On Site Energy – Interplay With pjm Demand Response Programs October 17, 2013Robert A. Weishaar, Jr. Harrisburg, PA – Columbus, OH – State College, PA Lancaster, PA – Washington, DC – Scranton, PA
PJM Demand Side Response • The purpose of PJM Demand Response is to enable Demand Resources under the direction and control of Curtailment Service Providers to respond to economic prices and/or emergency conditions • Demand Response can participate within the various PJM markets: • Energy • Day Ahead Market • Real Time Market • Ancillary Services • Synchronized Reserve • Regulation • Day Ahead Scheduling Reserve • Capacity • Offer into auction up to 3 years in advance
ENERGY MARKETS - PJMEconomic load response program ("ELRP") • All ELRP participation defined as: • Clearing in the Day-Ahead ("DA") Market • Dispatched by PJM in the Real-Time Market • ELRP participant or CSP must submit load reduction bid offer to PJM • Curtailment must clear in the DA market or be dispatched by PJM in real-time to be eligible for settlement revenue • Load reductions eligible to be paid full LMP if LMP is at or above the Net Benefits Price (a.k.a. threshold price) • Net Benefits Price expected to correlate to energy cost of an efficient combined cycle natural gas plant • Adjusts monthly • Price has ranged from approximately $23.00-$30.00/MWh
ENERGY MARKETS - PJMDefault Customer Baseline • A Customer Baseline ("CBL") is a proxy for what the load would have been absent the load reduction • All ELRP registrations require Customer Base Line ("CBL") certification • All customers must use a CBL with an error (relative root mean square error – "RRMSE") no greater than 20% • CBLs for customers with on-site generation are being determined mostly on a case-by-case basis • ELRP reduction is determined by the CBL minus the meter readings during PJM dispatched curtailment hours
ENERGY MARKETS - ELRPSummary and Caution • ELRP Revenue is determined by CBL Calculation • CBL Calculation represents a moving target • Presents some risk to curtailment amount • Could be manipulated to inflate ELRP revenue • Baseline manipulation viewed by FERC as manipulation of electric energy markets • Potential penalties of $1 million per day per violation • Daily decisions when/if to participate in the ELRP program must not consider impact to future CBLs • No payment for load reduction if LMP is less than Net Benefits Price • Historically, LMP has been greater than the Net Benefits Price about 50% of the time
Ancillary Services Markets • Synchronous Reserve Market • Paid for standby service • Emergency reserve that PJM can call quickly after a large generator suddenly trips off-line • Hourly payment just for being available to respond • 25 – 40 events typically occur annually • Total performance requirement of about 6 hours per year • Must reduce load/increase generation within 10 minutes when ordered by PJM • Requires 1-minute scan rate metering • Data submission within 24 hours • Consequences for non-performance
Ancillary Services Markets • Synchronous Reserve Market • Hourly market participation • Hourly synchronous reserve offer must clear the market to receive payment • Not all hours require PJM to procure Synchronous Reserves from Demand Resources or result in a clearing price greater than $0
Ancillary Services Markets • Regulation Market • Hourly market correcting for constantly occurring small load changes • Requires 5-minute response time • Requires both load reduction and load increase • Sub-metering permitted • Performance not measured based on change to AEP pull • Consequences for non-performance • Cannot simultaneously be participating in the Synchronized Reserves Market
Ancillary Services MarketS • Day Ahead Scheduling Reserve Market ("DASR") • Reserves are additional capacity above the expected load • The purpose of the DASR market is to encourage and incent generation and demand resources to provide the flexible capability to provide 30-minute reserves • If a Resource is called-on in Real-Time, it must respond in 30 minutes • Reserves are scheduled on a day-ahead basis in order to ensure that differences in forecasted loads and forced generator outages do not negatively impact system reliability • The Day-Ahead Scheduling Reserve Requirement is calculated on an annual basis and is set at 6.91% for 2013 • The DASR market clears simultaneously with the DA Energy Market • Limited revenue potential
Interaction of reserve market products • Resources can be capable of providing all three products: • Synchronized Reserve, Regulation, and Day-Ahead Scheduling Reserve • All three cannot be provided simultaneously, only two products, at most
Demand resources in the Capacity Market • Demand Resources can offer curtailment capability as a forward capacity resource three years in advance of delivery year • DR providers are required to provide the cleared demand response amount as capacity during the delivery year and will receive the capacity resource clearing price for this service • Must reduce load when requested by PJM All Call system within 2 hours of notification • Must provide customer-specific compliance and verification information within 45 days after the end of the month in which Load Management event occurred • Can participate in both ELRP and Capacity DR Programs • Note: Many aspects of RPM rules are being proposed to change, particularly those relating to DR
DR Performance Assessments (PENALTIES) • Three penalties are applicable to customers participating in RPM as Demand Resources ("DR") • RPM Commitment Compliance • Load Management Event Compliance • Load Management Test Compliance • PJM penalties applied on pro-rata basis and may result in forfeiture of expected revenue or the forfeiture of expected revenue plus a penalty • DR performance for on-site generation typically measured using Guaranteed Load Drop ("GLD") method
