The latest data released by the Global Wind Energy Council (GWEC) shows North, Central and South America has installed 11.9 GW capacity of wind power in 2018, an increase of 12% on last year. In North America (Canada and USA) new capacity additions grew by 10.8% compared to 2017. In Latin America new capacity additions grew by 18.7% compared to 2017.

Looking at data from 2018, the Americas, with a total installed wind capacity of 135 GW, make up about 25% of the total new global installed capacity in 2018. The leading countries in the region include: USA, Brazil, and Mexico.

In North America, the recent and final extension of the Production Tax Credit (PTC) has driven volume. In Latin America, the commitment to auctions has continued to deliver volume for the region. The Latin America region is expected to continue its growth with a further expansion of the supply chain during 2019.

The North American wind market is one of the most mature and competitive in the wind industry. Many learnings and experiences from the success here can be used in other markets. The rise of corporate procurement during 2018 demonstrates how corporate sourcing can drive demand and volume in other wind markets. According to data from CanWEA and AWEA in North America the wind industry supports now over 160,000 jobs.

Brazil installed 2 GW of added capacity during 2018 and auctioned further capacity at world beating prices of as low as $22/MWh. Mexico installed almost 1 GW of new capacity, the highest capacity additions ever and now has a total capacity of 5 GW. Mexico expects to reach its target of generating 35% of its power capacity through renewables before 2024.

The development of the wind market in Latin America is very positive too. Large scale auctions have again taken place in Brazil, and GWEC expects the first auction in Colombia to be executed this month. Further investments in the supply chain by the leading OEMs Vestas and Nordex in Argentina prove the long-term potential of the market.

The North American offshore wind market continues to develop with supply chain planning taking place, tenders for offshore leasing zones being conducted (Massachusetts), JV formations (EDF and Shell for New Jersey leasing zones) and industry players establishing offices (MHI Vestas). GWEC expects projects to commence construction between 2020 and 2025.

The surge for wind in the Americas is expected to continue with GWEC forecasting over 60 GW new capacity between 2019 to 2023.

GoodWe simply can’t get enough! Having the quality requirements of a large spectrum of installers and end-users as a source of inspiration, GoodWe is pleased to introduce at the start of this new year of 2019, the totally brand new XS residential inverter.

The XS is an ultra-small single-MPPT, single-phase residential inverter that is even lighter and more compact than GoodWe’s NS inverter, saving installation space and easing the whole commissioning process. GoodWe has unbelievably miniaturized the XS inverter to have the size of an A4 paper, illustrating again the company´s leading cutting-edge technology. The XS weighs only 5.2kgs, making it also one of the most compact residential inverters available in the market.

Cannot emphasize enough the significant logistical advantages and the lower associated costs, which light weight and compact size of the XS represents more inverters can be loaded into pallets, reducing the cost of shipping it to destination from origin, at both international and domestic shipping levels. For installers, this is a blessing as with the XS they can significantly increase efficiency and profitability. And for users, handling the XS is something as simple as just putting it on a suitcase and taking it home.

It is available in 0.7kW, 1kW, 1.5kW and 2kWs. This represents also a wider range of options than GoodWe’s NS inverter, whose lower power range was of only 1kW. The XS broader scope of options and the fact that its lower power is as low as 0.7kW, makes this inverter a very suitable option for mini residential systems in which only two or three solar panels are installed, especially large social housing projects. The user of this kind of PV system won’t need to consider anymore installing two expensive micro-inverters because now the XS can do a better job at a lower cost.

Something noteworthy on the XS is that its small size is not a contradiction and does not compromise its technological muscles. The XS is mini but it still offers 30% of DC input oversizing, significantly enhancing the potential of the installations in which it is used. Likewise, by making use of sophisticated and patented topology developed by GoodWe, the XS does not jeopardize efficiency, delivering as much as 97.5% of European efficiency.

Its super low start-up voltage of 50V represents also an improvement over GoodWe’s NS inverter, permitting in this way longer electricity generation hours, something that definitely is another clear advantage over other alternative inverters in this segment.

As opposed to other inverters with single communications options, the communications of the XS are diversified, offering LAN and Wifi, which is perfect to meet the special requirements of different kind of users. For those groups such as old age groups or dwellers of social housing projects that may be inconvenienced by the setting up of Wifi or Wifi’s reconnection issues, the XS LAN communication system is perfect. Alternatively, WiFi connections are also available.

To conclude this list of attributes, design wise, the XS is a very stylized inverter, conceived to maintain the aesthetical harmony of the whole setting where it is installed. It´s is quite certain that many users will recognize it as a pretty cool solar appliance.

Rolls-Royce has signed a contract with C-Energy to extend their power plant installed capacity with further 23 MWe. The delivery includes two gas-fired gensets based on the new 20 cylinder Rolls-Royce medium speed V-engine, B36:45, that was launched at the Power Gen Asia in September this year. Rolls-Royce will also be supplying long term services for the new engines.

The new B36:45 engine series set a new standard in power and efficiency with exceptionally low fuel consumption and emissions of NOx, CO2, SOx and particulates. At 600 kW per cylinder it offers a 20 per cent increase in power per cylinder compared to its predecessor, the B35:40. The V20 is the largest variant available with an electrical output of 11,8 MWe.

The existing 60 MWe power plant of C-Energy was reconstructed in the beginning of 2015 with four B35:40V20 gas engines. At this time, this was the first natural gas power plant based on medium-speed gas engines in the South Bohemian Region prepared to supply heat and power to the local grid. Due to low coal prices however, electricity and heat in the region is still predominantly generated by coal-fired plants. Hence, the extension of the gas fired plant is considered as an additional step forward towards a green future for the region and country.

With the extension, the power plant will, from the end of 2019, deliver a total of 83 MWe electricity and heat for companies and homes in the nearby town of Tabor/Sezimovo Ústí roughly 100 kilometers southeast of the capital Prague.

Delivery of four Rolls-Royce engines among other investments helped to transform the old coal fired central heating plant into a modern power plant in 2015. Nowadays the plant not only supply power to the grid and heat to industrial customers and municipalities but also provide auxiliary services to the high voltage grid. The supply of brand new Rolls-Royce engines will enable the plant to increase its flexibility, to provide wider range of services and hence remain competitive on the pan European energy market.

The Rolls-Royce medium-speed engines will enable C-Energy to operate the plant efficiently, both in terms of cost and time. Both the B35:40 and the new B36:45 medium speed gas engines are flexibly designed for different operating modes. They can be used to generate base-load or peak power or can operate in combined cycle. The heat from the engines can be used to generate steam in the heat recovery steam generators, and the steam is supplied to industrial customers for their technological needs. The power plant can also be used for district heating by utilizing hot water from the engines.

The engines quick-start capability means the engines can ramp up to their rated load within five minutes, giving the plant access to the amount of power and heat needed within just a short space of time. In addition the new engines will be certified to provide primary and secondary grid regulation.

The new MTU Onsite Energy 20V 4000 DS3600 genset was recently launched on the market. Based on enhanced MTU Series 4000 engines, the 20V 4000 DS3600 diesel genset significantly outperforms previous offerings with a 10% uplift to around 3,000 kW of electrical output (3,730 kVA) in standby operation, and some 2,700 kW of electrical output (3,390 kVA) when generating prime power. Earlier models of this Series 4000 engine have a proven track record with over 23,000 units sold for power generation applications.

More than 30 of these new units are already set for delivery in 2018. Most of the initial consignment, supplying 75 MW overall, is destined for a global internet group to generate standby power for its European data centre. MTU Onsite Energy has already announced further advancement to an even higher level in the form of the 20V 4000 DS4000 diesel genset delivering roughly 16% more output, amounting to as much as 3,200 kW of electrical output (4,000 kVA of standby power), compared with previous offerings. At around 20 m2 both units take up strikingly little space.

Optimized engine design boosts performance

Steadily increasing power demands in mission-critical applications, like those encountered in data centres, airports or hospitals, necessitate the use of ever more powerful engines – such as the enhanced Series 4000 from MTU – to allow the gensets to step in smoothly and cover demand should a contingency arise.

Performance has been boosted by optimizing engine design to allow for a higher BMEP (brake mean effective pressure ) in the cylinders, and fitting a redesigned turbocharger and modified peripheral equipment with some astutely matched components.

Genset beats the standard

In-house expertise in all the key technologies involved here, coupled with state-of-the-art simulation and analysis tools, have allowed to develop a generation of engines with which the new diesel genset can even beat the standard. One reason is the high engine load factor which allows the standby genset to be operated at 85% of its maximum power on average – a value which surpasses the requirements set out in ISO-8528-1 by 15%. What’s more, the generator can run for up to 500 hours a year in its vital standby power role. This value goes way beyond the 200 hours specified in the standard.

In case of a power outage, delivering a dependable power supply in a matter of seconds is key. Data centres with their sensitive IT facilities present the additional challenge of mitigating fluctuations in voltage and frequency. These gensets have therefore been developed to curb these variations by design. Receiving the first order for the new genset from a global player in the Silicon Valley is a great honour.

Certified to feed the public grid

Series 4000 gensets comply with VDE guidelines (the German Association for Electrical, Electronic & Information Technologies) and are certified for mains parallel operation. This allows users to feed power into the public grid at a profit as well as safeguarding supply in case of an emergency. In terms of energy efficiency, this is also a sensible approach to dealing with the increasingly common grid instabilities resulting from the use of renewables. Certified diesel gensets from MTU Onsite Energy tick all the boxes in meeting the technical criteria for doing just this.

Europe added 4.5 GW of wind energy capacity in the first half of 2018, according to figures released by WindEurope. The figure is down on the same period last year (6.1 GW) though is in line with expectations.

There was 3.3 GW of onshore wind, driven by Germany (1.6 GW), France (605 MW) and Denmark (202 MW).
The 1.1 GW of offshore wind was mainly in the UK (911 MW), Belgium (175 MW) and Denmark (28 MW). Germany is set to install new offshore wind in the second half of the year.

For the whole of 2018, we expect to see 3.3 GW new offshore wind and 10.2 GW of onshore wind. This will mean 13.5 GW of new wind capacity in total for the year.

France has installed a lot of new onshore wind this year but they haven’t issued a single new permit for onshore wind permit in the last eight months because of an administrative issue – which has also resulted in their latest auction being under-subscribed. So there’ll be a drop-off in their new build now, creating uncertainty in the supply chain.

In Germany it’s good that projects now need a permit to bid into onshore auctions, but that rule now needs to be made permanent. Also, there’s no clarity yet on when the 4 GW new onshore wind promised in the coalition agreement for 2019-20 is going to be auctioned. And the new Government is slow in confirming the auction volumes beyond that. Like all Member States they now need to give five years’ visibility on future auction timetable and volumes – under the terms of the new Renewables Directive.

This visibility is key to the supply chain and to keep wind energy jobs and growth in Europe. Investments in manufacturing, skills and R&D only happen when governments give long-term visibility to the supply chain. This clarity helps them to make new investment decisions and bring down costs. Addressing these issues will be key to enable Europe to meet its target of 32% renewable energy by 2030 cost effectively.

And in offshore wind, Europe is too dependent on the UK, which is striding ahead in current installations and in committing to future volumes. By contrast, the rate of new installations has slowed down in Germany. Other countries also need to beef up and speed up their plans on offshore wind.

A consortium comprising EPC contractor TSK and Rolls-Royce has signed an engineering, procurement and construction (“EPC”) contract with Prime Energía Quickstart Spa, a subsidiary of Prime Energia SpA (“Prime Energía”), for the construction of five power plants across Chile consisting of 265 MTU Onsite Energy 16V 4000 gensets. Prime Energía is a subsidiary of the New York-based Glenfarne Group, LLC (“Glenfarne”), a developer, owner-operator and industrial manager of energy and infrastructure assets. Prime Energía’s five power plants will offer a total combined capacity of 475 MW, which will be connected to Chile’s electricity grid to provide backup capacity to the country’s power supply system.

These power plants are an integral part of Glenfarne’s strategy to develop power infrastructure that supports the proliferation of renewables and the stability of the grid in regions across the Americas with great potential for growth.

The order to deliver the power plants to the first three locations has been officially placed with the consortium, with the order for the two additional plants scheduled to follow shortly thereafter. The gensets will be digitally connected via gateways sending data to the MTU GoManage platform to monitor and analyse system data. The power plants will be remotely monitored and controlled in real time by Prime Energía’s state of the art Network Operations Center in Santiago.

Chile is one of the fastest growing economic powers in Latin America. Demand for energy is expected to grow at an annual rate of 4 per cent over the next 5 years, and the country expects to benefit from the vast availability of renewable power sources. The percentage of renewable energy in the Chilean power mix is growing at a constant rate: its share, in terms of installed generation capacity, has more than tripled since 2012, and in 2017, with a total plant capacity of around 4,300 MW, was approximately 18 per cent. By 2035, no less than 60 per cent of the country’s electricity is expected to be produced from renewable energy, increasing to 70 per cent by 2050. As Chile increases its reliance on weather variable renewable energy sources, there will be an increased requirement for fast-response, cost-competitive backup power sources such as the power plants in Prime Energía’s portfolio to stabilise the electricity grid.

Abengoa takes part in the european Grasshopper (GRid ASsiSting modular HydrOgen Pem PowER plant) project, leading the design, construction and testing of a pilot plant, for subsequent scaling to MW. The objective of this new project is the creation of the next generation fuel cell power plants (FCPP) suitable for a flexible operation for grid support. The power plant will use green hydrogen and convert it into electricity and heat without emissions. With the variations in demand and consumption of energy from renewable sources such as sun and wind, a stable energy supply will rely more and more on flexible operation power plants.

The consortium consists, apart from Abengoa, INEA-Informatizacija Energetika Avtomatizacija, Johnson Matthey Fuel Cells Limited (JMFC), Nedstack fuel cell technology B.V., Politecnico di Milano (Polimi) and Zentrum für Brennstoffzellen Technik Gmbh (ZBT).

The development of a fuel cell system, with significant innovations in the membranes and other components, will be done through modelling, experiments and industrial experience by JMFC, ZBT and Nedstack. Polimi will provide support in the decision-making process through modelling activities and optimization. Implementation of the smart grid functionality into the FCPP control and grid integration will be done by INEA.

The demonstration unit will be installed in Delfzijl, where Akzo Nobel and Nedstack have been testing the fuel cell technology for over 10 years now, connecting to the hydrogen by-product stream of the modern chlorine production facility.

The kick-off meeting of the Grasshopper project took place at the beginning of January 2018 at the Akzo Nobel facilities, in Delfzijl, with the participation of the consortium partners, the members of the Advisory Board and the Project and Financial officers from the Fuel Cells and Hydrogen Joint Undertaking (FCH JU), unique public private partnership supporting research, technological development and demonstration (RTD) activities in fuel cell and hydrogen energy technologies in Europe. The demonstration phase and the end of the project will take place in Akzo Nobel facilities.

The Advisory Board, consisting of members from Akzo Nobel Industrial Chemicals B.V, Tennet TSO B.V, SWW Wunsiedel and members of GOFLEX consortium, will be consulted during the project phase.

Coordinated by INEA, the project Grasshopper will have a duration of 36 months a total budget of 4.4 M €. This project has received funding from the Fuel Cells and Hydrogen 2 Joint Undertaking under grant agreement No779430. This Joint Undertaking receives support from the European Union’s Horizon 2020 research and innovation programme, Hydrogen Europe and Hydrogen Europe research.

According to a new report from ecoprog, in early 2017, there were 3,510 operational biomass power plants worldwide, generating electricity and heat from solid biomass and with a total installed capacity of 52.8 GW. By the end of 2017, ecoprog estimates that there will be around 3,700 active power plants, with a capacity of some 56.2 GW. In just one year, 200 biomass power plants with a capacity of almost 3 GW were commissioned. While Europe showed a slight decrease in newly commissioned biomass power plants over the past year, Asia’s commissioning rate remains at a high level. In North America, low electricity prices have resulted in commissioning insecurities, with the commissioning rate slowing in 2016/2017. The attractive incentive scheme in Japan resulted in a growing commissioning rate in the Australia and Pacific region. At the same time, consolidation and globalisation continued among the technology providers in 2017.

The market for biomass power plants, the number of plants and their respective capacities, is a result of the subsidisation schemes and the availability of positive economic conditions at favourable locations, e.g. in the sugar or the paper industry. Regions with high political subsidies in the form of feed-in tariffs have comparatively young plant assets that are characterised by small-scale plants. This is the case in most European countries. Today, many systems primarily subsidise small-scale plants due to ecological sustainability. Europe’s plants are therefore on average smaller than in other regions such as North America. By contrast, fuel availability is the determining factor in North and South America as well as in many Asian markets, as subsidisation levels are often lower than in Europe.

North America and Europe mainly use wood to generate energy, while South American countries primarily incinerate bagasse, a waste product of the sugarcane industry. Agricultural residues such as straw, rice husks and empty fruit bunches from the palm oil industry represent the main fuels in Asia. Read more…
