Powering the switch

STOR Power is a private limited company established to develop, construct and operate flexible reserve power facilities in the UK to support the transition to a low carbon future.

STOR Power was founded in 2015 after significant success working in the UK solar industry and a realisation by its founder, Jon Antoniou, that demand would increase for reserve power due to the phasing out of old coal, CCGT and nuclear plants, and the intermittent and unreliable nature of renewable energy.

Our mission is to provide power when others are unable to.



The management team has a cumulative 100+ years of experience in the energy and infrastructure sectors.

Jon Antoniou

Jon Antoniou

CEO and Founder

Jon Antoniou is the CEO and Founder of STOR with over 20 years of experience in the construction industry of which 18 years are within the energy sector.

Jon began his first business venture in 2010 as CEO and Founder of Eco NRG Group, a very successful solar developer, installer and O&M provider. In 2015, Jon could see that solar developments were diminishing in the UK due to drastic subsidy reductions. At the same time, there was an increasing demand for reserve power and as a result STOR Power was founded.

Jon’s mission is to enhance and positively influence the UK electricity network via renewable energy and reserve power technologies and to create investment opportunities for other like-minded individuals.
