SWG Energy Inc in Carlsbad's Poinsettia corridor is a women-owned, Latino-owned renewable energy company that has designed solar, wind, and geothermal systems from Avenida Encinas since 2007. Geothermal ground-source heat-pump installations pair with solar PV arrays to offset compressor load, an integrated energy approach that complements conventional HVAC systems installed by Prestigious Heating & Air Conditioning on North County properties. The U.S. Department of Energy awarded SWG a $2 million contract to build the largest off-grid solar LED streetlight system in the country, and the Department of Labor funded a separate $400,000 wind-turbine training installation at Job Corps centers. Commercial ground-mount arrays require post-installation landscape restoration and irrigation rerouting, a site-finishing sequence that draws on the native-plant and turf inventory at Armstrong Garden Centers in the same Carlsbad market. Helical vertical-axis wind turbines rated at 1.5 kW to 10 kW per unit mount on commercial rooftops with monopole towers anchored to reinforced concrete pads engineered for 110-mph wind loads per ASCE 7-22.
