Operating Reserve Charges in PJM • First and foremost, operating reserves are unknown when a trader enters in a transaction. Thus there is no way for me to evaluate that risk for my traders upfront. • The numbers above are telling because they demonstrate that in the first five months of 2013 there was a 55% increase in operating reserves. No analysis of historical data could have predicted this volatility. • The rate for East Deviations has been has high as $32. Higher than the LMP.
Who Is Receiving Operating Reserve Charges And The Impact On the Market According to the PJM Independent Market Monitor • The top 10 units receiving Operating Reserve Credits received 40.3% of all credits. • The top 10 organizations received 86.9% of all credits. Incremental offers of Energy /Dec have been decreasing in PJM. • INCs have decreased 28.2% in 2013 and 12.8% in 2012 • DECs have decreased 21.6% in 2013 and 11.4% in 2012
Problems with Current Locational Marginal Pricing • Currently Energy prices are being calculated through the Security Constrained Economic Dispatch (SCED) • SCED is the primary engine for determining Energy and Reserve product clearing for both Day Ahead and Real Time markets. • A drawback of SCED is that it does not allow certain Demand Response and Fast Start Resources to set price. • SCED also may not capture Start up and Shut down cost and No-Load cost. • The cost are recouped in the form of Operating Reserve Charges.
A Potential Solution: Extended LMP • Extended LMP is a new computational method • It allows Fast Start Resources and Emergency Demand Response that are either scheduled at limits or are offline to set price. • Both Start-Up/Shut-Down Offer costs and No-Load Offer costs will be reflected in the LMPs and MCPs set by Fast Start Resources. • The price will more accurately reflect actual system conditions.
Benefits of Extended LMP • Extended LMP calculates price using incremental increase in energy that takes into account unit commitment cost. • Extended LMP minimizes the amount of Operating Reserve cost need to make generators whole. • Extended LMP adds transparency to Uplift cost allowing market forces to react. • Extended LMP cuts down on contentious cost allocation discussions in the stakeholder process.
