Standard Market Design Standard Market Design Drivers for ISO-NEDrivers for ISO-NE

Implement Working Markets that have Congestion Management and Multi-Settlement, as quickly as possible Take advantage of software and lessons learned in

New England and elsewhere

Maintain allocation agreements negotiated by NEPOOL Participants

Benefits of the Standard Benefits of the Standard Market DesignMarket Design

Increase ability of Market Participants to make decisions affecting their load and resources Self-Scheduling External Transactions

Assure that the price reflects the resources actually dispatched Use “Ex-Poste” price calculations

Only units following instructions set price price based on actual, not predicted dispatch

Achieve a better balance between decisions made by software and operators

Operators need to assure that decisions made by software are reasonable

Page 5: Standard Market Design Technical Presentation April 18, 2001

Increased Ability of Market Increased Ability of Market Participants to Make DecisionsParticipants to Make Decisions

Previous design required that Market Participants turn all choices into prices and software would make decisions

SMD enables Market Participants to: Self-Schedule Generators Self-Schedule External Transactions Self-Supply Regulation Self-Supply Spinning Reserve Hedge Financially in Day Ahead Market and

bi-laterally

Page 6: Standard Market Design Technical Presentation April 18, 2001

Self-Scheduling of GeneratorsSelf-Scheduling of Generators

In Day-Ahead Market, units can be self-scheduled up to their maximum output

Units can adjust output in real-time (either higher or lower)

This is done by specific request, not by submitting a price

Page 7: Standard Market Design Technical Presentation April 18, 2001

7

Scheduling of External Scheduling of External TransactionsTransactions

External contracts can be self-scheduled in both Day-Ahead and Real-Time

Contracts willing to pay congestion will continue to flow Unless self-curtailed Physical curtailment needed

Unlikely as transmission costs increase, self-curtailment will occur

Dispatch should result in Economic Self-Curtailment

Page 8: Standard Market Design Technical Presentation April 18, 2001

Achieving better balance between Achieving better balance between software and operator decision-software and operator decision-makingmaking

Operator will review all constraints operative on the system and select those that affect dispatch

Pricing will be ex-poste, reflecting actual dispatch and operator entered constraints.

What the Standard Market What the Standard Market Design Doesn’t DoDesign Doesn’t Do

Change allocation in negotiated settlements in New England All financial congestion rights will be

auctioned Proceeds from auction will be allocated per

auction revenue rights in NEPOOL Agreement

Zonal pricing for load is retained

Transmission CongestionTransmission Congestion

ISO-NE energy market will use Locational Marginal Pricing (Nodal and Zonal Pricing) to manage transmission congestion

Energy market includes overlying trading hubs and zones to provide standard energy products for commercial markets

Energy market includes FTRs (Financial Transmission Rights) to allow Participants to manage congestion risk

Page 16: Standard Market Design Technical Presentation April 18, 2001

What is LMP?What is LMP?

Pricing method ISO-NE will use to … Price energy purchases and sales in ISO-NE Market Price transmission congestion costs to move energy

within ISO-NE Control Area

Physical, flow-based pricing system

Prices are based on How energy actually flows, NOT contract paths

LMP ModelLMP Model

Price of energy is based on actual operating conditions, as described by state estimator

Price of energy at each location will be calculated and posted on the ISO-NE website at five-minute intervals

Five-minute LMP values will be integrated at end of each hour; hourly value will be posted on website

Accounting settlements will be performed based on hourly integrated LMPs (after LMP verification procedure)

Page 19: Standard Market Design Technical Presentation April 18, 2001

LMP CharacteristicsLMP Characteristics

Based on … actual flow of energy actual system operating conditions

LMPs … are equal (except for losses) when transmission

system is unconstrained vary by location when transmission system is

constrained

How will ISO-NE use LMP?How will ISO-NE use LMP?

Generators get paid at generation bus LMP

Loads pay a zonal price, which is derived from the load bus LMPs

Transactions pay congestion charges equal to difference between source and sink LMPs

Page 22: Standard Market Design Technical Presentation April 18, 2001

22

LMP Verification ProcedureLMP Verification Procedure

Purpose - Ensure that LMP values are accurately and completely calculated for each of the 288 five-minute intervals of the previous operating day.

Procedure: Market Engineers review dispatcher logs, program error logs, input data timestamps and

LMP results for each interval. Recalculate or Replace LMP values as required Notify Settlements Department that the LMP results are verified and ready to use in

accounting. Post daily LMP file on web by noon next day

Page 23: Standard Market Design Technical Presentation April 18, 2001

What are Financial What are Financial Transmission Rights?Transmission Rights?

Financial Transmission Rights are …

a financial contract that entitles holder to a stream of revenues (or charges) based on the hourly energy congestion cost difference between the source and sink

Page 24: Standard Market Design Technical Presentation April 18, 2001

24

Allocation of FTRS in Allocation of FTRS in NEPOOLNEPOOL

In its June, 2000 order, FERC approved an auction of all Financial Transmission Rights, with the proceeds of the auction being allocated to the holders of Auction Revenue Rights

This proposal and allocation will remain as part of Standard Market Design

Page 25: Standard Market Design Technical Presentation April 18, 2001

25

Auction Revenue Rights Auction Revenue Rights AllocationAllocation

FTR Auction Revenue allocated to: Those paying for new transmission

upgrades to the extent additional FTRs are created

Those paying Congestion Costs Transmission Customers Congestion Paying Entities NEMA Load Serving Entities

Page 26: Standard Market Design Technical Presentation April 18, 2001

26

Why Do We Need FTRs?Why Do We Need FTRs?

Challenge: LMP exposes Market Participants to price uncertainty

for congestion cost charges During constrained conditions, ISO-NE Market

collects more from loads than it pays generators

Solution: Provides ability to have price certainty FTRs provide hedging mechanism that can be traded

separately from transmission service

Page 27: Standard Market Design Technical Presentation April 18, 2001

27

Characteristics of FTRsCharacteristics of FTRs

Defined from source to sink

Financially binding

Financial entitlement, not physical right

Independent of energy delivery

Constrained OperationsConstrained Operations

Transmission constraints can prevent use of “next least-priced generator”

Higher priced generators closer to load (on constrained side of limit) must be used to meet load

Cost expressed as “security constrained re-dispatch cost”

Capacity MarketCapacity Market

PJM has a Capacity Market Current market similar to New York and New England

markets PJM West will have an available capacity market (6%

reserves/day)

A Capacity Market is needed to: Assure sufficient capacity exists within the region to

meet reliability standards Compensate 10 and 30 minute Non-Spin Capacity

until a Non-Spin Market or Markets are developed

New England can develop its own Capacity Market that meets these objectives

Description of Regulation Description of Regulation MarketMarket

Regulation Optimizer (REGO) is run after energy schedules and LMPs in Day Ahead Market

Objective is to meet regulation requirements at least cost

Selection of DA regulation resources based on merit order ranking of Regulation Offers plus opportunity costs from hourly schedules and LMPs.

Page 67: Standard Market Design Technical Presentation April 18, 2001

67

Description of Regulation Description of Regulation MarketMarket

Opportunity cost is estimated as: |LMP-ED|*GENOFF, where LMP = forecasted hourly LMP at generator bus, ED = price associated with generator setpoint to

maintain full regulation, and GENOFF = MW deviation between economic and

regulation setpoints

RMCP = highest merit order price of designated resources, and sets a floor price for the R/T market
