What is Energy Efficiency?


Efficiency versus ConservationEnergy Conservation:Doing with less of a service in order tosave energy– Using less energy and probably gettingless of a result– Example: Turning down the thermostat toget less heatingEnergy Efficiency:The use of less energy to provide thesame or an improved level of service– Using less energy to perform the samefunction– Example: A more efficient furnaceExample: Turning street lightsoff versus installing efficientstreetlight lamps and controlsLBNL presentation for SD PUC August 2013 4

Documenting Energy Efficiency Savings1. Verify potential to generate savings2. Determine lifetime savingsExample: Lighting RetrofitPotential to save:Before: 60 Watts/fixtureAfter: 13 Watts/fixtureSavings:Determined based on operatinghours and lifetime of lampsExample: New CarPotential to save:Before: 10 MPGAfter: 50 MPGSavings:Determined based on how manymiles driven and for how manyyearsLBNL presentation for SD PUC August 2013 7


Why do Energy Efficiency?• Has already done a lot to reduce wasting of energy• Is relatively cheap—reduces investment requirements forsupply-side resources:» Lower generation, transmission, distribution capitol costs» Lower fuel and other operating costs» Reduced risk and exposure to market volatility• There are plenty of opportunities• Not a limited resource—new technologies and strategies• Can be quickly implemented• Can be targeted, modular, manageable• Diversifies resource portfolios/increases system reliabilityLBNL presentation for SD PUC August 2013 9


EE Reduces a Utility’s Cost to Serve• EE avoids the need for newgeneration additions whichreduces capitalexpenditures• EE reduces total sales andpeak demand whichreduces energy productioncostsCase 2018 2019 2020 2021 2022 2023 2024 2025 2026 2027 2028 2029 2030 2031 2032BAU P P M P M M P PMod.

Two Comments on Financial Impacts• Impact on Non-Participants:• Rates, at least in short to medium term, probably go up• Program participation rates are a key aspect of this customerequity issue – bigger programs and more inclusive programdesigns result in more participants – fewer non-participants• Impact on Utilities: Since EE defers the need to buildmore power plants, fewer capital dollars are spentand with lower sales:• Utility revenues between rate cases can be lower thananticipated• Potentially reducing utility profits and shareholder returns• Quantifying the participant, non-participant and utilityimpacts requires South Dakota specific analysesLBNL presentation for SD PUC August 2013 13


Non-Energy Benefits of Energy Efficiency• Virtually all energy efficiency programs have objectivesassociated with reducing energy use and costs• However, there is a wide range of other non-energybenefits (NEB) that come from energy efficiencyactivities—these can negative or positive• NEBs can be categorized as those accruing to:− Utilities (energy providers)− Society as a whole− Individual participants• For consumers, these NEBs may actually drive theirinterest in efficiency investmentsLBNL presentation for SD PUC August 2013 14


Non-Energy Benefits: Utility & SocietalValueHedge valueReduced commodity pricesresulting from reduced demandEasing electricity/gasdistribution/transmissioncapacity constraints andenhancement of reliabilityAvoided transmission anddistribution capital andoperating costsEnvironmental benefitsCustomer bill collection andservice-related savingsCan provide access to energysavings opportunities for allmarketsEconomic developmentImpactReduction of consumer exposure to volatility in electricity/gas commodity costsReduction in aggregate demand puts downward pressure on wholesale market electric andgas commodity prices(localized) Reduced line losses, voltage support (reliability), and power qualityimprovementsReduces the likelihood of gas curtailments, and may eliminate or delays the need for localcapital intensive system upgrades(localized) Particularly valuable in areas with high energy use, high demand growth, and/orconstrained distribution systemsProduction and consumption of electricity/gas has environmental impacts.Avoiding shut-off notices, shutoffs/reconnects, and carrying costs on arrearagesVirtually all consumers can participate in energy efficiency programsEE programs can support greater net job growth than electricity/ gas supply and deliveryLBNL presentation for SD PUC August 2013 15


Non-Energy Benefits: Jobs• Direct. Jobs are in firms that are actually receivingthe efficiency program dollars and doing the energyefficiency work• Indirect. Jobs in firms supplying goods and servicesto energy efficiency firms• Induced. Those created by the demand generated bywage and business income from energy efficiencyinvestments and by energy bill savings.LBNL presentation for SD PUC August 2013 16


Non-Energy Benefits: Participant Benefits• Indoor air quality improvements, improved comfort (e.g., quality of light,less noise, fewer drafts, better building temperature control), higherproductivity and lower rates of absenteeism through better-performingenergy using systems (e.g., ventilation, building shell, lighting)• Reduced equipment operations and maintenance (O&M) costs because ofmore efficient, robust systems (although more complex systems couldrequire more maintenance)• Water and wastewater savings• Positive personal perceptions (e.g., “green,” environmentalconsciousness) and for commercial businesses and public entities,improved public perceptions and the ability to market products and tenantleases• Avoided capital cost for equipment or building component replacementswhose capital costs can be paid from savingsLBNL presentation for SD PUC August 2013 17


What are the Barriers to EnergyEfficiency?


Barriers to Energy EfficiencyEfficiency’s Version of the Tragedy of the CommonsEfficiency is a great costeffectivemechanism forsociety to save energy andother NEBs, but…there isa paradox ….It is not necessarily thechoice that individualenergy users makebecause of various marketbarriersLBNL presentation for SD PUC August 2013 19


Barriers to Energy Efficiency• Front-end investment requirements• Principal agent problem (property owner/tenant)• Lack of information and understanding of benefits (and risks)• Transaction costs• Lack of knowledgeable contractors, suppliers, etc.• Uncertainty in documenting benefitsLBNL presentation for SD PUC August 2013 20


Barriers to Energy EfficiencyExamples of issues in different marketsInstitutional/Public SectorBuildings− Large backlog of deferred capitalinvestments− Lack of financial resources− Lack of people resourcesCommercial Businesses− Split incentive problem− Lack of interest even in long tenancysituations since energy costs representsmall percentage of business costsResidential− Poor: not able to make investments− Middle class: lack financing− Well-off: energy costs represent a smallportion of disposable income so not thatinterested− Split incentive problem• Tenants pay energy bills• No incentive for owner improvementsIndustrial− Short investment horizon (1-3 yearpaybacks sought)− Energy costs can represent smallpercentage of business costsLBNL presentation for SD PUC August 201321


What are the Types of EnergyEfficiency Programs?


Energy Efficiency ProgramsSavings Hierarchy for Most EE Programs• Fundamental savings unit aremeasures—equipment or strategy• Projects are coordinated activities toinstall one ore more measures at a facility• Programs are collections ofsimilar projects that are intendedfor a specific market (adescribable group of customers)• Portfolios are multiple programinitiatives in specific marketsectorsLBNL presentation for SD PUC August 2013 23


Energy Efficiency ProgramsPublic Mechanisms and Regulatory Approaches—Voluntary and Mandatory• Voluntary Programs− Down-market: customer rebates− Mid-market and up-market: contractor and manufacturerincentives− Education, technical assistance and training programs• Mandatory Programs− Building codes− Appliance standards− Energy efficiency resource standardsLBNL presentation for SD PUC August 2013 24


New Construction and Retrofits• New Construction – more efficient than what wouldhave been built• Retrofits - two kinds of measures:– Replace on burnout = replace equipment whenexisting equipment fails– Early replacement = replace equipment before theend of the useful life of existing equipmentLBNL presentation for SD PUC August 2013 25

What are the Metrics for Success?LBNL presentation for SD PUC 27 August 2013


Metrics for EE ProgramsTypical Metrics and GoalsEnergy Benefits• Total savings for a project,program, or portfolio• Total savings for a State• Energy use indices—e.g.,energy consumption per capitaor per gross state product• Annual and lifetimeCost Effectiveness• Net Economic Benefits• Costs per unit of savedenergy—administrator costsConsumer Benefits• Bill reductions/increases• Rate reductions/increasesOther Benefits• Stability of energy markets,national security, etc.• Avoided T&D or generationinvestments• Creation of private sectormarket of energy efficiencyservices and products—jobcreationLBNL presentation for SD PUC August 2013 28


Why Evaluate?• Document impacts. Document the energysavings of projects and programs in order todetermine how well they have met their goals;e.g., has there been a good use of the investedmoney and time? Provide PROOF of theeffectiveness of energy management.• Resource Planning. To support energyresource planning by understanding thehistorical and future resource contributions ofenergy efficiency as compared to other energyresources. Provide data to support efficiency asa reliable resource.• Understand why the effects occurred.Identify ways to improve current and futureprojects and programs as well as select futureprojects. “You can’t manage what you don’tmeasure” and “Things that are measured tendto improve.”LBNL presentation for SD PUC August 2013 31

What are Major EfficiencyPolicy/Regulatory Issues in the US?


EE Policy/Regulatory IssuesBroad policy and market context issues:• A persistent economic downturn may impact the ability of EEadministrators to meet savings targets as well as the politicalfeasibility of increasing ratepayer funding for EE programs• Low natural gas prices reduce the avoided energy forecast and theheadroom for cost-effective EE, as well as participant interest• The effect of new Federal appliance and lighting efficiency standardson the remaining market potential for voluntary EE programs• EE programs can be part of the compliance solution for retiring coalfiredunits—how much reliance on EE vs. supply-side options?LBNL presentation for SD PUC August 2013 41


EE Policy/Regulatory IssuesEE Program funding and regulatory oversight issues:• Funding levels and short-term rate impacts associated with large-scaleenergy efficiency implementation• Innovative program designs to reach deeper and broader savings inorder to achieve goals significantly beyond current achievement –increase customer participation• Sustainable EE business models to motivate utilities to participate in apositive manner - utilities’ earnings capabilities not hindered bycustomer efficiency with opportunities to receive additional earnings forexcellent performance• Efficiency is treated and analyzed as an actual resource• Near-term, shortage of trained personnel in the energy efficiencyservices sectorLBNL presentation for SD PUC August 2013 42


EE Policy/Regulatory IssuesEE Program focus and design issues:• Who pays vs. program spending (equity objectives)• Maximize cost-effectiveness vs. opportunities for all customers toparticipate• Targeted to under-served markets & utility customers• Program administration costs vs. other costs (e.g., incentives)• Types of programs• Retrofit vs. “lost opportunity”• Information/education vs. “subsidies” (incentives)• Natural gas and electricity efficiency interactions• Role of utility versus private sector service and product providers• Balance activities with near and long-term impactsLBNL presentation for SD PUC August 2013 43


Natural Gas and Electricity Efficiency –Partners or Adversaries?Good:Bad?:• Packaging electricity and naturalgas efficiency measures can bebeneficial for consumers –residential, commercial andindustrial• With low natural costs (and thedifficulty of showing costeffectivenessof natural gasmeasures), evaluating costeffectivenessat theElectricity/natural gas portfoliolevel can help justify natural gasmeasures• Competition and potential for fuelswitching between natural gas andelectric only utilities can createunintended consequencesOpportunity:Coordinated, joint delivery ofservices can:– Reduce usage for both electricityand gas– Is more cost-effective withreduced transaction costsLBNL presentation for SD PUC August 2013 44


Role of Program Administrator andOther Market ParticipantsCreating vibrant energy efficiency services industry involves regulatordefining roles of administrator and implementers• Distribution utilities are in unique position to influence efficiencyactivities− Substantial customer reach—field representatives− Customer perception as trusted advisor: objective− Access to customer bills—financing, credit-worthiness− Information on customer energy usage patterns• Private sector energy efficiency services industry may be inhibited ifutilities provide one-stop source of information, financing, technicaladvice, program delivery & implementation− As relationships between efficiency service providers and customersstrengthen, customer/utility bond shifts to a market driven by private sector− Regulators can critically review utility role as primary programimplementersLBNL presentation for SD PUC August 2013 45

Program focus: near-term savings vs.long-term market impacts• Resource acquisition. The primaryobjective of this program category is todirectly achieve energy and/or demandsavings, and possibly avoid emissions,through specific actions.• Market transformation (MT). The primaryobjective of this program category is tochange the way in which energyefficiency markets operate (e.g., howmanufacturers, distributors, retailers,consumers, and others sell and buyenergy- related products and services),which tends to result in more indirectenergy and demand savings.• Multiple objectives. Programs can includesome or all of the above-listed objectives.MARKETPENETRATIONYEARSLBNL presentation for SD PUC August 2013 47
