What is a LOLP?

What is a LOLP?

The index “LOLP” refers to a probability of outages, where the “LOLE” index describing an expected value. The LOLE index analysis forms the basis of calculating how many particular generators, or group of generators contribute towards planning reserve.

How do you calculate loss of load expectation?

In short, the calculation consists of the following steps.

  1. Determine the total electricity demand profile.
  2. Determine the total electricity (volatile) production profile.
  3. Subtract total electricity demand profile from the total electricity production profile resulting in a residual demand profile.

What is the full form of LOLP?


Acronym Definition
LOLP Loss-Of-Load-Probability

What is Loss of load probability?

Loss of load probability (LLP) indicates how often a system is not being able to satisfy the load demand or the mean load percentage not met by the system.

How is Lole calculated?

An alternative metric is the Loss of Load Expectation (LOLE), which is the number of days of outage or the number of times in a given period that the load will be greater than the demand. This can be expressed as LOLE = LOLP * N/24.

What is the meaning of loss of load?

A Loss of Load Probability (LOLP) is a measure of the probability that a system demand will exceed capacity during a given period; often expressed as the estimated number of days over a long period, frequently 10 years or the life of the system. (

What is expected energy not served?

expected energy not served . (EENS) means, in a given zone and during a given time period, the energy which is expected not to be supplied due to insufficient resources to meet demand needs.

What is load formula?

According to Sir Isaac Newton, the force of an entity equals its mass, multiplied by acceleration. This basic principle is what is used to calculate load force, which is the force that opposes that entity. Apply Sir Isaac Newton’s formula: force = mass x acceleration.

What is the maximum demand calculation?

Maximum demand Calculation: Maximum Demand= Connected Load x Load Factor / Power Factor.
