Our take
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 their AI-powered software system, Arenko supports battery asset owners and operators to optimise their energy storage by allowing them to 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.
