Projects
Pilot and renewable energy projects
Implemented installations, prepared initiatives and feasibility studies.
120 kW hospital solar project
A 120 kW solar PV system was installed for a city tuberculosis hospital. The system was integrated with the facility’s existing generator into one operating system. Battery storage was not included.
Status: Installed.
View project506 kW distributed public-sector solar project
A 506 kW solar PV project was implemented across multiple locations, including lyceums, hospitals, educational institutions and other public facilities.
Status: Implemented across multiple sites.
View project468 kW distributed public-sector solar project
A second 468 kW solar PV project was implemented across multiple public-building and social-infrastructure locations.
Status: Implemented across multiple sites.

100 kW Prosecutor’s Office solar project
A 100 kW solar PV system was developed and installed for the Prosecutor’s Office.
Status: Installed.
View projectPumpėnai Citizen Energy Community
Pumpėnai is Lithuania’s first operational Citizen Energy Community model. Its existing 36 kW solar PV plant has a planned expansion to approximately 99 kW. Battery storage and a small wind turbine of up to approximately 30 kW are planned for the next development phase and are not operational.
Status: 36 kW plant operational; expansion and the next development phase are planned.
View projectFirst Citizen Energy Community initiative
A Lithuanian energy-community model has been adapted for Moldova. The community structure and project concept have been prepared, a funding application has been submitted, and the initiative is awaiting financing before implementation.
Status: Initiative and concept prepared; funding decision pending.
View projectFirst Citizen Energy Community initiative
A first-of-its-kind Citizen Energy Community initiative in Ukraine, based on the Lithuanian model. The legal and project concept has been developed, funding applications have been prepared, and implementation is planned once financing is secured.
Status: Initiative and concept prepared; financing required before implementation.
View projectFloating Solar for flooded quarries
Feasibility work carried out with Kaunas University of Technology to assess floating solar PV on former quarry sites that are no longer operational and have filled with water.
Status: Feasibility study.
View projectFloating Solar for small hydropower reservoirs
Two feasibility studies assessed how floating solar PV could complement small hydropower plants. Hydropower output is often higher in spring and autumn, while solar production peaks in summer, when water flow and hydropower generation may be lower.
Status: Two feasibility studies.
View projectFloating Solar for aquaculture facilities
A feasibility study with Kaunas University of Technology assessed floating solar PV deployment on water surfaces used by fish-farming operations.
Status: Feasibility study.

Solar-as-a-Service
OKATA has developed Solar-as-a-Service project structures in Ukraine and Uzbekistan. The beneficiary does not make the upfront investment in the solar plant. The project developer finances and installs the system, while the beneficiary purchases the electricity it generates for an agreed period at a price discounted from the prevailing market price.
