New York Independent System Operator

Welcome


New York Independent System Operator

(Pre-NYISO) Regulated Market

• Physical contracts

• Regulated industry

• Cost Based System

• Two Party Deals

• Bundled Services

• Members sell Firm Transmission Capacity

• Losses

• Scheduled in MWH’s (megawatt hours)

• Fixed %

• Balanced (hourly or Monthly)


New York Independent System Operator

NYISO De-regulated Wholesale Electric Market

• Financial

• Deregulated

• Price Based System

• Unbundled Services

• NYISO OATT (Open Access Transmission Tariff)

• Marginal Losses paid in $’s

• Balanced every 5 minutes

• Transmission Congestion Contracts (TCC’s)


New York Independent System Operator

New York Independent System Operator


New York Independent System Operator

New York Independent System Operator

• A not for profit corporation established to:

• Maintain safety and reliability of New

York State transmission system

• Schedule and coordinate power transactions


New York Independent System Operator

New York Independent System Operator

• Provide open access to New York State

transmission system

• Provide non-discriminatory treatment for all

market participants

• Provide meaningful involvement by market

participants in the oversights of New York State

transmission system

• Act as a clearinghouse for transactions by

market participants


New York Independent System Operator

Load Serving Entity


New York Independent System Operator

Load Serving Entity(i.e. Freeport Electric)

• Responsible for providing energy, capacity and ancillary

services

• Retail customers liaison with NYISO

• Submits (schedules) forecasted retail loads for which it is

responsible to the NYISO two days ahead and five days

out

• Submits actual metered load data to the NYISO


New York Independent System Operator

Ancillary Services


New York Independent System Operator

Ancillary Services

• Ancillary Services – necessary to support the transmission

of energy from generator to loads, while maintaining

reliable operation of the power system

• Scheduling, System Contract and Dispatch

• Reactive Supply and Voltage Support

• Regulation and Frequency Response

• Energy Imbalance (mismatches between day ahead

schedules and real-time)

• Operating Reserve (back-up generation)

• Black Start (generators starting without outside electric

supply following a system blackout)


New York Independent System Operator

Locational Based Market Price


New York Independent System Operator

Locational Based Market Price

• The price of energy at each of the 11 zones of the

New York State Transmission System

• Equivalent to the cost to supply the next increment of

load in the zone

• Differences in LBMP reflect cost of transmission

associated with system congestion

• Price for NYISO transmission losses

• Energy imbalance charges


New York Independent System Operator

Day Ahead Market


New York Independent System Operator

Day Ahead Market

• Schedules the most economic units available

• Hour by hour load schedules and generator bids

• Accepted load schedules and generator bids

become forward contracts

• Prices locked in

• Sets congestion rents for Transmission

Congestion Contracts (TCC’s)

• Closes at 5:00AM the day before schedule

• Accepted bids posted at 11:00AM the day before


New York Independent System Operator

Hour Ahead Market


New York Independent System Operator

Hour Ahead Market

• Advisory – Generators only

• Projection of next hour prices

• Prices not locked in

• Transaction accepted are settled in Real Time

Market (RTM)

• Closes 90 minutes prior to the hour

• Looks ahead three hours

• Accepted bids posted 30 minutes prior to the hour


New York Independent System Operator

Real Time Market


New York Independent System Operator

Real Time Market

• Dispatches generation to serve the real time load

• Real-time computer program adjusts the output of

dispatched generators

• Final settlement for DAM and HAM schedules

where actual generation or sales differ from DAM)

• Operated to match actual load to available generation


New York Independent System Operator

Transmission Congestion Contract


New York Independent System Operator

Transmission Congestion Contract

• A financial hedge of transmission congestion, (I.e.

protection from congestion charges)

• Financial equivalent of firm transmission rights

• Allows holder to collect congestion rent from the

NYISO associated with transmitting power from

point of injection to point of withdrawal

• Associated with the physical capability of

transmission system


New York Independent System Operator

Installed Capacity


New York Independent System Operator

Installed Capacity

• Available resources which ensure that the probability

that load exceeds available generation occurs no

more than one day in 10 years

• ALL LSE’s (load serving entities) in New York must

maintain ICAP (locational ICAP)

• Each LSE is assigned an ICAP requirement

predicated on its peak demand coincident with the

transmission District peak demand

• If a LSE does not fully meet its ICAP requirement, it

must purchase the deficiency through NYISO

auctions
