Section 2. Facility Technology and Capacity
2.1 Technology Description
The Facility is a utility-scale, ground-mounted, single-axis tracking solar photovoltaic (PV) generating facility. The Facility employs single-axis horizontal tracker structures oriented on a north-south axis, which rotate east to west over the course of the day to optimize incident solar radiation on the PV module surfaces and maximize energy production. The tracker systems are designed to operate with a tracking range of approximately ±60 degrees from horizontal and include backtracking algorithms to minimize inter-row shading during low solar elevation angles.
The Facility's major equipment and systems include the following:
(a) Solar PV Modules. Crystalline silicon (c-Si) bifacial photovoltaic modules, commercially manufactured and certified to applicable IEC and UL standards (including IEC 61215, IEC 61730, and UL 61730). Individual module nameplate capacity is expected to be in the range of 550–600 Wdc. The total number of modules installed at the Facility will be determined during final engineering and procurement and is expected to be approximately 335,000–355,000 units.
(b) Single-Axis Tracker Structures. Horizontal single-axis tracker systems utilizing galvanized steel torque tubes and piers driven into the native soil. Tracker rows are arranged in a north-south orientation with east-west rotation. Tracker control is provided by independent row controllers communicating with a centralized tracker management system.
(c) Inverters. String-level and/or central inverter systems converting direct current (DC) output from the PV modules to alternating current (AC) suitable for injection into the medium-voltage collection system. Inverters shall be rated for an aggregate AC output capacity of not less than 150 MWac and shall comply with applicable IEEE 1547, UL 1741, and ERCOT interconnection requirements, including reactive power capability and voltage ride-through specifications.
(d) Medium-Voltage Collection System. An underground and/or overhead medium-voltage (34.5 kV) electrical collection system connecting the inverter stations to the project substation. The collection system is designed in a radial configuration with appropriate protective relaying, sectionalizing switches, and grounding systems.
(e) Project Substation and Step-Up Transformer(s). An on-site collector substation housing one or more power transformer(s) stepping up voltage from the medium-voltage collection level (34.5 kV) to the high-voltage transmission level (345 kV) for delivery to the Point of Interconnection. The substation includes high-voltage circuit breakers, disconnect switches, metering equipment (including revenue-grade metering), protective relaying, and associated bus work and structures.
(f) Supervisory Control and Data Acquisition (SCADA) System. A SCADA system providing real-time monitoring, control, and data logging of all major Facility components, including inverters, tracker systems, meteorological instruments, substation equipment, and communications infrastructure. The SCADA system enables remote operation and is capable of transmitting real-time generation data and status information to the Seller's operations center and, as required, to ERCOT.
(g) Meteorological Stations. A minimum of three (3) on-site meteorological stations equipped with pyranometers (measuring global horizontal irradiance and plane-of-array irradiance), ambient temperature sensors, module back-of-cell temperature sensors, wind speed and direction sensors (anemometers and wind vanes), and precipitation gauges. Meteorological data is recorded at intervals of not greater than one (1) minute and transmitted to the SCADA system.
(h) Balance of Plant. All other structures, equipment, and systems necessary for the operation of the Facility, including but not limited to access roads, perimeter fencing with wildlife-appropriate passage points, security systems, drainage and erosion control structures, communication lines and fiber-optic cables, spare parts storage, and an operations and maintenance (O&M) building.
2.2 Nameplate Capacity
The Facility's nameplate capacity ratings are as follows:
The DC Nameplate Capacity represents the aggregate peak power output of all installed PV modules under Standard Test Conditions (STC) as defined by IEC 61215 (irradiance of 1,000 W/m², cell temperature of 25°C, and air mass of 1.5). The AC Nameplate Capacity represents the aggregate continuous AC power output rating of all installed inverter systems and is the basis for the Facility's maximum injection capability at the Point of Interconnection.
The DC-to-AC ratio of approximately 1.30 reflects a deliberate overbuild of DC capacity relative to inverter AC capacity, a design strategy intended to increase energy production during sub-peak irradiance conditions and to optimize the levelized cost of energy over the Facility's useful life. During periods of peak irradiance, inverter clipping may occur, limiting AC output to the rated inverter capacity.
2.3 Estimated Energy Production
P50 Estimated Annual Net Generation: 350,000 MWh per year (post-losses).
The P50 estimate represents the annual energy production level that has a fifty percent (50%) probability of being exceeded in any given year and reflects the median expected annual energy output of the Facility after accounting for all applicable loss factors. Loss factors incorporated into the P50 estimate include, without limitation: module degradation, soiling, snow/ice losses (minimal for the Facility's location), inverter and transformer efficiency losses, medium-voltage and high-voltage electrical losses, tracker system downtime, grid curtailment assumptions, equipment availability, and other standard technical derating factors.
Basis of Estimate: The P50 Estimated Annual Net Generation is derived from an independent solar resource assessment and energy production estimate prepared by Heliograph Energy Consulting LLC, a nationally recognized independent energy consulting firm with principal offices in Denver, Colorado (the "Independent Resource Assessment"). The Independent Resource Assessment utilized a minimum of twenty (20) years of satellite-derived solar irradiance data cross-referenced with ground-based measurement stations, industry-standard PV performance modeling software (PVsyst or equivalent), and site-specific assumptions regarding terrain, ground cover ratio, tracker geometry, and electrical system design. The Independent Resource Assessment report is dated March 28, 2025, and has been provided to the Buyer and its technical advisors.
Total Contracted Volume (P50 Basis, 20-Year Term): Based on the P50 Estimated Annual Net Generation of 350,000 MWh per year and a PPA term of twenty (20) years from the Commercial Operation Date, the total estimated contracted energy volume over the life of the Agreement is approximately 7,000,000 MWh. This figure does not account for annual module degradation, which is expected to be approximately 0.40%–0.50% per year on a linear basis beginning in Year 2 following the Commercial Operation Date. Accordingly, actual cumulative energy deliveries over the full PPA term are expected to vary from this figure.
