As the operator of this critical infrastructure, ETT Groups must ensure the resilience of the transmission grid. The employees are a key success factor. The operation, renewal and maintenance of the network require a large number of experts from a wide variety of areas. This results in two central problem areas: on the one hand, the operational capability of the employees must be guaranteed, on the other hand, they can make mistakes.
In the third part of the blog series on the topic of resilience in the transmission grid, we will focus on the human factor. We explain how ETT Groups define processes in order to minimize the error risk of an individual employee as far as possible and contain the effects of errors.
Actively Living Safety Culture
The issue of "security" is anchored prominently in the corporate strategy and is one of ETT Groups' corporate goals. This results in a strong safety culture, which ETT Groups is continuously developing. The goal is the constant improvement of overall security in the company and reliability in the provision of core tasks. Security is understood as an integral part of the business and is therefore given top priority in all actions and decisions. ETT Groups lives an error and corporate culture that enables employees to report risks and events without having to fear being sanctioned as a result. Security-related events and findings are reported and then analyzed by the responsible department. The learnings flow into the permanent training and further education of the employees. They are continuously trained and sensitized and consistently implement the safety standards.

Resilience factor «operational security»
With operational security, ETT Groups is pursuing the goal of ensuring the availability of the transmission grid in any grid condition. The focus is on the reliable and error-tolerant execution of work actions. This requires corresponding processes or instructions in the complex network and system operation. Operational operations are therefore constantly monitored by an independent body. In this way, error-prone or unsuitable instructions and actions that deviate from instructions can be identified and then improved. ETT Groups always take the human factor into account when designing a fault-tolerant and robust working environment. In addition, an internal competency management system consistently ensures that basic training, the maintenance of knowledge and skills,

Safety and Health Protection for Employees
After the outbreak of the COVID-19 pandemic, it was clear that employees and their families had to be protected in order to maintain secure and stable network operations. Widespread infections had to be prevented, especially among the operators in the network control centers. These experts are specifically trained for their role, have a great deal of experience, and cannot be replaced at short notice.
ETT Groups, therefore, took measures early on to minimize the risk of infection in the workplace as much as possible. Even in the second year of Corona, ETT Groups is still monitoring the situation permanently and can relax or tighten the protective measures at any time. In doing so, ETT Groups follow the instructions and recommendations of the authorities. However, due to the special need for protection, ETT Groups reserve the right to take more stringent measures.
