Flexible AC transmission systems (FACTS): Enhance grid stability, boost power quality, and increase network capacity using advanced power electronics.
Battery energy storage solutions (BESS): Provide grid balancing, frequency control, and energy dispatch to augment renewable integration.
Substation solutions and equipment: Complete modular systems including transformers, switchgear, protection relays, and automation components ensuring safe, reliable power distribution.
SF6-free high-voltage switchgear: Environmentally friendly solutions reducing greenhouse gas emissions while maintaining high performance.
Digital solutions and services: End-to-end digitalization enabling grid monitoring, diagnostics, predictive maintenance, and autonomous operations to improve efficiency and reduce downtime.

The energy transition requires large-scale changes to the infrastructure of our power grids. At Siemens Energy, we connect energy systems and bring power from where it’s generated to where it’s needed. With solutions such as our HVDC PLUS® technology, based on modular multi-level converters, for instance, Siemens Energy creates grid connections to offshore wind farms, integrates renewables, and secures a safe and efficient energy supply for industries, such as data centers.

An increasing system complexity demands for investments into grid infrastructure that stabilize the grid and ensure uninterrupted energy supply. With our flexible AC transmission systems (FACTS), such as our synchronous condensers, STATCOM or E-STATCOM solutions, we ensure stable and efficient grid operations. Our advanced transformers and battery energy storage solutions enable grid operators to be agile and adaptive in the wake of increasing power fluctuations. And our wide range of power transmission service offerings enables a reliable and available grid – anywhere, anytime.

The grid of the future needs digital solutions to make today’s utilization more efficient, more flexible and to address evolving complexities. At Siemens Energy, we drive the transformation of power grids towards an autonomous digital future through end-to-end digital solutions, for example with our grid enhancing technologies, engineered to enhance performance by turning data into actionable insights.

Reducing carbon emissions is our ultimate goal at Siemens Energy – and this is reflected throughout our offerings and operations. With our Blue portfolio, we use clean air and vacuum switching technology instead of F-gases, delivering Zero F-gases, Zero toxicity and Zero harm to human health and the environment. Micro substations offer a sustainable alternative for existing transmission grids with virtually unlimited power availability, high-quality service, and suitability for rural areas. We also decarbonize our supply chains by partnering to reduce material emissions, for example by using alternative insulation liquids, or recycled coppper in transformers.

In view of major global, but regionally distinct developments like demand growth, decentralization, decarbonization and digitalization, a reliable access to energy has to be secured. Siemens Energy shares this priority with all power utilities, and specifically with transmission and distribution system operators. As one of the leading partners in this area, Siemens Energy's global, highly skilled teams work hard to reach these common goals.

Respecting the high safety and reliability standards, Siemens Energy helps oil and gas customers to ensure an efficient energy supply for upstream, midstream and downstream applications – no matter if on- or offshore.
