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 the two listed projects total 345 MWp of solar. That leaves a 30 MWp gap between the portfolio figure and the project capacities.
In Albania, Erseke has 75 MWp of solar capacity and 40 MWh of storage. Serbia’s Nocaj project comprises 270 MWp of solar and 72 MWh of storage. Together, the projects total 112 MWh of storage, matching the portfolio figure, but their combined solar capacity does not match the stated total.
The figures come as corporate renewable power purchase agreements in Southeast Europe move towards shaped green electricity. These delivery profiles are designed to align more closely with industrial demand than pay-as-produced solar output.
Shaped delivery and storage in renewable contracts
Storage can shift output into commercially useful hours, but the volumes in Fortis’ portfolio are too small to convert the full generation profile into 24-hour baseload supply. The proposed product is not a baseload commitment from a single solar plant; it sits between pay-as-produced solar and a fully firm PPA, combining a defined renewable block, shaping capability and optional market top-up.
For corporate buyers, shaped delivery can reduce exposure to expensive evening purchases and lower imbalance. Sellers can shift some generation to protect solar output from low midday capture prices. Under this model, the battery acts as a contract-shaping tool, rather than a standalone profit centre.
Contract terms should clarify whether storage is dedicated to the buyer or shared with merchant markets, how charging losses are allocated and what delivery tolerance applies during 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.
