Our key tasks

We are primarily tasked with providing power transmission services, system services and facilitating the energy market. Our core tasks follow from our appointment as grid operator under the Dutch 'Elektriciteitswet' (E-wet) and the German 'Energiewirtschaftsgesetz' (EnWG).

Electricity market

The energy sector is developing rapidly. The process of European market integration began some years ago. Its purpose is to create a single European market that enables market parties to trade gas and electricity across national borders easily and efficiently.

Life-Saving Rules

TenneT applies six Life-Saving Rules. These rules are intended to prevent fatal accidents, and are based on the safety standards applicable in the petrochemical industry and a careful analysis of past high-risk incidents at TenneT. TenneT employees or personnel working for our (sub)contractors should never feel pressured to risk their lives for the sake of the company. The six Life-Saving Rules empower employees to say 'No' and stop the work in any situation where a Rule applies.


The TenneT organization has grown quickly in the past few years: the number and scope of our projects, the size of our workforce, and the number of (sub)contractors that we work with have all increased significantly. These developments have also resulted in an increased risk of accidents. Unfortunately, TenneT had to cope with fatal incidents. a fatality a few years ago and also recently. We have to do everything we can to prevent this from happening again.

Six Life-Saving Rules

  • Prevent dropped tools and equipment
  • Comply with electrical safety rules
  • Work with a valid work permit when required
  • Protect yourself against falling when working at height
  • Do not work, walk or stand under a suspended load
  • Use personal protection equipment when required

Life-Saving Rules and FAIR approach

The Life-Saving Rules (LSR) system has proven its value in practice all over the world by preventing fatal incidents, particularly in the petrochemical industry. The rules are derived from international standards adopted by oil- and gas-producing companies (OGPs). The TenneT LSRs are also based on analyses of high-risk incidents (HRIs) that have occurred at TenneT in the past few years. It is important to realize that these are not new rules. Rather, the LSRs are a set of six existing rules that have now been given special status because they are essential in preventing fatal accidents.

The so-called 'FAIR approach' (Flowchart Analysis of Investigation Results) has been developed to make sure we all comply with the rules. When an LSR is violated, the FAIR approach is used to determine which measures need to be implemented. The FAIR approach is not aimed at punishing undesirable behaviour, but at gaining insight into the reasons for the behaviour and the context in which it occurred. This will enable TenneT to learn from incidents and further improve our safety performance.
