The initiative aims to raise €100 million (US$115 million) to fund rooftop solar and Battery Storage Systems (BSS) for Ukrainian businesses and public sector institutions. Over the next three years, it will finance 100 energy projects.

Since the outbreak of the Russia-Ukraine war, critical energy infrastructure has suffered extensive damage or destruction, severely disrupting power supplies for civilians. The RISE programme will enhance grid stability, reduce electricity costs for consumers, and protect communities from the impacts of blackouts and rising energy prices.

"They (DTEK) are rebuilding at pace and pioneering a decentralized, smart energy system powered by homegrown renewables," said Greg Jackson, Octopus Energy Group founder and CEO.

DTEK previously announced plans to build one of Europe's largest energy storage facilities with six installations across the country, totaling 200 megawatts to power 600,000 households.   

According to DTEK, Ukraine's commercial and industrial energy market has an untapped potential of 300 megawatts annually, valued at 200 million euros ($229 million).
