Dewa opens smart grid station in Dubai

The Dubai Electricity & Water Authority (Dewa) has opened a smart grid station in Dubai built in partnership with the Korea Electric Power Corporation (Kepco).
The station includes more than 2000 sensors based on IoT technology, and smart meters distributed throughout the facility to monitor power and water demand data in real time for 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.
The SGS comprises a 200kW photovoltaic solar power production system, a 9kW wind turbine and a 500kWh lithium-ion battery energy storage system, which stores energy for later use. The station is also integrated with a smart chiller through a building management system, and a 100tonne thermal energy storage system, which stores surplus cooling energy to be used when required, thereby reducing the demand on the smart chiller.
The construction of the SGS is part of Dewa’s efforts to implement technologies that link smart buildings for the exchange of information, improve energy and water efficiency, and optimise renewable energy in smart cities.
The various sections of the SGS use different smart grid technologies to generate power through renewable sources, such as solar and wind power, and increase energy efficiency through real-time monitoring and control systems. The SGS also allows for the reduction of loads, especially at peak times, peak shift, and the reduction of water consumption.
The components of the SGS highlight the smart city model through three concepts or systems: the smart office, smart building and smart factory. The concept is scalable and allows for the development of individual smart buildings, groups of smart buildings and smart areas, to ensure the efficient reduction of electricity and water consumption as well as carbon emissions, thereby becoming a smart city.
HH Sheikh Ahmed bin Saeed Al Maktoum, chairman of the Dubai Supreme Council of Energy, inaugurated the station, attended by HE Saeed Mohammed Al Tayer, CEO of Dewa.
“In line with our vision of being a leading sustainable innovative global corporation, we seek to shape the future of the energy sector locally, regionally and globally through government innovation by keeping pace with the Fourth Industrial Revolution and adopting innovative, disruptive techniques, such as artificial intelligence, IoT, robotics and 3D printing,” said Al Tayer.
The inauguration ceremony was also attended by HE Ahmed Butti Al Muhairbi, secretary general of the Dubai Supreme Council of Energy, and Jonghwan Lee, chief technology officer at Kepco.
Dewa signed a contract with Kepco in November 2015 for the development of the SGS at Dewa’s green vehicle workshop in Al Ruwayyah, Dubai. The contract was an outcome of the MoU signed between the two parties in 2014 to collaborate and exchange information on various topics, including smart grids, smart cities, demand side management, asset management, distribution automation, substation automation, advanced metering infrastructure, telecommunications, systems integration, IT infrastructure, renewable energy, electric vehicles, micro grids, energy sector databases, investment participation opportunities, performance benchmarking and joint workshops to raise awareness.
