Fortis Energy describes its ready-to-build portfolio across Albania and Serbia as combining 375 MWp of solar capacity with 112 MWh of storage, but its two listed projects account for 345 MWp, leaving a 30 MWp gap. The listed solar figures do not match the portfolio total, while the storage figures do. Corporate renewable power purchase agreements (PPAs) in Southeast Europe are moving toward delivery profiles designed to track industrial demand more closely than pay-as-produced solar output.
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 total 345 MWp of solar and 112 MWh of storage.
The proposed product is a renewable block with defined shaping capability, transparent limits and optional market top-up, positioned between pay-as-produced solar and a fully firm PPA. It is not true 24-hour baseload supply from a single solar plant. The storage volumes in the portfolio are too small to convert the full generation profile into baseload, but can shift output into the most commercially useful hours.
For corporate buyers, shaped delivery can reduce exposure to expensive evening purchases and lower imbalance. For sellers, shifting some output can protect solar generation 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; storage makes the shaped renewable PPA possible.
