Dubai Electricity and Water Authority (DEWA) has successfully launched its second nanosatellite DEWA SAT-2 aboard the Falcon 9 rocket of SpaceX from Vandenberg Space Force Base in California, USA. The nanosatellite was designed and developed by Emiratis at DEWA’s Research and Development Centre, in collaboration with NanoAvionics in Lithuania. DEWA SAT-2, a 6U nanosatellite, features a high-resolution camera (4.7 metres) that will be used for Earth observation missions. The high-resolution camera provides continuous line-scan imaging in seven spectral bands from an approximately 500km orbit. The new satellite is also equipped with Infrared equipment to measure greenhouse gases.
His Excellency Saeed Mohammed Al Tayer, MD and CEO of DEWA, said DEWA’s Space-D programme, which was launched by His Highness Sheikh Mohammed bin Rashid Al Maktoum, Vice President and Prime Minister of the UAE and Ruler of Dubai, in January 2021, aims to improve the operations, maintenance and planning of DEWA’s networks through nanosatellites and remote sensing technologies. The programme also seeks to train Emiratis specialised in the use of space technologies in electricity and water networks.
Al Tayer noted that DEWA aims to use nanosatellite technology to support its cloud computing network, thereby enhancing the digitisation of energy and water networks. The objective is to raise the efficiency and effectiveness of planning, operation and preventive maintenance of the production, transmission and distribution divisions, as well as smart grids, power stations, and EV charging stations. This approach is expected to reduce costs and improve the investment of DEWA’s assets. Additionally, this will help develop use cases that contribute to upgrading the utility sector worldwide.
The combined use of DEWA SAT-2 images and IoT measurements from DEWA SAT-1 will enable DEWA to improve the operational performance of power generation and water desalination plants by providing accurate estimates of seawater temperature, seawater salinity, detection of red-tide, as well as fog monitoring and forecasting.
DEWA launched DEWA SAT-1 in January 2022, becoming the first utility in the world to use nanosatellites to improve operations, maintenance and planning of electricity and water networks. The nanosatellite was designed and developed at DEWA’s Research and Development Centre at the Mohammed bin Rashid Al Maktoum Solar Park.
