Isotrol takes a major step forward in its business model with the launch of Bluence BESS Optimizer, its high-value, innovative software for the management and optimization of electrical storage systems. The solution was unveiled at the GENERA 2025 trade fair in Madrid and represents the company’s most advanced development to date, aimed at anticipating the needs of operators who are beginning to integrate batteries into their renewable generation portfolios.
Bluence BESS Optimizer determines in real time when to charge or discharge a battery by applying strategies based on price forecasts, state of charge, and consumption. These calculations are managed by algorithms that automate operational decisions, indicate which market to participate in, prolong battery lifespan, and maximize revenues. The tool is also designed to integrate seamlessly with automated energy-trading systems.
Such solutions are essential to ensure the economic viability of batteries in a context where electricity prices can swing from zero to more than €150/MWh within hours. As a result, they make storage investments far more attractive in an Iberian market nearing saturation of renewable installations.
In this regard, Isotrol’s solutions aim to accelerate the adoption of storage software.
“We want to offer solutions capable of connecting plant-level operations with the energy market. We are positioning Isotrol as a benchmark within this new operating ecosystem for batteries,” explains José García Franquelo, Director of Innovation at Isotrol.
Bluence BESS Optimizer is built on in-depth knowledge of both battery control systems and Iberian market trading. It has been designed to incorporate new markets gradually—an ability that, according to Mario Fito, SVP Energy Trading at Isotrol, is “one of the key elements needed to become a reference player in this emerging field.”
“Operating in electricity markets requires explicit adaptation—investment and years of research for every step forward. The fact that Bluence has been designed as a platform capable of integrating several markets simultaneously makes it a unique solution,” Fito adds.
Controlling storage ant the wholesale market
Bluence BESS Optimizer is part of a broader strategy that Isotrol began more than a decade ago with the development of energy-trading solutions. Its goal: to connect plant operation with market activity.
“Today, Bluence BESS Optimizer and Bluence Trading work together to deliver a comprehensive solution. BESS Optimizer plans battery charge and discharge, maximizes revenues, and preserves battery lifetime, while Trading markets that energy by combining operator expertise with the robotic power of our platform,” Franquelo explains.
The optimizer adapts to these adjustments to ensure coherence with previous commitments.
Bluence Trading is designed to give market participants the ability to operate automatically, using complex yet easy-to-configure strategies. Its algorithms replicate in real time the decisions of an expert trader, but with machine-level speed. With the recent addition of new services, Bluence Trading now completes the full market cycle and focuses on strengthening its integration with Bluence BESS Optimizer.
By automating the daily trading cycle, Bluence Trading significantly reduces traders’ workload. Its multi-market approach enables simultaneous analysis of different electricity markets to seize the best opportunities—replicating, in the energy sector, what already happens in the stock market. Its scalable design allows both large generators and smaller operators to benefit from its power and speed.
