The Project
ESB International was appointed as a consultant to take over management control for KEK in Kosovo. The goal was to transition KEK into a financially sustainable, self-sufficient and market-driven company providing reliable energy services.
KEK was a vertically integrated utility with mining, generation, transmission, distribution and supply activities. The two open-cast lignite mines supply coal to two power stations with a total installed nominal capacity of 1,480 MW.
The Challenge
When ESB International took over management control, KEK owed over €200M in electricity debt, and more than 50% of all connected consumers were illegal.

The Solution
- Data Analytical team plus commercial and revenue protection departments
- Incentive and bonus schemes
- Increase disconnection effectiveness
- Improve customer services through a new call centre
- Increase payment points and transition away from cash
What we delivered
New regulations focussed on combatting electricity theft. Energy courts and a legal team to improve the prosecution process. A billing and customer management system for KEK.
The Results
- Increased annual cash collections by +32%, from €74M to €97M.
- Increased collection against billed percentage from 58% to 79%.
- Reduced total losses from 59% to 48% representing a 18.6% improvement over two years.
- Reduced debtor days by more than 60%.
What we do
We offer a comprehensive range of solutions for both public and private clients, right through the life cycle of their projects and the energy value chain.
