Energy Efficiency & Demand Response KPIs by Sector

Essential KPIs for energy efficiency programs and demand response participation, with 2024-2025 benchmark ranges across sectors and guidance on verified savings measurement.

Energy efficiency remains the cheapest, fastest, and most scalable climate solution. The IEA estimates that efficiency improvements could deliver 40% of emissions reductions needed for net zero. Demand response—shifting or reducing electricity consumption in response to grid signals—adds value by enabling higher renewable penetration and avoiding grid infrastructure investments. This benchmark deck provides the KPIs that matter for both efficiency and flexibility, with ranges drawn from 2024-2025 programs across sectors.

The Twin Opportunities

Energy efficiency saves money while reducing emissions. McKinsey's 2024 analysis found that efficiency investments average 20-30% returns through reduced energy costs—outperforming most capital investments. Yet the "efficiency gap" persists: economically rational investments go unmade due to split incentives, information gaps, and capital constraints.

Demand response creates additional value by providing grid services. PJM (US regional grid) paid $2 billion to demand response resources in 2024. California's CAISO relies on demand response for 4-6% of peak capacity. As grids integrate more variable renewables, flexibility value is increasing.

The convergence matters: efficient buildings with smart controls can both reduce total consumption and shift remaining consumption to optimal times. This combined approach maximizes economic and environmental value.

The 8 KPIs That Matter

1. Energy Use Intensity (EUI)

Definition: Energy consumption normalized by floor area (kWh/m² or kBtu/sqft annually).

Building TypeBottom QuartileMedianTop QuartileBest Practice
Office (Standard)>250 kWh/m²180-220120-160<80
Office (Data-Intensive)>350250-320180-240<140
Retail (Grocery)>500380-450280-360<220
Retail (Other)>300200-270140-190<100
Healthcare (Hospital)>400300-380220-290<180
Education (School)>180130-17090-125<70
Industrial (Mfg)>400280-380180-260<150
Data CenterPUE-based--See PUE

Normalization essential: Raw EUI comparisons across buildings are misleading. Adjust for climate (heating/cooling degree days), occupancy hours, and activity type.

2. Verified Energy Savings

Definition: Reduction in energy consumption verified through measurement and verification (M&V) protocols.

Measure TypeTypical Savings RangePersistence (Year 5)M&V Complexity
Lighting (LED)40-70% of lighting95%+Low
HVAC Controls10-25% of HVAC70-85%Medium
HVAC Equipment15-35% of HVAC80-90%Medium
Building Envelope10-25% of heating/cooling95%+High
Comprehensive Retrofit25-45% of total75-85%High
Industrial Process8-20% of process80-90%High
Verification LevelMethodAccuracyCost
IPMVP Option AKey parameter measurement±15-25%Low
IPMVP Option BFull system measurement±10-15%Medium
IPMVP Option CWhole building calibrated±5-10%Medium-High
IPMVP Option DCalibrated simulation±8-12%High

3. Demand Response Capacity

Definition: Load reduction capability that can be reliably dispatched during grid events.

SectorTypical DR CapacityResponse TimeDuration Capability
Commercial HVAC15-30% of peak5-15 minutes2-4 hours
Industrial Process10-40% of load15-60 minutes1-4 hours
Data Center5-15% of load5-30 minutes1-2 hours
Refrigeration (Cold Storage)30-60% of load5-15 minutes4-8 hours
Water Heating50-80% of load<5 minutes4-12 hours
EV Charging40-90% of load<1 minuteUnlimited

Firm vs. interruptible: Not all DR capacity is equally reliable. Measure both maximum capability and firm (guaranteed) capacity under various conditions.

4. Load Flexibility Index

Definition: Percentage of total load that can be shifted or curtailed without operational impact.

Building TypeShiftable LoadCurtailable LoadTotal Flexibility
Office (Standard)15-25%10-20%25-40%
Retail10-20%8-15%18-30%
Industrial (Batch)25-50%15-30%40-70%
Industrial (Continuous)5-15%5-15%10-25%
Data Center10-20%5-10%15-25%
Cold Storage35-60%20-40%50-80%

Thermal mass opportunity: Buildings with significant thermal mass (concrete, water storage) can shift HVAC load for hours without comfort impact. Pre-cooling/pre-heating unlocks this flexibility.

5. Peak Demand Reduction

Definition: Reduction in maximum demand (kW) during grid peak periods or facility billing peaks.

StrategyTypical Peak ReductionPayback Period
Demand Limiting Controls8-18%1-3 years
Thermal Storage (Ice/Chilled Water)20-40%4-8 years
Battery Storage15-50%6-12 years
Load Scheduling10-25%<1 year
Distributed Generation20-50%5-10 years

Demand charge savings: For commercial/industrial customers, demand charges can represent 30-50% of electricity bills. Peak reduction strategies often have faster payback than efficiency measures.

6. Grid Carbon Reduction from Flexibility

Definition: Emissions avoided by shifting consumption from high-carbon to low-carbon grid periods.

Grid TypeShift PotentialAnnual Emissions Reduction
High Renewables, Constrained4-8 hours/day15-35% of electricity emissions
Variable (Wind-Heavy)Weather-dependent10-25% of electricity emissions
Peaking GasAligned with peaks5-15% of electricity emissions
Baseload-DominatedLimited3-8% of electricity emissions

Real-time signals: Platforms like WattTime, Electricity Maps, and Tomorrow provide real-time marginal emissions data enabling carbon-aware load shifting. Organizations using these signals report 15-30% additional carbon reduction beyond efficiency.

7. Program Participation Rate

Definition: Percentage of eligible loads or facilities participating in efficiency/DR programs.

Program TypeTypical ParticipationLeading Programs
Utility Rebates15-30% of eligible40-60%
Performance Contracts5-12% of eligible20-35%
Demand Response (Paid)8-18% of eligible35-55%
Time-of-Use Tariffs20-40% of eligible60-80%
Automated DR (OpenADR)3-10% of DR capacity25-45%

Barriers to participation: Program complexity (35% cite), upfront costs (28%), uncertainty about savings (20%), and split incentives (17%). Streamlined programs with guaranteed outcomes achieve higher participation.

8. Cost of Saved Energy (CSE)

Definition: Program cost per unit of energy saved over measure lifetime.

Measure CategoryCSE Range ($/MWh)Comparison: New Supply
Behavioral Programs$5-20Gas: $40-80
Lighting Retrofit$15-35Solar: $25-50
HVAC Controls$25-50Wind: $20-40
HVAC Equipment$40-75Grid Average: $50-100
Building Envelope$50-100Storage: $80-150
Industrial Process$20-60-

Efficiency as resource: CSE under $50/MWh is competitive with or cheaper than new generation. Utilities and grid operators increasingly treat efficiency as a supply resource in integrated planning.

What's Working in 2024-2025

Automated Demand Response (OpenADR)

Automated systems that receive grid signals and adjust loads without human intervention achieve 3-5x higher response reliability than manual programs. Adoption is accelerating: California now has 2+ GW of automated DR capacity.

The technology enables new value streams. Buildings with OpenADR capability can participate in frequency regulation, capacity markets, and real-time energy markets—stacking multiple revenue sources.

Pay-for-Performance Efficiency

Traditional rebate programs pay for installed measures regardless of actual performance. Pay-for-performance models (metered efficiency) pay for verified savings, shifting risk from utilities to implementers. These programs achieve 20-30% higher actual savings than deemed savings approaches.

Key enabler: advanced metering infrastructure (AMI) and M&V 2.0 platforms that automate savings verification at scale.

Grid-Interactive Efficient Buildings (GEBs)

The Department of Energy's GEB framework combines efficiency, flexibility, and automation. Buildings designed to GEB specifications can reduce energy use 20-40% while providing grid services worth $50-150 per kW-year.

Early implementations show that integrated approaches—where efficiency and flexibility are designed together—outperform sequential approaches (efficiency first, then add flexibility).

What Isn't Working

Split Incentive Persistence

Building owners who don't pay energy bills lack motivation to invest in efficiency. Tenants who pay bills can't modify building systems. This "split incentive" affects 40-50% of commercial buildings. Green lease clauses that share savings between owner and tenant help but remain rare (<10% of leases).

M&V Complexity and Cost

Rigorous savings verification costs 3-8% of project value—often exceeding implementer margins. This creates incentive to simplify M&V, which reduces accuracy and confidence in results. New automated M&V approaches promise 10x cost reduction but are not yet widely adopted.

DR Program Fatigue

Frequent demand response events (>30 per year) cause participant fatigue and declining response. Programs with aggressive dispatch exhaust participant willingness. Sustainable programs limit events to 20-30 per year with predictable scheduling.

FAQ

Q: How do I prioritize between efficiency and demand response investments? A: Efficiency first—reducing total consumption lowers both costs and emissions. Then optimize timing of remaining consumption through demand response. However, if grid flexibility payments are high (>$100/kW-year), DR investments may have faster payback. Model both together for portfolio optimization.

Q: What's the business case for automated demand response? A: Automated DR provides: (1) utility/ISO payments ($30-150/kW-year); (2) demand charge reduction (10-30% of demand costs); (3) time-of-use bill optimization (5-15% electricity cost reduction); and (4) carbon reduction from load shifting. Combined value often $100-300/kW-year for highly flexible loads.

Q: How reliable are deemed savings versus measured savings? A: Deemed savings (based on measure counts and engineering estimates) typically overstate actual savings by 15-30% for complex measures. Measured savings (Option C/D M&V) are accurate to ±5-15% but cost more. For single measures in stable conditions, deemed savings are reasonable; for comprehensive retrofits, measured approaches are essential.

Q: How do I address split incentives in leased buildings? A: Options include: (1) green lease clauses sharing savings between owner and tenant; (2) on-bill financing where utility recovers costs through bills; (3) PACE financing attached to property, not tenant; (4) operating expense caps that give owners incentive to reduce base-year costs. No single solution works everywhere.
