APSC Workshop on DR and AMI
Overview
• DR/EE offerings
• Some limitations due to regulatory process
• Cost recovery and rate base
• Loading order and preference policies
• Conditions precedent
• How DR/EE May Be Considered
DR/EE Options
• Technology (equipment) for utility implementation of DR Digital Control Devices (e.g. for AC cycling) Smart Thermostats (e.g., White-Rogers, simple to complex) Two-way communications, e.g. Gulf Power TOU Pricing Energy Management System (EMS) applications TOU-based WattSpot web-based gateway services
• TOU pricing – like Gulf Power• Dispatchable DR –direct load control• “Rate-guard” service (price-triggered response from SPP)• Environmental dispatch (“soft dispatchable DR)
• “Turn-Key” DR handing of off management & control
• Fully-outsourced DR program
Limitations Due to Regulatory Process
• Bifurcated proceedings => separation of goals and responsibilities
• Short-term funding (e.g., for GRC funding of DR/EE)
• Lack of resource integration and full consideration of long-term contracts
• RTO/ISO responsibilities vs. state responsibilities RTOs/ISOs and utilities are about reliability,
balancing needs, and ramping – more focused on capacity needs
State planning proceedings focus more on long-term supply-demand balance, so may ignore ramping & capacity needs
Cost Recovery and Rate Base
• Traditional cost recovery of expense and capital costs In what proceeding, covering what time frame, for DR/EE Longer-term treatment recognizes long-term benefits
• Rate-base treatment DR/EE installation & capital costs are traditionally rate-
based With 3rd party contracting DR/EE assets can still be
owned by the utility Incentive Rate-or-Return (ROR) may be appropriate
• Financial implications for utilities Rate-base reductions for long-term DR/EE contracts lower
investment levels for G + T + D + environmental mitigation
Loading Order or Resource Preference Policies
• Benefits of changing the presumed preference for traditional supply–side resources Recognizes G + T + D + environmental + market
mitigation Recognizes DR/EE are environmentally beneficial CA policy recognizes these benefits & difficulty of
detailed cost-effectiveness given multiple benefits• Has relaxed need for formal cost-effectiveness if competitive RFP
procurement process is used
NC approach requires a specific amount of DR/EE…
• Environmental adders – create preference for DR/EE
• Cost-effectiveness with all benefits defined – similar result
North Carolina Utilities Commission Orders Re. Proposed Coal Plants & Green Power• One 800 MW state-of-the art coal plant approved
• Duke commitment to invest 1% of annual electricity sales revenue in energy efficiency and demand-side programs EE/DR to back out MW-for-MW retired coal plants
• Must account for actual load reductions realized
EE/DR need is contingent on system reliability need Collaborative workshops to commence
• Green Power authorized if $25,000 or more of Renewagle Energy Credits (RECs) are purchased and applied to renewable generation
Conditions Precedent to New Resources
• Conditions imposed on ComEd’s AMI rollout – WattSpot Make DR/EE cost effective by offering a menu
(scope)
• Ensure cost effectiveness and ratepayer benefits Require specific results (e.g., with Standard Practice
Tests)
• Locational Resource Adequacy Requirement
• Risk allocation using 3rd party contracts Pay-for-Performance Rigorous Measurement & Performance
3rd Party Risk with Fully Outsourced DR
• DR program risks include the following: Marketing, customer acquisition, and customer churn Hardware and equipment (warranty) Software upgrades and customer call center Operations and maintenance Measurement & verification Performance – dispatchable MWs when called upon Stranded investment (if not used)
• Customers and Utilities Can Be Free of These Risks Utah, ISONE, SDG&E, and PNM examples
How DR/EE May be Considered N. Carolina
• If at least one half of the 1% of annual electricity sales revenue was allocated to DR At $.05/kWh this may amount to about $1.3 B
annually. To ensure performance we recommend performance-
based DR with rigorous Measurement & Verification (M&V) to account for actual load reductions realized
This may depend on system reliability need and on use of a reference costs for capacity ($/kW-year)
• DR may qualify for Green Power RECs if M&V shows savings to reduce emissions, comparable to renewables?
How DR/EE May be Considered in Arkansas
• Use competitive RFP procurement process
• Ask for specific DR or DR/EE services to enable apples-to-apples comparisons
• Consider not just new baseload resources but retirement of old, inefficient, polluting facilities held for reserves
• Integrate benefits/costs of G + T + D + environmental + market price/mitigation + hedging/insurance/portfolio
• Design a menu to provide more DR/EE services, for more benefits, customer acceptance, and customer choice
• Place risks for customer acquisition, hardware, installation, performance, & financing on DR/EE providers
Fully Examine Plant Expansion and Deferral
• Define the menu of DR/EE needed to meet needs at least cost, taking account the shifts in uses of generation
• Compare reliability, ensure outage rates are comparable, and define both T&D deferral and environmental benefits
• Define lowest life-cycle cost peaking capacity, including flexibility, market price impact, & market power mitigation
• Consider the flexibility benefits with DR/EE during the power plant planning and construction cycles Plant is lumpy, may be partially stranded, requires T&D DR/EE is not lumpy, can be increased/decreased based on
locational needs, does not require T&D
• Compare the hedging/insurance benefits & costs of both
