The Project is expected to produce 31,851 MWh annually and will support Holy Cross Energy’s (“HCE”) efforts to source 100% of their power supply from renewable energy resources by 2030. The coupling of battery storage technology will facilitate a firm renewable supply to HCE’s customers by allowing for solar energy captured during daytime periods of low load to be released in peak evening hours even after the sun has gone down. The Project is to be located at 1691 County Road 300, Parachute, CO 81635 on parcel 240935100136 owned by Larry A. and Karen K. Klebold. AES and the Klebolds have executed a binding Option to Purchase Agreement for up to 90 acres of said parcel contingent upon receipt of all permits, contracts, and approvals necessary to begin construction activity. AES High Mesa Solar is a shovel-ready energy project with site control, land diligence surveys, interconnection agreement and a signed Power Purchase Agreement with HCE in-hand. AES expects to conclude contracting, engineering, and ministerial permitting in early 2022 with construction starting immediately upon BoCC approval anticipated in June 2022, and commercial operation to be achieved prior to December 31, 2022, when the Project will begin delivering power to HCE’s distribution system. AES would be fully responsible for the development, installation, financing, administration, and long- term operation and ownership of the 10 MW AC / 20 MWh photovoltaic solar farm. AES appreciates this opportunity to present this clean energy solution to Garfield County and believes its proven track record as a leading Fortune 500 renewable energy company will provide Garfield County confidence in having a partner capable of responsibly and reliably providing clean energy to its residents. AES High Mesa Solar – Land Use Change – Major Impact permit application (10/22/2021) AES High Mesa Solar – Garfield County 4 Project Overview AES respectively requests review and eventual Board of County Commissioners’ approval for this Land Use Change – Major Impact permit application in order to supply 10 MW AC / 20 MWh of dispatchable renewable energy over a minimum of 20 years pursuant to the Power Purchase Agreement signed between the Project and HCE on 12/16/2020. Upon approval of this permit and reaching a construction ready status, the Project will file for a split per deed parcel with Garfield county, understanding that such a request should be ministerial given the resulting parcel will remain in the excess of 35 acres. The Project is to be located on up to 90 acres to be purchased from a total 340 acres of land off Richardson Road currently owned by the Klebolds and subject to the Option to Purchase Agreement. The project will interconnect to the distribution grid using an underground electrical conduit run from the proposed project area to the 24.9 kV line along the existing electrical easement that has already been upgraded by HCE, where new utility pole placements will meet the medium voltages cables as they surface and connect to overhead lines. Within the solar farm, there will be north-south rows of anti- reflective solar panels mounted to steel posts driven into the earth. All electrical components will be UL-listed, sourced from an approved Tier 1 vendor list maintained by AES and in compliance with the National Electric Code (“NEC”). The electricity generated is targeting interconnection into Holy Cross’ 24.9kV electrical distribution circuit that runs from the north of the property towards the Parachute substation, approximately five miles away. The annual production is expected to be 1,951 kWh/kW per year, or 31,851 MWh, which is enough power to meet about 2.5% of HCE’s load, or approximately 4,392 homes' annual electricity use. If approved for this permit, AES will work to begin construction as soon as June 21st, 2021, after Board of County Commisioners' approval with a target completion and commercial operation date no later than December 31st, 2022. Thank you for your consideration of our permit application. If approved, we look forward to working with Garfield County, HCE, and its residents and customers in a long-term partnership delivering clean energy to the Western Slope.

Klebold to AES High Mesa Solar, LLC granting it to be an Authorized Representative with regards to this Land Use Change – Major Impact permit application. LETTER OF AUTHORIZATION Section A8 AES High Mesa Solar – Land Use Change – Major Impact permit application (10/22/2021) AES High Mesa Solar – Garfield County 18 Site Summary The High Mesa Project is located on the property of Larry A. and Karen K. Klebold in Parachute, Garfield County, Colorado (parcel #240935100136). The property is approximately 340.01 acres and consists of two primary areas situated on a flat top plateau. The northern area is used for crop growth and residence, in addition to hosting two oil/gas pad infrastructure areas. The southern area is vacant and wooded. Away from the project area to the east, a ravine features prominently as a steep, vacant, and wooded area that contains underground natural gas lines. Operational Details and Technical Description AES designed the High Mesa Solar facility to utilize its unique “PV Peaker” architecture which tightly couples solar and storage to maximize operating efficiency, reduce capital and operating expenses, and more effectively shape the production of locally sourced renewable energy. This reduces demand from conventional resources resulting in a smoother demand profile during the Holy Cross’s desired dispatch timeframe. AES’s “PV Peaker” solar + battery energy storage system (BESS) system will include multiple “Power Blocks” distributed throughout the site. Each block includes PV modules on single-axis trackers, inverters, transformers and containerized lithium-ion batteries to store and then reliably dispatch the solar whenever it is requested. A rendering of a typical Power Block is shown below: NARRATIVE DESCRIPTION OF PROPOSED USE INCLUDING OPERATIONAL DETAILS, TECHNOLOGY DESCRIPTION, AND OTHER REQUIRED PERMITS Section A9 AES High Mesa Solar – Land Use Change – Major Impact permit application (10/22/2021) AES High Mesa Solar – Garfield County 19 The DC-coupled storage-integrated solar power plant design means the PV will be connected on the same DC bus as the BESS through the installation of DC/DC conversion units, which will then feed into a shared bi-directional inverter. Energy could be drawn from the PV or the grid to charge the batteries during normal operations. The AES system provides the following functional output options: • PV energy directly to the grid through the inverter • PV energy directly to the BESS for storage without passing through an inverter • PV energy partially to the grid and partially to the BESS for storage • Combination of PV + energy stored in BESS direct to the grid through the inverter • Energy from BESS to the grid, without PV support. • Energy to BESS from the grid The DC-coupled architecture saves on redundant equipment such as inverters and transformers while increasing overall solar integration with BESS roundtrip efficiency compared with an AC-coupled system. A simplified block diagram of the DC coupled architecture is shown below to help illustrate its functionality: AES and its partners have co-developed a suite of technologies optimized to this “PV Peaker”. The power conversion systems (PCS) regulate output and efficiently balance energy storage with PV generation. Battery enclosures include proper climate control, monitoring systems, and fire-suppression to extend energy storage life and maintain safe operations. The power plant controller (PPC) determines proper dispatch according to forecasted weather and demand profiles. AES High Mesa Solar – Land Use Change – Major Impact permit application (10/22/2021) AES High Mesa Solar – Garfield County 20 AES has established a 15-minute step performance model to analyze and optimize the sizing of PV+BESS systems. The PV generation is based on satellite modeling for solar irradiance and uses PVSyst to calculate the DC output of the solar plant. The model processes raw data from PVSyst along with parameters describing the BESS, and balance-of-system (BOS), as well as utility requirements. The AES PV Peaker design employs high-energy-density lithium-ion batteries and high-power PV modules linked together on a fixed-voltage common DC bus at each inverter power block. The inverters are connected to step-up transformers to convert the inverter output to a medium-voltage plant distribution loop, which then utilizes a switchgear and riser poles to connect to the 24.9 kV three phase distribution feeder belonging to Holy Cross at the point of interconnection. Dispatch Characteristics DC-coupled Solar PV + BESS offers superior dispatch flexibility and simplicity compared to the intermittent generation of standalone solar PV. The Power Plant Controller (PPC) will respond to the dispatch signal set at the POI by using a closed-loop control scheme to inject the requested power with the solar PV and/or BESS. Solar PV power is used first to meet the power requirement, supplementing and/or exclusively using BESS power when not enough PV power is available. Equipment Specifications This project will utilize BYD MLTK-36-525W bifacial photovoltaic modules mounted on Soltec SF7 single axis trackers for power generation. These modules will be paired with AMPT V1400-32-24 string optimizers and GPTech AMPS2Ms2.2BsWD3-V850 central inverters. The GPTech inverter is also equipped with a DC/DC converter which will be used to charge and discharge the Samsung E4D battery modules. Please see our site plans in Section B2 and Section A9 for technical description and operational details. AES can provide equipment specification documents upon request, as they are quite lengthy. AES High Mesa Solar – Land Use Change – Major Impact permit application (10/22/2021) AES High Mesa Solar – Garfield County 21 Permitting Summary The anticipated list of permits and consultations that support the development of this project is as follows: • Garfield County: o Land Use Change Permit (Major Impact Review) is needed. o Separate fencing installation permit may be needed. o County access permit or waiver request needed for use of Stone Quarry Road by overweight vehicles, if necessary. o Stormwater Permit needed and an application was submitted to CDPHE on (11/8/21) o Grading/Driveway Construction Permit • State of Colorado: Electrical Construction Permit • Army Corps of Engineers (Wetlands/Waters of the U.S): Finding of No Impact / No Jurisdiction. No permits needed. A wetlands delineation was performed of the subject property in November 2020 by a Professional Wetlands Scientist in Colorado. The delineation identified three unconsolidated bottom wetlands, two irrigation ditches with ephemeral flow, one ephemeral stream, one irrigation ditch with intermittent flow, and one intermittent stream. Impacts to these features will be avoided as confirmed by informal consultation with US Army Corps of Engineers (USACE). Additionally, no floodplain encroachment will occur from the proposed project. See the narrative to 7-203: Protection of Waterbodies later in this application and Appendix C1 for completed wetland delineation reports and further detail. • US Fish & Wildlife / Colorado Parks & Wildlife: Wildlife Impact Mitigation strategy; consultation ongoing. No permits needed. AES and its consultants HDR have been in close contact with USFWS and CPW regarding considerations and guidance around identified listed species at both Federal and State level. A comprehensive biological survey per CPW and USFWS guidelines was conducted of the site in November 2020. See the narrative to 7-202: Wildlife Habitat Areas later in this application and Appendix C2 for the Biological Resource report and Colorado Hookless Cactus survey for further details. AES High Mesa Solar – Land Use Change – Major Impact permit application (10/22/2021) AES High Mesa Solar – Garfield County 22 • Colorado Department of Transportation: No access permits needed for use of the I-70 ramps or Old US Highway 6. • Hazardous Materials: No Action needed. A Phase I Environmental Site Assessment (ESA) was conducted in accordance with the scope and limitations of American Society for Testing and Materials (ASTM) Practice E1527-13 in January 2021. Two RECs, one HREC, zero CRECs, and one BER have been identified on the greater property beyond the anticipated project footprint. The RECs, HREC and BER are associated with the oil/gas infrastructure pads located on or adjacent to the High Mesa Compressor Station. The proposed project will not impact this area of the property and no further action is needed. As pertains directly to the proposed Project, there are no hazardous materials to be transported or released on site during the construction, operation, or decommissioning of the Project, and there are no toxic or flammable gasses released during charging, discharging, or normal operation of the facility. Lubricating oil in the transformers will have effective containment measures and while neither photovoltaic panels or lithium-ion batteries are considered as hazardous materials in their use state, especially given the commonality of solar panels on residential rooftops and cell phones in pockets, the presence of various metals in their componentry compels the need for responsible post-life recycling, which AES will commit to pursuing. See appendix C3 for the Phase I Environmental Site Assessment report. • Cultural Resources: No Action needed. A Class I cultural resources review was completed by a Colorado-based Registered Professional Archaeologist (RPA) in December 2020. No known historical properties will be impacted by the proposed project. If any ground disturbance during the course of the proposed project exposes artifacts, foundation, or other indications of past human occupation, AES will notify the State Historic Preservation Officer and OAHP. See appendix C4 for the Cultural Resources review report. • FAA: No Action needed. The FAA issued a Determination of No Hazard to Air Navigation for the proposed project on 02/11/2021. See Appendix C5 for documentation. AES High Mesa Solar – Land Use Change – Major Impact permit application (10/22/2021) AES High Mesa Solar – Garfield County 23 • Air Quality: No Action needed.

COPY OF PRE-APPLICATION SUMMARY Section A10 1 Community Development Department 108 8th Street, Suite 401 Glenwood Springs, CO 81601 (970) 945-8212 www.garfield-county.com PRE-APPLICATION CONFERENCE SUMMARY TAX PARCEL NUMBER: 2409-351-00-136 DATE: November 17, 2020 PROJECT: Solar Energy System, Large OWNER: Larry and Karen Klebold REPRESENTATIVE: AES Solar – Joshua Mayer PRACTICAL LOCATION: 1691 County Road 300, Parachute, CO 81635 ZONING: Rural TYPE OF APPLICATION: Major Impact Review – Land Use Change Permit I. GENERAL PROJECT DESCRIPTION The Applicant is proposing to develop a solar facility on the subject property. The facility is proposed to be 10 megawatts and will include lithium batteries for storage. Battery storage is anticipated to be approximately the size of an industrial shipping container. HVAC will be installed to cool the unit. The power from the solar facility will tie into Holy Cross Energy’s facilities. As the three-phase infrastructure for connection is located on an adjacent property, the applicant will need to provide demonstration of an easement for utilities connections. The subject property is located south of Parachute. The applicant is proposing to purchase the subject property for the operation of the facility. If the applicant is not the property owner at the time of application submittal, the applicant will need to provide authorization from the property owner. The applicant has also expressed the possibility of subdividing the property in to two separate parcels, for which a separate minor subdivision process would be required if the parcels are to be less than 35 acres. The subject property has existing developments, including some buildings on the western portion of the property, and oil and gas developments throughout the property. The parcel appears to sit atop a mesa, with steep slopes on all sides of the parcel, however, the upper portion of the property where the facility is proposed to be located appears to be relatively flat. Topography information will need to be included on site plans, as well as other relevant site features including but not limited to any ditches on the property. 2 The applicant will need to demonstrate water usage and wastewater disposal at the site both during and after construction. The applicant has indicated that no water or wastewater will be required to serve the solar facility in the long term. The applicant will need to address why permanent water and wastewater infrastructure will not be anticipated on site within the water and wastewater plans. The applicant has represented that the project will be built in one phase and that a Development Agreement will not be required. Waivers should be requested from submittal of development agreements and improvement agreements. All waiver requests for submittal requirements need to address the waiver criteria outlined in Section 4-202.C of the Land Use and Development Code (LUDC). The applicant will need to provide information on soils and other significant geological features. A grading and drainage plan will also need to be provided demonstrating compliance with Section 4-203.E of the LUDC. Such reports will need to be prepared by a qualified professional. The applicant may request to provide this information as a condition of approval. The applicant will be required to conform to setback requirements for the Rural Zone District. Requirements on lot coverage specific to solar facilities are not specified in the LUDC. While natural landscape features may provide some limitations on lot coverage, the lot coverage will be determined by the BOCC. Construction will be for a short period of time with minimal traffic generation for routine maintenance after the initial constriction period. The site is accessed off County Road 304/Richardson Road. The applicant will need to provide access easements as necessary. Additionally, the applicant will need to analyze the access road for compliance with Section 7- 107 roadway dimensional standards as described in the Land Use and Develop ment Code. Because dimensional standards for roads are determined based on traffic generation, and construction traffic will likely be greater than the long-term traffic for the facility, a waiver may be appropriate for the design standards required for the access road. A waiver may be requested on roadway standards according to Policy 01-14 Waivers for Roads and Demonstration of Compliance (attached). Staff recommends that the applicant coordinate with the appropriate fire district and Colorado Parks and Wildlife for any early referral comments. The application will be referred to these entities, and early coordination may assist in identifying and addressing potential concerns. II.
