i-DE, Iberdrola’s electricity distribution arm, has inaugurated the first electrical energy storage system with lithium-ion batteries for distribution networks in Spain. The project, which is the first in the country, is located in the Murcian municipal district of Caravaca de la Cruz and will improve the quality of the energy supply in the surrounding area, as well as the use of solar energy generated in the area.

The storage system, with a capacity of 3 MWh, can operate in isolation and, in the event of an interruption in supply, will be able provide up to five hours of electricity to the main districts in the surrounding area: Cañada de la Cruz, Inazares, Moralejo, Barranda, El Moral and Los Royos.

Adverse climate and rural environment

The special circumstances in the rural environment around Caravaca de la Cruz have determined the choice of this enclave for this innovative solution.

In recent years, the area has been recording very adverse weather conditions that cause incidents in the distribution network. Also, it is an area consisting of various small and scattered centres of consumption, so a fault can leave several villages without service. To this is added the long distances that have to be covered to reach the source of the problem, which further complicates the resolution of incidents.

The traditional solution would have been to construct 22 km of overhead power lines, crossing environmental protection areas. This is the reason why an innovative solution was chosen, based on energy storage installed at a point where overhead cables intersect, allowing several areas to be served with a single battery.

The project has shown that batteries can improve the continuity of supply in contingency situations, as well as the use of photovoltaic plants connected to the impacted grid, including in isolation using only renewable energy. The batteries, in short, constitute a complement to the conventional local operation.

Smart storage system

There are several large photovoltaic plants in Caravaca de la Cruz that upload electricity to the grid during the hours with the most intense sunlight. A battery with these characteristics is able to adjust the voltage to the appropriate values and be ready to intervene as a second source of power supply in the event of a power failure.

To achieve this, it has a smart storage system that is able to assess the situation and decide what part of the network will remain in operation from the battery, taking into account actual consumption at that time, the generation capacity of photovoltaic plants nearby and the state of charge of the battery, among other aspects.

The system estimates both the consumption and the potential renewable generation power of the solar plants in the area at that time and for the following hours. It can, thus, take advantage of local power generation and, in addition, absorb excess energy, in case of excess production.

The combination of this battery and the electricity produced by the photovoltaic plants in the area will significantly reduce the interruption times in the power supply during an emergency.
Storage and grids, the keys to the energy model of the future

Storage systems are key to addressing the challenges of the energy transition and are destined to become an essential element in the electrical system of the future. This is because they allow the quality of the electricity supply to be improved, ensuring the stability and reliability of the network and integrating and harnessing the energy generated by renewable sources.

Iberdrola is a leader in energy storage, with an installed pumping technology capacity of 4,400 MW, which is currently the most efficient method. It is also undertaking numerous initiatives that combine the use of batteries with renewable energy – wind and photovoltaic – projects, as well as those oriented towards improving the quality of the supply by its grids, as is the case with the installation in Caravaca de La Cruz.

Electricity distribution networks are the circulatory system in the new energy model and an essential platform in the transition toward a decarbonised economy based on competitive, renewable energy. Transforming the grids into smart infrastructure responds to the challenges of an electrified economy, with greater integration of renewables, sustainable mobility, smart cities and consumption models and distributed generation.

In this context, i-DE has allocated 2 billion euros to digitising its electricity networks, with the installation of almost 11 million digital meters, together with the infrastructure that supports them, and the adaptation of around 90,000 transformer centres in Spain, to which it has incorporated remote management, supervision and automation capabilities. It is also currently working on the digitalisation of the low voltage network and is investing in control and operation systems.

I-DE, smart electricity grids

The activities of i-DE the new name for Iberdrola’s electricity distribution arm – include the planning, construction and maintenance of power lines, substations, transformer centres and other infrastructure, as well as operating the system in a way that efficiently distributes energy among the various agents that produce and consume it.

Iberdrola operates a distribution system consisting of 270,000 km of power lines in Spain and is present in 10 Autonomous Regions serving a population of 17 million. In 2018, Iberdrola’s distribution business invested almost €500 m in Spain in projects designed to improve its procedures and customer service channels; complete the roll-out of nearly 11 million smart meters and the supervision and automation of the grid.

Iberdrola’s network business is a significant driver of the Spanish economy, generating more than 10,000 jobs in total (both direct and through its suppliers). In 2018, the company made purchases to the value of €500 m from 2,000 local companies.

On the first day of the event, they will present examples and trends, such as how private, commercial and industry customers can optimize local resources. The second day has presentations in store to share expertise on developments and business opportunities for linking decentralized energy resources with the power grid.

Photovoltaics from every angle

The focus will be on markets, technologies and financing for PV projects at the Intersolar Europe Conference. As well as market development in Europe, this year experts will particularly be shining a light on markets in Africa and in the MENA region (Middle East and North Africa). The International Energy Agency (IEA), for example, is organizing a workshop on the performance and operational reliability of PV, as well as PV systems operations and maintenance. Further sessions will cover the interaction of PV and storage. Participants will also discover valuable information about new applications of solar installations, in façades, on agricultural land and on water.

Everything there is to know about energy storage

The ees Europe Conference offers orientation on battery systems and stationary energy storage systems – covering markets, financing, business models, production technologies and safety aspects. In the “Compare and Contrast” series, for example, experts will introduce energy storage projects and their most important data in short presentations, so they can be directly compared. Further details and practical tips will be provided in the follow-up discussion.

What’s needed for sustainable mobility

Electric vehicles powered by solar or wind are the key to developing a new, climate-friendly and sustainable model of mobility worldwide. Most importantly, e-mobility needs a well-developed, comprehensive charging infrastructure in order to prevail. Power2drive Europe Conference provides answers as to how this infrastructure is developing globally and where promising markets can be found. Further topics include successful business and billing models and legal frameworks.

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.

Fluctuations in the prices of fossil fuels, the need to address climate change and the growing energy demand, present the current energy model with major challenges. To address them at the same time as achieving high levels of efficiency, new hybrid energy models based on renewable energy are emerging that aim to make a better use of resources and facilitate an energy supply over a longer period. This is the case of CSP-biomass plants designed to produce power using ORC (Organic Rankine Cycle) technology. Innergy is active throughout the entire value chain of an energy project with biomass, providing services that range from the development, production and sale of heat and automation generation equipment to O&M. The company enjoys extensive experience in all types of biomass, industrial biomass boilers and both ORC and steam technology, qualifying it to support biomass for this type of energy solutions.

This type of hybrid energy solution is so interesting because CSP plants need sunlight to shine directly onto their mirrors in order to produce electricity. On cloudy days these plants remain stopped, not generating power and requiring energy from other sources. On the other hand, there is energy generation equipment that uses biomass, a sustainable fuel source that is not subject to weather phenomena, but which, despite existing in large quantities, must be used in a controlled and sustainable manner.

By combining both types, solar power is used on clear days, with the cloudy days covered by energy originating from biomass. This ensures that the plant can operate 365 days a year as it is energy independent from monopolies and large corporations, as well achieving price stability. Read more…

SolarReserve has received an environmental approval from the Chilean government to build a 390 MW CSP power station with 5,100 MWh of energy storage. This important milestone marks SolarReserve’s third approval of a solar thermal project that will provide Chile with a non-intermittent, 24-hour supply of energy, at a price competitive with fossil fuel based generation.

Utilizing SolarReserve’s proprietary CSP energy storage technology, the Likana Solar Energy Project in the Antofagasta region of Chile, will be comprised of three 130 MW solar thermal towers, each with 13 hours of full load energy storage. With 5.1 GWh of total energy storage capacity, the facility will deliver 390 MW of continuous output, resulting in over 2,800 GWh generated annually. It will operate at a capacity factor and availability percentage equal to that of a fossil fired power plant, while providing a highly competitive price of power – and with zero emissions.

 

The Chilean transmission system will have difficulty accommodating large amounts of intermittent power. The distribution companies and mining sector require a firm, secure, and stable supply of electricity 24 hours a day. The Likana project will help lower electricity costs for Chilean families and businesses, while safeguarding grid stability.

Highly competitive price of power with no fuel price volatility

SolarReserve will be bidding energy and associated capacity, from Likana and the company’s other Chilean projects, into the upcoming auction for firm energy supply issued annually by Chile’s power distribution companies.

What’s happening in Chile is a preview of the future of CSP with energy storage around the world. Even more remarkable than baseload solar, SolarReserve set a new benchmark for CSP pricing by bidding 6.4 c$/kWh, without subsidies, in Chile’s last auction for energy supply,” said Kevin Smith, SolarReserve’s Chief Executive Officer. “We’ve proven that solar with thermal energy storage can compete head-to-head with conventional energy on both functionality and cost.

This achievement will have far-reaching global impacts, as grids will be able to cost-effectively incorporate solar energy that can:

• Deliver non-intermittent baseload power that is more easily integrated into existing grids, and
• Provide firm capacity to reliably meet demand during peak hours, generating when energy is most valuable, reducing cost and risk for electricity customers.

Minimal environmental impact

As part of SolarReserve’s project development and permitting process for the Likana Solar Project, the company collaborates with stakeholders and local communities to ensure minimal environmental impact. This process includes careful site selection, low water use systems, and extensive environmental studies prior to starting construction. The Likana Solar Project underwent comprehensive environmental assessment under the Chilean Impact Assessment System (Sistema de Evaluación de Impacto Ambiental – SEIA) administered by the Environmental Evaluation Service (SEA), and as a result was successfully awarded an environmental qualification resolution (Resolución de Calificación Ambiental) (RCA), which is the name for the Chilean environmental permit.

At its site in Puerto Rico, Lufthansa Technik uses clean energy obtained from biomass available in the region: Lufthansa Technik Puerto Rico and ENTRADE has signed a comprehensive energy supply contract. The first two trigeneration power plants (55 kW power; 100 kW refrigeration each) came into operation in May in 2×20-foot containers, which will be visually inconspicuous next to the two aircraft hangars at the state-of-the-art overhaul site. The key advantage for Lufthansa Technik is the reliable and on-demand energy supply that is replacing expensive power from diesel.

The facilities in the two aircraft hangars for five medium-range aircraft include a painting line. Excessive temperatures and the resulting failure of the power supply are extremely critical here. To date Lufthansa hasbeen using diesel generators to minimise the risk of power failures. The energy supply in Puerto Rico is comparatively expensive and is not 100% reliable. That’s why they were looking for a viable alternative.

 

The Type E3 power plants can be integrated into standard containers and operate with different kinds of biomass. In Puerto Rico, pellets based on waste wood produced in the region will initially be used as the fuel for environmentally friendly energy generation. The cooperation will involve investigating the scope for using aircraft waste (catering waste) directly from the airport. Catering waste currently has to be disposed of and this is very expensive.

At all Lufthansa Technik sites, both resource conservation and emission reduction play a major role in achieving corporate objectives. The emission-free ENTRADE power plants are the perfect fit – using fuels like waste wood direct from the surrounding area. From ENTRADE’s perspective, the close cooperation with Lufthansa Technik is a significant milestone. Cooperation talks are also in progress with representatives from the considerably larger site in Manila (Philippines).

Yesterday, in La Muela (Aragon), Gamesa inaugurated a prototype of its offgrid system for the supply of power to remote areas without access to the grid, such as islands, mines and certain rural areas. The system is pioneering on account of its bundling of four sources of power – wind power, solar power, diesel-powered generation and energy storage batteries – into a solution with installed capacity of over 2 MW.

The inauguration ceremony, which took place at La Muela (Aragon), was attended by the industry ministry’s head of industry, Víctor Audera, and the mayor of La Muela, Adrián Tello. Gamesa was represented by its Chairman, Ignacio Martín, its Chief Corporate Officer, José Antonio Cortajarena, and its Director of Business Development, David Mesonero, among other executives.

Ignacio Martín, Chairman of Gamesa, sought to highlight the fact that: “development of this system represents another milestone in Gamesa’s quest to resolve energy needs in a sustainable manner. At present, more than 1.2 billion people lack access to electricity. Rural areas of India, South-east Asia, Africa, islands such as Haiti, Indonesia and the Philippines, and other remote corners of the plant, such as jungles and deserts, stand to benefit from these offgrid solutions which can generate cheaper and cleaner power”.

This offgrid prototype is the first to market which, with total installed capacity of over 2 MW, enables the ad-hoc combination of each of the technologies installed depending on specific project requirements with the ultimate goal of generating power yet minimising diesel consumption. The prototype also includes control software custom-developed by Gamesa to facilitate integration of the four technologies.

Specifically, the prototype inaugurated today combines a G52-850 kW wind turbine with 816 photovoltaic modules (245 kWp) and three 222-kW diesel generators (666 kW). The plan is to add a battery capable of storing 500 kWh / 500 kW by the summer. The prototype will generate enough power to meet the needs of 400 families.

“Gamesa’s entry into the offgrid sector represents a fresh technological challenge and a new niche opportunity: development of this class of technology is expected to reach 1,200 MW in the coming years. The advantage of our system is based on its flexibility: it can be tailored for customer needs by increasing, reducing or eliminating capacity in any of the technologies used”, explained David Mesonero.

In addition to the ability to customise the system, which leverages its knowledge of the wind value chain, Gamesa will also offer a turnkey offgrid solution, i.e., it will build, commission, operate and maintain offgrid facilities.

This foray into the offgrid segment falls under the scope of the company’s interest, as expressed in its 2015-2017 Business Plan, in exploring business opportunities which complement its traditional wind business – such as solar and offgrid power – and could add value from 2018.

Note that the company has some prior experience in this segment: back in 2007, it installed a facility in the Galapagos Islands (Ecuador) which combines three diesel generators and three wind turbines.

Axpo Iberia S.L. has signed an agreement with Palma Cathedral for the supply of green energy to the various installations in the most iconic building in the Balearic capital. Popularly known as ‘La Seu’, the building was declared an Artistic Historical Monument in 1931 and its rose window is the largest in Europe. The second largest Gothic cathedral in Europe, it is also known as ‘the cathedral of light’ and welcomes nearly 900,000 visitors annually. In addition, to promote efficient use and energy savings at the installations, the consumption of green energy has become a key principle for the prudent and sensible use of energy. “Axpo manages the largest portfolio of renewable plants in Spain, which allows us to offer 100% renewable energy to all our customers, and to help them meet their sustainability commitments,” said Ignacio Soneira, Managing Director of Axpo Iberia.

The decision taken by the management of Palma Cathedral is consistent with their commitment to reducing the environmental impact of their activities, by means of sustainable solutions which contribute to the conservation of the planet. “Palma Cathedral has an established power-management policy, in line with the concern over environmental issues and the consequences of climate change recently expressed by Pope Francis I in his encyclical Laudato Si” , commented Jose E. Capote, head of Palma Cathedral Council. “In order to contribute to the mitigation of this concern, an Energy Management System has been implemented based on the standard ISO 50001:2011 so as to continuously improve the management of energy consumption and to reduce greenhouse gas emissions”, he added.

Palma Cathedral has chosen one of the indexed contract types offered by Axpo, enabling more efficient management of its consumption by paying the real hour by hour market price of electricity, benefiting from consumption at times of lowest energy cost.

Since its entry into the Iberian market in 2002, Axpo Iberia has gradually expanded its lines of business in Spain and Portugal, now covering a wide range of services: marketing of electricity and gas; energy management for special regime producers; power generation control and load dispatching center (CECOGEL); structured products and trading in electricity, biomass, and CO2.
