Performed on a 6-second basis through automatic generation control (AGC)
North American Electric Reliability Council (NERC) reliability requirement – tracked via CPS2 index
Full two-settlement for regulation
Regulation service will be scheduled and settled, nominally on a 5-minute basis

Current Key Issues - Regional Market Initiatives: Current Key Issues - Regional Market Initiatives Energy Markets
Elimination of pancaked through and out charges throughout the Northeast region
Improve the efficiency of inter-market energy trading – Coordinate energy dispatches between ISOs and move toward single area LMP dispatch efficiency and financial versus physical transactions (VRD-like concept)
Reduce risks for inter-market energy trading – Cross-border congestion hedges
Establish greater consistency of bidding protocols – Single point regional transaction entry
Coordination and compatibility of billing and settlements for regional trading
Capacity Markets
Regional ICAP trading improvements - greater market rules compatibility
Renewable resource valuation methods
RGGI Reliability Considerations: RGGI Reliability Considerations Supplemental commitments are often required to meet NOx requirements in NYC
Certain units on 115, 138 and 230 kV networks provide voltage support on underlying network (Western NY, Long Island)
11 of 66 Transmission Owner Applications of New York State Reliability Council Reliability Rules directly address the need for specific thermal units to meet reactive power support and local power system requirements
Dual-fuel units (gas/oil) are important during peak winter demand periods
Operating range flexibility is important

Wind Power Reliability Considerations: Wind Power Reliability Considerations Operational Issues:
Reactive power demands increase with increasing MW output (acts as an induction generator)
Dynamic response to power system faults
Potential regulation impact
Mitigation Strategies:
Voltage regulation at the Point-of-Interconnection, with a guaranteed power factor range.
Low voltage ride-through.
A specified level of monitoring, metering, and event recording.
Power curtailment capability.
Slide32: Current Market Rules for Intermittents In New York, intermittents existing as of 11/19/1999 and 500 MW of new resources are:
paid for all energy produced regardless of their Day-Ahead schedule (Imbalance Charges)
excused from paying penalties for generating at less than their basepoints (Under-Generation Penalties)
Wind and solar resources are paid for their capacity in a valuation based on historic capacity factors, adjusted for maintenance
Rule Changes Contemplated:
Adjust the manner in which intermittents are balanced against their Day-Ahead Schedules, Including Real-Time Payments for Delivered Energy
Adjust the Method Used to Measure the Capacity Value of All Generation
Including correlation of resource availability with system peak hours
Adjust the exemption from Regulation Penalties
How will the 500 MW “Exemptions” be applied?
RGGI Design and Electricity Market Intersection: RGGI Design and Electricity Market Intersection Allocation of allowances
If allowances must be purchased by suppliers, will the total cost be reflected in energy market offers?
If so, will the clearing price be such that the units are committed?
If allowance costs are not fully reflected in energy offers, will capacity prices increase?
What if costs are not recovered? Will we be faced with retirements of baseload units otherwise needed for reliability?
RGGI Design and Electricity Market Intersection: RGGI Design and Electricity Market Intersection Cap size
Regional, state-by-state allocations
Possible impacts are similar to those associated with handling of allowances, i.e., too tight a cap may result in units needed for reliability being uneconomic
Caps should be designed in a manner that shapes future performance without creating immediate financial problems for suppliers – this will have a ripple effect on new construction
Phased-in caps can signal new construction in a market-friendly manner
RGGI Design and Electricity Market Intersection: RGGI Design and Electricity Market Intersection Temporal Flexibility
Borrowing
Would be necessary in situations where reliability may otherwise be jeopardized (similar arrangement for NOx in 6 NYCRR 237-6.5f)
RGGI Design and Electricity Market Intersection: RGGI Design and Electricity Market Intersection Leakage
Uncertainty of supply from Ontario (~5 years out)
What is the impact on PJM commitment if only portions of the control area are subject to RGGI?
How will new coal facilities outside the RGGI region impact the overall program effectiveness?
RGGI Design and Electricity Market Intersection: RGGI Design and Electricity Market Intersection Implementation Timing / Phase-In
Consider predicted installed reserve margin
Need to keep in mind other scheduled and proposed regulations, the timing and cost of which create significant supplier uncertainty:
NY’s revised NOx (NYCRR 237) and SOx (NYCRR 238) rulemakings
Potential mercury rules
Water permits (outages for fish protection, etc.)
RGGI Design and Electricity Market Intersection: Concluding thoughts on cap-and-trade system
Needs to be flexible
Should be in a form that can be widely adopted in other regions, countries, etc.
Should, to the extent possible, adopt standard approaches in use elsewhere
Design should drive market solutions RGGI Design and Electricity Market Intersection
