The Qatar General Electricity & Water Corp. (Kahramaa), Doha, Qatar, has installed a 1 MW/4 MWh storage system at its 11 kV Nuaija station, PV Magazine reports.
The facility, built in partnership with Qatari conglomerate Al-Attiyah Group and US electric car maker and battery provider Tesla, is intended to store power during peak hours or when the station reaches maximum load as well as to improve network voltage.
The QAR10 million ($2.7 million) project was implemented in one year, with the Al Attiyah Group responsible for the installation of the storage systems and Tesla for providing the batteries.
“Kahramaa succeeded in completing the project ahead of schedule and beginning operations to benefit from it during the summer period, which is one of the highest periods of energy consumption in the State of Qatar compared to the rest of the year,” the utility said.
The project relies on Tesla Powerpack batteries, which are a scalable AC-connected storage solution for large-scale applications. According to the manufacturer, each Powerpack is a storage device with a capacity of 232 kWh and containing 16 individual battery pods, a thermal control system and hundreds of sensors that monitor and report on cell level performance.
