Earnings before interest and tax, or operating profit, were up at £1.5bn (2021: 1.3bn) with earnings per share up at 95.4p (2021: 78.4p). These results exclude revenue from its one third stake in [...]

By Julian Singer The British Energy Security Strategy issued by the government on 7 April set a new goal of 50GW of offshore wind, including 5GW of floating wind, by 2030. Many doubt whether this is feasible. There is currently 11GW operational with a further 2GW expected to come on line in 2022 from the [...]

By Barney Smith Monday 4 April saw the release of the seventeenth annual report by the Global World Energy Council (GWEC), which is the most widely used source of data on the wind energy sector for industry, governments and others. At the industry level, the report paints an impressive picture, showing that in 2021 total global capacity rose by [...]

By Julian Singer While most of us were enjoying a few days of sun in the middle of last week, the electricity grid controllers in Wokingham were sweating with anxiety. The same weather conditions that had brought the sun also brought very still conditions. Wind power output dropped to near zero, after been well below [...]

By Julian Singer GWEC India presented its annual report on the Indian wind market on 10 June 2021. India is ranked 4th in terms of world wind power capacity, with 39.2GW installed as of March 2021, all onshore. This, however, is far from the current goal of reaching 450GW of renewable energy capacity by 2030, [...]

By Julian Singer The UK’s drive to reach net zero emissions depends hugely on affordable offshore wind energy. In the most recent auction of Contacts for Difference (CfD) in September 2019 the strike prices of the successful bids were around £40 per megawatt-hour (MWh) of electricity, well below the government’s guideline price for wholesale electricity [...]

By Julian Singer The UK may have the largest offshore wind capacity in the world, but little of it is operated by UK companies. It is well known that most of the equipment and technology for wind farms comes from non-UK firms. What may be less well known is that, according to the Crown Estate, [...]
