With lush vegetation and an abundance of tropical flowers, the island of Kauai is one of the eight main Hawaiian islands and a unique natural paradise in the middle of the Pacific. Its isolated location is both a blessing and a challenge – particularly for local energy supplier KUIC. Fossil fuels have to be imported by ship from more than 4,000 km away. This is inefficient, expensive and causes CO2 emissions. So, by 2023, KIUC wants renewable sources to supply half its total energy needs. An innovative solar power station now stores energy from sunlight in a Tesla battery farm, so that clean electricity is available at night, too. At the same time, KIUC no longer wants to risk polluting the environment by using oil or gas-filled connection components. PFISTERER was the only supplier able to meet this requirement.
