Subject: Letter Report for Prosperity Photovoltaic Analysis

Dear Steve:

Black & Veatch has performed an evaluation of the Prosperity Switching Station for a solar photovoltaic (PV) system to be installed in conjunction with a battery energy storage system. We have determined an appropriate layout for approximately 600 kWp of PV, estimated annual output, and estimated capital cost.

The PV field layout was prepared using First Solar FS-272 Cadmium Telluride thin film modules as a proxy. The 2 foot by 4 foot modules are mounted three side by side so that each row has an aperture width of 6 feet. Ten modules are placed in series to form a string. Rows are 280 feet long. The field comprises 38 rows with a total of 8,170 modules, with a capacity of 592 kWp. Module area is 5,882 m2 of module area. The field would have room to add another row to achieve 608 kWp. Row spacing is 11.8 feet, with modules at a 20 degree tilt. Total array N-S dimension is about 450 feet. An aggregate road runs from Los Picaros Road around the proposed switching station site and along the east boundary of the PV field

The attached drawing shows the PV field layout. The land at Prosperity site generally slopes the wrong way (down to the north) at a 6 to 7 percent slope. We have assumed no terracing, but rather grading out undulations and leaving the slope. This results in additional shading losses compared to flat land. Terracing could result in reduced shading, but the additional space required between terraces, required for soil stability and to eliminate shading of the south row on each terrace, would result in greater land requirements in an already tight formation. The solar field area with a 5 foot perimeter takes up about 3.2 acres. The entire road for the facility is about 1.2 acres. Additional space for peripheral equipment would raise the solar facility requirements to about 5 acres.

We looked at row spacing of 11.8 foot spacing (a 50 percent ground cover ratio [GCRI, where GCR is the ratio of module to land area, excluding roads and inverter space) and at 13.3 foot spacing (44 percent GCR), and at 35 degree tilt and 20 degree tilt. Relative results are shown in Table 1.

We chose the 20 degree tilt, 3.6 m (11.8 ft) row spacing, with land slope at 7 degrees. It gives 98 percent of the annual output that zero slope would give, but zero slope could only be achieved by terracing and adding space (overall N-S dimension) between terraces. Going to the 4.07 m (13.3 ft) row spacing would increase annual output by about 0.7 percent, but would require over 500 feet N-S dimension. It is clear that the 20 degree tilt outperforms the 35 degree tilt.

Additional modules could be added by going to an irregular and non-contiguous field arrangemer although we don’t know how much of the land area will be required for the battery system.

Capital Cost
The capital cost estimate for the Prosperity PV facility is presented in Table 2. The cost includes t~ inverter and transformer; however, because these pieces of equipment may be included as part of ft battery storage system, they have been called out explicitly in the table, and can easily be remove Likewise, the nature of the project is such that some typical owner’s costs may be imbedded in the oven project, and therefore have not been included. These can be added at PNM’s request.

The overall cost estimate is about $2.4 million, or $4.1 lIWp. This cost assumes simple grading of ft site to remove vegetation and undulations, at a cost of about $10,000. Leveling the entire site would co about $116,000 (increasing the cost by $96,000 over the base cost). The cost of either two or thrE terraces would be about $81,000 (increasing the cost about $71,000 over the base case). Terracir would likely increase annual output by about 1 percent.

Annual Output Estimate
The annual dc output of the Prosperity PV system is estimated to be 1.1 GWh. The output was estimatc using PVSYST V4.37, based on Albuquerque, New Mexico, airport insolation and temperature dat Monthly dc and ac output estimates are presented in Table 3.

Should you have any questions, please feel free to call me at 913-458-7225 (913-220-5012 mobile) email me at StoddardLE@bv.com.

Very truly yours,

Hi Bill,

Thanks for link. Hope you are enjoying the NSA furor well after you started it.

Re: Freedom of Information Act (FOJA) Request
HQ 2014-00319-F

Dear Mr. Payne:

This is in response to your FOJA request sent to this office for response by the Department of Energy’s (DOE) Office of Information Resources. You asked for information regarding equipmen and installation costs at the Prosperity solar facility.

Enclosed are copies of documents located in the National Energy Technology Laboratory’s (NETL) files regarding participation in work at the Prosperity Switching Station. NETL was involved with the battery energy storage system at the site, not the solar (photovoltaic) portion; however, the enclosed documents are being sent because the work was performed under Cooperative Agreement No. DE-0E0000230 with the Public Service Company of New Mexico (PNM) which is linked to the Prosperity site.

Certain information was withheld pursuant to Exemption (b)(4) of FOIA including labor costs and cost share information.

Exemption (b)(4)
Information is withheld under Exemption 4 of FOIA (5 U.S.C. § 552(b)(4)) in order to protect trade secrets and commercial or financial information that are obtained from a person and that are privileged or confidential. The information is considered commercial because the companies submitted this information to DOE for the purposes of doing business with the federal government, The information was obtained from a person, because “person” covers a broad range of entities including corporations and associations. Nadler v. FDIC, 92 F.3d 93, 95 (2nd Cir. 1996). Information that is required to be submitted to an agency is confidential if its release is likely to cause either substantial harm to the competitive position of the submitter or impair the agency’s ability to obtain necessary information in the future. National Parks & Conservation Ass’n v. Morton, 498 F.2d 765 (D.C. Cir. 1974). The commercial information and business processes and strategies described in their applications were “required to be submitted” because they were a prerequisite to consideration for a financial assistance award.

Appeal Rights
As the FOIA Authorizing/Denying Official for NETL, I am responsible for making the above determinations with regard to your request.

DOE’s regulations provide that a denial of records, in whole or in part, may be appealed to DOE’s Office of Hearings and Appeals by writing to the Director of the Office of Hearings and Appeals, HG-i, Department of Energy, 1000 Independence Avenue, S.W., Washington, DC 20585, within 30 days of receipt of this letter. Both the envelope and letter must be clearly marked “Freedom of Information Appeal.” Additional requirements of an appeal are set forth in 10 CFR § 1004.8(b). Judicial review is available if the appeal results in a determination adverse to you in the district in which you reside or have a principal place of business; in the district where the records are situated; or in the District of Columbia.

Sandia National Laboratories engineers have been studying the most effective ways to se solar photovoltaic (PV) arrays -- a clean, affordable and renewable way to keep the power on. Systems are relatively easy to install and have relatively small maintenance costs. They begin working immediately and can run unassisted for decades.

But clouds could dim industry growth: What happens when they cover part of a solar PV array and cause a dip in output, how big is the dip and how can a utility company compensate for it? ...
