Renewable energies
SEAR offers holistic solutions for decentralized energy generation and energy storage to meet the challenges of the energy supply of the future.
SEAR GmbH draws on its many years of expertise in the construction of power plants. This enables us to act in a target-oriented manner in the interests of our customers. Together with other small and medium-sized companies and distribution grid operators, we are working on efficient solutions for transfer technologies such as power-to-heat and energy storage. In the future, we see ourselves as a system integrator for the construction of smart grids and combined cycle power plants.
