The renewable energy sector in the sultanate of Oman is considered as a national priority to supply the future energy demand. Most of the renewable energy projects in Oman are focused on primary energy production, and very few things are being planned regarding the use of the renewable energy resources in the final energy. One of the important means that can help in reducing the power demand and energy conservation is the use of solar water heaters in residential, public, and commercial building. Solar water heating, both in small and large scales, has a great potential as an important carbon trading projects. The sultanate of Oman is situated in the core of the sunbelt with an important potential of solar energy. Despite this important resources the uses of this renewable energy was limited to few and simple utilization as public lighting or park meter.
This paper investigates the benefits and the incentives of the deployment of Solar Water Heater (SWH) application in Oman through a preliminary case study in the residential district of Seeb. For the deployment of SWH a prototype of GIS-based decision support was designed based on different attributes related to households socio-economic factors, payback times etc. The GIS platform is very helpful to build different planning scenario to show how the SWH may be deployed at various levels (individual proprieties o city neighborhoods, or whole city projections).The RETScreen Clean Energy Project Analysis Software was used in this project. It was found that the annual energy saving for the Seeb district only is around 335,431MWh. This is equivalent to the annual energy produced by a 38.3MW power plant (generators). This means that, by replacing existing electric water heaters with SWHs, it will be possible to develop and expand future industrial applications without a need for constructing additional power plants in the short term.
The economic value of a domestic SWH system resides mainly in the amount of electrical energy it saves in addition to the degree of independence from conventional and polluting energy supplies it creates. Investing in SWHs in addition to constructing renewable energy power generation facilities would help satisfy the increasing demand in electric power and at the same time will reduce the GHG emission and create additional businesses and jobs.
Without the contribution of the Government in the investment of SWHs systems, the household owners will not find enough incentives to use SWHs in their households. It was found that a 50% sharing of the capital cost between home owners and the Government will benefit both parties and will produce profitable investments. Instead of paying subsidies for the electricity consumed by electric water heaters, the Government can invest in sharing half of the capital cost. It was found that the internal return rate ranges between 12.2 and 16.5% and the simple payback period is between 7 to 10 years which indicate a very good investment project for both householders and the Government. Therefore, the dissemination of the solar water heaters in Oman requires necessarily the contribution of the Government in order to make them. Instead of paying subsidies for the electricity consumed by electric water heaters, the Government can invest in sharing half of the capital cost.
In addition, it was found that such project has a big chance to qualify as a small-scale project and get approved by the Clean Development Mechanism (CDM) executive board. Therefore, CDM could also be used as an additional tool to foster the dissemination of the SWHs in Oman by providing more incentives for the Government to contribute in the initial investment. In other words, the clean development mechanism could help fostering the diffusion of the SWHs in Oman by providing certified emission reduction incentives to the Government.
