Construction Starts On Horns Rev 3, Denmark’s Largest Offshore Wind Farm

Construction work is set to begin on Denmark’s largest offshore wind farm, Horns Rev 3, in October. The project will kick off when Vattenfall installs the first of a total of 49 foundations in the North Sea. When the offshore wind farm is complete, it will provide enough power to satisfy the annual electricity consumption of 425,000 Danish households. It is the first time in five years that an offshore wind farm will be built in Denmark.

“Horns Rev 3 is the first of three offshore farms that Vattenfall will construct in Denmark in the coming years. These wind farms will, in the highest degree, contribute to our strategy to have a fossil-free energy production within one generation,” says Gunnar Groebler, head of Vattenfall´s Wind Business.

The foundations consist of 40-50-metre ‘monopiles’ made of steel, with a diameter of 6.5 metres. The monopiles are driven about 30 metres into the seabed and will support MHI Vestas‘ 8.3 MW wind turbines that are presently some of the world’s most powerful turbines.

At the beginning of October, the first four monopiles were loaded onto a special vessel, the Innovation, in the Netherlands and driven into the seabed. The next four monopiles will then be loaded in the Danish Esbjerg Harbour in mid-October. The construction work will take place in an 88 square kilometres area in the North Sea, at least 34 km off the west coast of the Danish Jutland Peninsula.

Before the construction could begin, seabed preparations had to be carried out, including a geological survey and a subsequent detonation of old naval mines. Due to noise concerns, a support vessel is being used to place an air bubble installation on the seabed around the construction site. The installation creates a sound-absorbing, double layer of air bubbles that protect marine mammals in the area.

In addition to Horns Rev 3, Vattenfall will construct the Danish Kriegers Flak and Vesterhav South and North wind farms in the years ahead.

Vattenfall is a Swedish, state-owned, energy company with more than 20,000 employees with operations in Sweden, Germany, the Netherlands, Denmark, UK and Finland. Vattenfall supports the transition to a renewable energy system and has the objective to become leading in sustainable energy production and thereby secure a reliable and cost-effective energy supply.

Wind: China Maintains Emerging Markets Top Spot Following 19.7GW Build Boom

Wind industry intelligence service A Word About Wind has launched its Emerging Markets Attractiveness Index report for 2018, which provides insight and analysis into the most attractive emerging markets for wind companies. The index, now in its second year, ranks the top 30 emerging markets that investors should consider when investing in wind in Europe, Africa, Asia and Latin America. The list considers factors including political and economic stability for investors, alongside the growth of electricity demand and potential for wind growth, in order to rank the countries by overall potential. As with last year’s report, China tops the list and the ongoing trade war with the US shows no sign of slowing China’s formidable growth.

Corporate Sourcing of Renewables Growing, Taking Place in 75 Countries

Companies in 75 countries actively sourced 465 terawatt hours (TWh) of renewable energy in 2017, an amount close to the overall electricity demand of France, according to the report from the International Renewable Energy Agency (IRENA). With the continued decline in the costs of renewables, the report suggests, corporate demand will continue to increase as companies seek to reduce electricity bills, hedge against future price spikes and address sustainability concerns.

Arsenal Unveil Battery Storage System: First Of Its Kind At A UK Football Club

Arsenal Football Club has unveiled a battery storage system (BSS) to store enough energy to run the 60,000 seater Emirates Stadium from kick-off to full time. It follows a unique collaboration with Pivot Power to install a 2MW/2.5MWh lithium ion BSS, with funds managed by Downing LLP. The project, the first of its kind in the UK, will also save club money as it works to support low-carbon plans. The BSS allows Arsenal to avoid peak power prices, buying electricity when it is cheap and storing it for use when prices are high. Typically, energy can cost three times more at peak times than overnight. The installation maintains Arsenal as the leader in sustainability in sport following its commitment to clean energy with Octopus Energy in 2016.

Battery Boom: Wind And Solar Can Generate Half Of Worldwide Electricity By 2050

Coal is to shrink to just 11% of global electricity generation by mid-century, from 38% now, as costs shift heavily in favour of wind, solar and batteries. Wind and solar are set to surge to almost “50 by 50” – 50% of world generation by 2050 due to reductions in cost. “Cheap battery storage means that it becomes increasingly possible to finesse the delivery of electricity from wind and solar so that these technologies can help meet demand even when the wind isn’t blowing and the sun isn’t shining. The result will be renewables eating up more and more of the existing market for coal, gas and nuclear.”

India: Improved Monsoon Winds Help Power Producers in 2018 

After a prolonged period of decline, wind speeds in India during the 2018 monsoon season were significantly higher than normal; and up to 20% higher than long-term averages in some regions. These higher wind speeds benefit wind farm production; welcome news for wind energy operators and investors, who have faced several years of lower-than-normal wind energy production during the monsoon period. These increased wind speeds can thus counter recent patterns of decline contributing to an increase in investor confidence with a data-driven approach.
