POWER PURCHASE AGREEMENT ("PPA") Exhibit 8 Project Requirements 7. Project Requirements 7.1. Electrical Service and Interconnection Requirements 7.1.1.The CONTRACTOR shall provide a layout of the solar system and identify the location of the interconnection to the utility and the host COD metered account. 7.1.2.The CONTRACTOR shall interconnect the solar system with the existing building service and this service shall be independent of the other services required by the facility. 7.1.3.The contractor is to determine the main service amperage for each account to be associated with the solar system. 7.1.4 The solar system shall be a Net Meter interconnection with Ameren Illinois in accordance with the current Distributed Generation Interconnection Administration Code. 7.1.5.The existing meter shall be replaced by Ameren, Illinois to provide a two-way meter capable of measuring the flow of electricity in two directions. 7.1.6. Due to the location of the service interconnections, a separate solar system disconnect panel shall be located near the main entrance for use by fire and emergency services with access to be approved by Authority Having Jurisdiction (AHJ). 7.2. Design Requirements 7.2.1.The CONTRACTOR shall commence the design of the solar system with the preparation of"design development"contract documents to include but not be limited to outline specifications,detailed implementation/construction plans, and detailed permit/regulatory submission plans to be submitted for COD review and comment. 7.2.2.The CONTRACTOR shall include 35%design drawings on the solar grid support structure,solar array layout, electrical equipment, and electrical interconnection/metering. 7.2.3.The CONTRACTOR shall include specifications for the solar panels, inverters, electrical equipment, electrical interconnection/metering,system controls and monitoring equipment. 7.2.4.The CONTRACTOR shall include specifications for the solar grid support with design drawings, design calculations, and design load calculation based on the existing building structure capacity to support the new load for the solar system. 7.2.5.The CONTRACTOR shall provide relevant technical documentation of the technologies proposed to be installed for the solar system. 7.2.6.The CONTRACTOR shall provide a PVSYST model run for the system size being proposed which supports the data included in the Proposal to include but not limited to: • Maximum Guaranteed power capacity(DC kW), measured at the inverter(s) input. • Guaranteed power capacity(AC kW), measured at the inverter(s)output.
