Executive Summary

2011 Demand Response Availability Report 4

Executive Summary The North American Electric Reliability Corporation (NERC) 2011 Demand Response Availability report represents NERCrsquos independent view of reliability-related Demand Response availability and performance from April 1 2011 to March 31 2012

The 2011 report summarizes NERCrsquos Demand Response information It was prepared by NERC staff and the NERC Demand Response Availability Data System Working Group1

(DADSWG) under the direction of the Performance Analysis Subcommittee and Planning Committee

As the role of Demand Response increases both NERC and stakeholders need to analyze its performance to measure its benefits and impact on reliability In 2011 NERC began the first mandatory collection of reliability-related Demand Response information across 126 North American entities This includes enrollment and actual performance data from April 1 2011 to March 31 2012

2011 Summer Demand Response There were 527 deployments during the summer period (April 1 2011 to September 30 2011) and the maximum number of deployments (186 events) took place in July The summer period closed with a NERC-wide mean realized rate of 87 percent Table 2 in the 2011 Summer Demand Response Summary section depicts an overall snapshot of the enrollment and event information

In 2011 North America had the second warmest summer on record with an average temperature of 745degF2

PJM Interconnection (PJM) Electric Reliability Council of Texas (ERCOT) and ISO New England (ISO-NE) deployed reliability-related Demand Response to meet operating reserve requirements during July and August

The temperature resulted in June July and August having the largest number of events called as well as a high number of enrolled resources and capacity August had the largest enrollment out of the six-month reporting period with a total of 6930939 resources and 56362 MW

2011ndash2012 Winter Demand Response There were 138 deployments during the winter period (October 1 2011 to March 31 2012) and October and March were the most active with 25 deployments each The winter period closed with a NERC-wide mean realized rate of 79 percent Table 4 in the 2011ndash2012 Winter Demand Response Summary section depicts an overall snapshot of the enrollment and event information

Future Advancements Since there have been only two data collection periods issues may be identified that require review and modification of the reported data The data and analyses contained in this report

Going forward DADS will be a repository of historical Demand Response information for use in a wide range of applications for both planning and operation of the bulk power system (BPS) It will also provide technical support for those making reliability policy Performance metrics data will provide Load forecasters resource planners and analysts with a comprehensive database for North America

Introduction


Introduction Background

Demand Response is an increasingly important component in the overall portfolio of resources available to reliably meet the growing electricity demands in North America However both NERC and stakeholders need to measure Demand Response performance in order to gauge its benefits and impact on reliability Better performance measures will also help develop industry confidence in Demand Response use

NERC established a Demand Response Data Task Force (DRDTF) in early 2008 based on a recommendation from the Demand-Side Management Task Force (DSMTF) that industry needed a more systematic approach for collecting and quantifying Demand Response performance In its final report ldquoData Collection for Demand-Side Management for Quantifying Its Influence on Reliabilityrdquo3

The goal envisioned by DRDTF for DADS is the collection of Demand Response enrollment and event information so that industry can measure actual performance and the contribution to improved reliability Ultimately this analysis can provide industry with a basis for projecting contributions of dispatchable and non-dispatchable (eg price-driven) Demand Response supporting forecast adequacy and operational reliability The DADS specifications provide a consistent and timely basis for counting and validating the Demand Response contributions at the balancing area level

the DSMTF concluded a uniform system measuring delivered Demand Response performance together with a system to collect these performance data on an ongoing basis should be established by NERC The DRDTF specified the data collection requirements referred to as the Demand Response Availability Data System (DADS) and the metrics to quantify Demand Response performance

The DRDTF proposed to implement DADS in two initial phases Phase I and Phase II both support the collection of dispatchable Demand Response that is used to support BPS reliability The Phase I pilot program established a voluntary reporting system to collect dispatchable and controllable Demand Response event data while beta testing an internet-based system to receive the data submittals This pilot program launched in 2010 tested both the ability of wholesale and retail electricity organizations to provide the requested data and the ability of NERC systems to receive it Phase I used Excel spreadsheets to record data in a standard template Phase II data submittals included mandatory data requests to all electricity organizations that operate or administer dispatchable Demand Response programs

In December 2011 the DADSWG was formed with the NERC Planning Committee approval The DADSWG is continuing the efforts of the DRDTF by implementing a uniform approach to reporting and measuring Demand Response availability performance and other related reliability data

Introduction

7 2011 Demand Response Availability Report

NERC is reviewing the North American Demand Response enrollment and event information to provide the appropriate reliability performance trends to monitor No conclusions as to the absolute value of any of these metrics can be drawn at this time due to this being the first year of data collection

Further the metrics should not be compared averaged or added together between Regions or subregions as their BPS characteristics and market structures differ significantly in terms of resource mix system and market design Load characteristics such as the time of day and season of the year that Loads are available for control and simple physical geographic regulatory and climatic conditions Although all potential Loads may be curtailed during certain periods not all will be available at the same time Totaling the potential (registered) Loads as a measure of the amount that could be curtailed during a given time can distort actual availability values

The metrics in this report have been vetted by the industry via the DADSWG and are part of a preliminary set of metrics The DADSWG intends to continue developing metrics and reports from DADS to ensure that proper trending and reliability analysis is performed

If issues are identified from the first two reporting periods it could require a review and modification of the reported data The list of metrics will change over time In some cases the database for a given metric does not yet contain enough historical information to reveal useful information The selections here and in the future will be based on the ranking process which recognizes a metricrsquos potential for indicating impending reliability issues and performance

This activity is only in its early stage Identifying benchmarks for performance is a separate and future activity that may aid the industry in quantifying Demand Response reliability performance

Data Fields and Reporting

NERC collects Demand Response enrollment event and participation information to measure actual performance and its contribution to improved reliability Ultimately this analysis can provide industry with a basis for projecting dispatchable and non-dispatchable (eg price-driven) Demand Response that supports forecast adequacy and operational reliability NERC provides a consistent and timely basis for counting and validating the contributions at the different NERC functioning levels

Responsible Entities are required to submit DADS data These entities are defined as NERC registered entities that either dispatch a Demand Response resource or administer a Demand Response program product or service Responsible Entities for DADS data submittals are limited to the NERC registered entity types listed in Table 1

Introduction

The DADSWG requires data reporting for all Demand Response programs currently in effect However Responsible Entities are only required to register and submit data on Demand Response programs if

1 The program has been commercially in service for more than 12 months

2 The program has enrolled 10 MW or more of combined Demand Response resources Demand Response Program Categories

The DADSWG collects 3 reporting types for controllable and dispatchable Demand Response

1 Demand Response Reliability Event Participation in which resources are obligated over a defined period of time to provide Demand Response upon deployment by the appropriate Balancing Authority Load-Serving Entity Distribution Provider etc Reliability Event Data refers to emergency or contingency events not economic Demand Response deployments

2 Market Participation Programs in which Demand Response resources are scheduled to supplement generation based on market conditions or market offers Market Participation may cover any type of dispatchable Demand Resources that are scheduled or dispatched primarily on an economic basis

3 Ancillary Services Demand Response services as defined in FERC Order 888-A4

are those services necessary to support the transmission of capacity and energy from resources to Loads while maintaining reliable operation of the Transmission Service Providerrsquos transmission system in accordance with good utility practice Ancillary Services provided by Demand Response typically fall into two primary categories reserves and regulation

All Demand Response reporting types will be categorized as one of the following products

4 httpwwwfercgovlegalmaj-ord-regland-docsorder888asp

Introduction


1 Energy Demand Resources that are compensated based solely on Demand Reduction performance of specific amount of electricity during a Demand Response event typically the general energy market

2 Capacity Demand Resources that displace or augment generation for planning and operating resource adequacy with an obligation to deliver the capacity as energy during a fixed contract period

3 Reserve Demand Resources obligated to be available to provide Demand Reduction upon deployment by the system operator based on operating reserve capacity requirements that are established to meet applicable reliability standards

4 Regulation Demand Resources that increase or decrease Load in response to frequency changes during a specified commitment period Demand Resources providing regulation service are subject to continuous dispatch based on instructions from the system operator Provision of Regulation Service does not correlate to Demand Response Event timelines deadlines or durations

Introduction


Figure 1 illustrates the relationship between Demand Response resources and Demand-Side Management services including how Load reductions are implemented the ability to dispatch a given resource and the type of product or service that ultimately provides the MW While four products are identified as dispatchable Demand Response programs there are multiple services for any product in DADS The eight service types collected in DADS during Phase II reporting are Direct Control Load Management (DCLM) Interruptible Load (IL) and Critical Peak Pricing (CPP) with control Load as a Capacity Resource Spinning Reserves Non-Spinning Reserves Emergency and Regulation These services are shown in Figure 1 on the left side of the flow chart under the Dispatchable and Reliability banners Information on the Non-Dispatchable and Economic service types will be collected in Phase III and IV

Introduction


Reliability Event Details Reliability event data is reported for Demand Response services that are obligated to provide Demand Response upon deployment by the appropriate system operator Reliability event data refers to emergency or contingency events but not Demand Response deployments for economic purposes The event information includes the following attributes

bull Event Type and Reason

bull ProductService Type (Capacity or Reserves)

bull Zones (as defined by each Responsible Entity)

bull Advance Notification Date and Time Deployment Date and Time Reduction Deadline Time ReleaseRecall Time and Normal Operations DateTime

bull Dispatched Load Reduction (MW) (Those resources requested by the system operator not all of the resources registered in the program)

bull Number of Dispatched Resources

Note that with the current DADS reporting requirements when a Demand Response deployment is called resources in different local zones are counted as different events

Figure 2 provides the framework for the Responsible Entity to report Demand Response event timeline data on a consistent basis The figure represents the terms for timing events and the time durations applicable to the characteristics of a Demand Response event Certain criteriamdashAdvanced Notification Time and Normal Operation Timemdashare not captured by entities during a Demand Response event but the Deployment Reduction Deadline and Release date and time are collected for every event

2011 Summer Demand Response Summary



2011 Summer Reporting Period

This chapter focuses on the Demand Response enrollment and event information from the 2011 summer collection period which was Phase IIrsquos first reporting period The 2011 summer reporting period was from April 1 to September 30 2011 Table 2 depicts an overall snapshot of the enrollment and event information that was collected from those entities This includes actual Demand Response performance information across the entities that administrate Demand Response programs within North America

Entities that only had economic Demand Response programs were not required to report and NERC anticipates that the number of reporting entities may grow to over 200 once Phases III and IV are implemented

Table 2 Demand Response Enrollment and Event Information for 2011 Summer Reporting Period (April ndash September 2011)

Total number of entities reporting 80 Average enrolled resources each month 6461818

Total maximum enrolled resources (in August) 6930939 Average enrolled capacity (MW) each month 50919

Committed Demand Response Resources and Capacity Program enrollment data includes aggregated information about the number of resources (end-use customers ranging from individual residential Loads up to large industrial facilities) and registered Demand Response capacity (MW) on a monthly basis Figure 3 and Figure 4 depict the total number of committed resources and capacity each month These figures illustrate the number of resources and MW that could be called upon for use in reliability situations on a regional and NERC level Figure 3 and Figure 4 have been adjusted to eliminate the possibility of unintentional double-counting Demand Response resources8

8 There are two situations in which double-counting of Demand Response resources could occur

1 When aggregation occurs up to a Balancing Authority multiple enrollments for a given product category (Capacity Reserves Regulation or Energy) could occur and

2 When resources are jointly enrolled in multiple product categories within a single entity



Figure 3 2011 Summer Total Committed Demand Response Resources by Regional Entity (Includes NERC-wide Resources)

For all the Regions included in NERC the lowest volume of resources out of the six-month reporting period occurred in April and September April had 76 percent fewer committed resources and September had 25 percent fewer committed resources than the NERC average The largest number of committed resources out of the six-month reporting period occurred in June and August Compared to the NERC average June had 32 percent more committed resources and August had 67 percent more committed resources This is typically due to some Demand Response programs that are only active during the summer months For example Demand Resources for certain PJM programs can only be activated starting in June for the summer period

The RFC Region has the largest Demand Response capacity with an average of 3726 MW registered each month

Registered Demand Response as a Percentage of Total Internal Demand Figure 3 and Figure 4 above reemphasize the assumption that Demand Response typically has higher enrollment during the summer peaking months of June to August Figure 5 below illustrates the percentage of registered Demand Response capacity that could potentially be used to relieve transmission constraints during those peak months It compares each subregionrsquos peak Demand to registered Demand Response In the FRCC SERC RFC and NPCC Regions the potential of Demand Response to meet its Demand requirements is as high as or higher than 8 percent

Figure 5 2011 Summer Registered Demand Responses as a Percentage of Total Internal Demand

Approximate NERC subregional boundaries are used Calculations used to create the map represent the 2011 peak of registered subregional peak Demand Response as a percent of 2011 summer peak total internal Demand

Figure 6 below illustrates the different reliability service types that entities participated in for the 2011 summer reporting period For all the regions in NERC there was a total count of 261 service type programs The largest counted service types were Interruptible Load (IL) at 32 percent and Direct Control Load Management (DCLM) at 26 percent of total collected service types The lowest counted service types were Spinning Reserve at 4 percent and Regulation at 2 percent of total collected service types Note that programs vary in size and some Load enrolled in more than one program type this data does not reflect actual participation



As previously reported in NERCrsquos reliability assessments Demand Response providing ancillary services is still relatively new in most Regions Generally DCLM is a service type commonly supported by residential and commercial Loads while IL is commonly supported by large industrial Load The length of the Ramp Period is the key difference between these two service typesmdashDCLM will typically have a shorter Ramp Period with a 3- to 4-hour duration limit while IL is longer and may be sustained for several hours

Figure 6 displays the percentage of each Regionrsquos total internal Demand being met with Demand Response for the peak conditions observed during the summer Achieved MW reduction is critical in assessing the significance of Demand Response reliability Regions with a higher percentage may be more susceptible to issues if decreased customer participation in Demand Response occurs Participation and performance of these programs will be monitored over time to determine if these Demand Response programs can be counted on to relieve transmission constraints

Figure 6 2011 Summer Realized Demand Response Reduction as a Percentage of Total Internal Demand

Approximate NERC subregional boundaries are used Calculations used to create the map represent the 2011 peak of realized subregional peak Demand Response as a percent of 2011 summer peak total internal Demand

Figure 7 displays the percentage of enrollment capacity by Regional Entity Across the entire NERC footprint the largest volume of registered capacity by system type was IL at 24919 MW For all Regions included in NERC there was a total count of 282 service type programs The largest enrolled capacity of service types were IL at 52 percent and Load as a Capacity Resource at 25 percent of total collected service types The lowest capacity enrollment of service type was Emergency at 2 percent of total enrolled capacity



Figure 7 2011 Summer Service Type Enrollment Capacity (MW) by Regional Entity (Includes NERC-wide Resources)



For the 261 programs captured for the 2011 summer reporting period there were a total of 527 events10

Figure 8

The statistics vary by Region program characteristics and size but on average each program was called upon 254 times during the 2011 summer reporting period

shows the number of reliability-driven Demand Response events by Region that happened during the 2011 summer reporting period Out of 527 NERC-wide reliability events RFC had the most with 24 percent of the total and MRO had the least with 2 percent of the total

Figure 8 2011 Summer Total Number of Demand Response Events by Regional Entity (Includes NERC-wide Resources)

Figure 9 illustrates the number of deployed Demand Response programs per month by Regional Entity The summer months of June July and August had the most events while April and May had the fewest DADS summer reporting is April 1 through September 30 but several entitiesrsquo programs are only active when Demand is high during the months of June to August This

Registered Demand Response as a Percentage of Total Internal Demand Figure 13 and Figure 14 show that Demand Response typically had lower enrolled and committed resources during the winter months from December 2011 to February 2012

Figure 15 below illustrates the percentage of Demand Response capacity that has been registered compared with peak winter internal Demand by comparing each subregionrsquos peak Demand to registered Demand Response However not all registered MW are available for dispatch at any given time therefore dispatched amounts will generally be lower than registered amounts

In the FRCC SERC RFC TRE and NPCC Regions the potential of Demand Response to meet its Demand Requirements is as high as or higher than 8 percent

Figure 15 2011ndash2012 Winter Registered Demand Responses as a Percentage of Total Internal Demand

Approximate NERC subregional boundaries are used Calculations used to create the map represent the 2011 peak of registered subregional Demand Response as a percent of 2011 winter peak total internal Demand

Figure 16 displays the percentage of each Regionrsquos total internal Demand that is met with Demand Response for the peak conditions observed during the winter Achieved MW reduction is critical to assess the significance of Demand Response reliability Participation and performance of these programs will be monitored over time to determine if these Demand Response programs can be counted on to relieve transmission constraints



Figure 16 2011ndash2012 Winter Reduction Realization as a Percentage of Total Internal Demand from Demand Response

Approximate NERC subregional boundaries are used Calculations in the creation of the map represent the 2011ndash2012 peak of realized subregion Demand Response as a percent of 2011ndash2012 winter peak total internal Demand

Figure 17 illustrates the different reliability service types that entities participated in for the 2011ndash2012 winter reporting period For all NERC Regions there was a total count of 282 service type programs The largest enrolled capacity of service types were Interruptible Load (IL) programs at 50 percent and Load as a Capacity Resource programs at 26 percent of total collected service types The lowest capacity enrollment of service types were Emergency programs at 4 percent and Non-Spinning Reserve programs at 4 percent of total enrolled capacity

As previously reported in NERCrsquos reliability assessments Demand Response that provides ancillary services is still relatively new in most Regions Generally DCLM is a service type commonly supported by residential and small commercial Loads while IL is commonly supported by large commercial and industrial Loads The length of Ramp Period is the key difference between these two service typesmdashDCLM will typically have a shorter Ramp Period while IL is longer and may be sustained for several hours



Figure 17 2011ndash2012 Winter Service Type Enrollment Capacity (MW) by Regional Entity (Includes NERC-wide Resources)

For the 282 programs captured for the 2011ndash2012 winter reporting period there were a total of 138 events The statistics vary by Region program characteristics and size but on average each program was called on 089 times

Figure 18 shows the number of reliability-driven Demand Response events by Region during the 2011 winter reporting period Out of 138 NERC-wide reliability events SERC had the most with 49 percent of the total There were no Demand Response events in SPP

Significant Deployment Events


Significant Deployment Events Demand Response Contributed to Improved Reliability

PJM Energy Demand Response and Emergency Energy Alerts (EEAs) On Thursday July 21 2011 at 930 pm Eastern PJM issued a Maximum Generation Alert EEA Level 1 declaration for the PJM Mid-Atlantic region for Friday July 22 2011 High Loads were mitigated by commitment of additional generation and use of Emergency Demand Response The changes in Load wind production and reserves are shown in Table 6 The call for Emergency Demand Response resulted in the declaration of Emergency Energy Alert 2 at noon on July 22 2011 Emergency Demand Response of 2412 MW was realized on July 22 2011 Demand Response deployment is also shown in Table 6 The Demand Response Service Types14

Demand Response is an important component in the overall portfolio of resources required to reliably meet the increasing demand for electricity The example in Figure 23 shows that on July 22 2011 a day with high Load PJM deployed Emergency Demand Response The main benefit of Emergency Demand Response in operations is to help ensure resource adequacy while providing operators with additional flexibility in maintaining operating reliability

Figure 23 PJM Demand Response Primary Reserves and Load on July 22 2011

ERCOT Energy Demand Response and Emergency Energy Alerts (EEAs) On August 4 2011 at 145 pm Central ERCOT issued an EEA Level 1 because Physical Responsive Capability dropped below 2300 MW due to increasing Load decreasing wind generation and over 1000 MW of forced outages At 232 pm when Physical Responsive Capability dropped below 1750 MW and reached a low of 983 MW ERCOT declared EEA Level 2A This is shown in Figure 24 and Figure 25 As the situation continued to decline ERCOT declared an EEA Level 2B at 344 pm per operating procedures ERCOT deployed Emergency Interruptible Load Service (EILS) which are large industrial customers under contract to be interrupted under emergency situations At 405 pm a second EILS deployment for business hours was called from 400 pm to 800 pm

At 553 pm as the situation began to improve ERCOT moved to EEA Level 2A from EEA Level 2B and then to EEA Level 1 at 609 pm recalling EILS at that time The EEA Level 1 was cancelled at 652 pm No Firm Load was interrupted during this EEA event



Figure 24 ERCOT Peak Load Operations on Aug 4 2011

ISO-NE Maintaining Operating Reserve with Demand Response On July 22 2011 643 MW of active Demand Response was dispatched in conjunction with ISO-NErsquos operating procedure during capacity deficiency The performance of the active Demand Response was approximately 100 percent of the capacity supply obligation for those resources This allowed ISO-NE to effectively maintain 10-minute reserves on the system with the reduction of 662 MW of system demand and manage this event with Operating Procedure No 4 (OP 4)15

Effective preplanning and training of system operators resulted in a reliable outcome using ISO-NErsquos capacity and energy procedures to manage the higher-than-expected Loads and generation losses Overall existing procedures and processes allowed ISO-NE to manage the operation of the New England system in a reliable manner during summer 2011

The Demand Response Deployment started at noon and ended at 6 pm All Demand Response service types were Load as a Capacity Resource One hundred sixty-six resources with a total capacity of 1871 MW participated in the Demand Response deployment and the realized Demand Reduction was 636 MW16

Figure 25 System Load vs Forecast

16 Realized demand response data is reported as an hourly value to DADS ISO-NE uses a five-minute interval calculation and its

reported realized demand reduction is 644 MW

Enhancement Recommendations


Enhancement Recommendations Since there have been only two data collection periods issues may be identified that require review and modification of the reported data The data and analyses contained in this report are still in an early stage and the metrics collected now may change over time After review of 2011ndash2012 datasets the DADSWG recommends the following enhancements and implementations to provide clarity of the reported data and to ensure that the industry remains informed

1 DADS Reporting Instructions and Glossary Current and future functional entities need a detailed manual to standardize Demand Response reporting The DADSWG has discovered that some entities do not have a clear understanding of how to effectively report data using the online application webDADS This can be resolved by developing a detailed document outlining how to properly report Demand Response data which would include items such as metrics definitions and recommended methods The glossary in the reporting manual would eliminate ambiguity in the current DADS definitions

2 Seasonal Trending Analysis For the 2012 DADS report performance of Demand Response programs will be analyzed through trending methods The analysis will focus on the difference of how programs perform against the previous season ie winter 2011ndash2102 vs winter 2012ndash2013 This will give industry a clear indication of how registered programs are improving on a year-to-year basis

3 Metrics Enhancements Performance metrics are a key driver when measuring the reliability of an entityrsquos Demand Response program The DADSWG plans additional metrics for future reporting

4 Market Type on Programs Form in webDADS Currently entities do not have a method to indicate the market type for a registered program in webDADS The application will be enhanced to capture one of the following market types commercial industrial or residential

5 Further Segmentation This would add a lot of value both for reporting and planning purposes There are variations in the types of Demand Response especially between rate classes such as residential commercial and industrial Suggested segmentation includes

a In addition to listing resources by Regions break down the potential and dispatched Load available from each resource by

i Seasons ii Time of day

iii Day of the week iv Separate residential Load from commercial and industrial Load v Designate which Loads

1 Can be controlled by the System Operator 2 Depend on the Resource to curtail Load manually


3 Depend on a Curtailment Service Provider (CSP) vi Service Type

vii How much of the Demand Response registered and available is provided by behind-the-meter customer site generation

1 How many days and hours can this type of Demand Response be available

viii Annual Deferment Hours ix Ramp-up and ramp-down characteristics of each program

6 Drill Down and Report on More Specifics of the Various Programs in Aggregated Form

This will allow readers and planners to understand the amount of Demand Response that would be available on any given day or time of day

7 Develop State-by-State Summaries This will enable NERC to match up with reports from FERC

8 Performance Metrics Develop a set of Demand Response Key Performance Factors similar to the GADS Equivalent Availability Factor (EAF) Net Capacity Factor (NCF) and Equivalent Forced Outage Rate demand (EFORd) Some metrics ideas include

i Demand Response Potential () ndash The amount of Load registered with the entity that can be curtailed

ii Maximum Dispatched Amount in MW ndash The amount of curtailment that the System Operator called for and the denominator for determining the Realization Rate

iii Actual Load Reduction in MW during events iv Realization Factor ()
