Michael Taylor at IRENA has summarised its latest studies that show how the cost of renewables are set to continue declining dramatically through to 2030. We all know how those costs declined in the last ten years. Going forward, the weighted average cost of electricity in the G20 countries from offshore wind could fall by almost 50% by 2030 from 2019 levels, onshore wind by around 45%, utility-scale solar PV by up to 55% and concentrated solar … [Read more...]
Modelling total costs for Onshore Wind power plants: from site prep to grid connection
The costs of wind turbines is dropping. But that means all the other capital costs - site preparation, foundations, infrastructure, tower construction – will become a bigger part of the total. In the U.S. they currently account for around 30% of the capital expenditures needed to install a land-based wind plant. To keep those costs under control the National Renewable Energy Laboratory (NREL) has created a comprehensive open-source modelling … [Read more...]
German Onshore Wind hit by residential regulations: will new profit-share rules help?
5.3 GW of newly installed capacity in 2017, 2.4 GW in 2018, 0.5 GW in the first nine months of 2019. Germany’s onshore wind power expansion has seen a dramatic slump. That’s completely against the trend in total renewables growth which saw its share of gross power consumption reached a record of almost 43% in 2019, up 5% on the previous year. Clearly, onshore wind is facing obstacles the other technologies aren’t, and that is the rules around how … [Read more...]
