Dubai Electricity and Water Authority (DEWA) announced on Sunday that its Smart Grid Station (SGS) in Al Ruwayyah was inaugurated by Sheikh Ahmed bin Saeed Al Maktoum, Chairman, Dubai Supreme Council of Energy.

The Dubai utility said in a press statement that the SGS uses a variety of smart grid technologies to generate power through renewable sources, maximise energy efficiency through real-time monitoring and control systems, and also allows for the reduction of loads, especially at peak times; peak shift, and the reduction of water consumption.

According to the statement, the SGS comprises a 200-kilowatt (kW) photovoltaic solar power system; a 9-kilowatt (kW) wind turbine; and a 500-kilowatt hour (kWh) lithium-ion battery energy storage system.

The station also includes over 2,000 sensors based on the Internet of Things (IoT) technology, and smart meters to monitor power and water demand data in real-time for the purpose of improved energy and water management, with the potential to reduce demand when required by eliminating non-critical loads through smart lighting, smart power outlets, and smart air conditioning system.

The statement noted that the SGS is also integrated with a smart chiller system through a Building Management System (BMS), and a 100-tonne thermal energy storage system (TES), which stores surplus cooling energy to be used when required, thereby reducing the demand on the chiller system.

DEWA signed a contract with Korea Electric Power Corporation (KEPCO) in November 2015 for the development of the SGS at its green vehicle workshop in Ruwayyah.
