    Yosemite National Park, California

    The El Portal Administrative Complex represents the administrative center of Yosemite National Park, and the complex houses Yosemite’s primary maintenance facility, its largest wastewater treatment plant, and administrative offices. The new photovoltaic system at El Portal is the largest NPS-managed photovoltaic (PV) project within the NPS Pacific West Region and the largest grid-connected PV system owned and operated by the NPS. The 672 kW system consists of 2,800 solar panels and produces approximately 800,000 kWh per year. This level of production will provide approximately 30% of El Portal’s annual electricity; the complex itself is responsible for using approximately 40% of the park’s entire power load. El Portal serves was chosen as the location for the PV installation based on the high levels of direct sunlight the site receives. The PV panels were installed on the roofs/walls of existing buildings and on newly constructed structures to provide shading for government vehicles parked at the site, where summer temperatures regularly exceed 100°F, even in the shade. Installation of this PV system will provide a number of benefits to the environment and grid operations when compared to using non-renewable energy sources such as oil, coal, or natural gas. Since the PV system cleanly harnesses energy from a renewable resource (the sun), harmful emissions into the atmosphere will be curtailed. For example, the system is anticipated to reduce carbon dioxide emissions by 300 tons each year compared to an equivalent amount of power generated by conventional methods. The system will lessen demands on California’s frequently overloaded power grid and will help reduce the need for rolling blackouts throughout the state. The RMH Group provided conceptual design including development of overall design parameters and determination of logistics for sizing and placement of the PV equipment. RMH also closely coordinated with the local uility company for connection of the PV system to the utility grid.
