efficiency upgrade of the building were tested: (a) the application of internal insulation, (b) a heat pump installation, (c) the application of roof insulation, and (d) the replacement of the internal doorframes. The four scenarios were simulated via the TEE-KENAK software and the percentage of the annual energy saved through the application of each one of the mentioned measures was estimated. The results proved that installing a heat pump and internal insulation would maximise energy savings. Coupling the energy demand of the settlement in correlation with a wind energy project in the wider area, and the available curtailment was explored. The results showed that if 300 houses decide on acquiring their electricity consumption from the local wind independent power producer, at a price of EUR 35/MWh, the possible profit from the market could reach EUR100,000 per year. Such a business-driven concept could be extrapolated and evolve into a holistic wind energy and historic environment symbiosis setting.

“…In general, the periods of low load and high wind availability are the most problematic scenarios [32,33]. However, the Sardinia island is managed covering the load with traditional synchronous generators, while all the wind produced power is exported to the continent through the two HVDCs, which represent the highest contribution in the regulating energy of the island.…”
