Impact
Could there be contractual limitations in the injection contract with the supplier that affect flexibility or curtailment options?
Yes. Certain contracts restrict curtailment, as it impacts supplier forecasting and nominations. However, this is rarely a dead end. AYA supports clients in assessing and renegotiating such contracts to unlock curtailment opportunities and secure the right supplier setup.
If your solar installation peaks above 1 MW, there’s a good chance it’s losing value right now. Negative electricity prices are turning daytime production into a liability, and the cost is rising fast.
But with the right setup, you can avoid those losses and unlock up to €30K per MWp.
As energy became more and more complex over the years, Decathlon went in search of a reliable partner.
Michiel Goetschalckx, construction and energy manager at Decathlon, comments. ‘We were looking for a party that thinks along with us in terms of strategy, sustainability and innovation. AYA ticked off all those priorities. Based on our needs, they outlined the strategy. In the process, we also investigated off-site renewable energy options to complement our traditional energy consumption on-site solutions.’

Solar That Costs Instead of Pays
Solar plays a vital role in decarbonising our energy system. But when too many installations inject at the same time — especially on sunny days — the grid gets saturated. Prices crash, and clean energy turns into a cost.
In 2024 alone, the number of hours with negative electricity prices more than doubled, mostly during peak solar production. If you’re running more than 1 MW of PV, this is no longer a theoretical risk — it’s probably already impacting your revenue.
This price volatility flips the logic of traditional solar operations. Producing energy when it’s least needed doesn’t just reduce your return, it can lead to penalties.
That’s why PV curtailment has become a strategic necessity. But not just any curtailment: one that’s guided by market conditions, not fixed rules.
The Solution: Market-Based Curtailment by AYA
AYA’s market-based PV curtailment takes a smarter route. It uses real-time price signals to dynamically steer your injection — avoiding negative prices without shutting down completely.
✔ No infrastructure changes
✔ No full system shutdowns
✔ Direct return from day one
This approach doesn’t just protect you from losses, it adds a new flexibility revenue stream on top.
Where the Value Comes From
AYA’s approach unlocks value across multiple market layers:
- Day-ahead & intraday markets – Avoid losses during low or negative price periods.
- Imbalance market – Get rewarded for reducing injection when the system is oversupplied.
- aFRR market – If technically ready, participate in real-time system balancing.
Installations using curtailment in this way have increased their revenue by up to 30%, compared to static operations.
For companies with >1 MW peak PV, this is a high-impact, low-barrier solution. The software installs quickly on top of your existing setup and immediately begins optimising around market conditions.
In the short term, this can mean up to €30,000 per MWp per year in added value.
Long term, market-based curtailment is a stepping stone toward broader flexibility strategies, including batteries, e-boilers, and coordinated load shifting.
