We are constantly improving our systems to keep energy costs as low as possible for our customers. Imbalance costscan add up significantly for solar parks and consumers, especially duringcontrol state 2. This is a situation where both a shortage and a surplus of electricity occur within a 15-minute period. During such periods, the market becomes unbalanced, and all parties with an imbalance position are subject to imbalance costs from TenneT.
To limit these costs, wehave been applyingtheRepowered Portfolio Benefitsince January 2026.
How does the Repowered Portfolio Benefit work?
The Repowered Portfolio Benefit reduces energy costs during periods with control state 2 in two ways:
- Offsetting within the Repowered portfolio
Each customer’s connection is part of the Repowered portfolio. This allows usto (partially) offset differences between customers. If one customer generates slightly more than expected and another customer consumes slightly less, these differences partially offset each other. This reduces the individual negative effects of imbalance and lowers costs for both parties. - Ex-post automatic trading
In addition, we use fully automated trading in theex-post market. In this market, imbalance positions can be exchanged with other parties after the fact, resulting in further cost reductions.
The principle is simple: the larger your portfolio with Repowered and the greater your production or consumption during control state 2, the more compensation you receive through the Repowered Portfolio Benefit.
