   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).

   Toronto during the Northeast blackout of 2003, which required black-starting of generating stations.. A black start is the process of restoring an electric power station, a part of an electric grid or an industrial plant, to operation without relying on the external electric power transmission network to recover from a total or partial shutdown.

4. Availability factor - Wikipedia

   en.wikipedia.org/wiki/Availability_factor

   With this definition, modern wind turbines which require very little maintenance, have very high availability factors, up to about 98%. Photovoltaic power stations which have few or no moving parts and which can undergo planned inspections and maintenance during night have an availability factor approaching or equal to 100% when the sun is shining.

5. Forced outage - Wikipedia

   en.wikipedia.org/wiki/Forced_outage

   Forced outage rate (FOR or FOAR) of a power station unit is the probability that the unit will not be available for service when required.. FOR is defined as the number of hours the unit is on forced outage over the total number of hours in a year (which is the sum of hours the power station is available for service and hours the power station is in forced outage).

6. Power purchase agreement - Wikipedia

   en.wikipedia.org/wiki/Power_purchase_agreement

   A power purchase agreement (PPA), or electricity power agreement, is a long-term contract between an electricity generator and a customer, usually a utility, government or company. [1] [2] PPAs may last anywhere between 5 and 20 years, during which time the power purchaser buys energy at a pre-negotiated price.

7. Diesel generator - Wikipedia

   en.wikipedia.org/wiki/Diesel_generator

   A specific model of a generator operated as a standby generator may only need to operate for a few hours per year, but the same model operated as a prime power generator must operate continuously. When running, the standby generator may be operated with a specified - e.g. 10% overload that can be tolerated for the expected short running time.
