Octopus Energy Group

Octopus Energy Group helps customers keep a tight grip on their purse strings while cutting down their carbon footprint. Its proprietary energy-tech platform, Kraken, makes it easier for users to customize their energy sources and pricing structures. Retail and business customers can opt to power their properties from 100% renewable energy sources; Octopus also installs solar panels and heat pumps. The company also offers various smart-grid programs that allow customers to buy electricity at reduced rates for use during off-peak hours—a good deal for anyone charging an electric vehicle overnight. Kraken now has 30 million customer accounts in 16 countries, including about 13 million in the U.K.
