IRENA report finds renewable power costs at parity or below fossil fuels in many parts of world
January 17, 2015
The cost of generating power from renewable energy sources has reached parity or dropped below the cost of fossil fuels for many technologies in many parts of the world, according to a new report released by the International Renewable Energy Agency (IRENA).
The report, “Renewable Power Generation Costs in 2014”, concludes that biomass, hydropower, geothermal and onshore wind are all competitive with or cheaper than coal, oil and gas-fired power stations, even without financial support and despite falling oil prices. Solar photovoltaic (PV) is leading the cost decline, with solar PV module costs falling 75% since the end of 2009 and the cost of electricity from utility-scale solar PV falling 50% since 2010.

A team from Fraunhofer Institute for Industrial Engineering IAO, together with Daimler AG and the Institute for Human Factors and Technology Management at the University of Stuttgart, is developing both the charging infrastructure and the energy management systems required to manage large fleets of EVs in a project called charge@work.
The aim of charge@work is to design a micro smart grid (MSG) capable of supplying the EV fleet with electricity produced exclusively from renewable sources. This year will see the installation of a photovoltaic unit and a small wind power system at the Fraunhofer Institute Center Stuttgart IZS, where up to 30 electric vehicles at a time can recharge at AC charge spots in the Fraunhofer Campus parking garage.
M5BAT 5MW storage system integrates multiple battery technologies
February 24, 2014
The E.ON Energy Research Center at RWTH Aachen University, E.ON electric utility company, battery manufacturers Exide and beta-motion and inverter manufacturer SMA Solar Technology AG (SMA) have joined forces to build the first multi-technology, modular large-scale 5MW battery storage system.
The unique feature of the M5BAT (Modular Multimegawatt, Multitechnology Medium-Voltage Battery Storage System) storage system lies in its modular design, which combines different battery technologies for optimal use. It consists of lithium-ion batteries to meet short-term demand; high-temperature batteries to supply power for several hours; and lead-acid batteries when the average discharge time is one hour or less.
