Danish group developing in-tower battery solution

KK Wind Solutions, Vestas, PowerCon and Aalborg University claimed if their energy storage solution accounted for just 8% of a wind project’s capacity, it could eliminate nearly 90% of fluctuations in energy production.

The group aims to develop software algorithms to aid monitoring and control of the batteries installed at the base of towers.

Lithium-ion batteries are currently being considered for the project, KK Wind Solutions said.

While energy storage solutions to the inherent variability of power generated by wind turbines do exist, the group argues large-scale implementation is limited by high procurement and maintenance costs.

“The potential for a cost-effective energy storage solution in wind turbines is enormous,” KK Wind Solutions’ head of global research and development Kristoffer Qvist Nielsen said.

“With such technology, we will be able to make wind turbines an active and constant energy source, which will accelerate the competitiveness of wind energy to new heights.” 

The project started only recently and will run for three years, KK Wind Solutions added.

New England Offshore Wind Receives Mass Support

Researchers at the University of Massachusetts Amherst (UMass Amherst) have conducted a study showing that the large majority of the participants support offshore wind off the New England coast.

The research was divided into two studies, where the first included an online survey of 89 New England residents and the second included visitors and residents around the 30MW Block Island offshore wind farm.

In the first part of the study, 83 participants, representing 93%, said they support offshore wind off the coast of New England, with 6 participants saying they are against offshore wind. On the other hand, both groups significantly underestimated the level of support for offshore wind in New England. On average, participants estimated that roughly 53.8% of other New Englanders support offshore wind.

The second part of the study was conducted in the summer of 2016 during the construction of the Block Island offshore wind farm, but before the turbines were operational. It included 429 respondents, with 76% of them being visitors.

The results have demonstrated a high support for the wind project, since 72% of island visitors, 71.4% of residents, 82.9% of seasonal residents and 75.7% of Rhode Island residents supported it. However, respondents estimated that just 52% percent of Block Islanders and 61.8% of visitors would support it, a major gap between perceptions and actual levels of support.

Both studies provide evidence that members of the public inaccurately underestimate levels of support for offshore wind projects. Evidence of partial pluralistic ignorance is apparent among supporters: individuals supportive of the technology overestimated opposition to offshore wind, though as a group they did not perceive majority opposition. According to the researchers, among those few who are opposed to offshore wind projects, evidence of a false consensus effect was present. Opponents in both studies not only overestimated levels of opposition, they perceived that they held the majority opinion, the researchers said.

Ezra Markowitz, assistant professor in environmental conservation at UMass Amherst, said: “This severe underestimate of public support for this technology may be one factor that holds back wider adoption and implementation of projects in the United States. Our results highlight the importance of considering not only peoples’ own beliefs about new renewable energy technologies, but also their beliefs about others’ opinions.”

UK: Digitalisation – A Next-Level Opportunity Offshore Wind Should Take

Industrial digitalisation could enable significant opportunities for export growth in the UK offshore wind sector, according to the latest UK Made Smarter Review – previously known as the Industrial Digitalisation review. 

The review identifies opportunities for the UK offshore wind sector in industrial digitalisation, the existing barriers to digitalisation, and recommends actions that would accelerate the realisation of the opportunities that emerge from the adoption of digital technologies.

A big export opportunity, especially for UK consultancy companies, could come in the foundation design field with an advanced digital simulation at the engineering stage that could enhance UK content in offshore wind projects.

When it comes to active management of the grid using digital forecasting, the review says that it is already very sophisticated. Nevertheless, there are opportunities for innovations around available power estimation, localised wind prediction and market trend modelling (at high time granularity) amongst others, the report reads.

Also, strong export potential lies in big data techniques allied to more extensive use of sensor technologies that can reduce the cost of electricity by reducing operations and maintenance (O&M) costs. Furthermore, the use of specialised robotics in the maintenance of less accessible assets such as turbine blades has a long-term potential as robots can be used to carry out inspection work and, with time, this will extend to them undertaking actual maintenance such as injecting repair resins in wind turbine blades.

Barriers to digitalisation were identified in auction mechanisms, skills development, cross-sector cooperation, and innovation.

The review recommends developing a more coordinated approach to the development of industrial digitalisation in the offshore wind sector as the first thing on the list of actions to take.

FTI upgrades long-term forecast despite short-term blip

The market analytics and consultancy firm lowered its short-term installation forecast (2017-2021) to 287GW, which is 1.5% down compared with its Q1 predictions.

FTI said the downgrade was due to challenges in China — which faces a slowing installation rate over the rest of the decade, Germany, India, France, Poland and Turkey.

However, between 2022 and 2026, FTI predicts an annual average growth rate of roughly 3.3%, with installations increasing more rapidly at the end of the period.

Over the ten-year period overall, FTI suggests 625GW of new wind capacity will be installed, which is 1.1% higher than its prediction in Q1.

Asia Pacific will contribute 52.1% of the total in the next decade, with Europe (22%), North America (11.7%) and Latin America (7.3%) also contributing.

Fastest growing

In its H2 2017 global market update, FTI identified the 15 fastest-growing markets over the next ten years.

It found Russia was due to expand by 74.1% between 2017 and 2026 with 4GW of new capacity.

Algeria (63% growth), Kenya (54%), Israel (50%) and Iran (46%) were also identified as the biggest growth markets.

Manufacturers

In the first half of 2017, FTI’s provisional figures found Vestas was the largest manufacturer by order volume, taking a 23.4% market share, totalling 4.8GW of new orders.

The total did not include orders from the MHI Vestas offshore wind joint venture.

Vestas leads the other of the “big four” OEMS as Siemens Gamesa Renewable Energy (19.3%), GE (18.6%) and Goldwind (15.1%) in dominating the global market.

Innergex expands renewables portfolio with Alterra acquisition

The acquisition means Innergex expands its renewables portfolio beyond its traditional markets in France, the US and Canada and increases its capacity by more than 40%, the company said.

Alterra owns 364MW of operational projects with a combined capacity of 825MW — including half of the 204MW Shannon wind farm in Texas and 26% of the 144MW Dokie 1 site in British Columbia.

It also fully owns the 350MW Foard City site, which is said to be at an “advanced stage”, and has a majority stake in the 200MW Flat Top project — both of which are in Texas.

The developer also has interests in hydro projects in Canada and Iceland, solar projects in the United States and Icelandic geothermal projects.

Innergex, meanwhile, owns just over 1GW of installed capacity, spread across 52 operational power plants — mostly hydroelectric and wind projects.

All of its wind projects are in France and Canada, and include the 149.3MW Mesgi’g Ugju’s’n project in Quebec and the 210MW Nulki Hills site being built in British Columbia.

It also has stakes in prospective projects totalling 3.94GW, Innergex said.

Following the transaction, Innergex will have an overall net power generation capacity of over 1.6GW, including projects being built. It aims to have a net installed capacity of more than 2GW by 2020.

“The geographic and energy sources profile of Alterra’s portfolio further diversifies Innergex’s asset base by adding operating hydro and wind projects in Canada, a large number of operating, under construction and prospective wind projects in the US and operating geothermal assets in Iceland,” Innergex CEO Michel Letellier said. 

Ross Beaty, Alterra’s executive chairman, added: “The combined company will have a lower cost of capital, stronger balance sheet, more diversified asset base and greater capacity to grow rapidly and efficiently.”

The cash portion of the transaction is to be funded by a five-year C$150 million ($117 million) loan from Caisse de depot et placement du Québec, Innergex stated.

It also obtained commitments from two unspecified “leading Canadian banks” to shore up its credit facilities and upsize its revolving credit facility to C$700 million ($546 million) — up C$275 million ($214 million) from its principal amount.

The transaction is subject to approval by Alterra’s shareholders and “other customary closing conditions”, the companies stated.

Vattenfall Paints Norfolk Vanguard Picture

Vattenfall has issued a preliminary environmental information report revealing project details related to the 1.8GW Norfolk Vanguard offshore wind farm.

In the report, Vattenfall states that the wind farm will comprise two distinct areas, NV East and NV West, located in the southern North Sea, approximately 70km and 47km from the coast of Norfolk, respectively.

Norfolk Vanguard Ltd. is currently considering constructing the project in a single phase of 1800MW, in two phases of 900MW, or in three phases of 600MW.

As Offshore WIND reported earlier, the project would comprise between 90 and 257 wind turbines, each having a rated capacity of between 7MW and 20MW, with a total installed capacity of 1.8GW. The turbines would either all be located within NV West or across both NV East and NV West.

Due to the large size of the sites and the fact that the wind turbines may be installed in up to three phases, up to three different turbine models may be used, with each construction phase likely to use a different turbine model.

Additionally, there could be more than one type of foundation used for the project, which will be determined by a number of constraints, such as ground conditions, water depths, the turbine model used, wind conditions and market options. The preference is to consider foundation locations within water depths of 40m or less, but it may be necessary to build at locations with up to 50m of depth, Vattenfall said. The foundations would be manufactured onshore and most likely delivered to site as fully assembled units with all ancillary structures attached.

Norfolk Vanguard Ltd. is considering both a HVDC and a HVAC electrical solution for the offshore and onshore infrastructure for the project. There would me a maximum of three HVAC offshore substations, and a maximum of two HVDC solution platforms.

The report says that the maximum number of export cables is six, while the maximum length of the array cable is 514km. In addition, the maximum length of the interconnector cable is 100km.

The O&M facility, i.e. the service port, is yet to be chosen.

According to Vattenfall, the project’s lease period would last up to 50 years, while the indicative construction duration would be between 3 and 7 years.

Construction of the project under either approach is anticipated to commence between 2020 and 2021 for the onshore works and around 2022 for the offshore works.

The Swedish company launched the Norfolk Vanguard project in March 2016, and is planning to submit a planning application to the UK Planning Inspectorate in 2018, with hope to obtain an irrevocable consent in early 2020.

Keen on Project Flexibility and Next-Generation Solutions

Vattenfall announced that the detailed design work for the project will occur post-consent following financial close and procurement of contractors, materials and infrastructure.

The company said that the project design envelope must provide sufficient flexibility to enable Norfolk Vanguard Ltd. and its contractors to use the most up to date, efficient and cost effective methods and technology in order to enable the commercial success of the project. In addition, post-consent/pre-construction site investigation will further inform the detailed design.

Key aspects where Vattenfall eyes flexibility include wind turbines, HVAC/HVDC connection, build-out, and construction and maintenance methodologies.

The flexibility is required for turbine capacity and parameters due to the potential evolution of technology prior to construction of the wind farm.

Additionally, flexibility regarding built-out scenarios/phasing options is necessary so Norfolk Vanguard Ltd. is able to construct the offshore wind farm so it produces power to the National Grid as early as possible while maximising efficiencies during construction, and construction and maintenance methodologies should enable competitive procurement and the most cost effective option to be adopted.

Norfolk Vanguard Ltd. is considering both a HVDC and a HVAC electrical solution for the offshore and onshore infrastructure for the project. A decision on the final electrical solution for the project would be made post-consent during the final design stage of the project and it would be based on the best available technology, balanced with providing the best value for electricity consumers.

DONG Seeks Borssele Project Certification Services

DONG Energy has issued a call for tenders looking for certification bodies for the assessment of the site conditions at its Borssele 1 & 2 sites. The contracted party will evaluate whether a site conditions assessment has been carried out and documented adequately.

Under a 3-year contract, the contracted certification body will verify that the design basis is sufficient and adequately documented to ensure a safe design. It will also evaluate that the site-specific loads and load effects are derived in conformity with the design basis, including an independent load analysis.

Furthermore, the company awarded the tender will verify that the design of the support structures, including their bolted connection, complies with the applicable codes and standards, the design basis and the results of the ILA; and verify the interfaces between the Type Certificate, the ILA and the Support Structure Design Evaluation.

All assessments will be evaluated in compliance with the IEC 61400-22.

The deadline for submission of tenders is 27 November 2017.


DONG Energy won the concession rights to build Borssele 1 & 2 in July 2016. The project site is located 22km from the coast of the Dutch province of Zeeland. The wind farm will be built in water depths between 14 and 38 metres and will cover an area of 128.3km².

In July, DONG Energy and Siemens Gamesa signed an agreement for the supply and maintenance of 94 8MW turbines for the project, followed by signing of a grid connection agreement with TenneT.

The power supplied by the 752MW offshore wind farm will be sufficient to cover the annual electricity consumption of close to one million households.

Borssele 1 & 2 is scheduled for commissioning by the end of 2020.
