1. A Brief History of DEWA

In 1959 His Highness Sheikh Maktoum bin Rashid Al Maktoum established two separate companies to cater to the electricity and water distribution needs of the emirate of Dubai .However, the decision was made in 1992 to merge these companies into one entity to be called the Dubai Electricity and Water Authority (DEWA).

Since its establishment 21 years ago, DEWA has evolved to become a world-class energy provider with a clearly articulated vision and mission (see Figure 1).

1.1 DEWA Organizational Structure

      There are different types of organizational structures that can be classified using different criteria. These organizational structures can be adopted by different organizations. Decisions on the specific organizational structure that an organization adopts are from the senior management, they also determine the natural reporting relationships and chain of command. These decisions are determined by the objectives and strategy of the organization. These reporting relationships can be both vertical as well as horizontal. These structures help in coordination, controlling and act as a tool for motivation of employees toward the organizations goals.

      DEWA is composed of 10 divisions, all of which incorporate several departments (See Figure 2).  For the purpose of fulfilling the requirements of my internship program, I was assigned to the Power Transmission Planning department, which is a part of the Power and Water Planning division. In more precise terms, the Power Transmission Planning (PTP) department is responsible for managing the medium and long term strategy of Dubai’s energy needs.  The particulars of my duties within this department are discussed in the following section

                                                                         5

          For DEWA to be effective there has to be an effective organizational structure in place. An organizational structure is therefore a typically hierarchical arrangement of lines of authority, communications, rights and duties of an organization. In other words it is a form of structure that determines the hierarchy and reporting structure in the organization. In lay mans language it is referred to as organizational chart. An organizational structure, DEWA,  that is well thought out and strategic helps support good processes for communication and also clarifies the lines of authority that are in existence and reporting relationships so that to assure the work processes flow in a defined process.

           There are various organizational designed that can be found within the different organizations. The geographical aspect of an organization design implies to what extent the organization operates. This can be local or international. The organization in question is a local based one and hence the need to adopt a simple organization structure that will be functional within the local area. The functional design of the organization in DEWA is simple with just the basic functions of an organization in place, these include human resource, marketing, finance, operations that include production process and service provision. This calls for the adoption of a functional organizational structure that will effectively deal with these specific functions of the organization. The customer base of DEWA is just local for the organization and hence the delegation of a local customer department which is part of the functional organization structure to deal with these customers. The marketing channels for the organization are local the suppliers and distributors are within the same region. The establishment a simple marketing department is just but enough to serve the marketing for the products. Departmentalization in DEWA is an essential organizational design that has a great influence in the choice of the organization structure, the organization of choice has many departments within it and this paves way for the adoption of a

functional organization system since the functional departments will be included in the organization structure.

1.2 Internship Duties

During the course of my internship duties, I was assigned to two sections within the PTP department, namely the System Planning and System Studies sections (see figure 3)

1.3 Power Transmission Activities (PTA)

The activities of the System Planning section include the following:

1) monitoring power demand growth, gather and analyze growth data, anticipate demand growth and produce short and long term yearly forecast update;

2) Production of yearly update of Power System Master Plan.

3) Planning for new sites and corridors.

4) Issuing project parameter reports to Projects and Engineering Division.

5) Reviewing and evaluating new technologies to determine their relevance to DEWA’s goals and objectives.

6) Develop study models for DEWA system.

7) Conducting studies to evaluate and analyze the performance of DEWA’s power generation and distribution systems.

8) Formulating clear plans for the refurbishment and maintenance of various types of hardware/heavy duty equipment and built structures.

9) Study requirement of import/export energy through interconnection.

10) Liaising with major private sector property developers (such as EMAAR) in order to ascertain their future energy needs and make appropriate medium and long-term plans.

Specifically, my internship project involved the writing of a manual, known as Project Parameter Report (PPR), which provides detailed guidelines concerning the procedure for connecting a new substation to the Dubai Electricity grid.

1. PROCEDURES FOR PREPARING A PPR

        In order to acquaint me with the procedures for preparing a PPR, my DEWA line managers  explained the importance of the PPR: essentially, the PPR should be a comprehensive technical specification document for the construction and equipping of a new electrical substation. It must be noted that PPR documents are highly confidential and therefore it is not possible to discuss the specific details of the PPR which I prepared. However, there are certain standard DEWA organizational procedures in relation to PPR preparation which are as follows:-

      (i) The most critical information needed when planning a new substation is the projected electrical consumption requirements (for at least a five-year period) of the targeted area. In order to gather such information, it is necessary for all real estate developers (doing both commercial and residential construction) to submit their projected monthly power consumption requirements along with building plans indicating dates when it is expected that the real estate development will be completed. The DEWA System Planning Section will then collate these submissions to produce a report detailing the overall projected power requirement needs of the targeted area.

     (ii) The report specifying the power requirement needs is then submitted to System Planning engineers who will….each engineer in a system planning section will study a case and he will but option for how to connect a new substation so a report its include many options 5 to 6 options from different engineers and then they will meet together with a manager of a system planning to choose the best option for connection . a report will include all the options and they will write the reason for not selecting each option like for example option 1 : the connection for this substation is non-optimal due to its high financial burden other reason also heavy loading also this connection suboptimal in terms of maximizing the use of the installed 132kv cable assets within the loop. First in a report they will write the options and the reasons for not selecting this option then in a recommendation they will write about the best option that they select. After they will finish a report they will send it to the second sections that is System Studies section a system study section will study the best connection that they select by using PSSRE system ( Power system studies) this system is simulating for DEWA network so a system studies engineers will add this new substation with the connect that system planning are selected to a DEWA network and they will see how it will affect and also the will do some studies for example two studies Short circuit studies and Load flow studies and the will write their comments about this connection and if they will see that this not a best one will suggest to a best connection then they will replied to a system planning and then after selecting the best connection this report will be ready to start a work and they will start building the new substation with the best connection .

What include in a report is

Summary

Background about the project.

The proposed development solutions

System performance

Alternative Options Considered

Recommendations

Please only rewrite what I wrote in Purple colored to write it in steps and this all about a report or tasks that I send it to you only write it in a good way please.

2.2 Acquiring the Skills Needed for Preparing the PPR Report (Task)

Prior to the production of the PPR, it was necessary for me to acquire certain skills concerning the procedure for conducting on-site inspections. These skills included (i) techniques for estimating equipment and material costs for outfitting a sub-station; (ii) technique for analyzing the type and working functionalities of the machines.

Conclusion

A good knowledge about the system and experience is important in determining optimum solutions under various situations which entail technical, environmental and economical as well as social-economic parameters. It is important to stimulate any network configuration and analyze its behavior. In this regard the following is recommended to be a better connection.
