Performance benchmark

We look critically at our own performance and we benchmark it against that of other companies, both in and outside the energy sector. We do so mainly to learn and identify promising opportunities. Some benchmark data are explained below.

Benchmark within the energy sector

Outage duration

Our networks are highly reliable. The electricity outage duration at Liander averaged 23.3 minutes in 2016, higher than the national average of 21 minutes in 2016. The gas outage duration for customers in the Liander service area averaged 85 seconds in 2016, also lower than the national average in 2015 (129 seconds).

International benchmark for outage duration

National benchmark


Absenteeism at Alliander came to 4.1% in 2016 (2015:3.8%), compared with a national average of 3.8% in 2016.


Alliander also takes part in the annual Transparency Benchmark, which the Ministry of Economic Affairs conducts among 500 companies. This benchmark indicates how transparent companies are in their reporting. In 2016, Alliander ended in 1st place (2015: 9th) and was the highest-placed company in the energy sector.

Great Place to Work

Alliander has the ambition to be a top-class employer for its current and future employees, so that their expertise is retained on a permanent basis. Only an objective assessment can really tell us whether Alliander is a top-class employer. This is why we take part in Great Place to Work – an employer survey in which tens of Dutch companies participate every year. Based on last year’s measurement, Alliander failed to earn a place on the Best Workplaces list.
