3 - Roof Top Project:

In 2013, Diam has prepared guiding frame for sustainable plan for RE in the Sultanate. The plan includes two main elements; short-mid-term plan and long term plan. The short-midterm plan aims to study the feasibility of using photovoltaic panel technology on the roof top. On the other hand, the long term plan aims to prepare comprehensive national energy strategy. The strategy includes utilizing renewable energy to cover the mounting demand on electricity, 8% to 10% annually, as result of residential and industrial expenditures in the sultanate.

The study has focused on the residential buildings; and concluded the possibility to produce 450 MW in Muscat governorate only and possibility to produce 1.4 GW if the technology been implemented in all governorates, which equals to 1.4 TWh in the year. Also, the study has presented the challenges of implemented this technologies such as high cost, high subsidy requirements, administrative and technical challenges and lack of local experience in this field. However, there are positive aspects in implementing this technology such as awareness and building capabilities in RE field, job opportunities in Small and Medium Enterprises. As mentioned in chart 1 below, the study has estimated that local sectors can participate by 35% of the total investment in this project.

Second: Local initiatives (studies):

1 - Feasibility study for using solar energy for generating electricity

A detailed study set up by Diam’s international consultant identified best locations for building solar power plants in the Sultanate out of 23 sites. The study confirmed that Sultanate has potential resources of solar energy which could be utilized for production of large capacity electric power. The study also identified and shortlisted best four locations- Adam, Manah, Ibri, AL-Khaboura- for future solar power plants which can have a capacity up to 200 MW .Adam and Manah have been recommended as ideal locations for such projects and preliminary environmental assessment was made. Also both locations have been used for establishing two meteorological plants for measuring solar energy data and other factors that affect plants design, in cooperation with the directorate General of Meteorology and Air Navigation and Oman Power and Water Procurement Company.

2 - National Energy Strategy Project:

Diam has assigned experienced consultant to prepare National Energy Strategy for the Sultanate and to establish general policies and trends for securing mid and long term demand on the energy. The study has been concluded in the second quarter of 2015.

3 - Wind Atlas:

In 2015, Diam concluded Wind Resources Atlas study for the level of wind across the Sultanate, and the main factors influencing wind energy projects, also for the determination of best sites to install wind masts to get bankable wind data for 4 selected sites.

The study has identified the 15 most promising sites for wind energy production in Oman, where wind reaches around 11 m/s in those sites. Among those favorable sites, Diam has identified four sites for further field, environmental and geographical analysis. In addition, the study has prepared a program that includes site locations and number of meteorological masts, technical specifications for the equipment’s and expected duration of data collection. Also, preliminary designs for the four locations have been prepared; for which, the data recorded from wind masts will be evaluated and compared to the data obtained from satellites to ensure data accuracy in those locations to match international investors requirements. This also will enable Oman to establish reliable numerical model for wind atlas.
