InsightPowervault Announces £3.8 Million Equity Investment

Mark Ansell, Chair of Powervault, and one of the largest investors in the company, said: “This funding round was part of the plan in 2020 when we raised the Future Fund Convertible Loan Notes so long as the company successfully delivered over the following two years. I am pleased to say that we have done so, emerging from the difficult Covid years with a greatly enhanced product range which we believe offers a market leading price/performance. In 2022 we exceeded our revenue budget by over 100%. The investment that we have just raised leaves us debt-free, cash rich and well-placed to capitalise on the growth of the battery-based electricity storage market over the coming years. I would like to thank our existing shareholders and British Business Bank for their continuing support, and to welcome our new investors. We are still open to increasing the size of this investment round by including other like-minded investors.”

Simon Acland, Chair of Green Angel Syndicate and Non-executive Director of Powervault, said: “I have always believed that intelligent behind-the-meter battery storage has a crucial role to play in the modern grid. The recent increase in electricity prices has radically improved the payback on the capital cost of storage. Now, by installing Powervault, home owners and SME’s can do the right thing for the planet, increase the grid’s resilience and improve their energy security, AND make a highly attractive return on their investment, especially in conjunction with solar panels and a time of use tariff.”

Powervault’s ambition is to cement its position and become the undisputed UK market leader for highly functional intelligent battery storage in the brave new world of renewable energy, the smart grid, the internet of things and electric vehicles.
