Equivalent forced outage rate calculation

Equivalent Forced Outage Rate Calculation: EFOR = FOH + EFDH . (FOH + SH + Syn Hrs. + Pmp Hrs. + EFDHRS) where EFDH = (EFDHSH + EFDHRS) EFDHSH is Equivalent Forced Derated Hours during Service Hours. EFDHRS is Equivalent Forced Derated Hours during Reserve Shutdown Hours.

Equivalent hours are derate events expressed as full outage hours. Equivalent hours are calculated by multiplying the derate duration by the MW reduction and dividing by NMC.

What is forced outage rate?

Forced Outage Rate means the hours a generating unit, transmission line, or other facility is removed from service, divided by the sum of the hours it is removed from service plus the total number of hours the facility was connected to the electricity system expressed as a percent.2

How to calculate derating during RS and planned outage?

Planned Outage = POH x NMC Seasonal Derate = ESEDH x NMC In Service Unit Derating = (EFDH-EFDHRS) x NMC + (EMDH-EMDHRS) x NMC + (EPDH-EPDHRS) x NMC Derating During RS =

How do you calculate in-service load reduction?

In Service Discretionary Load Reduction = Average Spinning Reserve x SH Reserve Shutdown = RSH x Resource Unavailable Turbine Hours (Hydro) = RUTH H x NMC Service Hours Non Generating (Synchronous) = Sync Hours x NMC Forced Outage = FOH x NMC Seasonal Derate = ESEDH x NMC In Service Unit Derating =

What is the formula for calculating in service actual generation?

In Service Actual Generation = Average Load x SH In Service Discretionary Load Reduction = Average Spinning Reserve x SH Reserve Shutdown = RSH x Forced Outage = FOH x NMC Maintenance Outage = MOH x NMC

What is a forced outage rate?

Forced outage rate means the hours a generating unit, transmission line, or other facility is removed from service, divided by the sum of the hours it is removed from service plus the total number of hours the facility was connected to the electricity system expressed as a percent.2.

What is average rate?

Average Rate means the simple arithmetic mean of the Bank Rates in effect at 4:00 p.m. Eastern Time each day during the calendar month immediately before the calendar month in which payment is made;

What is Eford in electricity?

Equivalent Demand Forced Outage Rate (EFORd) is a measure of the probability that a generating unit will not be available due to forced outages or forced deratings when there is a demand on the unit to generate.

What is an excess rate on an ARD loan?

Excess Rate With respect to each ARD Loan, the excess of (i) the applicable Revised Rate over (ii) the applicable Mortgage Rate, each as set forth in the Mortgage Loan Schedule.

What is weighted average net mortgage rate?

Weighted Average Adjusted Net Mortgage Rate As to any Distribution Date, the average of the Adjusted Net Mortgage Rates on the Mortgage Loans, weighted on the basis of the Stated Principal Balance of each Mortgage Loan as of the Due Date in the prior calendar month (after giving effect to Principal Prepayments received in the Prepayment Period related to that prior Due Date).

What is adjusted net maximum mortgage rate?

Adjusted Net Maximum Mortgage Rate With respect to any Mortgage Loan (or the related REO Property), as of any date of determination, a per annum rate of interest equal to the applicable Maximum Mortgage Rate for such Mortgage Loan (or the Mortgage Rate in the case of any Fixed-Rate Mortgage Loan) as of the first day of the month preceding the month in which the related Distribution Date occurs minus the sum of (i) the Trustee Fee Rate and (ii) the Servicing Fee Rate.

What is blended rate?

Blended Rate means, with respect to any Taxable Year, the sum of the effective rates of tax imposed on the aggregate net income of the Corporate Taxpayer in each state or local jurisdiction in which the Corporate Taxpayer files Tax Returns for such Taxable Year, with the maximum effective rate in any state or local jurisdiction being equal to the product of: (i) the apportionment factor on the income or franchise Tax Return filed by the Corporate Taxpayer in such jurisdiction for such Taxable Year, and (ii) the maximum applicable corporate tax rate in effect in such jurisdiction in such Taxable Year. As an illustration of the calculation of Blended Rate for a Taxable Year, if the Corporate Taxpayer solely files Tax Returns in State 1 and State 2 in a Taxable Year, the maximum applicable corporate tax rates in effect in such states in such Taxable Year are 6% and 5%, respectively and the apportionment factors for such states in such Taxable Year are 60% and 40%, respectively, then the Blended Rate for such Taxable Year is equal to 5.6% (i.e., 6% times 60% plus 5% times 40%).

What is forced outage in electrical engineering?

In electrical engineering, forced outage is the shutdown condition of a power station, transmission line or distribution line when the generating unit is unavailable to produce power due to unexpected breakdown.

How can the risk of a force outage be minimized?

The risk occurred from force outage can be minimized by having it insured.

What does “for” mean in power station?

Forced outage rate (FOR or FOAR) of a power station unit is the probabil ity that the unit will not be available for service when required .

An important statistic calculated from the raw GADS data is the Equivalent Forced Outage Rate (EFOR), which is the hours of unit failure (unplanned outage hours and equivalent unplanned derated hours) given as a percentage of the total hours of the availability of that unit (unplanned outage, unplanned derated, and service hours).

The Generating Availability Data System ( GADS) is a database produced by the North American Electric Reliability Corporation (NERC). It includes annual summary reports comprising the statistics for power stations in the United States and Canada.

When was the NERC GADS system created?

This reporting system, initiated by the electric utility industry in 1982, expands and extends the data collection procedures begun by the industry in 1963. NERC GADS is recognized today as a valuable source of reliability, availability, and maintainability (RAM) information.

When did utilities start using GADS?

Utilities started their reporting using the GADS guidelines on January 1, 1982. GADS superseded the earlier data collection procedures begun by the Edison Electric Institute (EEI), a program started in the mid-1960s. GADS contains many of the same elements previously collected by EEI in addition to the many new data items.

Is GADS the same as EEI?

GADS contains many of the same elements previously collected by EEI in addition to the many new data items. This seeming duplication of data was done intentionally: the EEI information can be derived from GADS so analyses that include data from earlier than 1982 can be completed.
