Line Siting Committee Approves Ocotillo Project CEC

September 19, 2014

The Arizona Power Plant and Line Siting Committee granted a Certificate of Environmental Compatibility (CEC) for the Ocotillo Modernization Project at the end of a three-day hearing Thursday, Sept. 18.

The committee voted 6-0 with one abstention to approve the application from APS. As issued, the CEC authorizes construction of all five generation units planned for the project and includes standard conditions with which APS can comply.

Next, the Arizona Corporation Commission (ACC) will consider the CEC as part of an open meeting in November or December. The ACC has the authority to approve, deny or modify the CEC. will provide updates on the ACC schedule as it becomes available.

If the project gains regulatory approval and necessary permits, construction will begin at Ocotillo in 2016 and the five units placed in service in 2018. The two 1960s-era steam units currently in use will be decommissioned and removed. The plant’s two existing combustion turbines will remain in service.

Between adding the new units and removing the steam units, the site’s total capacity would go from 330 MW to 620 MW.
