San Marcos Office Building Solar: Local Market Context
Why San Marcos
San Marcos office buildings serve a workforce anchored by Texas State University, the city's largest employer with over 38,000 students and 5,000 staff, creating consistent Monday-Friday daytime occupancy patterns. With 5.1 peak sun hours daily and NREL-rated production of 1,535 kWh per installed kW annually, rooftop systems generate maximum output precisely when university-adjacent professional offices run HVAC systems hardest during Central Texas summers.
Industrial Corridors
Office properties concentrate along the I-35 corridor near Centerpoint Station and in the Hays County Government Complex area, where commercial development has intensified to serve San Marcos's 70,000 residents and the university ecosystem. Additional office inventory clusters around the Post Road and Hunter Road commercial districts, where Pedernales Electric maintains distribution infrastructure originally built for lower-density loads now supporting professional service tenants.
Pedernales Electric Specifics
Pedernales Electric, a member-owned cooperative serving the San Marcos area, applies an $8/kW demand charge to commercial accounts that solar can mitigate during summer peak windows when office HVAC drives monthly demand peaks. Because Texas operates a deregulated electricity market but Pedernales remains a municipal cooperative outside ERCOT's retail choice zones, San Marcos office owners face the cooperative's fixed $0.103/kWh rate structure without the ability to shop for alternative supply, making on-site solar generation the primary tool for rate arbitrage.
