Dallas Office Building Solar: Local Market Context
Why Dallas
Dallas's massive finance and telecom sectors—anchored by employers like Charles Schwab, AT&T, and Fidelity—drive weekday daytime office occupancy that peaks between 10 a.m. and 4 p.m., precisely matching the city's 5.0 peak sun hours per day. With 1,510 kWh/kW/year of solar production potential, a 500 kW rooftop system on a typical Dallas office building offsets roughly 755,000 kWh annually, directly reducing both the $0.102/kWh energy charge and the $8.5/kW demand charge during those air-conditioning-heavy summer afternoons when Texas grid prices spike.
Industrial Corridors
Office buildings clustered in Uptown, the Las Colinas Urban Center, and the North Dallas Tollway corridor—home to corporate campuses for Liberty Mutual, Toyota North America, and ExxonMobil's campus—represent over 150 million square feet of Class A and B office space with ideal flat-roof profiles for solar arrays. The Legacy West development and Frisco's $5 billion mile adds millions more square feet of new construction where solar-ready designs are increasingly standard, particularly for LEED-targeted projects seeking to lock in electricity costs in Texas's deregulated market.
Oncor Specifics
Oncor, as the transmission and distribution utility, requires commercial solar installations to submit an Interconnection Request under its Distributed Generation Interconnection Manual, with systems over 100 kW subject to detailed engineering review and potential system impact studies if aggregate capacity in a given network segment approaches transformer limits. Because Dallas operates in ERCOT's deregulated market, office owners retain their retail electricity provider (REP) while Oncor handles metering and net metering credits under Texas's Senate Bill 1125 framework, meaning exported solar generation is credited at the REP's negotiated avoided-cost rate rather than the retail $0.102/kWh—making on-site consumption optimization critical for maximizing ROI.
