Wärtsilä has been contracted to add a 10 MW/26 MWh energy storage solution to a power plant owned by Roatan Electric Company (RECO) on the Caribbean island of Roatan in Honduras. Wärtsilä’s proprietary GEMS energy management software solution will control the utility’s energy system, including earlier delivered Wärtsilä engines, and solar PV. The order was placed with Wärtsilä in December 2019.

The addition of energy storage and GEMS solution to RECO’s generation resources will provide additional flexibility to integrate renewables into the local grid and secure reliability while eliminating the need for mechanical spinning reserve. The storage system will provide virtual spinning reserve capacity needed to maintain stability of the grid – particularly important for the energy security of an island. The solution will be delivered on a fast-track basis and is expected to be operational before the end of 2020.

The system will allow more cost-effective and optimised operation of the existing thermal power plant, plus enable more renewable energy to be incorporated into the system. It’s anticipated that by the end of 2021, over 20 percent of the delivered island energy will come from renewable sources. This is made possible by an integrated energy storage solution using tertiary control from the GEMS software.
The existing 28 MW plant was delivered on an engineering, procurement and construction (EPC) contract by Wärtsilä in 2017. It operates on four Wärtsilä 34SG-LPG engines running on propane gas.
Wärtsilä’s total installed power capacity in Honduras is approximately 500 MW.

RECO is constructing 12.5 MW of solar PV energy, has a 26-turbine wind farm, and a recently completed a 6-mile underwater subsea cable to expand their distribution system to two nearby islands.

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.

Many sectors – industrial production, building systems and mobility, to name but a few – have yet to achieve the full benefits that digitization of energy management can offer. From 1 to 5 April, experts will gather at HANNOVER MESSE to discuss the areas and ways in which digital processes can be further leveraged to conserve energy and resources and reduce costs.

The upcoming HANNOVER MESSE will again feature a special Digital Energy showcase in Hall 12, where innovative companies from around the world will present ideas and solutions for digitizing the entire energy sector.

A key focus will be on smart meters, particularly Germany’s nationwide rollout, which is currently gathering pace. Nationwide rollout of smart, digital electricity meters is fundamental to further efficiency gains and, indeed, to the energy transition. Hans-Jürgen Schmitt, CEO of PCVue Solutions , explains: “Building automation systems and indeed the electric power system as a whole cannot work properly unless all electricity meters are capable of transmitting their consumption readings digitally, because only then is it possible to achieve efficient, profitable energy management“. Smart meters are the all-important ‘last mile’ in energy system digitization.

The smart meter technology itself has been around for quite some time and is capable of measuring the electricity consumption of any device in any setting, be it in the home, in large public buildings or in factory halls. And there are many providers, including, for example, Germany’s B+G E-Tech GmbH , which offers a whole range of meter types. “Demand is growing, and our clientele is very diverse, ranging from end consumers to industrials,” says CEO Mathias Bruchholz. He believes the increasing demand is due to heightened energy awareness, with many customers now pursuing the benefits of reduced energy consumption. This view is echoed by Werner Derlet, a product manager with the German software provider FlowChief GmbH . He has noticed a greater awareness of energy efficiency. Working closely with engineering firms, FlowChief develops customized energy management systems for companies in a range of industries, including chemicals and wastewater treatment. FlowChief will be showcasing its “e-Gem” product at the Digital Energy pavilion at this year’s HANNOVER MESSE. e-Gem is an energy management software application that can be accessed via browser, enabling users to keep tabs on all aspects of their energy consumption from any location.

While awareness of energy efficiency is growing, many sectors of society still have some catching-up to do. This is certainly true of Germany’s public sector and its extensive building portfolio. “Using our software, our customers are discovering they can reduce their energy consumption by 5 to 30 percent without any drop in climate control performance and comfort,” says Stefan S. Hindrichs, CEO of synavision GmbH , a provider of software for the intelligent monitoring of automation functions in technical building systems. But while energy cost savings of up to a third sound promising, Hindrichs adds a word of caution: “To actually achieve better energy efficiency in buildings, we need the precision of digital tools and processes at all stages, from building planning, right the way through to operation.”

Daniel Fierus-Beyer, CEO of PQ Plus GmbH, another Digital Energy exhibitor, notes that timely planning and long-term planning certainty are also important when it comes to operating and upgrading power grids. The same is true, he says, of electricity quality, especially now that power grids are receiving ever greater in-feeds from solar, wind, hydro and biogas. Based in Germany, PQ Plus GmbH specializes in energy management, providing a wide range of solutions, including multi-channel meters for monitoring and verifying grid quality. Fierus-Beyer explains that the growth in fluctuating green in-feeds is not the only problem for power grids. Sector coupling is also a challenge: “More and more people are charging their electric cars overnight, so next thing you know, residential areas will be looking more like industrial zones in terms of electricity demands.”

This phenomenon – the convergence of industrial manufacturing, power grids, renewable energy and mobility as a result of digitization – will also feature at the showcases of many other exhibitors at the Digital Energy display, including Athion GmbH , econ solutions GmbH and GreenPocket GmbH. TQ-Systems GmbH will also be there, back after its successful debut last year. “This year, our showcase will focus on intelligent charging management in electric mobility,” explains Jörg Jungbauer, head of TQ’s Automation division. “We will be presenting a solution for achieving charging infrastructure in industrial and commercial settings. We’ll also be presenting our patented Energy Manager, which puts modular energy automation in the hands of home owners.” Enapter GmbH will also be exhibiting at Digital Energy. Enapter, a start-up, offers electrolyzers for end consumers. “We’ll be disrupting the hydrogen market with our affordable and simple-to-use technologies,” says Marketing Director Vaitea Cowan. With all of these exhibitors and solutions in store at the upcoming HANNOVER MESSE, it’s clear there’s a lot happening in today’s increasingly digital and renewable energy sector

    Capgemini’s World Energy Markets Observatory report 2017

    Capgemini, has published the nineteenth edition of its annual study, which for the first time goes beyond Europe and becomes the World Energy Markets Observatory (WEMO) report, built in partnership with the I4CE, De Pardieu Brocas Maffei and Vaasa ETT teams. The study reveals that progress in the sector’s generation technologies has caused an acceleration in the Energy Transition, while related renewables growth continues to destabilize the wholesale electricity markets and key players. The study also highlights a profound change in customer energy usage, behaviors and expectations, with, for example, self-consumption, smart homes, smart buildings, smart plants, smart cities and the creation of communities to purchase or manage energy differently.

    As a result, the financial situation of established Utilities remains challenging. The report encourages utilities to accelerate their transformation efforts and to leverage increasingly the power of digital transformation.

    The three main findings of the 2017 edition of the World Energy Markets Observatory report are:
     
    Rapid evolution of generation technologies makes the renewables penetration unstoppable, thanks to their competitiveness gains, and despite the end of feed-in tariffs in Europe

    During the past 12 months, the costs of renewable energies have continued to fall: onshore wind and utility scale photovoltaic (PV) costs are becoming competitive in some countries, compared to traditional electricity generation resources (nuclear, coal, gas). A recent auction for solar PV generation plants recorded a lower cost in sunny Saudi Arabia, with only 17 $/MWh. Battery storage costs decreased also by about 20%. The ingredients now gathered favor Energy Transition with limited political intervention.

    According to Colette Lewiner, Energy and Utilities senior advisor at Capgemini, “Efforts in R&D and industrialization are boosting renewable energy development, even when considering extra network investments linked to intermittence and energy generation distribution. Today, their intermittency coupled with the absence of pricing reforms, mean the impact of renewable energy on the wholesale markets prices threatens electricity supply and impacts negatively utilities’ finances.”
     
    Empowered smart energy consumers are pushing Utilities to deliver new energy services.

    All customers (residential, tertiary or industrial) now expect from their suppliers’ offerings better management of their energy (examples include self-consumption, smart home, smart building, smart plant, electric mobility). With the participation of the customer in energy communities, the way energy is purchased or managed collectively is also now evolving.

    For Perry Stoneman, Head of the Energy and Utilities sector at Capgemini, “We observe many Utilities creating new customer divisions that are focused on chasing the Holy Grail: the differentiating services valued by the customer, allowing the development of new revenue streams with better margins. With variations from one country to another, the vast majority of players are moving in that direction, but very few, for the moment, have found the appropriate recipe. Innovation capabilities and agility for a rapid and successful go to market are generally missing.”
     
    Established Utilities, heavily hit by Energy Transition and customers’ evolving expectations, have started large transformations. It’s now time to accelerate by leveraging Digital Transformation.

    Most of the big players have launched transformation plans that they are executing with a particular attention. This is also the case in North-America, where the Utilities’ finances are less challenged than in Europe, thanks to a lower pace of Energy Transition and different market rules. In addition to simplifying their internal processes, these transformation plans generally focus on the downstream business (networks, green energy and customers’ energy services), designing and managing new operations and business models. Gains could also be sought in the generation side of the value chain. Digital technologies are evolving continuously to provide new solutions (for example Robotic Processes Automation, Artificial Intelligence, Internet of Things, or Blockchain were not available a couple of years ago). The value of managed data – Analytics – remains also largely unexploited.
     
    The World Energy Markets Observatory is an annual publication by Capgemini that monitors the main indicators of the electricity and gas markets in Europe, North America, Australia and South-east Asia, and reports on the developments and transformations in these sectors. This 19th edition, which is drafted mainly from public data combined with Capgemini’s expertise in the energy sector, refers to data from 2016 and winter 2016/2017. Special expertise on regulation, climate challenges and customer behavior is given respectively by De Pardieu Brocas Maffei, the I4CE – Institute for Climate Economics – and VaasaETT research teams.

    The buildings in which Europeans sleep, eat, shop, learn and work, house a great opportunity for energy saving and emissions reduction, particularly in the so-called technical systems: heating, DHW, cooling, ventilation and lighting. A recent study by energy consultancy Ecofys, sponsored by Danfoss, shows the energy saving that can be achieved by improving energy management in Europe’s buildings. This hitherto under-exploited potential is calculated to save €67bn on the annual energy bill of European citizens by 2030, while reducing CO2 emissions by 156 Mt. Documents have been published as part of the study that focus on different types of buildings. This article sets out the main conclusions of the study in the case of supermarkets, along with some of the more recent success stories from Danfoss in this sector on the Iberian Peninsula.

    Buildings allocated to supermarkets in Europe occupy an approximate surface area of 115 million square metres. Part of the study included an assessment of the energy saving potential of a sample supermarket with a surface area of 1,025 m2 and a total energy consumption of 181 kWh/m2a. This sample building is equipped with a gas condensing boiler for heating (with energy recovery for the refrigeration system); mechanical ventilation systems with no heat recovery; a refrigeration and air conditioning system by means of compression chillers; and a direct and indirect lighting system via fluorescent tubes.

     

    Improvements to the technical systems in this sample supermarket reveal the possibility of achieving a 45% saving in energy, which translates into just over 8,000 €/year, with an investment of some €36,000 that would be amortised in around 4.5 years. Read more…

    Acciona Energía has started up the first hybrid plant for storing electricity in batteries that is part of a grid-connected wind farm in Spain. The company has also developed simulation software that will be used in the plant, for which it has been awarded the ‘Eolo Innovation’ prize for by the Spanish Wind Energy Association (AEE). These two projects make the company a pioneer in this kind of solutions, aimed at facilitating the integration of variable-generation renewables into the grid and optimizing the management of the power produced.

    Located in Barasoain (Navarra, northern Spain), the plant is equipped with a storage system consisting of two batteries located in separate containers: one fast-response 1 MW/0.39 MWh power battery that can maintain 1 MW of power for 20 minutes, and another slower-response battery with greater autonomy of 0.7 MW/0.7 MWh that can maintain 0.7 MW for 1 hour. Both batteries are of Li-ion Samsung SDI technology and are connected to a 3-megawatt rated capacity AW116/3000 wind turbine of Acciona Windpower (Nordex Group) technology. The batteries will store energy produced by the wind turbine when required. The turbine is one of five that make up the Barasoain Experimental Wind Farm, which the company has operated since 2013.

     

    The installation also has three other units: one for medium voltage cells and analyzers, another for inverters/chargers and a transformer (installed by Ingeteam, a company participating in the project), and a third for the control and monitoring equipment.

    In the plant, grid-connected storage solutions will be put in practice in order to provide advanced technology services aimed at improving the quality of the energy sent to the grid. Other applications will also be analyzed, such as ancillary services to the electric power system –necessary to maintain a continuous balance between supply and demand– or the energy supply shift to match the production to periods of higher demand, which improves the economic performance of the installation.
    The project has received funding from the European Regional Development Fund (ERDF), which manages the Spanish Centre for Industrial Development (CDTI).

    Optimizing storage

    A key element of the innovation work carried out by Acciona in this field is the simulation software developed in-house. It means that storage systems can be dimensioned and optimized in synchronization with wind farms, whether they are in the project phase or fully operational. Bearing the Spanish acronym ‘ADOSA’ (Analysis, Dimensioning and Optimization of Storage Systems), it is an innovative tool with the special feature that it covers technical, economic and strategic aspects in an integrated way, meaning that the optimal solution can be found for each case.

    The Spanish Wind Energy Association has just awarded its top prize in the field of R&D – the Eolo Innovation prize – to this project, the brainchild of engineers Asun Padrós Razquin and Raquel Rojo Ochoa, who work in the Innovation Direction of ACCIONA Energía.

    Expectations for the future

    The application of electric power storage systems using batteries connected to wind farms and solar plants is a field with great growth potential due to the major development of renewable energies worldwide, lower battery technology prices and improved efficiency.

    Although still in an early phase, this kind of solution is demonstrating that it is ideal not only for domestic applications or grids with poor connections (islands, weak grids) but also for utility-scale applications in developed countries, with a focus on increasing the penetration of variable renewables in power grids without losing quality or security, and on adapting electricity supplies at times of higher demand. Basically, it is about improving the flexibility of electric power systems to incorporate greater renewable capacity, in a context of a shift towards a low-carbon energy mix in which fossil fuels will be gradually replaced by clean technologies.

    According to the International Renewable Energy Agency (IRENA), battery storage is even better for providing a fast response to electric power system regulation demands than conventional fossil fuel plants, which have traditionally provided these ancillary services.

    Analysts expect strong growth in storage systems over the next few decades. The consultancy firm Navigant forecasts revenues in utility-scale projects of 18,000 million dollars in 2023 against 220 million in 2014, a period in which the annual storage capacity in batteries will go from 360 MW to 14,000 MW.
