Energy Sector Digital Transformation

How we helped DTEK facilitate the digital transformation of the Energy sector in Ukraine


DTEK is a Ukrainian energy distribution system operator working to advance the health and prosperity of Ukrainian society. DTEK’s objective was to simplify electric bills management and payment systems.

Artkai helped DTEK execute an agile, digitally informed, and design-focused solution. DTEK now provides its customers with better access to detailed information, and DTEK helps its customers gain control of their energy consumption to reduce costs.
