Alternative Energy Systems Consulting in Carlsbad has delivered energy engineering and consulting services to California's major investor-owned utilities since the firm's founding in 1994, operating from its Impala Drive headquarters with a team of over 70 engineers and energy specialists. Building-electrification audits identify photovoltaic and battery-storage integration points, a scope that coordinates with solar installation firms including San Diego County Solar for panel-layout optimization and interconnection-agreement support. The firm's proprietary PRAXIS cloud-based software platform manages energy project pipelines from initial audit through measurement and verification, serving utility rebate programs for PG&E, Southern California Edison, and SDG&E. Energy-efficiency retrofit specifications for commercial buildings pair with renovation contractors such as Mastercraft Home Improvement for envelope-sealing, insulation-upgrade, and HVAC-replacement scopes. Highest-complexity engagements include California Self-Generation Incentive Program technical reviews, Title 24 compliance modeling, and grid-integration studies for intermittent renewable resources paired with battery-storage dispatch optimization.
