Fortis Energy’s ready-to-build portfolio in Albania and Serbia is stated to include 375 MWp of solar capacity and 112 MWh of storage, while its two listed projects total 345 MWp of solar. The difference leaves a 30 MWp gap between the stated portfolio capacity and the project figures.
In Albania, Erseke comprises 75 MWp of solar capacity and 40 MWh of storage. In Serbia, Nocaj comprises 270 MWp of solar and 72 MWh of storage. Together, the projects account for the portfolio’s stated 112 MWh of storage, but not its stated solar capacity.
Shaped renewable PPAs and storage
The portfolio figures come as corporate renewable PPAs across Southeast Europe move towards shaped green electricity. These contracts use delivery profiles designed to align more closely with industrial demand than solar power supplied on a pay-as-produced basis.
Storage can shift output to commercially useful hours, but the volumes in Fortis Energy’s portfolio are too small to convert the full generation profile into 24-hour baseload supply. The proposed product is not a baseload commitment from one solar plant; it sits between pay-as-produced solar and a fully firm PPA, combining a defined renewable block with shaping capability and optional market top-up.
Shaped delivery can help corporate buyers reduce exposure to expensive evening purchases and lower imbalance, while sellers can shift some generation to protect output from low midday capture prices. Under this model, the battery is a tool for shaping the contract rather than a standalone profit centre.
Contract terms and delivery risk
Contract terms should state whether storage is dedicated to the buyer or shared with merchant markets, how charging losses are allocated and what delivery tolerance applies during periods of poor renewable conditions. A fixed baseload commitment without sufficient firming capacity can create more imbalance risk than it removes. Storage makes the intermediate shaped-renewable product possible.
