Technical Specifications

The Edward W. Clark Generating Station comprises a diverse mix of thermal and renewable generation assets totaling 1,102 megawatts of installed capacity. The facility is situated on a 115-acre (47 ha) site in Whitney, Nevada, and is owned and operated by Nevada Power. The plant’s configuration reflects decades of incremental expansion, beginning with its initial commissioning in 1954 as the utility’s first gas-fired power plant. The current infrastructure includes steam turbines, gas turbines, and a small photovoltaic array, reflecting a transition from older thermal units to more modern combined-cycle and simple-cycle technologies.

Thermal Generation Units

The core of the station consists of 19 thermal units. The earliest major addition to the original infrastructure was a General Electric MS-7000 unit, which entered service in 1973. This unit represents the steam turbine technology that characterized mid-20th-century gas-fired generation. In later expansions, the plant incorporated two Mitsubishi steam recycled heat gas-fired turbines. These units utilize waste heat recovery systems to improve thermal efficiency, a common feature in modern gas-fired combined-cycle plants. The most significant recent addition to the thermal fleet is a set of 12 Pratt & Whitney FT8 units, commissioned in 2008. These simple-cycle gas turbines provide flexible peaking capacity, allowing Nevada Power to respond quickly to fluctuations in electricity demand in the Las Vegas Valley. The specific capacity contributions of each unit type are detailed in the table below, which aggregates the total installed capacity of the thermal fleet.

Steam Turbine	General Electric	1973	[?]
Steam Recycled Heat Gas-Fired Turbine	Mitsubishi	[?]	[?]
Simple-Cycle Gas Turbine	Pratt & Whitney	2008	[?]

Renewable Energy Integration

In addition to its thermal generation capabilities, the Edward W. Clark Generating Station includes a 75-kilowatt photovoltaic (PV) system. This small-scale solar installation demonstrates the plant’s integration of renewable energy sources into its overall generation mix. While the PV system contributes a modest amount of electricity compared to the thermal units, it provides a degree of operational flexibility and reduces the plant’s carbon footprint during peak sunlight hours. The PV system is part of a broader trend among utility-scale power plants to incorporate on-site renewable generation to enhance efficiency and meet regulatory or corporate sustainability goals. The total capacity of the PV system is 75 kW, which is negligible in comparison to the 1,102 MW total capacity of the thermal fleet but represents an important step in the plant’s modernization efforts.

What is the role of solar integration at Edward W. Clark?

The Edward W. Clark Generating Station is primarily defined by its natural gas-fired infrastructure, yet it incorporates a specialized photovoltaic system that serves as a technical benchmark for utility-scale solar integration. This 75-kilowatt photovoltaic array represents a strategic deviation from the plant’s core thermal generation model, functioning as a collaborative research initiative rather than a primary power source. The system was jointly developed through a partnership involving Nevada Power, the University of Nevada, and the National Renewable Energy Laboratory, leveraging the academic and federal expertise to optimize solar performance in the high-irradiance environment of the Las Vegas Valley.

Research Collaboration and Technical Significance

The development of this photovoltaic system highlights a multi-institutional approach to energy infrastructure innovation. By partnering with the University of Nevada and the National Renewable Energy Laboratory, Nevada Power established a living laboratory on the 115-acre site in Whitney, Nevada. This collaboration allowed for the rigorous testing of solar technologies under real-world operating conditions, directly adjacent to the plant’s 19 gas-fired units. The 75-kilowatt capacity, while modest compared to the plant’s total output, provided critical data on efficiency, maintenance requirements, and grid interaction specific to the local microclimate.

Context Within Gas-Fired Dominance

Despite the presence of this solar installation, the Edward W. Clark Generating Station remains overwhelmingly dependent on natural gas. The plant’s primary capacity, which reached 1,375.6 megawatts in later expansions, dwarfs the 75-kilowatt solar contribution, underscoring that the photovoltaic system serves more as a pilot project and educational tool than a major generation asset. Commissioned in 1954 as Nevada Power’s first gas power plant, the facility’s identity is rooted in thermal generation. The solar integration does not displace a significant portion of the gas-fired output but rather complements the plant’s operational profile by demonstrating the viability of hybrid renewable technologies within an established utility footprint. This approach allows Nevada Power to maintain grid reliability through its robust gas units while simultaneously advancing solar research through targeted, low-risk deployments. The significance of this integration lies in its ability to bridge traditional thermal generation with emerging solar technologies, providing a model for how established power plants can incorporate renewable energy research without compromising their primary operational efficiency.
