Austin Energy on Dec. 2 filed with the Public Utility Commission of Texas an interconnect agreement for the 30-MW Mustang Solar Power Plant project of Mustang Solar I LLC.

Under this agreement, Austin Energy will construct a three position 138 kV ring bus switchyard cut into Austin Energy circuit 988 (Lytton Springs-Slaughter Lane) and tied to the Mustang Solar Plant. The point of interconnection is located between the new Austin Energy Mustang Solar Switchyard and the adjacent Mustang Solar Plant both located about seven miles northwest of the existing Lytton Springs Substation in Travis County, Texas.

The power project will have 30 inverter units (each unit is rated at 1 MW (ac)), for a total facility capacity of 30 MW (ac). The solar plant would have 35 MW (dc) of photovoltaic panels connected to the DC to AC inverters.
