Irvington Campus Modernization
Efficient natural gas generators at our largest local power plant will support the expansion of TEP's wind and solar energy resources.
RICE Generators
New, efficient generators will replace two older natural gas-fired units at the H. Wilson Sundt Generating Station in Tucson, improving the plant’s performance while reducing operating costs, water usage and emissions.
Reciprocating Internal Combustion Engine (RICE) Generation and Irvington 138-Kilovolt Transmission Line Relocation
In March 2018, the ACC approved a Certificate of Environmental Compatibility (CEC) for TEP’s Reciprocating Internal Combustion Engine (RICE) Generation and Irvington 138-Kilovolt Transmission Line Relocation project.
Sundt Generating Station Air Quality Permit Update
The Pima County Department of Environmental Quality approved modification of an existing air quality permit for TEP in August 2018, allowing for the construction of the new RICE units and continued operations at the H. Wilson Sundt Generating Station.
Irvington Campus Planned Area Development
In April 2018, the Tucson City Council approved Planned Area Development (PAD) zoning for TEP’s Irvington Campus, site of new and upgraded generation and transmission resources. The zoning supports comprehensively-planned development and allows the company to move forward with improvements that accommodate our community’s changing energy needs.
