Fortis Energy’s ready-to-build portfolio across Albania and Serbia is described as combining 375 MWp of solar capacity with 112 MWh of storage, but its two listed projects total 345 MWp of solar. That leaves a 30 MWp gap between the project figures and the stated portfolio total. The listed storage capacity, by contrast, matches the portfolio total.
In Albania, the Erseke project comprises 75 MWp of solar and 40 MWh of storage. Serbia’s Nocaj project comprises 270 MWp of solar and 72 MWh of storage. Together, the projects account for 112 MWh of storage, but only 345 MWp of solar against the portfolio’s stated 375 MWp.
The figures come as corporate renewable power purchase agreements (PPAs) in Southeast Europe move toward shaped green electricity, with delivery profiles designed to match industrial demand more closely than pay-as-produced solar output. The Fortis portfolio’s storage volumes are too small to turn its full generation profile into 24-hour baseload supply, but can shift output into commercially useful hours.
The emerging product is not a baseload promise from a single solar plant. It sits between pay-as-produced solar and a fully firm PPA: a renewable block with defined shaping capability, transparent limits and optional market top-up. Storage makes that intermediate product possible.
For corporate buyers, shaped delivery can reduce exposure to expensive evening purchases and lower imbalance. Sellers can use it to protect some solar output from low midday capture prices. In this model, the battery is a contract-shaping tool rather than a standalone profit centre.
Contracts should specify 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 promise without enough firming capacity can create more imbalance risk than it removes.
