At the end of 2022, TNMP built a new station for the solar company to interconnect. It will be the first solar farm that TNMP has interconnected at transmission voltage.

TNMP typically considers transmission voltage to include three phase lines operated at 60,000 Volts (60 kV) line-to-line or above. TNMP owns transmission lines that operate at nominal line-to-line voltages of 69 kV, 138 kV, and 345 kV throughout Texas.

“We are excited to add our first transmission interconnected solar generation plant to the TNMP system.  Solar is a growing renewable resource supporting the Texas electric system, and we look forward to adding more solar plants in the future,” said Nicole Hitchcock, Team Manager for Project Management.

TNMP has other smaller solar generation plants connected to the TNMP system at lower distribution voltages. This is the first solar generation plant connected to TNMP’s system at the higher (greater than 60 kV) transmission voltage level.

​​​​​The Dileo Solar Farm is a 500-acre site located in Central Texas. This solar facility utilizes 162,000 individual solar panels and can generate 72 megawatts of energy.

The project has been in construction since early 2020 and was energized at the end of June. Another solar farm is planned for 2025 in Central Texas.

TNMP is a transmission and distribution service provider that delivers power to more than 260,000 homes and businesses on behalf of retail electric providers in Texas. More information is available at
