India to achieve 76% of renewable energy target by 2022: Wood Mackenzie

Wood Mackenzie's solar analyst Rishab Shrestha said India faces a myriad of challenges in the renewables industry.

India may achieve about 76 per cent of the target of having 175 gigawatts of renewable power generation capacity by the scheduled date of 2022 as it faces myriad challenges, Wood Mackenzie said Monday. India is targeting 100 GW of solar capacity and 75 GW of wind power by 2022.

"Even with significant cost declines, Wood Mackenzie expects about 76 per cent of the target to be met by 2022 and this would still be a noteworthy achievement," the world's leading research and consultancy firm said in a report.

Wood Mackenzie's solar analyst Rishab Shrestha said India faces a myriad of challenges in the renewables industry.

"The recent cancellation of auctions risks jeopardising investor confidence. Various duties on equipment and the associated uncertainty has led to a short-term uptick in solar prices. This leads to the knock-on effect on already cash-strapped state distribution companies who are showing an unwillingness to green light high priced solar projects," he said.

Nonetheless, the government's commitment and support towards renewables remain strong.

The government has been swift and adaptable at responding to various industry hurdles and are helping reduce project risks. As a result, renewable prices continue to remain competitive. Wood Mackenzie said combined wind and solar capacity have almost doubled from 2014 levels to 61 GW this year.

"Driving this growth is the significant cost decline that auctions continue to deliver," Shrestha said. "In the next five years, capital costs are expected to decline by 23 per cent for wind and 31 per cent for solar. This trend will only continue as new generation technologies replace old ones."

Wood Mackenzie expected non-hydro renewables to make up 13 for per cent of power generation mix by 2023.

Wind energy in South Africa

Join Brenda Martin, CEO of South African Wind Energy Association, and Steve Sawyer, Senior Policy Advisor at Global Wind Energy Council, for our ‘Doing Business In … South Africa’ webcast on Tuesday 9 October at 15h CEST.

Wind energy in South Africa

South Africa’s competitive tender process (Renewable Energy Independent Power Producer Procurement Programme (REI4P)) was launched by the Department of Energy (DoE) to facilitate private sector investment into grid-connected renewable energy (RE) supply. Since 2011, Independent Power Producers (IPPs) have been invited to submit bids for onshore wind, solar PV, concentrated solar power (CSP), small hydro, biomass, biogas or landfill gas projects.

Between 2011 and 2015 four such rounds of competitive bidding, referred to as bid windows (BWs), have been completed. Bid tariffs have fallen sharply over the course of the programme and the most recently awarded projects are amongst the lowest priced grid-connected RE projects in the world.

To date, over 6 000 MW of renewable power has been procured from 112 independent power producers through 7 competitive bid rounds in South Africa. Wind makes up 52% of procured capacity, with a total investment value of R74.7 billion, and has established a track record as the best value for money utility-scale renewable power option.

Following a 2-year hiatus in private procurement, the REI4P has been resumed since April 2018, and the country’s new President has confirmed a renewed commitment to growing domestic investment. Given that the country is now behind on its renewable energy investment targets, SAWEA is lobbying for the next procurement bid round to be announced in 2019.

In conversation with Steve Sawyer, Brenda will discuss the current context, opportunities and challenges faced by companies wishing to set up and sustain their wind-related business in South Africa. Steve will provide an update on global markets.

World’s biggest wind energy event kicks off in Hamburg

GERMANY: The Federal Network Agency (BNA) has launched its second joint tender for 200MW of wind power and solar PV.

wind-solar tender launched

A price ceiling of €87.50/MWh has been set in the auction, which will be concluded on 2 November.

The two technologies will compete directly against one another for the lowest cost of electricity, the agency confirmed.

In Germany’s first joint tender, carried out in April, the entire 200MW capacity was allocated to solar PV projects, with contracts awarded with values ranging between €39.60/MWh and €57.60/MWh.

Both solar and wind projects must be at least 750kW, according to auction rules.

Most solar projects are capped at 10MW, but may be 20MW in "some districts", the BNA stated, while no such limit is mentioned for onshore wind farms. Federal Immission Control approvals must have been issued for wind projects three weeks before the bid date (11 October). All participants must also factor in the cost of network and system integration into their bids.

Germany’s Renewable Energy Act (EEG) requires two joint onshore wind and solar auctions per year between 2018 and 2021.

This pilot phase will then be evaluated before the government decides whether to continue with the joint tenders beyond 2021. The heads of the Federal Solar Industry Association (BSW-Solar) and the German Wind Energy Association (BWE) described the joint tender process as "unsuitable" for encouraging the build-out of the two technologies, following the auction in April.

UK Wind Sector Defends Placid Summer Performance

Press decries “dirty summer” despite higher-than-ever installed wind capacity.

UK Wind Sector performance

The U.K.’s wind industry is cautiously responding to data showing poor project performance during a balmy summer.
Luke Clark, head of external affairs at the wind industry body RenewableUK, said his organization is awaiting official second-quarter energy figures, due out Sept. 27, before declaring an official position on news articles published last month.

The Guardian, for example, reported that calm, sunny weather had seen wind’s share of summer electricity generation dropping to 10.4 percent from 12.9 percent a year ago, forcing gas turbines to step into the breach. “This year has seen a comparatively dirty summer for power generation, due to the weather’s impact on renewables,” said the paper. “The wind drought meant that at times turbine blades sat idle for days.”

But despite an increase in carbon emissions compared to 2017, this summer was still the second greenest on record for the U.K. electricity system, according to the paper. In August an energy consultancy called EnAppSys claimed fossil-fuel generation had fallen to its lowest single-month level ever since World War II. Because of this, Clark said: “It’s important to look at wind performance over a meaningful period of time, rather than focusing on shorter spells.” In the first quarter of the year, he said, wind power had generated 19.1 percent of the country’s electricity. Annually, it is expected to contribute half of the 30 percent of electricity supply that comes from renewables, he noted. Wind, above all, was the driving force that helped the U.K. repeatedly smash coal-free generation records earlier this year. It even had a hand in helping the U.K. get through a headline-grabbing series of cold snaps dubbed the "Beast from the East" in March.

Wind turbines: How much power can they provide?

Wind power is an important pillar in Germany's energy policy turnaround: According to the German government, the resource should cover 65 percent of German electricity needs by 2030, along with solar, hydropower and biomass. In a recent study, Dr. Christopher Jung and Dr. Dirk Schindler from the University of Freiburg show that it will be possible to cover 40 percent of the current electricity consumption with wind energy alone by the year 2030. The prerequisite is that the operators distribute the plants optimally on the German mainland. To estimate usable wind energy, the researchers have developed a new three-dimensional model. As a basis for their calculation, they used the number of new installations in 2017. If it remains constant until 2030, Germany can reach the calculated value. The team recently published its findings in the journal Energy Conversion and Management.

A fundamental idea of the researchers while developing the model was to increase the efficiency with which the wind power is used. The scientists show that in particular repowering -- i.e. the replacement of old, small plants with newer, larger ones -- enables enormous increases in yields of up to several hundred percent. As a result, the cost of generating electricity, which is created when the energy is converted into electricity, can be reduced significantly to a level comparable to that of brown coal. However, in order to meet the current expansion targets of the Federal Government, a significant portion of the 30,000 wind turbines must be renewed and 6,000 additional systems must be additionally installed.

Based on the researchers' model, the available wind resources can be determined for all common plant types. Also, the expansion target can be adjusted as desired. Using the model, scientists can develop and assess scenarios in which the plant density, the expansion strategy and the repowering intensity are varied. The model also allows for a balanced spatial distribution. "In principal, we can avoid a disproportionate concentration in certain regions," summarizes Jung. In addition, the algorithm takes into account that the number of new installations to be installed is kept as low as possible. "This would minimize disruptions in the landscape while taking the landscape and nature conservation into account," says Schindler.

Exploring the prospects for offshore wind energy in Norway

Global offshore conference


WindEurope was at the Offshore Northern Seas (ONS 2018) event in Stavanger this week to promote the future prospects of offshore wind power.

WindEurope CEO Giles Dickson presented the outlook for offshore wind in Europe. There is currently 17 GW of offshore wind power capacity in Europe – providing 1.5% of Europe’s electricity – Dickson explained. 2017 was a record year, with installed capacity expanding by 25% whilst prices continue to tumble and wind turbines grow ever more powerful.

There is a stable pipeline of offshore wind farm projects over the next four years, which will take Europe to 26 GW of offshore capacity by 2020. However, there is uncertainty in some countries post-2020 and the growth of offshore has been too concentrated in too few markets, Dickson explained. Germany and the UK installed 3 GW of the 3.1 GW offshore wind installed in Europe in 2017.

The event coincided with news from Equinor that it would be exploring the possibility of deploying floating offshore wind to power its oil and gas production platforms in Norway. The project would consist of 11 wind turbines based on Equinor’s floating offshore wind concept, Hywind. The 8 MW turbines would have a combined capacity of 88 MW, enough to meet about 35% of the annual power demand of the five platforms.

“This project is really interesting in two respects,” Dickson explained. “It’s going to be the first time that offshore wind powers oil and gas production facilities. This will offer significant CO2 emissions reduction potential. It also demonstrates that floating offshore wind is coming of age. Hywind Scotland has already proved a great success. Equinor is now looking to take this a step further in what will be the world’s largest floating offshore wind farm. Thanks to a pipeline of projects, we expect European floating offshore wind capacity to grow to 350 MW as soon as 2021”.

The news came on the back of a previous announcement by the Norwegian Minister of Petroleum and Energy, Terje Søviknes, that Norway is set to unveil two sites for floating offshore wind plants later this year.

How climate change influences wind power

Global climate change

Impacts of clime change map

Climate change poses a big challenge for wind energy production in Europe. This is the conclusion of a study carried out by researchers at Karlsruhe Institute of Technology (KIT) using spatially and temporally highly resolved climate models. The mean wind power production of the entire European continent will change only slightly by the end of the 21st century. However, stronger seasonal fluctuations and a more frequent occurrence of low wind phases are expected.

Electricity from renewable sources already contributes a major share to the European energy supply. In the course of the energy transition, the share of regenerative sources in the German energy mix will be further increased. Wind power has proved to be a promising renewable energy source. Still, since wind power production is strongly influenced by the prevailing weather and climate conditions, it is subject to both short-term fluctuations and climate change. Scientists of the Regional Climate and Weather Hazards group of KIT's Institute of Meteorology and Climate Research – Troposphere Research Division (IMK-TRO), together with researchers of the University of Cologne, analyzed regional climate projections to study future changes of wind speeds and wind energy potentials in Europe until the end of this century. The results are now published in the Journal of Geophysical Research: Atmospheres.

For their study, the researchers used a model ensemble of high spatial and temporal resolution, which is based on simulations of the European climate modeling project EURO-CORDEX (Coordinated Regional Climate Downscaling Experiment – European Domain). CORDEX is the regional contribution to the IPCC (Intergovernmental Panel on Climate Change). The spatial resolution is twelve kilometers, and the temporal resolution is three hours. This allows for a more precise quantification of wind power production on the regional scale. For the calculations, a typical wind power plant with a hub height of 100 m is assumed.

The analysis reveals that only small variations of mean wind power production are to be expected at the continental scale for Europe by the end of the 21st century. These variations should remain within the range of plus/minus 5%. "For some countries, however, much higher changes in the range of plus/minus 20% can be expected" says Professor Joaquim G. Pinto, who leads the "Regional Climate and Weather Hazards" group at IMK-TRO. "Moreover, these changes may be subject to strong seasonal fluctuations."

According to the study, an increased variability of wind power production on different time scales has to be expected for large parts of northern, central, and eastern Europe, from daily to annual time scales. Wind speeds optimal for power production are expected to occur somewhat less frequently over the sea areas. At the same time, more frequent low wind phases with wind speeds below 3 m per second are expected over continental Europe. This will further increase the volatility of wind power production.

According to the projections, climate change will affect wind power production in various areas in different ways. "In the Baltics and the Aegean, wind power production might profit from climate change," says Julia Mömken, who is a member of the "Regional Climate and Weather Hazards" group of IMK-TRO. "By contrast, negative impacts are expected for Germany, France, and the Iberian Peninsula." The projected changes imply big challenges for wind power production in Europe. However, appropriate countermeasures, such as an extended use of decentralized wind energy production and a more extensive and reliable European power distribution grid might reduce the impacts of climate change on wind power production.

Wind Turbines to See ‘Unprecedented’ Growth in Size and Capacity

Unprecedent growth wind power devices

Offshore turbine capacity will increase by orders of magnitude, according to a new report from MAKE Consulting.

Onshore wind turbine size and capacity is on track to continue increasing at a steady pace, while offshore equipment will grow in leaps and bounds in the coming years, according to a recent note from MAKE Consulting on the future of wind turbine technologies.

“It’s actually a gradual shift onshore because markets are moving from 3 to 4 [megawatts],” said MAKE technology consultant and lead author Shashi Barla. “However, offshore turbine sizes are much bigger.”

Offshore, 6-megawatt turbines are now giving way to 7 megawatts. But Barla said next-generation turbines will fall between 12 and 15 megawatts with rotors at 200 to 260 meters. “That’s an unprecedented size,” he said. GE has already announced its 12-megawatt Haliade-X. Top manufacturers like Siemens Gamesa and Vestas will likely follow.

At the same time, Barla said, “product lifecycles are getting shorter," with bigger machines coming into the market more quickly.

In the U.S. that means 2-megawatt and 3-megawatt machines will remain the norm in onshore projects up through 2020, each accounting for a quarter of new product introductions through 2022.

With the Production Tax Credit phasedown, manufacturers will move toward 4-megawatt turbines to improve project economics.

Wind Power Evolution AMER, EMEARC, APAC

At the same time, Barla said, “product lifecycles are getting shorter," with bigger machines coming into the market more quickly.

Europe’s market already favors slightly larger turbines because of land constraints. But the region will also experience the transition toward higher-megawatt turbines as incentives end and auctions for merchant market power-purchase agreements favor larger equipment with lower levelized costs of energy.

“You’re not competing with subsidies anymore,” said Barla.

Uptake of higher-capacity turbines will be more delayed in countries such as China and India in the APAC market. Barla said auctions this year in China will push it toward 3-megawatt turbines with large rotors, while India will transition in the next three to four years.

The APAC market will actually be the largest in capacity, with 186.1 gigawatts. But through the end of 2023, MAKE expects 2-megawatt turbines to dominate.

Europe altogether will have the greatest reliance on large turbines with 3-megawatt and 4-megawatt models making up nearly 100 percent of the market by the end of 2023.

MAKE forecasts that the EMEARC market, which includes Europe and its advanced wind market, will be the only location where 5-megawatt turbines have a noticeable impact, accounting for 38 percent of new products through 2022.

In the offshore segment, U.S. demand is picking up, but technology innovation in Europe will drive development in that market as well as in Asia and the Pacific. Europe's more mature market is seeing faster development of turbines that cross the 6- and 8-megawatt threshold — and even topping 10 megawatts past 2020.

“In the U.S. you can bypass this shift,” said Barla. “Whether it’s current offshore tech or future offshore tech, it’s primarily coming from the European market.”

Siemens Gamesa, Vestas, and GE will all continue to build 2-megawatt machines for use in the U.S. and India.

MAKE notes that Vestas will increase its production and expand its supply chain of 3-megawatt and 4-megawatt turbines in time with the longer PTC cycle in the U.S. and to get the edge on post-2020 growth.

In all regions, Barla said Siemens Gamesa, GE and Vestas “will be well positioned for future growth.”

Auctions and drive for lower LCOE drive unprecedented growth in wind turbines

Competition is forcing wind-turbine OEMs to intensify the pace of innovation to lower LCOE, according to the latest research from MAKE. To improve competitiveness in auctions across global markets, wind-turbine OEMs have accelerated the pace of new product introductions, often with larger rated turbines and longer rotors. OEMs will exploit design margins, optimize investments in the supply chain, and deliver lower LCOE for asset owners, finds MAKE.

Lower prices in big wind turbines

The researchers have found that the competitive landscape — namely the transition in many markets globally to auction systems — are resulting in shorter commercial life cycles of turbine platforms. As a result, OEM business plans and CAPEX investment must incorporate shorter platform and product lifecycle assumptions, with higher volumes offered in auctions to offset those investments.

Wind-turbine platform choices are dominated by regional demand profiles and wind resource conditions. China and India are dominated by 2.0-2.5MW turbine models with specific power ratings of 180-220 w/m2 due to ultra-low wind speed regimes.

First generation 4.XMW platforms are inching toward 5.XMW platforms with power uprates in generators, an increase in gearbox torque ranges, and control system optimizations. The 5.XMW turbines will feature rotor sizes of 160-175+m and towers taller than 180m.

Developers in major markets such as the U.S., historically dominated by high capacity factor turbines, are increasing their deployment of larger rated turbines. The trend will ramp up in the United States post-2020, when 4.XMW turbines see siting in multiple states.

Logistics and transportation are one of the crucial challenges deterring the adoption of larger rotors. The industry are expected to consider two parallel developments tracks for blades on next-generation platforms, one with conventional cost-effective single piece technology and the other with split blades for logistic constrained sites.

Ideol turbine still waiting for grid connection

Global Wind Energy

FRANCE: The country's first offshore wind turbine is still waiting to export power to the grid after a fault in the transmission connection.

A "technical problem" affecting the export cable from the SEM-REV test site, where the Floatgen floating platform was recently installed to much fanfare, was identified about two years ago, site owner Ecole Centrale de Nantes (ECN) has admitted.

Although the fault was first discovered in 2016, it took a long time to identify exactly where the problem was, a source close to the test site explained.

It eventually turned out to be a fault in the junction box between the 20km-long export cable, installed in 2012, and a 400m-long extension added in 2015 when the hub – to which up to three demonstrators can be connected – was also installed, the source added.

When the Floatgen demonstrator was installed at the site in May, Ideol announced that "the connection to the export cable and to the power grid will be scheduled in the very near future after a last series of tests."

According to ECN, however, the plan was always for the final connection to take place in the summer.

Once connected, Floatgen will undergo a series of tests at the SEM-REV site for a period of at least two years.

Renewable energy generated 104% of Portugal's electricity consumption in March

Global Wind Energy

Most of the energy came from wind and hydroelectric power

Portugal generated more renewable energy than it needed in March, for the first time in at least 40 years.

Energy from renewable sources made up 103.6 per cent of mainland electricity consumption last month, according to data from the country’s power grid operator REN, although fossil fuels were used to occasionally top up the electricity supply.

The second-highest level of 99.2 per cent was set in 2014.

A report by the Portuguese Renewable Energy Association and the sustainability group ZERO, said the achievement was an “example” of what the future holds for renewable energy.

“It is expected that by 2040 the production of renewable electricity will be able to guarantee, in a cost-effective way, the total annual electricity consumption of mainland Portugal,” it said.

“These data, besides indicating a historical milestone in the Portuguese electricity sector, demonstrate that renewable energy can be relied upon as a secure and viable source with which to completely meet the country’s electricity demands.”

Weather conditions in Portugal also helped production from renewable sources, as wet and windy weather meant output from hydroelectric dams and wind turbines was high.
