Decarbonisation Services

Optimise the whole system from power plant to grid

Do you have to deal with complexity, conflicting goals, grid instability, decarbonisation and financial pressure?

The energy industry is faced with systemic challenges that can only be solved by optimising the whole system from power plant and energy storage to grid – and increasing and optimising the use of renewables. This is a complex task that requires a holistic approach, but it delivers multiple benefits.

Let Decarbonisation Services help you achieve your goals by finding the optimal balance between commercial, operational and ESG (Environmental, Social and Governance) factors. With outcome-based agreements, you can be certain that we will only recommend what you really need – and go the extra mile as our fee is linked to your success.

How we optimise to decarbonise

 

Let us diagnose your unique challenge, model the optimal yet feasible solution, and implement it with our GEMS Digital Energy Platform.

Our holistic approach offers you all the services, equipment, software and support you need every step of the way over the whole lifecycle.

Helping you supply affordable energy while meeting your commercial, operational and ESG targets.

    Step 1: Diagnosing your challenge

    We use our industry understanding and power system modelling tools and capabilities to identify your challenges whether current operational or future ones brought on by renewable integration. 

    Step 2: Modelling the optimal solution

    We model both the optimal solution to meet your needs and its feasibility using techno-economic analysis (cost optimisation / minimisation) and dynamic simulations (frequency and voltage stay within limitations). We strive for as accurate real-world conditions as possible.

    Possible battery, engine or other additions

    When modelling the optimal solution, we consider the future needs of the system and help you plan capacity additions.

    Technical feasibility

    We verify the technical feasibility of our modelled optimal solution by considering various factors that affect the grid.

    Technical implementation

    We use simulations to do one-final test on our optimal solution to ensure it is easy to deploy. 

    Step 3: Implementation

    The solution and support will be implemented with GEMS, our Digital Energy Platform, and a lifecycle agreement.

    Our performance in achieving your targets is tracked, and our fee is linked to your targets as defined in the outcome-based service agreement.

    Customer reference: Powering Curaçao’s Energy Transition

    Aqualectra and Wärtsilä: A Partnership Driving Decarbonisation

    Curaçao is on an ambitious journey to transform its energy landscape—moving from 30% renewable capacity to 70% by 2027. At the heart of this transition is Aqualectra, the island’s trusted energy utility, and Wärtsilä, a global leader in flexible power solutions. Together, they’re shaping a cleaner, more resilient future for over 80,000 households and businesses.

    For over 30 years, Wärtsilä has worked hand-in-hand with Aqualectra, evolving from power generation to a pioneering Decarbonisation Services agreement. Today, this collaboration includes advanced grid balancing engines, energy storage systems, and Wärtsilä’s GEMS Digital Energy Platform—optimising energy use across the island. The result? Affordable, reliable, and sustainable electricity for Curaçao’s residents.

    Together, we are building a blueprint for resilient and sustainable island energy systems worldwide.
