Plano Office Building Solar: Local Market Context
Why Plano
Plano's concentration of Fortune 500 headquarters and tech campuses—including Toyota North America, JPMorgan Chase, and Liberty Mutual—creates a commercial office market where demand charges at $8.50/kW represent 25-35% of monthly electric bills during summer cooling peaks. With office HVAC loads spiking between 11 a.m. and 4 p.m. when Plano's 5.0 peak sun hours deliver maximum output, solar directly offsets both kilowatt-hour charges at $0.102 and costly demand ratchets that persist through North Texas' 100°F July and August afternoons.
Industrial Corridors
Office buildings dominate Legacy West, the Central Expressway (US-75) corridor between Spring Creek Parkway and Parker Road, and the established Corporate Center district near Granite Parkway where multi-tenant Class A properties routinely carry 300-600 kW peak demands. The Shops at Legacy and adjacent corporate campuses along the Dallas North Tollway have become Plano's densest office submarket, with flat rooftops ideal for commercial arrays generating 1,510 kWh per installed kW annually.
Oncor Specifics
Oncor processes distributed generation interconnection applications under the Texas Public Utility Commission's TAC §25.211 framework, typically requiring net metering agreements for systems above 25 kW that export to the grid during low-occupancy periods like weekends. Because Plano operates in ERCOT's deregulated market, office owners select retail electric providers separately from Oncor's transmission/distribution service, meaning solar economics must account for both Oncor's demand charge pass-throughs and the specific energy rate negotiated with providers like TXU Energy or Direct Energy on commercial contracts.
