UAE - Dubai EXPO 2020 - Design and Construction Supervision Consultancy Services
In 2020, the UAE will host the Expo 2020 in Dubai, which site is located adjacent to Al Makthoum International Airport and between Abu Dhabi International Airport and Dubai International Airport. The site covers a total area of 4.38 km², and will have the capacity to accommodate up to 300,000 visitors per day and a total of 25 million visitors.
The sustainability and renewable energy mix based concepts in this project cover various aspects related to rental and/or temporary access to building roofs for installation of Solar PV panels (BIPV, BAPV) during Expo 2020 Dubai's six-month event period and most flexible concepts for renewable energy systems integrated into other projects. The portfolio of renewable energy assets considered in this project contains solar PV, Waste-to-Energy anaerobic digestion, wind energy, solar hot water, fuel cells, energy storage, solar cooling, and/or other future RE technologies, e.g. transportation concepts for e-mobility to be deployed along with a smart grid infrastructure.

Maldives - Sustainable Energy Development for the outer islands
Maldives has 194 inhabited islands, each of which is electrified with its own diesel-powered mini grid system (total installed diesel generation capacity of 100 MW + 100 MW on the tourism islands). In 2012, the cost of diesel power required government subsidies of more than 40 million US$.
On the other hand, Maldives has significant renewable energy resources, particularly solar and - to a minor extent - wind energy. Given the cost of diesel, the Government initiated two programmes to extend the use of renewable energies in electricity generation. The present project covers the design, tendering, and implementation of hybrid solar / battery / diesel mini-grids on 166 islands, with a total of 25 MW solar (PV) power, a total of 8 MWh storage capacity and 44 diesel power plants. Systems are roof-top or ground-mounted and have a size of between 3.5 kW and 1,600 kW per system.

UAE - 11 kV Feeder Panels in some 132/11 kV Primary Substations in Abu Dhabi Island
22 (twenty two) 132/11 kV primary substations exist in Abu Dhabi Island. In line with ADDC's standards, the number of 11 kV outgoing feeder panels per substation is 48 (forty eight). This standard design was adopted from the year 2005. However, most of the primaries commissioned prior to 2005 have less than 48 (forty eight) 11 kV outgoing feeders.
With the objective to install additional 11 kV outgoing feeder panels, ADWEA commissioned a study on 12 selected existing 132/11 kV primary substations in Abu Dhabi Island and the implementation of the recommendations for network augmentation at these substations.
The scope of these consultancy services included study, design, preparation of tender documents, tendering and supervision of the supply, the installation and the commissioning of 11 kV outgoing feeder panels at some of the above primary substations. The aim was to utilize the available spare FIRM capacity to serve new customers / connections, to reinforce the existing network and also provide panels for connecting the battery energy storage system (BESS).
