Certifications

To ensure consistent improvement, we have already introduced a variety of quality assurance systems and are currently preparing to certify some other systems.

All systems share an obligation to set targets and an annual check of continued improvement, carried out by independent certifiers. Processes are agreed and responsibilities set out in all systems.

When selecting our targets, the focus is on our customer-orientation, taking occupational safety into account when carrying out our activities and, naturally, adherence to statutory and official requirements.

We represent safe and reliable electricity provision, ensuring that our customers can rely on us and that all their needs are met to the best possible standard where electricity is concerned.

Quality management system (DIN EN ISO 9001:2008)

We have developed strategies and concepts for the safe operation of the grid and have plans for maintenance, renewal and development of the technological operating mechanisms in the distribution grid, taking high-performance risk management into account. Metering, measuring and providing consumption figures to our customers to calculate grid usage is as much a part of quality assurance as the high-performing service providers that we have commissioned.
Stromnetz Berlin GmbH's quality management system has been certified under DIN EN ISO 9001:2008 since 2013.

Satisfied users

It is very important to us to show our customers that meeting their expectation of a secure energy supply is a priority for us. Our business processes and quality management system are oriented towards this.

We provide energy for everyday life

Our distribution grid enables all customers to receive an efficient energy supply and is available to all users to the same degree, regardless of which energy supplier they have chosen. As a grid operator aware of our responsibilities, we adhere to the requirements of the new Energy Industry Act and ensure profitable operations whilst guaranteeing the high quality of supply that customers are used to.

Asset Management System (BSI PAS 55:2008)

Our company owns multiple different operating assets such as sites and buildings, substations, protective and control technology, transformers and cables – collectively described as assets.
The standard provides a balance between the competing goals of operational asset quality and profitability, which benefits all customers who use the grid. The particular challenge and responsibility lie both in the number of assets to be managed and, significantly, in the heavy costs and long-term nature of decisions.

Our asset management system depicts the entire "lifecycle" of the operational asset being used. We design the construction, operation, maintenance and expansion of our assets as effectively and cost-consciously as we do their dismantling at the end of their useful life. After systematic analysis of the load and feed situation, the grid structure is altered to adapt to anticipated future supply demands. The integration of new loads, such as major commercial customers, are taken into account here along with the management and coordination of decentralised generation plants and energy storage plants.

Since 2013, Stromnetz Berlin GmbH's asset management system has been certified according to the BSI PAS 55:2008 standard. Stromnetz Berlin GmbH is the first grid operator in Germany to hold this certificate. BSI PAS 55:2008 is the leading international standard for holistic, sustainable management of physical operational assets.

Occupational safety management system (BS OHSAS 18001:2008)

Stromnetz Berlin GmbH currently employs around 1.300 people. Good working conditions and preventative occupational health and safety are basic prerequisites for good working results and engaged employees.
The Board of Management takes its responsibilities towards its employees very seriously. Support from representatives of the trade association ETEM and an annual check by an independent certifier should ensure that we are using the best possible working methods, in order to continually improve working conditions and reduce or remove problems.

However, awareness of responsibility does not end with Stromnetz Berlin GmbH's employees. The working conditions in third-party companies and/or service providers are looked at by our procurement team in their selection process, to ensure that we can guarantee that third parties we work with adhere to high standards of safety.

Since 2009, Stromnetz Berlin GmbH's occupational safety management system has been certified to the BG ETEM standard, NLF / ILO-OSH:2001, based on the standard BS OHSAS 18001. To simplify the integration of all systems, our occupational health and safety management system is certified according to the BS OHSAS 18001:2007 standard in 2015. When the reworking of the BS OHSAS standard is complete, the new standard will be the ISO 45001.

Information security management system (ISMS) according to ISO/IEC 27001:2013

The key criterion for a distribution system operator is the availability of an electricity grid which is as close to failsafe as possible. This necessitates protecting the information and communication channels needed to operate the distribution network against unauthorised access. In order do this, the information and communications technology (ICT) systems must operate smoothly. Stromnetz Berlin GmbH therefore pays great attention to the security of its ICT systems.

The German government attaches great importance to adequate protection of the ICT systems needed for the secure operation of networks. Article 11 para. 1a of the German Energy Industry Act (EnWG), as amended on 17 July 2015, and the Federal Network Agency's IT security catalogue derived from it, form the statutory framework and set out the measures to be implemented by distribution system operators.

  • Stromnetz Berlin GmbH operates an information security management system (ISMS) in accordance with ISO/IEC 27001:2013 for the area of application, "ICT systems for secure network operation" in order to fulfil
  • the statutory requirements,
  • its own security objectives,
  • the requirements of the population of Berlin with regard to a reliable electricity supply and
  • in order to protect information and information processing systems.

The ISMS restricts the operational effects to information, persons involved and systems within the area of application. The system falls under the responsibility of the executive management and its effectiveness is verified at least once a year. Compatibility with the existing management systems operated by Stromnetz Berlin GmbH and the planned integration of the smart meter gateway are guaranteed.

Security has always been a fundamental criterion for the operation of electricity distribution networks. This is why we intend to submit our certification to the Federal Network Agency before this becomes mandatory on 31 January 2018. In autumn 2016, Stromnetz Berlin GmbH will have the ISMS certified by an independent body suitably accredited to issue such certification.

Environmental protection

Our environmental and energy management systems are certified as well. Conserving the environment and preserving natural habitats are key operational imperatives for us. We aim for sustainable and resource-conserving energy distribution.
