Powering Lithuania’s Energy Future: How ESO Scaled Digital Operations with ARKANCE

Scaling Digital Operations for an Electricity and Gas Distribution Network 

Energijos skirstymo operatorius (ESO), a company within the Ignitis Group, is responsible for ensuring reliable electricity and gas distribution for Lithuania’s population and businesses. ESO operates and maintains more than 130,000 km of electricity overhead and cable lines and over 9,600 km of gas pipelines, strengthens network reliability, installs smart solutions, handles fault restoration and connects new customers to the grid. It also provides guaranteed electricity and gas supply services. 

Managing this scale of operations requires not only physical infrastructure but also strong, integrated digital tools that support large numbers of internal and external stakeholders, ensure transparent contractor management and enable effective planning of network investment projects. 

For the past decade, ARKANCE has supported ESO in building this digital foundation. 

“We started working together in 2016. Since then, ARKANCE has successfully retained the contract five times. Our partner is very reliable,” says Vilma Beinorienė, Team Manager of the Asset Management Systems Team within ESO’s Digital Solutions and Data Management Department.

Out of around 2,700 employees at ESO, only a small team is responsible for developing asset management IT systems. This team is responsible for six systems in total, two of which—TIVIS and the Contractor Portal—are developed together with ARKANCE.

In 2026, the two organizations mark ten years of collaboration built on trust, responsiveness, and continuous improvement. 

The number of prosumers continues to grow rapidly as well, with more than 175,000 customers already producing their own electricity, making Lithuania one of the most dynamic renewable energy markets in the region. 

While these achievements reflect the wider transformation of Lithuania’s energy system, the digital solutions developed with ARKANCE specifically contribute to network investment management and coordinated contractor operations, supporting ESO’s ability to carry out this modernization efficiently and transparently. 

Digitalization as a Foundation 

The transition to integrated digital systems required not only technical changes but also cultural adaptation and new ways of collaborating. “Both sides came with different experiences and encountered daily challenges, but we always worked towards a shared result,” Vilma explains. 

To bridge gaps in understanding, ARKANCE invested time in learning ESO’s operational specifics, regulations and contractor ecosystem. Through close cooperation and iterative development, complex requirements were transformed into practical, scalable and user-friendly systems. 

A key factor in successful adoption was the decision to start with a fully tailored system in a core department and to appoint superusers who supported colleagues during the transition. This helped create ownership and confidence in the new tools. 

Creating a Unified Digital Foundation 

Since 2016, ARKANCE has been providing bespoke development and long-term maintenance for two systems within ESO. The first of these, TIVIS, is ESO’s core network investment management system. It supports the full scope of network investments processes, including project design, construction activities. It also enables the management of contractor agreements and tasks, while allowing ESO teams to track work progress, materials, costs and results. In addition, TIVIS integrates with other ESO platforms to ensure that data remains synchronized throughout every stage of a project. 

Delivering Operational Impact 

The long-term partnership has evolved from initial development to continuous optimization, resulting in measurable improvements across ESO’s operations: 

Driving Efficiency and Control 

• Broader and more efficient administrative workflows 

• Reduced email overload with user‑controlled notifications 

• Full traceability of design and contractor tasks

• Smooth data synchronization between TIVIS, the Contractor Portal and other ESO’s system. 

Strengthening Oversight 

• Standardized management of network investment projects 

• Enhanced quality assurance and regulatory compliance 

• Real‑time transparency into contractor performance 

Together, these systems form a scalable digital platform that supports Ignitis Group’s green transition goals and the modernization of Lithuania’s electricity and gas distribution network.

A Partnership Built to Last 

ARKANCE continues to support ESO through long‑term collaboration focused on system stability, continuous improvement and the development of new digital capabilities. As regulatory requirements increase, the need for strong traceability and oversight grows — and the systems developed jointly help ensure quality assurance and governance across ESO’s network investment operations. 

What began as a software engagement has become a trusted partnership. 

After ten years of collaboration, the partnership now plays a meaningful role in supporting ESO’s digital development and the modernization of Lithuania’s energy network infrastructure.
