Hybrid Parks and Multi-Market Optimisation in Renewable Energy

Hybrid renewable energy parks are transforming how value is created in modern electricity markets. As grid congestion and price volatility increase, combining wind, solar and battery storage into a single flexible system is becoming a strategic advantage rather than an optional optimisation.

These dynamics were explored during Energy Week Black Sea 2026, where new approaches to asset optimisation and revenue stacking were presented through real-world examples.

From standalone assets to integrated systems

Riku Kukkonen, Co-Founder and Chief Sales Officer of Capalo AI, presented a data-driven model for hybrid asset optimisation.

Instead of treating wind, solar and battery energy storage systems as separate assets, Capalo AI integrates them into a single system operating behind one grid connection point.

This approach allows hybrid renewable energy parks to maximise the use of limited grid capacity while reducing exposure to curtailment and connection delays.

Multi-market participation as a value driver

At the core of the model is multi-market participation.

Hybrid assets can simultaneously operate across day-ahead, intraday and balancing markets, including automatic Frequency Restoration Reserve (aFRR) and other ancillary services.

When price volatility is low, renewable generation drives revenues. When volatility increases, batteries become the primary source of value.

This flexibility enables hybrid renewable energy parks to optimise revenue streams while managing risk across different market conditions.

Solving grid congestion through hybridisation

One of the most pressing challenges in South-East Europe is grid congestion.

By adding storage behind existing wind or solar connections, developers can significantly improve the utilisation of available grid capacity. This reduces curtailment risk and enhances project bankability without waiting for new transmission infrastructure.

In this context, hybrid renewable energy parks provide a practical solution to one of the key bottlenecks facing renewable deployment.

The complexity of real-time optimisation

Operating hybrid assets requires advanced optimisation capabilities.

A single connection point must balance multiple variables, including:

• charging and discharging constraints
• market price signals
• battery degradation and warranty limits
• opportunity costs across markets

Capalo AI’s platform integrates price forecasts, weather data, grid conditions and asset-specific technical parameters to continuously optimise dispatch decisions.

This level of sophistication is essential for unlocking the full potential of hybrid renewable energy parks.

Strong revenue potential in volatile markets

Real-world performance data highlights the commercial value of this approach.

In highly volatile markets such as the Baltics, hybrid and storage assets generated monthly revenues exceeding €50,000 per MW during peak periods in 2025.

Romania was identified as particularly well suited to these strategies, given its combination of high day-ahead prices and significant balancing market volatility.

Hybrid parks as a financial solution

A key takeaway from the discussion is that hybridisation is not just a technical solution, but a financial one.

By combining generation and storage into a single flexible asset, developers can:

• improve revenue stability
• reduce exposure to single-market risk
• enhance bankability and lender confidence

This directly addresses broader concerns around grid access, investment risk and capital discipline raised throughout Energy Week Black Sea 2026.

The future of renewable asset optimisation

As renewable penetration increases and market dynamics become more complex, the ability to optimise across multiple markets is becoming essential.

Hybrid renewable energy parks, supported by advanced optimisation platforms, are emerging as one of the most effective pathways to making renewable energy both system-friendly and investment-ready in the Black Sea region.
