General Description

The rapid growth of battery energy storage systems (BESS) and hybrid assets combining renewable generation with storage is reshaping energy markets. These assets offer unique opportunities to unlock additional value through arbitrage, balancing services, and ancillary markets. However, fully capturing this potential requires advanced optimization capabilities and precise operational control.

Unlike pure generation or consumption assets, storage systems must dynamically manage both charging and discharging decisions while respecting technical constraints, degradation limits, and grid requirements. Operating across multiple markets and time horizons adds further complexity, making manual or fragmented approaches inefficient and risky. For asset owners and operators, relying on a specialized energy management partner becomes a strategic choice to maximize revenues while ensuring compliant, reliable operations.

Gnarum provides an advanced Energy Management Service specifically designed for hybrid and stand-alone storage assets. Our solution integrates forecasting, analytics, optimization, and automated trading into a single intelligent workflow, enabling assets to operate at their highest economic potential across energy and ancillary service markets.

The platform generates and executes optimized bidding strategies by synchronizing charge and discharge planning, curtailment and dispatch decisions, and multi-market revenue stacking, all while accounting for technical constraints, grid code requirements, and asset longevity. Through seamless automation—from market and asset forecasting to bid submission and real-time control—Gnarum ensures scalable, robust, and performance-driven management of complex storage portfolios.

Our client profile

The client is an energy market operator acting as both BRP and BSP for a 5 MW Battery Energy Storage System (BESS). The asset actively participates in energy markets as well as ancillary and balancing service markets, with the objective of optimizing overall economic performance through multi-market participation. To achieve this, the client requires a solution capable of coordinating trading decisions with real-time asset control, while ensuring full compliance with market rules and grid code requirements.

Our challenge

Managing a BESS across energy and service markets introduces significant operational and strategic complexity. The client must continuously optimize charging and discharging strategies, manage state-of-charge constraints, and respond to market signals in real time, all while limiting battery degradation and ensuring regulatory compliance. Additionally, acting as both BRP and BSP implies direct responsibility for operational performance, financial exposure, and communication with TSOs and market operators. The key challenge was to integrate advanced market optimization with real-time asset control in a single, reliable framework capable of maximizing revenues without increasing operational risk.

Gnarum’s Solution

Gnarum delivers a fully integrated energy management solution that connects the BESS directly to its Energy Management and Control Room. The asset is continuously monitored and actively controlled, allowing charge and discharge profiles to be modulated in real time according to market opportunities and system needs, while remaining fully compliant with grid code requirements.

Our optimization engine combines high-accuracy price and power forecasts with detailed asset modeling to generate optimal bidding and dispatch strategies across day-ahead, intraday, balancing, and ancillary service markets. State-of-charge–driven dispatch logic and degradation-aware cycle planning ensure that economic performance is maximized while preserving long-term asset value.

Through automated trading and direct market connectivity, Gnarum manages the full execution process—from strategy definition to bid submission and performance monitoring. By integrating advanced analytics, intelligent automation, and real-time control, Gnarum enables the client to operate the BESS efficiently, securely, and profitably as an active market participant, unlocking the full value of storage in an increasingly dynamic energy landscape.
