Setting the Stage
Terminology Energy consumption The total amount of energy or power used. Measured in kilowatt-hours (kWh) Demand the immediate rate of consumption; how fast or the rate at which energy is consumed. Measured in kilowatts (kW) Load Shape Graph of the variation in the electrical load (demand) versus time. 11
Demand Side Management Energy Conservation Load Shifting Behavioral; reduction in energy Energy use is shifted to different consuming devices times of the day Energy Efficiency Peak Management Demand Side Reduce energy use (kWh) by Manage loads to reduce overall Management using more efficient equipment. demand Distributed Generation Demand Response Self generation of power Short-term reduction in demand in response to a request or signal 12
Demand Response Changes in electric usage by end-use customers from their normal consumption patterns in response to changes in the price of electricity over time, or to incentive payments designed to induce lower electricity use at times of high wholesale market prices or when system reliability is jeopardized.

Energy Use and Greenhouse Gas Emissions
The “Marginal” Generator • Natural gas provides most of California’s “flexible” generation • When electricity demand changes, natural gas plants ramp up or down to meet demand https://www.iea.org/etp/tracking2017/naturalgas-firedpower/
Marginal GHG Emissions • Marginal emissions consider which Marginal GHG Emissions Rates 0.6 powerplant turned on or off in response to changing load 0.5 • Marginal emissions 0.4 increase/decrease depending on the GHG Emissions (kg/kWh) emissions rate of the responding 0.3 power plant • Not all hours are created equal 0.2 0.1 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 Hour 17

Integrating Energy Efficiency & Demand Response
Why Energy Efficiency and Demand Response? Save/Earn Money Reduce utility bills and receive compensation for participating in demand response events Reduce Pollution and Greenhouse Gas Emissions Use less electricity, especially at times when it is more polluting Improve Grid Reliability Reduce electricity demand on the electrical grid, especially during times of peak demand 20
Some Technologies can provide both EE and DR Example - HVAC Units • Remotely-controllable variable speed drives; thermal energy storage systems. 21
Case Study – Hotels Implementing EE and DR 22
Implemented EE measures, new sensors, load controls 23
Insight into and control over electricity use 24

AutoDR Workforce Development Project
Project Goals Advance the goals of AB 758 to 1 4 Increase economic opportunity in achieve energy savings in existing DACs through workforce development buildings 2 5 Achieve greater grid reliability & Support the deployment of AutoDR lower costs for CA ratepayers technologies 3 6 Develop a skilled workforce around AutoDR communications technology 27
Benefits of Participating in DR Reduced energy usage Improved grid resilience 3 1 Use less energy with Decrease potential strain more efficient lighting & on the grid by using HVAC controls energy when it is more plentiful Benefits of DR Earn financial incentives Decreased GHG emissions 2 4 By participating in DR Using energy when events demand is lower, decreases our reliance on polluting peaker plants 28
Sample DR Programs by Customer Type IOU Customer CCA Customer DA Customer • PDP/CPP • CBP • PDP – must receive both generation & distribution • Base Interruptible • Base Interruptible from the utility • CBP • Wholesale Market • CBP – eligible to participate & receive AutoDR controls • 3rd Party Aggregation incentives (wholesale aggregation) • Base Interruptible – best suited to large C/I sites 29
AutoDR Incentive Programs SCE Express & PG&E FastTrack Incentive Programs • Express customers receive up to 100% of the AutoDR incentive up front. • Incentive pays up to 100% of project costs. • Simplified incentive calculators. • Eligibility: • Offices under 100,000 sq. ft. • Facilities with 100 – 499kW maximum demand • Strategies including: Dimming Lighting, HVAC temperature resets, HVAC duty Cycling • AutoDR Custom programs available for large C&I and more advanced strategies. 30
