Taiwan AU Optronics (AUO) has launched an energy storage system (ESS) PowerLegato for commercial and residential use after being certified by German testing house TÜV Rheinland.

The self-claimed high density ESS provides a 48V lithium-ion battery produced in Japan and features over current, temperature, voltage and undervoltage protection. The system is available in 2.4kWh, 4.8kWh and 7.2kWh. It supports hybrid energy inputs and outputs and has the option to choose between PV DC and grid AC sources.

The system can also operate fully stand-alone off grid in Germany as well as the UK and can serve as emergency backup, according to the company. It also fulfills the qualifications for the Japanese S-mark incentive programme, allowing owners to receive subsidies.

According to AUO, the ESS can store 25% more energy per kg than its competitors.

The residential version entered the European market in 2013 and was awarded for its design by iF and Reddot.

German research centre Karlsruhe Institute of Technology (KIT) recently warned about safety issues of non-certified residential ESS.

India steps up power supply

Following widespread power outages in much of India last year, one region is taking matters into its own hands. The state of Bihar in the north east is expecting to see vast improvements to its domestic power supply, which is currently at a deficit of approximately 1000MW of power.

The state officials say grid supplies will improve by 600-700 MW this year, thanks in part to the Bahr thermal power station that will have two units each producing 660MW. This is expected to become operational in the second half of 2013.

To meet the power demand at present, the state is largely run on diesel generators because only 900MW is available from central power supplies. The capital Patna requires 400MW alone.

Apart from central supplies, the State is also on course to re-commissioning approximately 345 MW of own capacity through an extensive renovation and modernisation project in joint venture with NTPC, India’s largest power company. The units have been neglected for many years and require restoration to become useful.
