To save the planet by enabling a zero carbon grid world wide.
14% employee growth in 12 months
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 increase their grids' flexibility and secure their energy supply more efficiently. Through its AI-powered software system, Arenko optimises energy storage for battery asset owners and operators, so they can automatically buy and sell electricity on the grid, maximising revenue across multiple power and energy markets simultaneously.
Arenko currently works with the battery and grid operators across the UK and is part of the National Grid ESO’s Technology Advisory Council, with the likes of Transport for London and Octopus Energy. With a focus on accelerating the path to net zero and a more resilient energy grid, Arenko aims to become a global leader in this space.
