Statement of Future Capacity Requirements 2008 – 2030 30
RSB Approved Version- 4 th August 2008 7. Site Location Commentary The primary purpose of this Statement is to identify the currently unplanned additional capacity requirements, as required under Articles 30 and 32 of Law Number 2 (1998), along with Article 34 of Law Number 2 (1998). These Articles also require ADWEC to purchase capacity by adopting the economic purchase method. In addition to the above well known ADWEC license requirements, ADWEC’s license also requires it to provide a site location commentary. This section fulfils that obligation. Existing Sites Some further potential for expanding capacity may exist at or close to the existing Fujairah, Umm Al Nar and Al Mirfa sites. Al Mirfa Of the five existing coastal generation / desalination locations (Shuweihat, Al Mirfa, Umm Al Nar, Taweelah and Fujairah) only one location (Al Mirfa) can definitively be further developed without any site constraints. It must be remembered that the existing Al Mirfa station would require some reconfiguration in order to make it better approximate the other cogeneration stations’ power to water ratios. Currently Al Mirfa has a small power to water capacity ratio. The possibility of expanding Al Mirfa, via adding just electricity capacity, has been examined by ADWEC in the past and an Request For Proposal (RFP) issued. Al Mirfa remains a good potential candidate on which to locate future capacity additions, given the current limited number of alternative locations. It is expected that the four open cycle gas turbines that are to be moved from the previously owned FEWA Al Zawra station will be relocated at the Al Mirfa station. This will increase the existing capacity at Al Mirfa by around 400 MW. Taweelah and Fujairah Two of the other existing coastal generation / desalination locations (Taweelah and Fujairah) are considered likely sites for additional capacity expansion, but further studies would be required to confirm this potential. In the case of the Taweelah site, ADWEC has reservations about further expansion of this site because of security of supply concerns. The Taweelah site already comprises capacity from the Taweelah A1, Taweelah A2, Taweelah B (TAPCO) IWPP stations and will soon be joined by the Taweelah A10 extension of Taweelah A1. Accordingly further large capacity expansions at Taweelah are considered imprudent by ADWEC. Despite these reservations, the projected large increase in demand may require that additional capacity be installed on this site. Further expansion of the Taweelah site, e.g. Taweelah C, would require additional study because of the high proportion of the sector’s capacity at this site and possible environmental constraints. It is considered probable that a new cooling intake / outfall Statement of Future Capacity Requirements 2008 – 2030 31
