The State of Qatar has begun a pilot project to store grid-scale power using a 1MW/4MWh lithium-ion energy storage system— a first for the state that relies completely on power from gas and oil.
Power utility The Qatar General Electricity and Water Corporation (KAHRAMAA) launched the QR 10 million ($2.8 million) project in cooperation with Al Attiyah Group and Tesla.
Energy storage units have been installed in the Nuaija station to deliver off-peak power supply, improve the network voltage and load shedding at the station.
Batteries are connected to a substation, which in turn is connected to the Nuaija station on a voltage of 11 kV; they are controlled by the Control Center of Distribution Control Center.
Al Attiyah Group built and prepared the civil work and installed the equipment in the station in coordination with KAHRAMAA, while Tesla provided the batteries.
The power utility says the use of energy storage systems in power grids (batteries) was considered one of the ways to raise energy efficiency and enhance sustainability.
In a statement, it said: “The importance of the success of this pilot project lies in opening new prospects and avenues to engage in larger projects in the future by connecting them to some high-load stations in the network, and integrating them with our strategic projects for renewable energy, such as Al Kharsaah Solar Power Project.”
