Renewable Energy Resources in Oman 6.2.3 Solar thermal plant, 20 MW The economic calculation for the Solar Thermal plant in below table 6.7 is valid for a plant without storage and with data from Ref /15/ and Ref /22/. There are a number of plants under construction which includes storage of up 15 hours capacity. The solar TRES plant mentioned in chapter 5 (fig 5.9) is planned to generate 96 GWh of electricity per year with an investment cost not much higher than in the example below. Table 6.7 Solar Thermal Plant - 20 MW Item Value Comment Capacity 20 MW Collector Area 130 000 m 2 Capital Cost 72.5 Mill USD 3.6 USD/W, includes connection cost to transmission system O&M Cost 0.8 mill USD per year Solar insolation 2 200 kWh/m 2 Power Production (Useful) Lifetime 35 GWh/year 25 years Discount Factor 7.5% Long Run Marginal Cost 207 USD/MWh The economic result depends on the lifetime of the plant, which is estimated to 25 year. Assuming a life time of 40 years, and a discount rate of 4% the economic cost of Solar Thermal Plane is 126 USD/MWh. 6.2.4 Small off-grid solar PV -diesel system, 10 kW The system is configured with one10 kW diesel engine, 2 kW PV and 50 batteries with a storage capacity of about 25 kWh. The key figures in the cost calculation are shown below in Table 6.8. Table 6.8 10 kW off grid solar PV system Item Value Comment Capacity Capital Cost 0.01 MW 32 800 USD Capital Replacement Cost 1900 USD per year Lifetime varies per item O&M Cost Power Production (Useful) 4 600 USD per year 78 MWh year Lifetime 15 - 25 years Varies by item in the system Diesel Price 146 Baiza per Litre Discount Factor 7.5% Short Run Marginal Cost Long Run Marginal Cost 127 USD/MWh 245 USD/MWh Page 100 of 134 .
Renewable Energy Resources in Oman The Long Run Marginal Costs are estimated to 245 USD/MWh. Approximately 5% of the electricity produced by the system will be solar. 6.2.5 Grid connected 20 MW wind farm Method and Assumptions The following Table 6.9 shows the assumptions regarding the construction costs for a 20 MW wind farm in Oman. It has been assumed that the construction costs are independent of the wind farm site.

Like for the other plants the used discount rate is 7.5% p.a. Page 101 of 134 .
