storage

Ingeteam has began the year 2016 by commissioning the first hybrid plant in Brazil to be connected to the public grid, combining PV energy and battery storage. The power generated by the rooftop PV panels (90 kWp) is stored in a sodium battery bank (276 kWh) controlled by the Ingeteam battery inverter. The whole system is managed by the Battery System Controller developed by InGrid.

The grid-tied system incorporates a battery inverter to operate in self-consumption mode. Therefore, the priority is to keep the batteries charged with the energy sourced from the PV plant. In this way, during a grid outage, the system can move to off-grid mode in less than 20 milliseconds, using the batteries to provide the necessary power.

Although this plant, located at the headquarters of the Brazilian army in Brasilia, is the first of its kind in Brazil, the collaboration between the companies taking part in this project is expected to continue in the near future, in remote areas with no grid access or in situations with a weak or unstable power supply.

The Ingeteam supply

In addition to the commissioning conducted by an Ingeteam engineer shortly before Christmas, Ingeteam also supplied an INGECON SUN STORAGE 125 kW three-phase battery inverter for this project.

This is the second project in which this new battery inverter is installed, as it was launched into the market by the end of 2015. This equipment is responsible for the generation and management of an alternating current (AC) network, thereby guaranteeing the correct balance between generation, consumption and energy storage. Moreover, this INGECON SUN STORAGE inverter can operate in both stand-alone or grid-connected modes, allowing different strategies such as self-consumption, back-up or grid support. This inverter is available with an AC power ranging from 60 to 250 kW.

Furthermore, the Ingeteam supply for this plant also included five INGECON SUN 3Play PV string inverters.

A new groundbreaking report from IRENA offers clear guidance as how to advance storage systems as part of the infrastructure for a sustainable energy future. Renewables and Electricity Storage, a report released on the sidelines of IRENA’s ninth Council meeting, prioritises 14 action points across five priority areas in which governments and industry can work together to facilitate the development of policies to store renewable electricity.

The report is part of IRENA’s REmap 2030 programme that is committed to doubling the share of renewables in the electricity sector to 45% by 2030. To do so, an estimated 150 GW of battery storage and 325 GW of pumped storage will be needed, making storage a vital element in the expansion of renewable energy. This article is based on the abovementioned report.

With solar and wind installation breaking new records each year, countries with ambitious plans for these renewable power generation technologies must consider the best ways to integrate variable renewables into the grid. Electricity storage is a key option available to manage variability and to guarantee a reliable, round-the-clock supply. Declining costs and improving capacities have made batteries and other storage technologies increasingly practical for upgrading existing power generation systems. Read more…

Abengoa has been selected by the Ministry of Energy of the Chilean Government and Corfo (Corporación de Fomento de la Producción) to develop a 110 MW CSP plant using tower technology with 17.5 hours of thermal energy storage using molten salts. The project will be located in the Atacama Desert, the region with the highest solar radiation concentrations in the world. It will be the first solar-thermal plant for direct electricity production in South America.
Abengoa’s project won the international tender launched by the Chilean Ministry of Energy and Corfo to construct the first Concentrated Solar Power plant in Latin America. As part of this tender, the project will receive direct subsidies from the Chilean Government and the European Union, as well as financing from the Inter-American Development Bank, KFW Kreditanstalt für Wiederaufbau, the Clean Technology Fund and Canadian Fund.
The solar plant will also have a pioneering thermal storage system with 17.5 hours of storage that has been designed and developed by Abengoa. This makes the technology highly manageable, enabling it to supply electricity in a stable way, 24 hours a day, responding to all periods of electricity demand.
Abengoa’s new project will be located in the commune of María Elena in the Antofagasta region, northern Chile. The project forms part of Chile’s national renewable energy program, intended to provide Chile with a cleaner energy future, while also promoting its economic development and reducing its dependency on coal and natural gas. Chile has set a target to produce 20% of its electricity from clean energy sources by 2025.
Abengoa’s project in Chile will prevent the emission of approximately 643,000 tons of CO2 into the atmosphere every year. Furthermore, the construction, operation and maintenance of this plant will act as a catalyst for regional socio-economic development, creating a large number of direct and indirect jobs for the construction, development, commissioning and operation of the plant as well as a network of services that will promote economic growth in the country. Construction of the project is due to start in the second half of 2014.

49.9 MW and thermal storage in a new generation plant

The OHL group’s industrial division is in its final phase of executing the construction of the Arenales CSP plant, and is currently in possession of the installation’s definitive start certificate. The CSP plant uses parabolic trough collector technology, has 49.9 MW of capacity, and is just waiting for the final jobs to be completed before coming on line by the end of this year.
