Need for 5-mn Settlement
On September 17, 2015, FERC issued an order requiring RTOs to implement 5-minute RT settlement
RTOs that are currently using 5-mn RT settlement:
– NYISO (Starting in 1997)
– SPP (Starting on 3/1/2014)
– CAISO (Starting on 5/1/2014)
RTOs that will implement 5-mn RT settlement:
– ISO-NE (Q1, 2017)
– MISO (Q4, 2017, ??)
– PJM (Q4, 2017, ??)

Pros and Cons for Implementing
5-mn Settlement
Advantages for using 5-mn settlement
– Line up RT settlement with RT dispatch More accurate payments for generators, especially during periods with LMP spikes
– Provide more incentives to generators to follow RTO 5-mn dispatch instructions Pay for performance
– Minimize make-whole payments
Disadvantages for using 5-mn settlement
– Need 5-mn meter data
– Increase volume of settlement data by a factor of 12
– Require upgrade in bid-to-bill IT infrastructure

Key Impacts of 5-mn Settlement
on your Bid-to-Bill IT Infrastructure?
Energy-Accounting & MDMA Functions: Big Impact
– Upgrade metering system to support 5-mn granularity
– Submit & Validate 5-mn Meter data for selected generators
– Modify Data Interfaces to Import 5-mn Meter Data
– Increase in meter data volume (12 x increase) Need to upgrade Energy-Accounting software
Settlement Validation & P&L Calculations: Big Impact
– Changes in 20-40 RT charge codes from Hourly to 5 mn
– Changes in RT make-whole payment calculations from Hourly to 5 mn
– Increase in settlement data volume (12 x increase) Need to upgrade IT infrastructure to perform shadow-settlement and validate RTO settlement
Invoicing Workflow: Small Impact
– Settlement calendar and invoicing workflow will remain the same
8Copyright 1997-2016, Power Costs, Inc. All rights reserved.
Should we submit 5-mn Meter Data?
First Choice: Submit 5-mn meter data (Revenue-Quality Data) Most accurate settlement
– Resources with loadings that fluctuate a lot in RT market, such as wind farms, hydro plants, and combined-cycle resources Big advantage to use 5-mn revenue-quality meter data to compute RT payments for generators
– Resources with loadings that do not fluctuate in RT market, such as nuclear or coal units Continue using Hourly Meter Data, not a big need to implement 5-mn meter
Second Choice OK for transition period
– Submit hourly meter data for generators using Revenue-Quality Meters
– RTO will derive 5-mn meter data by profiling using 5-mn state-estimator data
Third choice Not recommended
– Use 5-mn meter data obtained from SCADA or state estimator to perform RT settlement
First Choice: Actual 5-Minute
Meter Data
Second Choice: Actual Hourly
Meter Data profiled against State
Estimator Data
Third Choice: State Estimator 5-
Minute Data

Impacts of 5-mn Settlement on Energy
Accounting and MDMA Functions Review meter data for all resources. Decide whether or
not to upgrade meters to handle 5-mn granularity:
– Generators
– Loads, including Pumping Loads for Pump-Storage plants
– Interties
Modify data interfaces to import 5-mn meter data
Update data-validation rules to detect potential errors in 5-mn meter data
Upgrade ISO-communication software to submit 5-mn meter data for selected resources
Provide selected reports to front-office and plant personnel at 5-mn level -- showing impact of 5-mn meter data on market operations, RTO settlement, and plant P&L

Key Takeaway Points from Webinar
To support 5-mn settlement, market participants will need to submit 5-mn meter data for selected generators. Using 5-mn meter data will yield more accurate settlement results, especially for units that move a lot in RT, such as wind/solar farms, combined-cycle resources, hydro resources, etc…
PCI Energy-Accounting System provides a flexible IT architecture to manage a large volume of meter data for both hourly and 5-mn meter data:
– Set up meters
– Import meter data
– Validate meter data
– Build reports
PCI also provides a multi-dimensional data warehouse to support enterprise data reporting
