The technology group Wärtsilä has commissioned its 6 MW/6 MWh energy management and storage system project for its customer ContourGlobal Bonaire on the Caribbean island of Bonaire. With Phase One complete, the island no longer has to curtail wind resources. It has nearly doubled renewable energy penetration, and prepared the system for additional capacity to accommodate peak demand during tourist season. ContourGlobal’s entire island grid is managed and operated by Greensmith GEMS advanced software platform.

The utility’s phased approach allows time for system operators to add new hybrid solutions and spread out costs, and leaves room for new technologies to come online. For Bonaire, Phase One involves GEMS managing an optimising dispatch and operation of existing generation assets. It also provides spinning reserve requirement with energy storage to reduce fuel consumption and emissions. Furthermore, Phase One involves unlocking curtailed wind energy and improved system reliability by providing frequency and voltage control. To optimise the system GEMS now factors in real-time asset performance, as well as load and renewable energy forecasts. With Phase One complete, GEMS can balance Bonaire’s resources and seamlessly optimise thermal, wind and energy storage assets.

During the commissioning tests, several load rejections were tested, including loss of wind, loss of engines and loss of demand, and in every circumstance GEMS instantaneously tracked and maintained the quality of the generation avoiding the load shedding of the grid. This is just one example of how this project will improve operations through automation while helping the island avoid blackouts, achieve greater efficiencies and use more wind power.

Commissioning of the project puts Bonaire on the path to achieving its 100% renewable target. This is the beginning of a longer-term plan to fully modernise the island’s system and add additional capacity and renewable energy generation to the grid. ContourGlobal Bonaire commissioned the project after years of seeking solutions to integrate more renewable power into the existing island grid.

The next phases for the Bonaire project will replace outdated thermal technology with five new engines and add more wind and solar to the generation mix. As the island grid increases in size, GEMS will enable further renewable penetration and lower the cost of energy. GEMS machine learning and AI capability will incorporate weather, electricity demand and other variables and data into its forecasting models. This data will inform the automated decisions managing ContourGlobal’s entire fleet.

Rolls-Royce and ABB have announced a global partnership on microgrid technology and advanced automation. Together the two companies will offer an innovative, energy-efficient microgrid solution for utilities, commercial and industrial entities. A microgrid is a small scale electric grid that combines power from distributed energy generation sources such as combined heat and power plants, diesel- and gas-powered gensets and renewable sources with batteries. The microgrid provides the overall control to coordinate these resources to meet the requirements of industrial, residential or consumer loads. Microgrids can either function off-grid, or connected to the main power grid. The ability of microgrids to seamlessly separate themselves from the main grid, in the event of a potential grid fault or emergency, is an in-creasingly important feature.

Reliable power supply – even during harsh weather conditions and times of peak consumption – is critical for economic growth. Integrating renewable energy is a sustainable solution to support uninterrupted power as well as encourage clean energy use. Microgrid solutions benefit utilities, industries and commercial sites that are looking for reliable power supply as well as cost and carbon emission reduction.

Microgrids enable resilient power supply even with high penetration of intermittent renewable energy sources like wind and solar. Digital automation and control systems intelligently coordinate distributed energy resources and loads for the microgrid to function efficiently.

Rolls-Royce offers the MTU Onsite Energy brand power system solutions: from mission critical, standby and continuous power to combined generation of heat and power, and microgrids. “Due to the transformation towards decarbonization, customers need to pursue sustainable power options that also deliver utmost profitability. For this, we rely primarily on microgrids, which are autonomous energy supply systems that are efficient, reliable, and environmentally friendly,” said Andreas Schell, CEO, Rolls-Royce Power Systems.“Combining our integrated MTU diesel and gas genset system technology and our control solutions, with ABB’s modular microgrid solution, control capability and remote service, will offer customers the combined strengths of the two world leaders in technology.

ABB Ability™ e-mesh™ can ensure a stable power grid, even with a high share of renewable energy from various sources, working smoothly together with already installed gas or diesel engines,” said Massimo Danieli, head of ABB’s grid automation business line within the company’s Power Grids business. “ABB has a vast number of microgrid installations globally and through our partnership with Rolls-Royce Power Systems, we will further support the growing interest for microgrid solutions globally.

The ABB Ability™ e-mesh™ solution will provide power generation asset owners a vertically integrated, unified view of their distributed energy resources and renewable power generation that is quick to deploy and that reduce operational costs. Cloud operations, site and fleet optimization, weather and load forecast and machine learning algorithms offer infinite insights for decision-making, such as knowing where to increase investments on maintenance or how to increase revenue streams to operate assets more profitable.

To date, Ingeteam has supplied 140 MW to Chile for solar projects coming under the Distributed Generation by Small Power Producers (PMGD) program, which supports the execution of generation projects with rated powers of up to 9 MW.

Distributed generation is an ongoing trend in Chile and in many other countries, accounting for one quarter of global investment in renewables in 2015. To promote the construction of projects of this type, the PMGD program gives PV plant owners the guarantee that they will be able to sell all their output to the electricity grid. Moreover, the National Energy Commission (CNE) allows these producers to choose between the sale of energy at either a marginal cost or stabilized price. In this latter case, producers are guaranteed stable prices that are higher than market prices, given the fact that these prices are calculated every six months by the CNE and are not subject to a time of day variation.

In the past two years, Ingeteam has supplied its PV inverters for ten solar projects of this type and is now supplying fourteen of its Inverter Stations with 1500V technology for seven solar PV plants that are being built by Grenergy, a company that also decided to install Ingeteam’s PV inverters at the La Esperanza, Marchigüe, Mostazal and Luders photovoltaic plants. Thanks to the supply of PV inverters for these last seven projects, Ingeteam has reached a total power of 140 MW at plants coming under the PMGD program in Chile. Ingeteam also has a portfolio of upcoming projects for this country, in which it holds a privileged position in the PV inverter manufacturer ranking.

In order to ensure a correct operation of the electric system, a project under the PMGD program must implement functionalities as minimum electric protections at the coupling switch. These functionalities are performed by Ingeteam’s PL70SV, already in operation in more than 20 installations of this kind. Ingeteam has supplied protection and control systems to the Chilean market to connect with the electric grid 12 renewable energy power plants –wind and solar PV-, totaling more than 1,100MW.

Furthermore, since Ingeteam first started operating in Chile, five years’ ago, the company has also gone on to secure its position as a leader in the operation and maintenance of renewable energy generating plants. In Latin America, the company provides maintenance services to a total of 2.5 GW, of which 664 MW correspond to Chile, accounting for 33% of the country’s total installed renewable power. In the solar sector in Chile, Ingeteam maintains a total of 330 MW. This record figure was primarily achieved thanks to the presence of Ingeteam in the Atacama desert. In fact, Ingeteam is going to supply the integral O&M service to four of these solar farms: Cachiyuyo Solar, Malaquita Solar, Valle Solar Este and Valle Solar Oeste. For the rest, the company will provide after-sales service.

The first offshore wind farm one hundred per cent designed and operated by a Spanish company

Iberdrola has officially cut the ribbon on Wikinger offshore wind farm, one of the company’s most iconic power plants in the world, having invested over €1.4 billion. Wikinger is fully operational and its 350 MW are connected to the German grid, supplying efficient renewable energy to 350,000 homes (representing some 20% of the energy demand of the state of Mecklenburg-Vorpommern). This flow of clean energy will have a positive environmental impact since it displaces the emission of nearly 600,000 tons of CO2 per year.

The Wikinger project marks Iberdrola’s entry into the German electricity market, where it has just been awarded the construction of two other offshore wind farms: Baltic Eagle (476 MW) and Wikinger Süd (10 MW). Together with Wikinger, these three wind farms, located off the island of Rügen, will give rise
to the largest offshore wind complex in the Baltic Sea, with a total installed capacity of 836 MW and a combined investment of €2.5 billion.

Wikinger is the first offshore wind farm to be designed and operated one hundred per cent by a Spanish company. It has consolidated Iberdrola as Europe’s leading company in renewable energy, capable of developing projects in markets as competitive as Germany and meeting the demanding planning conditions set by German authorities. In addition, it has served to boost the entire supply chain, benefiting companies across Europe, including Navantia and Windar.

This project has come to fruition thanks to the multidisciplinary and multinational composition of the team set up by Iberdrola and its network of first-rate international suppliers and contractors. Over 2,000 employees from 20 different countries participated in this milestone project. Iberdrola has had to overcome the technological challenges inherent to this type of work and the difficulties arising from the extreme weather conditions in the Baltic Sea.

Wikinger, a mark for Iberdrola

Located off the north-east coast of the German island of Rügen, Wikinger brings together the main themes of Iberdrola’s strategy: strong investment in the development of renewable energies, commitment to reducing emissions, technological innovation, international growth, opening of new markets and business lines to its suppliers, and an important boost for the European naval industry.

To build the project, 280 piles were installed. Measuring 40 metres in length by 2.5 m in diameter, and a unit weight of 150 t, they were all built by Spanish company Windar. A total of 70 foundations were laid on them, each weighing 620 t, manufactured by Bladt Industries in Lindo (Denmark) and Navantia, at its shipyard in Fene (Spain).

The 5-MW Siemens Gamesa AD 5-135 wind turbines were manufactured in the company’s plants in Bremerhaven and Stade (Germany). These are the wind turbines with the highest power rating and largest dimensions that Iberdrola has installed thus far. With a total height of 165 m, they are made up of a 75-m high tower, a 222-t nacelle and a 135-m diameter rotor, with each blade measuring 67 m long.

Finally, one of Wikinger’s key pieces of infrastructure is the Andalucía offshore substation, which will be used jointly by Iberdrola and 50Hertz, an electricity system operator in Germany. Weighing around 8,500 tonnes, the energy heart of the wind farm was also built by Navantia in Puerto Real in southern Spain.

Commitment to offshore wind power

Offshore wind energy is one of the keys to Iberdrola’s growth and the company has undertaken notable projects in this sector in the United Kingdom, Germany and France. These large investments will help advance the transition to a decarbonised energy model and combat climate change. These are the main projects underway:

West of Duddon Sands (WoDS): Located in the Irish Sea, WoDS was the first offshore wind farm the Iberdrola Group was involved in. It was developed by the company in consortium with Orsted and came into operation in 2014. It has 389 MW capacity and the investment was over £1.6 billion.

East Anglia One (EAO): Mega-project currently under construction in British waters in the North Sea, it will become one of the world’s largest offshore wind farms when it starts operating in 2020. It will involve an estimated investment of £2.5 billion and have a capacity of 714 MW.

Saint-Brieuc: This 496-MW facility will be located 20 km off the coast of Brittany in northern France, about 100 kilometres from the city of Rennes. It will have 62 Siemens-Gamesa turbines, with 8 MW unit capacity.

Vineyard Wind: Iberdrola, through Vineyard Wind, recently received authorisation from the Massachusetts Electric Distribution Companies (EDC) to construct a wind farm off the north-east coast of the United States. The project, which represents the company’s first large-scale offshore wind farm venture in that country will have 800 MW capacity.

Acciona Energía is the first company to apply blockchain technology to certify the 100 per cent renewable origin of the energy fed into the grid from its two storage facilities in Navarre (Spain).
Blockchain technology was successfully integrated into its PV plant in Tudela and its wind farm in Barásoain – the latter becoming the first hybrid storage facility for wind power with batteries in 2017.

Thanks to this technology, Acciona Energía’s clients and other stakeholders are guaranteed that the energy supplied from battery storage facilities comes exclusively from renewable sources that are free of greenhouse gas emissions.

Due to its decentralized and operational characteristics, blockchain technology not only acts as a ‘virtual notary’, certifying that the energy produced is of renewable origin; it also does so in real time and in a transparent way. All these attributes are considered important by renewable energy corporate clients and institutions that are committed to the use of clean energy and need proof of origin to meet their sustainability goals.

Certifying the renewable origin of energy is increasingly widespread, associated with the growth of the corporate procurement of green energy, and blockchain technology can greatly facilitate this service to clients in any part of the world. We are very pleased to have taken this first step in a service that will surely grow in importance over the next few years”, says Acciona Energía Director of Innovation Belén Linares.

With wind and photovoltaic energy

The STORe-CHAIN® system developed by Acciona manages data recorded by power counters in wind and solar plants and matches the energy produced with renewable energy certificates. This data is stored in a blockchain platform that acts as a guarantor of the legitimacy of these green certificates and which can be accessed by a client at any time.

The initiative is part of a wider program called GREENCHAIN®, with which Acciona seeks to certify the renewable origin of all the company’s electricity production using blockchain technology.
The plant at Barásoain is equipped with a storage system consisting of two batteries, one a fast-response 1 MW/0.39 MWh and another 0.7 MW/0.7 MWh, which has greater autonomy. Both are connected to a 3-megawatt (rated capacity) Nordex AW116/3000 wind turbine. Last May the plant received the first certification in the world from DNV GL for a grid-connected electricity storage solution.

The photovoltaic facility near Tudela has a storage system with one 1 MW/650 kWh battery.
Both systems are managed by control software developed by Acciona Energía and are integrated in the company’s Renewable Energy Control Center (CECOER) on a permanent basis.

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.

A little over a year ago, Google announced that it was on track to purchase enough renewable energy to match all the electricity it consumed over the next year. Once completed the accounting for Google’s 2017 energy use it’s official—Google mets its goal. Google’s total purchase of energy from sources like wind and solar exceeded the amount of electricity used by its operations around the world, including offices and data centers.

What do the company mean by “matching” renewable energy? Over the course of 2017, across the globe, for every kWh of electricity Google consumed, it purchased a kWh of renewable energy from a wind or solar farm that was built specifically for Google. This makes Google the first public Cloud, and company of this size, to have achieved this feat.

Today, Google has contracts to purchase 3 GW of output from renewable energy projects; no corporate purchaser buys more renewable energy than Google does. To date, its renewable energy contracts have led to over $3 billion in new capital investment around the world.

The road to 100 percent

Google has been working toward this goal for a long time. Every year, the company signs contracts for new renewable energy generation projects in markets where it has operations. From the time it signs a contract, it takes one to two years to build the wind farm or solar field before it begins producing energy. In 2016, its operational projects produced enough renewables to cover 57 percent of the energy it used. That same year, it signed a record number of new contracts for wind and solar developments that were still under construction. Those projects began operating in 2017—and that additional output of renewable energy was enough to cover more than 100 percent of what it used during the whole year.

Google says that it “matched” its energy usage because it’s not yet possible to “power” a company of its scale by 100 percent renewable energy. It’s true that for every kWh of energy it consumes, it adds a matching kWh of renewable energy to a power grid somewhere. But that renewable energy may be produced in a different place, or at a different time, from where it’s running they data centers and offices. What’s important is that it’s adding new clean energy sources to the electrical system, and that it’s buying that renewable energy in the same amount as what it’s consuming, globally and on an annual basis.

Captura

Looking ahead

Google is building new data centers and offices, and as demand for Google products grows, so does its electricity load. Google needs to be constantly adding renewables to its portfolio to keep up. So the company will keep signing contracts to buy more renewable energy. And in those regions where it can’t yet buy renewables, Google will keep working on ways to help open the market. Googles is working with groups like the Renewable Energy Buyers Alliance and Re-Source Platform to facilitate greater access to renewably-sourced energy.
