The Baltic Hybrid Park sits on 340 hectares of reclaimed peat pasture near Mažeikiai in northern Lithuania, roughly 40 km from the coast. When our client, Nordbalt Renewables, first modelled the site in 2023, the wind resource was strong but seasonal, and a standalone PV plant would have spent much of its output curtailed behind a congested 110 kV feeder. The question was not whether wind or solar performed better here, but whether we could make them share one connection and one balancing profile.
We built it as a single asset: 78 MW of turbines and 96 MWp of bifacial PV sharing a 90 MW grid connection, with a 20 MW / 40 MWh battery smoothing the handover between the two resources. Because our engineering, procurement and construction teams sit under one roof, the wind foundations, cable trenching and tracker piling were sequenced against a single construction programme rather than three subcontracts pulling in different directions.
The numbers
For the quarter running April through June 2026, the park delivered a blended capacity factor of 34% against a modelled 31%, producing 130 GWh across the three months. Wind carried the spring gales; PV filled the long Baltic daylight hours as the nights shortened toward midsummer. The two profiles overlapped far less than a single-technology plant would, which is precisely the point of co-location.
The shared connection ran at a 96% utilisation factor. On a standalone basis, either plant alone would have left the 90 MW line idle for most of the year; together they kept it working. Curtailment came in at 2.1% of gross generation, well under the 5% we had underwritten, and the battery clipped fewer than 30 peak events rather than the 50-plus in our base case.
The commercial result matters as much as the physics. Because wind and PV rarely peak together, the combined feed-in was steadier, and Nordbalt captured a higher average price per MWh than either technology would have earned selling into the Nord Pool day-ahead market on its own. Fixed costs — the substation, the grid upgrade, the access roads, the O&M contract — are now spread across two revenue streams instead of one.
There are caveats we are watching. One full quarter is not a full year, and a summer with weak wind and heavy cloud would test the model harder than these three months did. We will report again after the first winter, when short days and Baltic storms invert the balance. For now, the hybrid thesis is holding: one connection, two resources, a steadier output, and a capacity factor three points above plan.
