Safety at TenneT

TenneT attaches great importance to safety. Every day, as an organisation, we are aware of the risks associated with our activities. TenneT wants every employee to come home safely, every day.

Our safety ambitions

In recent years TenneT has shown an enormous improvement in safety behaviour, including certification on step 3 of the Safety Culture ladder (SCL). However, safety requires constant attention and focus. And that is why we need to take further steps. Our safety performance reflects the quality of our business operations. Operational excellence can only be achieved through a broad, proactive, risk-based approach to our business activities and processes. We want to be recognised as an excellent safety performer.

TenneT OHS Policy

On 31 August 2020 the Executive Board signed the new TenneT OHS policy. The OHS policy explains and gives direction to TenneT's employees and other stakeholders about the way in which TenneT carries out its activities and what we expect from employees in order to achieve our safety ambition of Zero Harm. Besides a strong focus on the "human" aspects of OHS, such as psychological safety, learning organisation and safety culture, attention is also paid to the "organisational" elements of OHS, such as risk management, safe operations throughout the chain and contractor management. Working safely is the responsibility of every employee.

Safety Vision 2019 - 2022

Act safe, stay safe! That is TenneT's new slogan when it comes to our long-term vision on safety.
We have translated our ambition into the Safety Vision 2019-2022.  This focuses on two closely linked pillars:

  • Safety Leadership
  • Safety Execution

To strengthen these pillars, we will also work on a strong foundation. In particular, the further development of Safety Leadership and our Safety Culture and the further improvement of the safe behaviour of our contractors must also lead us to SCL certification on step 4.


The Roadmap follows from our Safety Vision. On the basis of this, we show which activities we will undertake over the next four years in order to achieve our goals.

Safety Leadership

Our safety performance must reflect our operational excellence. TenneT wants to be regarded as a safety leader, and we believe that all TenneT employees should assume the role of leaders by working safely themselves. We therefore invest in training programmes for our managers and employees.

Contractor Management

Contractor management is a key element of our Safety Vision 2018. We want everyone working for TenneT to return home safely at the end of each day. TenneT wants to contract top safety performers to contribute to our projects. We are looking for contractors who take safety just as seriously as we do, and who apply the highest safety standards when performing their work.

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.
