High River Solar – EMF Report 1

1.0 Introduction On behalf of High River Energy Center, LLC (High River Energy Center or the Applicant), TRC Companies has performed an engineering assessment of the Electric and Magnetic Fields (EMF) associated with High River Energy Center (the Project). This study was performed on the rigid bus interconnection between the Project’s proposed collection substation and the adjacent point of interconnection (POI) switchyard, both located on land within the Project Area. An EMF Study was also performed on the portion of overhead line to be installed from the POI switchyard to the existing Stoner – Rotterdam #12 115 kV transmission line. No EMF calculations were performed on the 34.5 kV collection system. The proposed interconnection consists of a rigid bus that will connect the proposed High River collector substation to the new POI Switchyard that will be owned by National Grid in the Town of Florida, NY. Due to the proximity of the collector substation to the proposed utility substation, rigid bus is proposed for the interconnection between the two facilities. From the utility substation two overhead lines will run approximately 500 ft northeast to connect to the existing National Grid Stoner – Rotterdam #12 115kV overhead transmission line. These lines will consist of 795 kcmil 26/7 “Drake” Aluminum Conductor Steel Reinforced (ACSR) conductor which is National Grid’s Standard conductor for 115 kV lines.

This study evaluated the future EMF levels at 60 Hertz power line frequency produced by the proposed rigid bus interconnection circuit and the overhead transmission line connections. This study summarizes the future, or post-construction, calculated EMF generated from these two locations. The pre-construction EMF field generated in these locations is zero, as no electrical equipment currently exists at the location. The post-construction EMF levels for the rigid bus interconnection were calculated using the geometry of the interconnection and the electrical parameters which will exist when the Project is operating at peak power generation levels and the maximum average annual load estimated to occur on the interconnection. The post-construction EMF levels for the

transmission connection were calculated using the geometry at the locations of New Pole 1 and New Pole 2 as shown in Figure 1 above and the winter normal line rating of the 336.4 kcmil ACSR “Merlin” wire utilized on the existing Stoner – Rotterdam #12 line. Note that the existing wire on the line is a smaller conductor than the 795 kcmil conductor that will be utilized for the proposed transmission connections. The solar panels associated with the Project will generate direct current (DC) power. Multiple solar panels are interconnected and are connected via cables to inverters which convert the DC to alternating current (AC) power. As shown on the Preliminary Design Drawings in Appendix 11-1 of the Application, there will be inverters centrally located throughout the Project Area. Transformers associated with the inverters will step up the voltage to 34.5 kV. The output of the inverters and associated transformers will be collected via two 34.5 kV underground collection feeders which will connect to the proposed collector substation. The proposed collector substation facility will step up the solar facility voltage from 34.5 kV to 115 kV. A review of ratings and the layout of the Project components demonstrate that there will be no significant EMF effects at the Project Area boundaries.

2.0 Technical Approach EMF levels were calculated using Bonneville Power Corona & Field Effects Ver. 3.1 Software. A computer simulation was developed to calculate the post-construction EMF levels at the typical cross-sections. 2.1 Interconnection Bus The EMF calculations did not consider any energized sources other than the 3-phase rigid bus interconnection. In performing the EMF calculations, the following typical parameters were used:

Bus outside diameter;

Bus spacing and height above finished grade (see Figure 2 and Figure 3 below);

Power generation levels of the facility; and,

Voltage of the facility.

4.0 Conclusions The maximum calculated electric field level along the Project’s collection substation and the POI switchyard is 1.873 kV/m located 15 ft from the centerline. The maximum calculated electric field level at the edge of the Project Area is 0.015 kV/m, located 175 feet north of the centerline (see Table 2 and Figure 5). The maximum calculated electric field level on the transmission connection is 1.225 kV/m at the approximate location of the structures (see Table 4 and Figure 7). The study reveals that the calculated electric field levels at the edge of the proposed right-of-way located 75 feet from the centerline, is 0.04 kV/m and are less than the 1.6 kV/m maximum electric field level permitted at the edge of a transmission right-of-way in New York occupied by a major transmission line per the New York State Public Service Commission (NYS PSC) Interim Guideline. The maximum calculated magnetic field level along the Project’s collection substation and the POI switchyard is 105.08 mG located at the centerline. The maximum calculated magnetic field level at the edge of the Project Area is 1.66 mG, located 175 feet north of the centerline (see Table 3 and Figure 6). The maximum calculated magnetic field level on the transmission connection is 74.99 mG located 35 feet away from the centerline between the structures (see Table 5 and Figure 8). The study reveals that the calculated magnetic field levels at the edge of the nearest proposed right-of-way, located 75 feet from the centerline, are 35.35 mG, well below the 200 mG maximum field level permitted at the edge of a transmission right-of-way in New York occupied by a major transmission line as per the NYS PSC Interim Guideline. This report demonstrates that the EMF levels associated with the interconnection between the Project’s collection substation and the POI switchyard and the POI switchyard and the existing Stoner – Rotterdam #12 line are within established guidelines. Additionally, the solar panels installed as part of the Project will be a minimum of 14 feet from the Project Area boundaries. EMF from individual panels represent outputs consistent with household EMF levels. The setback associated with the Project design contribute to minimize static EMF from these DC sources at the Project Area boundaries.
