Otta's take

Xav Kearney

CTO of Otta

In 2020, renewable energy was the only energy source for which demand increased and it is expected that renewables will account for 90% of capacity increases over the next two years. Arenko Group aims to modernise the infrastructure that ensures this capacity can be optimised.

The company provides software solutions that allow energy operators to supply energy more efficiently to the grid. Through their AI-powered software system, Arenko supports battery asset owners and operators to optimise their energy storage by allowing them automatically buy and sell electricity on the grid ensuring they maximise revenue across multiple power and energy markets at the same time.

Arenko currently works with the battery and grid operators across the UK and are part of the National Grid ESO’s Technology Advisory Council, along with the likes of Transport for London and Octopus Energy. With a focus on creating a faster path to net-zero and a more resilient energy grid, Arenko aims to become a global leader in this space.

  • Making sure that everyone feels valued and is able to perform to the best of their ability is critical to our success. That is why diversity and inclusion is increasingly on the agenda here at Arenko. Some of our top initiatives include:
  • Partnering with Future CodeHers to teach girls at school about careers and opportunities in technology and software development
  • Working with the Royal Academy of Engineering on their annual Diversity and Inclusion engineering survey
  • Adapting our recruitment practices to ensure it is a more diverse and inclusive process. Our hiring process and job postings have been designed to reduce biases and encourage a variety of people to apply
  • We have multiple Mental Health First Aiders and provide employees with the opportunity to have this training. We provide mental health support via mental health days, Wellbeing Wednesdays, our Employee Assistance Program and other wellness initiatives to support team members
  • In September 2021, we were pleased to achieve a gender split of 40% female and 60% male. We know we still have a way to go, but we are continuously making improvements to ensure we are diverse as possible with people from all backgrounds
  • We also realise that we can always improve and ask the team if they have any ideas or suggestions to improve out cultures. We'd love to hear about any ideas you have!
