The world’s biggest offshore wind farm, Hornsea 2, generates first power

First power on Hornsea 2, which is located 89 km off the UK’s east coast, was achieved after its offshore substation (OSS), the world’s largest offshore AC substation, and reactive compensation station (RCS), were installed in late October 2021. Once Hornsea 2 is completed, power will be transferred from the 165 wind turbines via 373 km of array cables to the OSS and RCS, reaching the national grid via 390 km of offshore and 40 km of onshore export cables which terminate at the onshore substation in Killingholme. Hornsea 2’s 165 8 MW Siemens Gamesa wind turbines will be capable of generating 1.32 GW of clean electricity. Together, the two projects will be capable of providing enough power for well over 2.3 million homes.

Why Tamil Nadu’s old wind turbines are still awaiting replacement

While India has made significant progress in renewable energy capacity building, wind power has been largely neglected. The country must set short-term milestones to accelerate wind development in response to the climate emergency.

The state of Tamil Nadu has the highest installed wind capacity in India. It is home to 25 per cent of the nation’s wind power capacity.

Tamil Nadu has the oldest wind turbines, which date back to the 1990s. Due to their smaller hub heights (25-30 metres) and low capacities (<500 kilowatts), early machines are underutilised.

What’s the carbon footprint of a wind turbine?

Dear Sara,

Wind turbines are an absolute joke. Has anyone actually figured out the amount of carbon emissions emitted for the entire process from initial construction of the components and land development (construction machinery emissions)? — Mike M.

Hi Mike,

Thank you for this apparent attempt at a “gotcha” question, as it gives me the opportunity to reply with a resounding yes! People have studied, in detail, the amount of carbon pollution emitted during the life of a wind turbine.

In fact, this type of analysis constitutes an entire branch of research known as “life cycle assessment,” with its own handbooks, internationally agreed-upon standards,

The future of wind energy is floating turbines on the ocean

Floating turbines could be deployed in deeper waters further offshore. There, winds are stronger and more consistent. Fewer species of birds can be harmed by the spinning blades. The infrastructure would create fewer conflicts with fishermen and other users of the oceans. They can be out of sight from the shore. Currently, there are three types of floating wind energy structures that serve as a basis for how farms could be built. The only floating wind farm generating meaningful amounts of electricity is Hywind Scotland, developed by Equinor in 2017.

Adwen & LM Wind Power Unveil World’s Longest Wind Turbine Blade

Offshore wind turbine manufacturer Adwen and turbine rotor blades supplier LM Wind Power have unveiled the world’s longest wind turbine blade. The 88.4 meter wind turbine blade has been designed for Adwen’s AD 8-180 wind turbine, an 8 MW wind turbine with a 180 meter rotor diameter. The image shown above is of the very first of the wind turbine blades for this new design, manufactured at LM Wind Power’s factory in Lunderskov, Denmark. The new 8 MW wind turbine is a big step towards lowering the LCoE of offshore wind energy, with the LM 88.4 P blade being designed with manufacturability and reliability at the forefront of developers’ minds.

China Blows Past the U.S. in Wind Power

New data from Bloomberg New Energy Finance show China installed just under 29 gigawatts of new wind energy capacity in 2015, surpassing its previous record of roughly 21 GW set in 2014. The country also accounted for more than 46 percent of all wind power installed globally for the year, eclipsing the next largest market, the United States, which added 8.6 GW. After China and the United States, the world’s largest markets for new wind power in 2015 were Germany, India and Brazil, with gross installs of 3.7, 2.6 and 2.6 GW, respectively.

COVID-19 pandemic caused slowest growth of wind power in decade in India

India added just 1.1 gigawatt of onshore wind power projects in 2020, the lowest in a decade, according to a new report by BloombergNEF, an international energy research organisation. The report titled India’s Top Wind Suppliers in 2020 attributed the slow growth to the novel coronavirus disease (COVID-19) pandemic. The pandemic resulted in nation-wide lockdowns in 2020 and caused severe disruptions to the supply chain and movement of goods and people, delaying project execution, the report noted. India’s wind power capacity addition peaked in 2016-17, with about 5.5 GW of installations. Despite a target of 4 GW for 2017-18 and 2018-19 each, the installations were about 47 per cent and 37 per cent, respectively, of the target. The target for 2019-20 was reduced to 3 GW.

Kenya’s New Wind Farm Will Provide Nearly One Fifth Of The Country’s Power

Last week Kenyan President Uhuru Kenyatta broke ground on a major renewable energy project for the country and for the African continent as a whole: a 310-megawatt wind farm some 300 miles north of the capital city of Nairobi. The farm, which will consist of 365 turbines when fully completed in mid-2017, will be the largest in Africa — overpowering Morocco’s Tarfaya wind farm, currently Africa’s biggest project with 131 turbines. It is also expected to provide around 17 percent of Kenya’s power demand. Known as the Lake Turkana Wind Power project, the wind farm will be spread across 162 miles in a part of the country that receives steady wind all year.

Moving wind turbine blades toward recyclability

A new material for wind blades that can be recycled could transform the wind industry, rendering renewable energy more sustainable than ever before while lowering costs in the process. The use of a thermoplastic resin has been validated at the National Renewable Energy Laboratory (NREL). Researchers demonstrated the feasibility of thermoplastic resin by manufacturing a 9-meter-long wind turbine blade using this novel resin, which was developed by a Pennsylvania company called Arkema Inc. Researchers have now validated the structural integrity of a 13-meter-long thermoplastic composite blade, also manufactured at NREL. In addition to the recyclability aspect, thermoplastic resin can enable longer, lighter-weight, lower-cost blades with less energy and workerpower. The thermoplastic material absorbs more energy from loads on the blades due to the wind, which can reduce the wear and tear from these loads to the rest of the turbine system.
