Energy Usage Analysis
Energy Usage Analysis – Phoenix, AZ
Energy usage analysis examines your Phoenix facility’s electrical consumption patterns to identify where and when energy is used, reveal opportunities for cost reduction, support sustainability initiatives, and provide baseline data for energy management programs. Phoenix Contracting Services provides comprehensive energy usage analysis for commercial, industrial, and residential properties throughout the Phoenix metro area, combining monitored electrical data with operational analysis to deliver actionable insights that reduce utility costs, improve efficiency, and support environmental goals while maintaining or improving facility operations.
Energy analysis goes beyond simple utility bill review by monitoring actual electrical consumption over time, breaking down energy use by time period, load type, and operational mode to identify specific opportunities for improvement. We analyze energy consumption patterns across hours, days, weeks, and months to reveal peak usage times, identify base loads consuming power 24/7, quantify energy waste from inefficient equipment or operations, and compare your facility’s energy intensity to industry benchmarks and best practices for similar Phoenix facilities.

What Our Energy Analysis Reveals
Time-Based Energy Consumption Patterns
We analyze energy usage across different time periods including hour-by-hour consumption profiles showing when facility uses most energy, weekday vs. weekend usage patterns revealing operational differences, seasonal variations affecting HVAC and process loads, and shift-to-shift consumption comparing energy use across different operating schedules. Time-based analysis identifies opportunities for load shifting to off-peak periods, reveals unnecessary after-hours energy consumption, and supports time-of-use rate optimization strategies.
Peak Demand Analysis & Cost Impact
For facilities with demand charges, we analyze peak demand events, including identification of monthly peak demand periods that drive charges, analysis of what equipment or operations create peak demand, calculation of demand charge costs as a percentage of total utility expense, and evaluation of demand reduction strategies, including load shedding, demand response participation, and equipment scheduling optimization. Peak demand reduction often provides the fastest payback of any energy project.
Base Load & Always-On Energy Consumption
Analysis identifies base load, the minimum power your facility draws 24/7, including HVAC systems running continuously, always-on IT equipment and servers, lighting left on after hours, phantom loads from equipment in standby mode, and process equipment that runs regardless of production schedule. Base load typically represents 30-50% of total energy consumption and offers significant reduction opportunities through equipment scheduling, control system improvements, and elimination of unnecessary always-on loads.
Equipment-Specific Energy Consumption
When monitoring includes equipment-level data, we analyze energy consumption by major equipment category, including HVAC energy consumption and efficiency trends, lighting system energy use and opportunities for LED upgrades, motor and compressed air system efficiency, process equipment energy intensity and duty cycles, and plug load consumption from office equipment and miscellaneous loads. Equipment-specific data prioritizes capital improvement investments for best energy savings return.
Energy Cost Breakdown & Rate Analysis
We analyze utility rate structures and cost drivers, including energy charges (kWh consumption costs), demand charges (peak kW demand costs), time-of-use rate impacts showing cost differences between peak and off-peak periods, power factor penalties if applicable, and comparison of actual costs to optimized consumption patterns. Rate analysis often reveals that shifting just 10-15% of load from peak to off-peak periods can reduce utility costs 15-25%.

Energy Savings Opportunities & ROI Estimates
Our analysis identifies and prioritizes energy saving opportunities, including estimated energy reduction (kWh and percentage), annual cost savings at current utility rates, capital investment required for implementation, simple payback period, and return on investment, and non-energy benefits like improved comfort, reliability, or equipment life. Prioritized recommendations enable data-driven decision-making about which projects to pursue first.
How Energy Analysis Saves Money
Energy usage analysis typically identifies savings opportunities totaling 15-30% of current energy costs through a combination of operational changes (no cost), controls improvements (low cost), and equipment upgrades (higher cost with faster payback). A Phoenix warehouse facility spending $85,000 annually on electricity requested an energy analysis to identify savings. Our monitoring revealed that HVAC systems ran at full capacity 24/7, including nights and weekends when the facility was unoccupied, lighting remained on after hours in areas without motion sensors, the compressed air system ran continuously despite production only occurring during the day shift, and power factor averaged 0.75, resulting in utility penalties.
We recommended programmable thermostats for after-hours setback ($3,000), lighting controls and LED upgrades ($18,000), compressed air system controls and leak repair ($8,000), and power factor correction capacitors ($12,000). Total investment of $41,000 reduced annual energy costs by $28,000 (33% reduction), providing a 1.5-year payback. The facility also qualified for $8,500 in utility rebates, reducing net investment to $32,500 and improving payback to 14 months.
When energy analysis identifies infrastructure limitations, our commercial electrical services address issues including panel upgrades to support energy efficiency equipment and power factor correction installations to eliminate utility penalties.

Frequently Asked Questions
Frequently Asked Questions
How is energy analysis different from just reviewing utility bills?
Utility bills show total consumption and cost but don’t reveal when energy is used, what equipment consumes energy, or where opportunities exist for reduction. Energy usage analysis monitors actual consumption patterns over time, breaks down energy by time period and load type, identifies specific equipment and operational patterns driving costs, and provides detailed recommendations for reduction. Bills show results; analysis shows causes and solutions.
What data do you need to perform energy analysis?
We need monitored electrical consumption data collected over at least 2-4 weeks (preferably 30+ days), utility bills for the past 12 months showing rate structure and costs, facility operational schedule and production patterns, major equipment inventory with approximate operating hours, and recent utility rate tariff. We collect most electrical data through our monitoring equipment installation, and work with facility managers to understand operational patterns affecting energy use.
Can energy analysis help with sustainability reporting?
Yes, energy analysis provides comprehensive baseline data required for most sustainability programs, including total annual energy consumption (kWh), energy intensity (kWh per square foot or per unit produced), breakdown by energy end-use category, and tracking data showing progress toward reduction goals. Our analysis supports LEED certification, Energy Star applications, carbon footprint calculations, and corporate sustainability reporting requirements.
How much does energy usage analysis cost?
Energy analysis is typically included as part of comprehensive load study services (ranging $2,500-$7,500) or can be performed as a standalone service ($1,500-$4,000), depending on facility complexity and depth of analysis required. Investment typically pays for itself many times over through identified savings opportunities, and many Arizona utilities offer rebates or incentives that offset analysis costs.
