SENS enables the transition to a fossil-free energy production

Tre bilder i ett

The rapidly increasing electrification of society means major technical challenges and very large investment needs

SENS develops sustainable energy projects for

  • large energy consumers such as municipalities and industries
  • industrial and financial investors in the energy market

SENS combines knowledge of renewable energy production, energy storage and infrastructure financing to

  • increase supply security, planability and flexibility in the electricity system and
  • optimize capital use when investing in the electricity system

SENS (Sustainable Energy Solutions Sweden Holding AB) offers solutions that enable the transition to a fossil-free and CO2-neutral energy supply both locally and internationally. SENS develops, designs, builds and sells large-scale energy projects by combining next-generation energy storage technologies: underground pumped storage (UPHS) and battery systems (BESS) with energy from solar and wind power.
