Swissgrid is pursuing a long-term infrastructure programme called Strategic Grid 2040, which includes 31 major grid projects up to 2040 and foresees investments of around CHF 5.5 billion. This programme involves reinforcing approximately 400 kilometres of existing lines, constructing around 790 kilometres of new lines and dismantling about 790 kilometres of old lines (source: swissgrid.ch). A standout project is the 220 kV Gotthard cable, which replaces a roughly 23-kilometre overhead line over the Gotthard Pass with an underground cable in the Gotthard road tunnel. This project is realised in cooperation with the Federal Roads Office and has an estimated investment of over CHF 140 million (source: swissgrid.ch). The Bickigen–Mettlen project replaces an ageing 220 kV line between Bern and Lucerne with a new line, with construction planned between 2031 and 2034 (source: swissgrid.ch). Additionally, a new transformer was commissioned in 2025 at the Bonaduz substation in Graubünden to strengthen the transmission grid in this region (source: swissgrid.ch). Swissgrid operates around 6,700 kilometres of lines and about 147 substations, including 41 international interconnectors, highlighting the importance of international coordination for European electricity flows (source: swissgrid.ch).

In 2024, Swissgrid achieved net revenue of CHF 1.825 billion, an increase of CHF 605.9 million compared to 2023. This rise reflects the tariff-based and pass-through nature of the revenues, not growth in competitive business (source: report.swissgrid.ch). In April 2025, Swissgrid published the Strategic Grid 2040 programme, defining long-term infrastructure needs and naming 31 projects with an investment volume of around CHF 5.5 billion (source: swissgrid.ch). In March 2025, the Gotthard cable project received building approval, a key milestone for constructing the 220 kV tunnel cable system (source: swissgrid.ch). Also in March 2025, Swissgrid submitted the application for the sectoral planning procedure for the long-term renewal of the Bickigen–Mettlen line (source: swissgrid.ch). Innovation work has been expanded, including the PV4Balancing pilot project, which investigates how photovoltaic systems can provide flexibility for the balancing energy market (source: swissgrid.ch). In 2025, Swissgrid invested CHF 356.6 million, of which CHF 281.2 million was in grid expansion and CHF 15.3 million in maintenance, with a net profit of CHF 91.7 million (source: swissgrid.ch).

Swissgrid offers a wide range of roles in electrical engineering, grid operation, grid planning, civil engineering, project management, asset management, maintenance, procurement, legal, regulation, finance, communications, human resources, IT, cybersecurity, data analysis and electricity market operations. Technical roles especially include grid control, protection and automation, high voltage technology, grid studies, balancing energy, energy economics and cross-border coordination (source: swissgrid.ch). Operational and technical activities are spread across locations in Aarau, Prilly, Castione and Ostermundigen, with some positions requiring regular travel to substations and construction sites throughout Switzerland (source: swissgrid.ch). The working environment is characterised by a public infrastructure mandate emphasising safety, reliability, regulatory compliance and long-term planning. Grid control roles may involve shift and on-call duties (source: swissgrid.ch). Swissgrid recruits across all language regions of Switzerland and operates in a multilingual, internationally connected environment, with German, French, Italian and English relevant depending on location and role (source: swissgrid.ch). The company offers professional development, flexible working models, pension and insurance benefits, as well as modern work infrastructure, with specific benefits varying by position (source: swissgrid.ch).
