Energy Trends in Rialto
Several trends are reshaping energy supply. Time-of-use electricity rates encourage customers to shift usage away from late afternoon and evening peaks. Battery storage is growing quickly, both in homes and at commercial facilities. Electrification of buildings and vehicles is increasing electricity demand, especially at warehouses installing charging infrastructure for electric trucks.
Grid reliability is also a focus, particularly during heat waves. Demand response programs reward customers for reducing consumption during peak events, helping stabilize the grid and lower costs.
Tips for Lowering Energy Costs
Start by reviewing your utility rate plan to ensure it matches your usage patterns. Consider an energy audit to identify efficiency opportunities such as LED lighting, improved insulation, and high-efficiency HVAC systems. Businesses should explore commercial solar, battery storage, and demand response programs. Eligible households can enroll in discount programs offered by SCE and SoCalGas.
For larger commercial customers, comparing Direct Access offers, where available, may provide pricing advantages or renewable energy options.
Energy Considerations for Rialto Warehouses
Warehouses and distribution centers are among the largest energy users in Rialto. Lighting, refrigeration, conveyor systems, automated sorting equipment, and battery chargers for forklifts all draw significant power. As fleets transition to electric trucks, facilities may need major electrical service upgrades and coordination with the utility well before chargers are installed.
Facility managers can lower costs by installing LED high-bay lighting with motion sensors, upgrading HVAC and refrigeration controls, and scheduling heavy equipment charging during off-peak hours. On-site solar and battery storage can reduce demand charges and provide backup power to keep critical operations running during outages. Working with an experienced energy services partner helps businesses plan these investments strategically and capture available incentives.
Early coordination is especially important for large charging projects, since utility upgrades can take many months to design and complete.
