Dec 2023Undisclosed stageCPP Investments; Tokyo Gas; Origin Energy; Generation Investment Management$796M$7.8BOctopus Energy Group, a clean energy technology company and the UK's largest power retailer serving 7.2 million global retail customers, secured additional investment on December 18, 2023, co-led by CPP Investments committing £300m (C$511m), with participation from Generation Investment Management, Origin Energy, and Tokyo Gas. The funding round, totaling around $800m including £625m from existing shareholders, valued the company at $7.8bn (£6.2bn), a 60% increase from the prior December 2021 round. This capital supports global expansion via its Kraken technology platform, which manages 52 million accounts worldwide and is licensed to major energy players, alongside growth in renewables, heat pumps, and EV offerings. CPP Investments highlighted Octopus's role in the energy transition, noting its market-leading customer proposition and technology. The investment aims to create 3,000 green jobs in the UK and fuel international growth. A subsequent May 2024 follow-on by CPP and Generation increased valuation to $9bn (15% uplift), with CPP at 12% and Generation at 13% ownership.
Jul 2022Undisclosed stageCPP Investments (lead); Tokyo Gas; Origin Energy; Generation Investment Management$550M$5BOctopus Energy Group, a global clean energy technology pioneer, completed a funding round on July 26, 2022, securing US$325m from existing investors including Generation Investment Management, Origin Energy, and Tokyo Gas, plus an additional US$225m commitment from CPP Investments, totaling US$550m. This followed a December 2021 primary round where the company was valued at approximately US$5 billion after investments of $600m from Generation Investment Management and $300m from CPP Investments for a 6% stake. CPP Investments led the latest commitments as part of a strategic partnership to support Octopus' global expansion, Kraken technology platform deployment, and integration of renewables into the power system using Kraken Flex. The funds were allocated to bolster Octopus' UK tech operations and international growth, with CPP's portion specifically enhancing renewables integration and smart energy solutions across the supply chain. Octopus, known for its market-leading customer proposition, operates as the UK's largest power retailer and licenses Kraken to support retail, generation, flexibility, and other sectors globally. The company focuses on renewable energy, heat pumps, electric vehicles, and serves customers while managing significant renewable projects. This round built on prior investments from sustainability-focused backers like Generation and CPP, positioning Octopus to accelerate its role in the energy transition.
Dec 2021Undisclosed stageCPP Investments (lead)$300M$5BOctopus Energy Group, a global clean energy technology pioneer, develops the Kraken platform to support retail energy supply, smart grids, and renewables integration. In December 2021, it announced a strategic partnership with CPP Investments, which made an initial US$300 million equity investment to fuel global expansion, Kraken technology deployment, and additions to its Octopus Energy Fan Club wind turbines. This followed a September 2021 round with Generation Investment Management that valued the company at $4.6 billion after a $600 million investment, bringing the post-money valuation to approximately $5 billion in the CPP-led round. The investment supports Octopus's mission to drive the global green energy revolution, enabling faster international growth and technology advancements across the energy supply chain. Kraken, already licensed to major utilities like EDF Energy, Good Energy, E.ON, and Origin Energy, manages over 20 million customer accounts worldwide at the time. CPP Investments, managing Canada Pension Plan assets, committed to potentially increasing capital over time, highlighting Octopus's role in decarbonized energy systems and renewables. This marked Octopus's third major funding round, with subsequent follow-ons including a July 2022 $550 million raise ($325M from existing shareholders plus $225M from CPP) on similar terms to support UK tech, global businesses, and renewables integration. Later investments, like CPP's additional £300M in 2023, continued backing expansion into markets like the US with Kraken deployments.
Sep 2021Undisclosed stageGeneration Investment Management (lead)$655M$4.6BOctopus Energy Group, a UK-based entech company encompassing energy technology, renewable generation, and energy retail across 12 countries, announced a strategic partnership with Generation Investment Management on 27 September 2021. The deal involved up to $600 million investment from Generation, taking approximately 13% equity stake, plus $55 million from Origin Energy, valuing the company at $4 billion pre-deal and up to $4.6 billion post-deal. The immediate investment was $300 million, with another $300 million conditional by June 2022. The funds aimed to accelerate global expansion, enhance the Kraken smart grid platform, and support ambitions to manage 100 million energy accounts by 2027. At the time, Octopus had around 2.5-3.1 million customers, including after acquiring Avro Energy's 600,000 accounts. The company operates retail brands like Octopus Energy, M&S Energy, and others, alongside Octopus Energy Generation managing renewable assets. Generation Investment Management, a $36 billion fund co-founded by Al Gore focused on sustainable businesses, backed Octopus to drive the green energy revolution. This marked a major milestone, building on prior rounds that had already made Octopus a unicorn multiple times. Subsequent rounds in late 2021 and 2022 adjusted valuations higher, but this 2021 deal established the $4.6 billion post-money figure for the specified investment.
Dec 2020Strategic investmentTokyo Gas (lead); Origin Energy$247M$2.1BOctopus Energy Group, a UK-based clean energy technology company, develops the Kraken platform for energy retail and smart grid management, serving 1.8 million UK households at the time and expanding internationally. On December 23, 2020, it announced a landmark partnership with Tokyo Gas, including a joint venture TG Octopus Energy (70% Tokyo Gas, 30% Octopus) to launch Octopus-branded renewable energy services in Japan, marking its Asian entry. Tokyo Gas acquired a 9.7% equity stake for $200 million, with Origin Energy adding approximately $50 million, bringing total new investment to $250 million and valuing the group at $2.1 billion. The investment supported accelerated global expansion, technology development like smart grid enhancements, and the green energy transition, following Octopus's growth amid COVID while maintaining service levels. It positioned Octopus among major players like the UK's 'New Big 6' energy suppliers, with launches in the US, Australia, Germany, and New Zealand, aiming for 100 million global customers by 2027. Origin Energy, having invested earlier in May 2020, used this to maintain its approximately 20% stake. This round built on prior funding, with Tokyo Gas as lead, focusing on renewables and tech innovation. Subsequent rounds, like $655M in 2021 and $800M in 2023 valuing at nearly $8 billion, reflect ongoing growth with the same investors.
May 2020Strategic investmentOrigin Energy (lead)$327M$1.3BOctopus Energy Group, a UK-based energy technology company, announced a major strategic partnership with Australia's Origin Energy on April 30, 2020, where Origin acquired a 20% stake valuing the company at well over £1 billion, achieving unicorn status. The deal included licensing Octopus's Kraken technology platform to transform Origin's Australian retail business and a three-year company guarantee for working capital support in Octopus's UK and international operations. Contracted software licensing revenue exceeded £300 million over the next three years, with the investment earmarked for global expansion, technology development, and establishing a Future Energy Research Centre. Octopus Energy operated an efficient energy retail arm in the UK and Germany at the time. The company remained majority owned by Octopus Group, a £9 billion UK investor in energy, technology, and growth businesses, which is the UK's largest solar energy investor. This investment followed a technology deal with E.On, migrating 6 million UK customers to the Kraken platform. Origin's initial investment exceeded £200 million per company accounts, with the stake acquisition effective May 1, 2020. Subsequent investments by Origin and others have increased over time, but the 2020 round specifically marked Octopus's unicorn valuation and strategic entry into Australia via technology licensing. No specific revenue, ARR, or EBITDA figures for Octopus Energy Group around the round date were detailed in sources.
