Arizona Public Service (APS), a utility subsidiary of Pinnacle West Capital (NYSE: PNW) is bringing into commercial operation 83 MW of photovoltaic solar plants by the end of 2013, which represents an investment of $375m.
Meanwhile, planning and procurement is underway for additional projects, PNW executives said in a Feb. 24 quarterly earnings conference call. Longer term, the company hopes to see up to 200 MW of utility-scale PV solar units owned by APS and in-service between 2011 and 2015, according to a slide presentation that accompanied the earnings call.
The commitments to date as part of the AZ Sun Program include:
** The 17-MW Paloma project that went online in fall 2011;
** The 17-MW Cotton Center online in fall 2011;
** The 11-MW Hyder phase 1 in fall 2011;
** The 5-MW Hyder phase 2 in early 2012;
** The 19-MW Chino Valley project in 4Q 2012;
** The 14-MW Luke Air Force Base solar project in 2013.
The utility also recently announced a request for proposals for solar developers and installers interested in developing an additional 14-MW project at the Hyder 2 complex in Yuma County, Ariz. APS hopes to see the new solar unit completed in 2013.
A bidder’s webinar on the 14-MW RFP will be held March 21. RFP responses are due April 30 and a contract agreement is expect in August.
With AZ Sun, APS is investing in the development of 200 MW of solar photovoltaic power plants across Arizona. APS is partnering with third-party developers and equipment providers to design and construct the facilities, increasing the opportunity for more developers to participate since project financing is provided by APS.
