Planned energy projects in Bosnia and Herzegovina to 2031
Year-by-year overview of announced solar, wind, battery, data center and grid projects in Bosnia and Herzegovina from 2027 to 2031, with status and sources.
The short version
Gridscouter tracks 22 announced projects in Bosnia and Herzegovina for 2027–2031: about 660 MW of new solar, about 330 MW of new wind, two data center campuses in Mostar, and seven grid upgrades. Each item on the map links to its public source.
2027: first solar and storage at coal sites
The Sokolac / Glasinac solar park (100 MW, permitted) and Gračanica 1 & 2 near Bugojno (45 MW, contracted) are the largest solar projects due this year. At the Kakanj and Tuzla thermal plants, small solar and battery units are planned as utilities start reusing coal sites.
On the grid side, the 400 kV Višegrad – Bajina Bašta line is part of the Trans-Balkan Corridor and will strengthen the link to Serbia.
2028: Herzegovina gets more grid
The 220 kV Trebinje – Zupci line and the new TS Zupci substation are tendered. Trebinje 3 solar (54 MW) and Dubovik solar at Krupa na Uni (90 MW) follow. The NOVERIX AI campus at Aluminij Mostar announced a first phase of 50 MW.
2029: the big year for wind
Poklečani (132 MW), Bitovnja (90 MW) and Hrgud (60 MW) wind farms come with their own 110 kV substations and lines. Bileća 1 adds 270 MW of solar with storage under a signed concession. A second data center in Mostar (AAFS, around 100 MW) has been announced, but its exact site is not public.
2030–2031: interconnection
Vlašić wind farm (50 MW) has a signed concession. The 400 kV Banja Luka – Lika interconnector to Croatia is still under consideration and would be the largest new cross-border link.
What this means for developers
New solar and wind in Herzegovina will compete for the same substations. Battery storage next to those substations becomes more valuable as solar grows, which is why the BESS ranking on Gridscouter changes with the year you pick.
Years are estimates based on announcements and can slip.
