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.

Guinea - Analysis of Electricity Supply solutions in the region of Boke

MASDAR is developing various projects in the Caribbean and other regions of the world and sourced experts to support the engineering and project management team. These support tasks are contracted separately in the form of so-called Work Orders (WO).

The Guinea Alumina Company (GAC) currently plans to extract about 15 million tons bauxite per year and to install approximately 30 MW of power capacity. The government and other key stakeholders are keen to develop power supply solutions for both the mining sector and the civil / private sector. In light of this, the present study defines the demand and potential power supply options for mining activities and for the surrounding communities.

The overall objectives of this assignment were to:

Prepare a demand study on the power requirements for the short, medium and long term in the regions impacted by GAC´s activities.
Develop options, incorporating both renewable energy and existing (and new) fossil fuel based generation for meeting the determined power requirements.

UAE - Establishment of Power Supply to Yas Island

In order to sustain the development of different regions of Abu Dhabi Island, ADDC, in collaboration with private developers, initiated several projects to expand the electrical network by adding primary substations and integrating them into the existing power network. Among other projects, the private developer ALDAR Properties PJSC embarked on the development of Yas Island to develop it into a major touristic, residential and commercial city located in the suburbs of Abu Dhabi Island.

Accordingly, a project was initiated to provide consulting services for the network expansion projects, both for temporary and permanent power supply, with the aim to assure the compliance of the installations with ADDC's / ADWEA's design guidelines, specifications and the overall project schedule.

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).
