Actually there are 7 gas fired power generation plants in Oman. All of them are backed-up by diesel power generation. The installed capacity amounts to 3600 MW. New capacity is planned for Salalah with 400 MW for Dhofar Power Company.
Regarding the development of Al Duqm, the connection to the main grid is under planning and shall be finalized end of 2009 till 2010. Along with the growing demand of electric power in Al Duqm a local power generation plant will probably be implemented. Future plans are to connect Dhofar grid with MIS via the existing mini-grid of PDO.
Eng. Saleh Al-Rasdi mentioned about potential for renewable energy in Salalah with wind energy and on other locations with hydropower plants. Due to the relatively low electrical power consumption in the winter period the balance capacity of the installed power generation plants could be used to pump water up in dams. Power consumption in winter period decreases to 1/3 of the peaks in summer period. The stowed water could thus power hydropower turbines in the hot season.
For detailed meeting it was decided to meet with Mr. Alan Davis (Planning &
Pricing Manager).

4. Oman Waste Water Company
Eng, Omar Khalfan Al-Wahibi, CEO Date: 25.09.07 at 13:00 h
A. Basis for the meeting Subject: Biogas
1. Waste management structure 2. Waste management documents
3. Current waste accumulation, quantity development and composition 4. Which type of industry/consumers produce the waste water
5. Present mode of handling of waste water: how is the waste water transported to the waste water plant, what is it used for?
6. What are the expenditures for handling the waste water?
7. Have there been any considerations for utilizing waste water for biogas production?
8. Attitude to include renewable energy supply in the plans B. Comments received
OWWC is only responsible for waste water in the area of Muscat. All the rural areas are under the responsibility of the Ministry of Regional Municipalities. A third company is responsible for Salalah. Solid waste is managed by other authorities. The infrastructure of waste water management is under development. It is targeted to reach 80% coverage in 2013. The today’s yearly amount of waste water is around 43,000 m3. The activities are actually concentrated on the higher populated areas.
There is no biogas production due to small amount of waste. Waste is partly used for fertilizer production. A new composting facility shall start operation in 2010. The capacity was not communicated. The yearly operational cost of OWWC amounts to 2.6 m USD.
The attitude to renewables was very positive. The shortage of gas should especially taken into consideration when talking about renewables.

4. Implementation and operation costs for the systems 5. Attitude to include renewable energy supply in the plans B. Comments received
ROP is very interested to implement renewables in their power supply concept. BOT projects are the most favourable projects in this regard. They mentioned that solar could be still too expensive for feed-in solutions compared to the gas generated electrical power in Oman which is subsidised.
ROP purchases electric power on a basis of 50% of the official tariffs in Oman.
They are interested to investigate more on the feasibility of wind power generation (for example for the island of Masirah).
ROP is only looking to supply power for there own buildings like prisons, academies etc. The average power demand of these buildings lies between 500 and 1000 kW. The new prison next to Nizwa (name???) is planned to have 1.8 MW. ROP is ready to invest in renewables even if the power production is more cost intensive than comparable gas fired power generation.
The amortisation period can be up to 20 years.
ROP asked for the delivery time of one 5 MW wind power station and of smaller systems with around 600 kW.
ROP operates one solar power unit on Daymaniyat Islands for radio base and radar stations with installed capacity of 2.0 kW.

1. Attitude to include renewable energy supply in the plans B. Comments received
MRM operates around 300 trop-off sites for domestic waste. A new landfill is planned for Sur with the local Municipality of Sur. A similar project will be established in Adan area in 2009 (Dakhla region). 8 major locations with 7000 m3/day are: Sur, Ibra, Sumail, Nizwa, Ibri, Saham, Rustakh, Khasab and Barka.
The waste treatment plants in all other cities (approximately 75) are very small and have capacity between 120 and 200 m3/day.
Data about the food industry, slaughter houses etc. have to be collected from the Ministry of Industry and Commerce. Further information about waste of farms, numbers of animals and so on can be collected from the Ministry of Agriculture.
Industrial waste is not under the responsibility of MRM.
Regarding the handling of waste, the legislation for OWWC and MRM are identical.
Regarding landfill no reports are available and no studies are done right now.
Positivity about renewables. Eng. Abdul Hakim Al-Zadjani mentioned to visit the oldest wind powered water pump in Oman in Matrah (Muscat) which was installed between 50 to 60 years ago.
